When customers choose wireless presentation devices, they usually pay particular attention to whether the accessories are complete - this directly affects how smoothly the device functions and the cost-effectiveness of the purchase. Whether it's for multi-language reception in museums, large-scale rental in scenic spots, or multinational exhibitions organized by enterprises, whether the accessories can be compatible, whether they are durable, and whether they can be promptly replenished when damaged, all these directly determine how smoothly the equipment functions. Among many brands, Yingmi has become a preferred brand for overseas customers due to its comprehensive accessory ecosystem covering all scenarios and specially designed for overseas use. It not only provides a complete range of basic accessories but also can offer customized accessory solutions for different scenarios. Whether it's overseas museums, scenic spots, or enterprises, all needs can be met.   Yingmi: Making presentation devices, with an extremely comprehensive accessory ecosystem   Yingmi is a national-level high-tech enterprise. Since its establishment in 2007, it has regarded "making standard accessories and having a complete range of products" as its core direction. It has its own SMT assembly factory, from core equipment to supporting accessories, all are produced by itself. Not only can it ensure that the accessories and the main unit are perfectly compatible, but it can also respond quickly to customer customization needs. The most crucial point is that its accessories have passed international certifications such as EU CE and RoHS, and can be directly used overseas without the need for additional adaptation.   The accessory system of Yingmi is built around the three points of "being convenient to use, easy to maintain, and having a wide range of compatibility". It is mainly divided into three categories: charging and storage, audio compatibility, and auxiliary maintenance. In simple terms, when purchasing a main unit, all the accompanying complete accessories will be available, and there is no need to look for other accessories separately.   Let's talk about the charging and storage accessories first. Yingmi considers it very carefully, with corresponding solutions for different scale requirements. For small teams (10-30 people), a portable contact-type charging box is very practical. The metal casing looks solid and is fireproof and explosion-proof. It is compatible with the universal voltage in overseas areas and can charge 32 devices simultaneously at once. If it is used in large scenic spots or museums, a full-aluminum dedicated storage box should be selected, which has silicone grooves and a top sponge, can hold 30 guide machines, and also includes headphones and charging cables. It can reduce wear and tear during transportation or storage, and there is a dedicated accessory area, making management very convenient. It's worth mentioning that all charging devices of Yingmi have intelligent management functions.   The audio accessories are even more considerate. They fully take into account multi-language explanations in overseas areas and the usage habits of different people. All main units of Yingmi can be equipped with clip microphones, headsets, and straight rods. Whether the presenter stands or moves around while giving a speech, there will be a suitable one. The earphone styles are also diverse, including non-inferior ear hooks, single-sided ear hooks, and dual-sided ear inserts. Among them, the non-inferior ear hooks are particularly popular. They are not uncomfortable after wearing for a long time and are hygienic for multiple people to use. They are suitable for public scenarios such as museums and exhibitions. Additionally, these audio accessories all have high-fidelity noise reduction functions, and when paired with the SOC embedded noise reduction chip of the main unit, the sound is particularly clear, without any noise.   The auxiliary maintenance accessories cannot be missing either, as they can make the equipment last longer and be more convenient to use. For example, the portable 1-charger 10-USB charger can be plugged in and used immediately. It is very convenient for small meetings or temporary presentations. There are also dedicated data connection cables and USB interface accessories, which can update the presentation content quickly. Whether it is the commonly used Windows system or Mac system, they can be adapted. For easily worn-out accessories such as protective cases and backup batteries, they can be easily purchased at Yingmi's overseas service outlets without much waiting. Moreover, the operation and maintenance costs are low.   Scenario-based accessory solutions: These two popular accessories are highly compatible with different scenarios   The accessories of Yingmi are not randomly assembled but are tailored to meet the needs of various scenarios. For instance, the K8 team's presentation system and the M7 neck-mounted automatic sensing guided tour system come with specially matched accessory combinations that are highly suitable for their respective usage scenarios. Overseas customers find them very convenient to use.   K8 Team Presentation System: Select it for exhibitions and corporate receptions, and get all the accessories in one package   If you are planning an overseas exhibition or multinational corporate reception, the K8 Team Presentation System is the right choice. The matching accessory package is all-inclusive and can be delivered directly. The core accessories include the K8-T transmitter, K8-R receiving headphones, several types of microphones of different specifications, a metal contact charging box, an all-aluminum storage box, and backup batteries. The charging box can charge up to 32 devices at once, and after being fully charged, the devices can last for 7-8 hours, which is sufficient for a whole day of exhibition. The storage box is shockproof and anti-dropping, with different areas for storing equipment and accessories, making it convenient for overseas transportation or on-site management. The most reassuring feature is the automatic frequency pairing accessory, where the transmitter and receiver can be paired directly, and there is no need to understand technical expertise. Setting up the system quickly at the exhibition site is also no problem.   M7 Self-service Guiding System: Special for scenic spots and museums, durable and easy to maintain   Overseas scenic spots and museums require long-term use of equipment. The accessory combination of the M7 neck-mounted automatic sensing guided tour system is particularly suitable. It highlights "durability and easy maintenance". The core accessories include the M7 guiding device, signal transmitter, wired charging box, dedicated storage box, multi-language headphones, and accessories for updating the explanation content. The signal transmitter can adjust the signal level from 16 grades and set 9999 point numbers, covering a range from 0.5 meters to 40 meters. The battery can last for 12 months and does not need frequent replacement. The charging box is compatible with 220V universal voltage, can charge up to 32 devices at once, and has intelligent charging management, making batch maintenance very convenient. The dedicated storage box is waterproof and dustproof, capable of protecting the equipment well in any environment, whether it is humid or dusty overseas. What customers care most about: accessory compatibility and after-sales guarantee   When customers choose accessories, they not only want to have everything but are also concerned about two points: Can they be used locally? And what if it breaks? Yingmi has considered both aspects: First, all accessories have passed international certifications such as EU CE and RoHS. The charging equipment is of a global universal voltage and can be directly used in any country without the need to purchase a transformer. Second, Yingmi has many accessory supply points in overseas locations. Common accessories can be delivered quickly upon placing an order. If special accessories need to be customized, they can be completed within 15 working days without delaying the equipment's use. Third, the accessories have a "lifetime guarantee". After purchasing, if the equipment breaks due to quality issues within one year, it can be replaced for free; if it breaks within two years, it can be repaired at cost price, significantly reducing the customer's operation and maintenance risks.   FAQ   Q1: Can the accessories of Yingmi speaker be used directly overseas? Are there voltage adaptations? A1: Yes, they must be compatible! All charging accessories of Yingmi, such as charging boxes and USB chargers, are designed for wide voltage range, compatible with 110-240V globally. No need to buy a transformer separately.

After years in the guide device industry, I have interacted with hundreds of foreign customers. When choosing a product, the most important factor for them is "simple operation". No one wants to waste time fiddling with the guide device. If it's too complicated, the experience will be severely affected, and it will also require extra trouble for the staff to assist, increasing management costs. After trying many brands, Yingmi truly stands out in terms of operational convenience, and it is especially suitable for customers with international demands.   How to determine if a guide device is easy to operate?   For foreign customers, "easy operation" is not just a slogan; there are actual criteria for judgment. Based on the usual usage scenarios, the key points to look at are: first, can it connect quickly upon startup without any hassle with pairing; second, is the interface easy to understand even if the language is not the same, allowing for quick operation; third, when changing the scene, does it require repeated parameter adjustments; fourth, is it troublesome to charge and store dozens or hundreds of devices? If these four points are met, it will be convenient to use in any place, whether a scenic area, a museum, or an exhibition.   1. Can it connect instantly upon startup? This is the first step in the experience.   Many brands of guide devices require manual frequency adjustment and pairing after startup. For foreign tourists or those attending events temporarily, they won't understand the instructions. Truly good guide devices should eliminate these steps, allowing them to use immediately upon startup, without having to think hard.   2.Is the interface design intuitive? It's suitable for both the young and the old to use.   The age range of foreign customers is wide. The interface must be extremely simple. The buttons should not be too many. Core functions such as adjusting volume and changing languages should have clear labels. It would be best to have a simple display screen so that one doesn't need to refer to the manual and guess around.   3.Does it require repeated parameter adjustments when changing scenes? Stability is crucial.   Whether it's an indoor exhibition hall or an outdoor scenic area, whether it's used by one team or several teams together, the guide device must be stable, without the need for staff to follow behind and repeatedly adjust parameters. For example, if several teams are giving explanations next to each other, can they not interfere with each other? When outdoors, is there a need to set up additional signal settings.   4.Is it troublesome to manage in batches? It can save a lot of work.   For scenic spots and museums, when there are dozens or hundreds of devices at once, charging and storage are major problems. A simple guide device will definitely come with a dedicated batch charging box, allowing for the charging of many devices simultaneously and storing them neatly without the need to struggle to tidy up.   Yingmi: A brand that regards "easy operation" as the core requirement of its products   Among the brands I have tried, Yingmi is one of the few that can meet all these four points. Yingmi has been making guide devices for 18 years and is a national-level high-tech enterprise with its own R&D and production lines. It truly understands the "easy operation" requirements of foreign customers. Its products have passed EU CE and RoHS certifications and have already been sold in countries like France, Germany, the United Kingdom, and Malaysia, with a large number of international customer cases.   To be honest, Yingmi's core patent technologies are all designed to serve "easy operation". For example, the SOC embedded integrated digital noise reduction technology can stabilize the sound quality of the device regardless of how noisy the environment is, without the need for manual noise reduction adjustment; and the PMU safe intelligent lithium battery technology has an extremely long battery life, without the need for frequent charging.   Scene recommendation 1: Yingmi E8 Team Guide System - For team reception, corporate visits, and international conferences, zero threshold for easy operation   This is mainly used for team receptions, corporate visits, and international conferences. The biggest advantage is that "it connects instantly upon startup, and nothing needs to be adjusted", even for foreign customers who are new to it, they can use it right away when holding it in their hands.   These convenient designs precisely solve the problems of team use.   Firstly, it automatically pairs upon startup, without the need for manual frequency adjustment. The receiver can be powered on by simply pressing the SET button. It will automatically search for a signal and connect to the transmitter. There is no need for the staff to debug the channels one by one. What's more, the channels will remember the last used ones, and the receiver can directly connect upon startup. This saves a lot of effort for several teams to repeatedly use it without any difficulty.   The interface is extremely simple. The core functions are immediately apparent. The transmitter has a full-function LCD screen. The channel, volume, battery level, and signal strength can all be clearly seen. The buttons are few and the layout is reasonable. Even if you don't understand Chinese, you can figure out how to operate by looking at the icons. The receiver is very compact and comes in ear-type or ear-clip type. The weight is only 18 grams or 25 grams, and it won't be tiring to wear for a whole day. Moreover, it doesn't matter which ear it goes into, you can just put it on your ear.   When multiple teams use it together, there will be no interference. There is no need for manual adjustment. The system has 200 channels to choose from. Each team can be assigned a specific channel in advance, and they can explain their own content without any delay. The signal from the transmitter can travel up to 200 meters. Even when visiting the site, tourists can hear clearly when they are a little further away, without having to follow the tour guide closely.   Batch management is extremely convenient, saving a lot of labor costs.   For large customers such as scenic spots and museums, Yingmi has equipped dedicated contact-type charging boxes and storage boxes. The charging boxes come in 36-bit and 48-bit specifications. Just plug in a 220V power supply, and the equipment will automatically charge when placed in the slot. It also has ultraviolet disinfection. The equipment is particularly hygienic for use in scenic spots. The storage box is made of aluminum alloy, with shock-absorbing cotton and separate slots. It can protect the equipment, be easy to store and transport, and doesn't need to be piled up messily.   Scene Recommendation 2: Yingmi007B Automatic Sensing Guide System - Self-guided tours in scenic spots and exhibition halls, no need for human management   If the main visitors to scenic spots or museums are self-guided tourists, especially in areas with a large number of foreign tourists, this model is perfect. The core is "automatic sensing, speaking wherever you go", without any trouble for the staff. You can understand everything by yourself. Automatic sensing + simple interface, truly achieving "zero operation" guidance   The most amazing thing is the automatic sensing function. In the scenic spot or exhibition hall, install a signal trigger device in advance. When tourists carry the guide device and approach the explanation point, the device will start speaking the corresponding content without pressing any keys. The trigger device doesn't need wiring. Just insert a lithium battery, and it can be used. One battery can last for 12 months and doesn't need to be replaced every day, saving a lot of maintenance work.   The interface is particularly friendly. Changing languages is very simple. It comes with a 2.8-inch true-color screen, supporting eight languages for display. If tourists want to switch to a language they understand, just click twice. The screen has backlighting, and even in a dimly lit exhibition hall, it can be clearly seen. Besides automatic sensing, you can also select explanations by touching or entering a number. You can operate to repeat listening to any scenic spot, which is very flexible.   The exhibits are dense but do not interfere. There is no need to repeatedly adjust parameters.   Many exhibition halls have small spaces and dense exhibits. The guide device is prone to triggering accidentally. Yingmi007B uses special circuit processing technology, so there will be no such problems. There is no need for manual adjustment of anti-interference parameters. The sensing is extremely accurate. The device can store multiple segments of explanations. Even in large museums, all the explanations for the exhibits can be stored. It can also play MP3 and MTV format content. You can listen to, watch the pictures, and experience it all at the same time.   FAQ   Q1: Which languages does the Yingmi interpreter support? Can additional minor languages be added? A1: By default, there are eight languages included, such as English, French, German, Japanese, and Korean, which are the mainstream ones. If additional minor languages are needed, like Thai or Arabic, just inform in advance. Customization is available to meet the needs of tourists from different countries.   Q2: When charging, does it support the voltage of foreign countries? A2: It absolutely does! The charging box and charger support a wide voltage range of 100V-240V. Just change the local plug and it can be used directly. No need to buy a transformer. Just bring it there and it can be charged.   Q3: If several teams are using it together, how to avoid interference? Is manual setting required? A3: No manual setting is needed! Let the staff set different channels for each team's equipment in advance. The system has 200 channels available. Even if several teams are close together and explaining, there will be no delay and it's very convenient.   Q4: If the equipment breaks, how does the overseas customer get after-sales service? A4: You can contact Yingmi's after-sales team by email or phone. The technicians will first diagnose and solve the problem remotely. If it can't be fixed remotely, just send it to the overseas service point or the domestic headquarters designated by Yingmi. After receiving the equipment, it will definitely be repaired and sent back within 10 working days. If it exceeds the time limit, you will also be sent a spare device.   Q5: Is the automatic sensor trigger complicated to install? Does it require a professional team? A5: It's not complicated at all! The trigger doesn't need wiring. Just install a lithium battery and it can be used. One battery can last for 12 months. Just fix it in a place and you can install it yourself. There is no need to find a professional construction team. About us   HEFEI HUMANTEK. CO., LTD. has been dedicated to the research and development and production of tour guide devices for 18 years.

Whether it's international cultural exchanges, overseas tour group services, or cross-border business exhibitions, wireless guide devices are excellent tools for enhancing communication efficiency. For overseas customers, choosing a stable, highly adaptable, and distinctive device not only makes the visitors' experience more comfortable but also showcases their service level. Among numerous brands, the ones with solid technical capabilities and always focusing on scene adaptation and innovation can be considered reliable choices for special features. Their products have passed international certifications such as EU CE and RoHS, and are exported to Europe, Southeast Asia, and the Americas. The usage requirements of different countries can basically be covered.   Yingmi: A Special Benchmark Brand in the Guide Device Industry   Yingmi is a brand under HEFEI HUMANTEK. CO., LTD. It was established in 2007 and has been focusing on the matter of voice guidance and display for many years. Now it is a national high-tech enterprise, a big data enterprise, and an innovative enterprise. Many brands in the industry are busy selling products but don't pay much attention to research and development. However, Yingmi didn't follow this path from the very beginning - it has built a complete service chain from R&D, production, sales, installation, and after-sales service. It has four automated SMT production lines, and all PCBA are produced in-house, all for the purpose of controlling quality from the source.   The features of Yingmi are not only strong in technical capabilities, but more importantly, it truly understands the needs of overseas markets. Since 2009, when it started doing exports, Yingmi has been optimizing products based on feedback from overseas customers. For example, different countries have different voltages, and there are also differences in the typical usage scenarios. Specialized solutions are always customized. For large international events like the International Museum Forum, Yingmi's guiding equipment was used, and it has accumulated a lot of experience in overseas projects. The slogan "Listen to Yingmi to Explore the World" also shows its determination to do global business.   Core Technology Empowerment: Three Key Features of Yingmi's Wireless Guide Devices   For wireless guide devices, whether they are good or not mainly depends on two points: whether the technology is stable and whether it is convenient to use. Yingmi has many core patents and has used these technologies to create its own features, effectively solving various problems encountered by overseas customers when using guide devices.   Feature One: Multi-Positioning Technology Integration, Precise Guidance in All Scenarios   Yingmi did not limit itself to the traditional single positioning method. Instead, it integrated RFID, infrared, and WiFi positioning technologies to ensure that guidance could be precise in any scenario. For example, in places with densely placed exhibits like museums and art galleries, its C7 self-service guided tour system is particularly suitable - it has two modes of automatic sensing and NFC touch sensing. If the distance between the guidance points exceeds 5 meters, automatic sensing can be used, and tourists don't need to touch, they can walk up and automatically play the content; if the exhibits are close together and there is a risk of interference, simply touching the NFC tag card of the guided device can accurately hear the explanation for the corresponding exhibit. The problem of adjacent guidance points interfering with each other has been completely solved.   For open areas like scenic spots and large enterprises for visits, Yingmi's M7C automatic sensing + team guidance system is very suitable. It uses advanced RFID modulation technology, with extremely strong anti-interference ability, and can pre-set multiple signal numbers. Even in large venues with many guidance points, it can withstand them. Moreover, the signal transmitter uses lithium batteries, which need to be replaced only once every 2-3 years, significantly reducing the maintenance costs and making it very convenient to use.   Feature Two: Dual Superiority in Sound Quality and Battery Life, Suitable for Long-Distance Cross-Border Use   When overseas customers choose guide devices, the two things they care about the most are sound quality and battery life. Yingmi achieved both of these through technological breakthroughs. Its team used SOC embedded integrated digital filtering and noise reduction technology in the system to filter out environmental noise and external signal interference, ensuring no loss in audio transmission. Even at a distance of 500 meters or when multiple teams use it simultaneously, the audio quality remains clear, without any noise.   In terms of battery life, Yingmi was designed based on the actual usage habits of overseas customers - such as long-distance exhibitions overseas, multi-day scenic area group tours, where the equipment needs to be powered on for a long time. These scenarios can all be met. The M7C self-service guide machine has a standby time of at least 11 hours, and continuous use for more than 7 hours is no problem; the C7 guide machine has a battery capacity of 800mAh, and it can work continuously for over 10 hours, capable of withstanding all-day high-intensity use. Additionally, the device also has low battery alert, automatically prompting when the battery is running low. The accompanying charging box is also very practical, capable of charging 45 devices at once, and it can be equipped with an ultraviolet disinfection function, providing greater peace of mind when used in overseas public scenarios.   Feature 3: Multilingualism and Customization, Meeting Global Diverse Needs   Considering that most overseas communication is in a multilingual environment, Yingmi has specially made multilingual adaptations. Many of its products support free switching among 8 languages, with clear prompt sounds during the switch, and the previously selected language will be automatically saved, allowing for the previous settings to be directly applied upon startup, without the need for repeated adjustments. Tourists from different countries can use them smoothly. In addition, Yingmi can be customized - such as the startup sound, alarm sound, and low battery alert sound, can all be changed according to customer requirements; even the explanation content can be customized, whether it's the exhibits introduction in a museum or the presentation in an enterprise exhibition hall, it can meet personalized needs.   Scene-based product matrix: Recommended Yingmi characteristic products   Yingmi's product line is comprehensive, including self-service guidance, team guidance, and area-specific guidance, covering various scenarios. There are two products that have particularly good reputations among overseas customers due to their prominent features and wide applicability.   Recommendation 1: C7 Self-service Guide System - Exclusive Feature Solution for Museums and Art Galleries   This is specifically designed for places with dense exhibits, such as museums and art galleries. The biggest highlight is the dual sensing mode, with strong anti-interference capabilities, and there is no need to worry about crosstalk. It can store multiple segments of explanations and supports MP3 format, with particularly clear looping playback sound quality, with a sampling rate up to 44.1k and 128kbps. The device is also compact, with a size of only 82×59×12.5mm and a weight of only 50 grams, making it not heavy to hold in hand or hang around the neck. The accompanying storage box is made of all-aluminum material, with silicone grooves and sponge inside, capable of holding 30-50 devices, convenient for transportation or daily management. Many museums and art galleries in various countries are now using this model, making it particularly suitable for overseas cultural display scenarios.   Recommendation 2: M7C Automatic Sensing + Team Guidance System - All-Scenario All-Function Feature Solution   This is Yingmi's "all-rounder" - it supports three modes of full functionality, speaker function, and sensor function for switching, suitable for various scenarios such as scenic areas, enterprise visits, exhibition receptions, and university training. Its manual explanation transmitter covers the frequency range of 860-870MHz, with an effective distance of up to 180 meters in open areas, and supports 150 channels, even when multiple teams are explaining simultaneously, there will be no interference. The most practical feature is that it can simultaneously activate manual and automatic sensing explanations - the tour guide can give real-time explanations while leading the team, and tourists can trigger automatic explanations when they want to explore on their own, being flexible and convenient, especially suitable for large overseas scenic areas and multinational enterprise exhibition halls.   Full-cycle service guarantee: Yingmi characteristic services adapted to overseas customer needs For overseas customers, the biggest concern when purchasing equipment is the lack of after-sales service - after all, being so far away across the ocean, if problems arise and you can't find anyone to help, it will be troublesome. Yingmi's "9G Full Lifecycle Service" precisely addresses this concern, and this is also its service feature. The pre-sale response is extremely fast; it can accept requirements within 90 seconds and can also send samples for free testing to help customers select the equipment that suits them best; during the middle sale process, on-site inspections of the site can be conducted, and if there are urgent orders, they can be dispatched on the same day; the after-sale service is more worry-free, providing professional installation, free technical support, and lifetime guarantee. There is also a service center for after-sales support in each overseas sales area, which can handle problems promptly.   In addition, Yingmi has established a 7S product quality control system. Every device must pass five inspection stages to ensure that the equipment remains stable and reliable after long-distance transportation and long-term use. Moreover, its products have passed the dual standard detection certifications of China's CMA and CNAS, fully meeting the quality requirements of the overseas market, and customers can use them with peace of mind.   FAQ   Q1: What voltage standards does the Yingmi wireless explainer support? Is it compatible with overseas countries? A1: The default input voltage is 220V. If the voltage in your country is different, we can provide a compatible voltage adapter, and you can use it directly.

Although the body looks small, it is very sturdy. The outer shell is made of wear-resistant and impact-resistant materials. When rented in scenic spots, tourists are bound to bump and scratch it. Even if it is used by dozens of people every day and lasts for one or two years, there will be no obvious scratches on the body, and the structure will not become loose. Moreover, its ear-clip design fits the ears very well, so whether adults or children wear it, it is not likely to fall off, reducing damage caused by drops, and indirectly enhancing durability.   The core components are reliable, and fewer malfunctions mean true durability.   The durability of the guide device depends on the quality of the core components. The i7 uses Yingmi's own-developed SOC embedded digital noise reduction technology. Not only does the sound quality sound clean, but the circuit is also very stable and will not malfunction due to external signal interference. The power supply is also very reassuring, with a PMU safe intelligent lithium battery that not only has a long battery life but also is explosion-proof. It can withstand many charge-discharge cycles without any problems. There is no need to frequently replace the battery, which is both cost-effective and reduces battery damage-related malfunctions.   It is worth mentioning that the signal trigger of the i7 is particularly durable. Yingmi tested the chip for 2 years, choosing high-quality long-life and low-power chips from the industry. It does not require power lines, and a single battery can last for three years. For those overseas remote scenic spots or museums, there is no need to frequently replace the trigger battery, saving a lot of maintenance trouble.   It has strong adaptability and is not afraid of cold, hot, or humid environments.   The environmental differences in different places overseas are huge. Some areas are hot and humid, while others are cold and dry. For guide devices, this is a major test. The i7 has undergone strict high and low temperature and humidity tests before leaving the factory, and can operate stably within the range of -10°C to 45°C. In tropical humid regions like Southeast Asia or places with cold winters in Europe, using the i7 does not require worrying about the device getting damp or having circuit problems.   YingmiL8 Team Guidance System: High-frequency Reception Scenarios L8 is the main product of the Yingmi team's presentation series, mainly used for enterprise receptions, government meetings, and study tour teams. Its durability is mainly reflected in "stable power supply and strong anti-interference ability".   The design is extremely simple, with fewer failure points and greater durability.   The design of L8 is particularly simple. The functions of the transmitter and receiver are clearly divided, and there are few buttons. The button quality is particularly good, and even if pressed many times, it won't break, reducing the occurrence of faults caused by operational errors or button damage. The receiver supports both dry battery power supply and can be used with a charging kit, which is very flexible. If the power supply in some overseas regions is unstable, using dry batteries can avoid charging problems; if it is used in a fixed location for a long time, a charging kit should be used, and repeated use is more cost-effective.   The body is an integrated design, with sealed interfaces, which can prevent dust and moisture from entering the body and causing short circuits. Even when conducting receptions outdoors or visiting construction sites or factories, dust and moisture are not likely to enter the body and cause short circuits. Its kit includes 1 transmitter, 10 receivers, and 1 10-position charging kit. The charging kit is plug-in type, charging is stable, and it is very durable, without problems of poor charging contact.   The anti-interference ability is fully enhanced, and it remains stable even when used for a long time.   The team presentation is most afraid of interference and disconnections when multiple teams use it simultaneously. Even if the equipment is very durable, if such problems occur frequently, it cannot be used. L8 uses digital secondary frequency anti-interference technology, with a very narrow channel bandwidth, supporting simultaneous use by multiple teams without interference. Even during overseas large-scale exhibitions or peak periods in scenic areas, with dozens or hundreds of teams using it together, L8 can still transmit sound stably without dropping connections.   Moreover, its wireless amplification technology has excellent wall-penetrating effect, a long transmission distance, and also comes with AI lossless original sound processing. Not only is the sound quality clear, but the signal stability also does not decline over the long term. Many overseas enterprises have reported that L8 has been used for several years and the transmission effect is still as good as new, with rare signal failures.   The common advantages of i7 and L8: dual guarantees from technology and after-sales service   In addition to their respective highlights, i7 and L8 also share Yingmi's core durable technology and after-sales support. Technically, both use Yingmi's independent patents, with stable circuit design and reliable core components; in terms of quality control, they have undergone strict environmental tests and lifespan tests, meeting EU environmental protection and safety standards; in terms of after-sales service, Yingmi has the "9G full life cycle service", and overseas customers can contact the after-sales team by email or phone if they encounter problems, and technicians will first remotely diagnose; if repair is needed, it can be sent to the designated overseas service point or the domestic headquarters, and if there are quality problems within three months, it can be replaced directly, and within one year, free maintenance is provided, greatly reducing the risks in the later use.   FAQ   Q1: Can the i7 and L8 devices adapt to the hot and humid tropical environment? A1: No problem! Both of these devices have undergone rigorous high-low temperature and humidity tests before leaving the factory. They can operate stably within the range of -10℃ to 45℃. The body interfaces are tightly sealed, providing dust and moisture protection. These devices have been used in tropical regions like Laos and Malaysia for several years, and the failure rate is very low.   Q2: How long does the battery of the device last? Is it convenient to replace the battery later? A2: The lithium battery of the i7 can be cycled for hundreds of times under normal use, with a lifespan of approximately 2-3 years. The L8 receiver can use dry batteries or rechargeable batteries. The lifespan of the rechargeable battery is similar to that of the i7. It is very convenient to replace the battery later. No professional tools are needed. Contact Yingmi's after-sales service to obtain the compatible battery and you can replace it yourself.   Q3: The voltage in foreign countries is different from that in China. Will the device be damaged? A3: Absolutely not! The charging equipment of the i7 and L8 supports a wide voltage range of 100V-240V, covering the voltage standards of most countries in the world. Once in the local area, just change the local specification plug and it can be used directly. No additional transformers are needed.   Q4: Is the device prone to failure under high-frequency use? Is the repair convenient? A4: Not likely! Both devices have undergone 5 strict tests and meet the 7S quality control standards. The failure rate is very low under high-frequency use. Yingmi has a mature after-sales network overseas. If there are any problems, you can contact the after-sales service by email or phone. The technicians will first conduct remote diagnosis. If repair by mail is needed, it will be repaired within 10 working days after being sent to the designated service point. If the time limit is exceeded, you will be sent a spare device.   Q5: If multiple teams use it simultaneously, will the signal interference affect the stability of the device? A5: No! Both devices use digital anti-interference technology. The L8 supports 200 channels for selection. The i7 uses high-precision positioning sensing technology. Even if multiple teams use it closely together, there will be no interference, no disconnection, and it can operate stably even during peak periods. About us   HEFEI HUMANTEK.

When foreign customers purchase wireless audio guide devices, "a reasonable design" is much more important than "having a lot of functions". Many brands seem to have fancy parameters, but in reality, they all have flaws: wearing for a long time causes ear pain, when multiple teams use it, there is crosstalk, the screen is hard to see in the strong sunlight outdoors, and switching to a minority language is troublesome. These problems all arise because the design does not match the actual usage scenarios. After working in this industry for a long time, based on feedback from global customers, the key to truly reliable brands is four points: wearing comfortably, adapting to the scenarios, attentive details, and global compliance. Yingmi is a representative of such brands.   To determine if the design is reasonable, it is enough to look at these three points   Don't just judge the quality of the audio guide device design based on a single indicator. It should be viewed from the entire process of user use. These three points are the ones that foreign customers should pay the most attention to when purchasing.   The first point: Wear comfortably, different people won't get tired after wearing for a long time   The audio guide device is a "thing that is worn on the body for a long time", whether it's tourists in scenic spots or guests at exhibitions, how comfortable they wear it directly affects the experience. Unreliable products are either too heavy or uncomfortable to wear. After wearing for half an hour, ears will hurt intolerably. Reliable ergonomic design focuses on three points: light, comfortable wearing method, and suitable body size.   The second point: Adapt to scenarios, solve core problems in different environments   Museums, scenic spots, large conferences, factory visits, etc., there are huge differences in requirements for different scenarios: museums need precise explanations without triggering, scenic spots need strong anti-interference, conferences need multilingual synchronization, factories need to be resistant to drops and wear and tear. Brands with reasonable design will specifically design products for different scenarios, not relying on one product to cover all scenarios.   The third point: Attention to details, no matter which country's users, it should be easy to use   Foreign customers come from different countries, they have higher requirements for simple operation and clear display. Good detail design should be able to "be used without referring to the manual", such as one-click switching to multiple languages, larger buttons to accommodate different hand sizes, a full charge lasting a whole day, and convenient storage of accessories.   Why is Yingmi's design reliable? Details are considered globally   The advantage of Yingmi in designing products is that it takes these four points into account, not sacrificing one for the other. The design details of several core products of Yingmi precisely hit the core needs of foreign customers.   Comfortable to wear: Light and fitting, suitable for any body type   Yingmi has done a great job in the "comfortable to wear" aspect. The core is light and fitting to the ears. For example, its classic R8 ear-mounted audio guide device uses an ergonomic non-in-the-ear design, which neither causes discomfort like in-ear designs nor is it messy and hygienic. No matter what ear shape, it can be worn. The body weighs only 16 grams, about the same as two coins, and wearing it for a whole day doesn't feel anything.   Even the transmitter for the audio guide device for interpreters is very thoughtful: 41 millimeters wide, 20 millimeters thick, very small, weighing only 27 grams. It can be casually placed on the collar or in the pocket without taking up space or affecting walking and raising actions. This lightweight design is extremely friendly for scenic spot interpreters and exhibition guides who need to move around all day.   Adapt to scenarios: One product solves the pain points of one scenario   Yingmi does not create "universal products", but designs specifically for different scenarios, which is the key to its reliable design.   For example, museums and art galleries need precise explanations, so it has launched the 007B automatic sensing audio guide device system, using RFID modulation technology and digital on-demand mode, perfectly solving the problem of "triggering when the exhibits are close". When visitors carry the equipment and walk to the exhibits, it starts to explain automatically, stops when they leave, and won't trigger even if the two explanation points are close; The screen is a 2.8-inch true-color display. Whether indoors or in the strong sunlight outdoors, it can be clearly seen. Even elderly tourists can easily understand the language and the progress being discussed.   In complex environments such as factories or outdoor scenic spots, the shell of Yingmi products is made of high-strength materials. It has passed the drop test and won't easily break even if dropped on the ground. The battery inside uses PMU safe and intelligent management technology, which can work stably in extreme environments such as high temperatures and low temperatures. The products have been tested in places like the Xiangkun Temple in Vientiane, Laos, and the dry and dusty areas of Karamay, and there have been no problems.   Detailed design: Users from any country can use it smoothly   Yingmi's detailed design always considers "users' convenience". It is especially suitable for foreign customers. For example, in terms of languages, all product series can support multiple languages. The 007B guide machine can store up to eight segments of explanations by default. If there is a need for a minority language, it can be added with just one click. The battery of the 007B guide machine is 850mAh, and it can last for more than 10 hours after one charge, which is sufficient for use throughout the day in scenic spots. The charging box that comes with it can charge up to 32 devices at the same time and can protect the battery, extending its lifespan. It is suitable for customers who need to make bulk purchases. There is also a portable one-charging-ten-use USB charger that supports global voltage and is convenient to take on trips.   In addition, the dedicated storage box of Yingmi is made of all-aluminum material, with silicone grooves inside. The 32 devices can be precisely placed inside, and they are not easily damaged during transportation. There is also a place reserved for accessories. For scenic spots and exhibition customers who often move equipment, it really saves a lot of trouble.   Global compliance: Considering different country requirements from the beginning   When designing products, Yingmi considered global compliance issues from the very beginning to avoid customers being unable to pass customs after purchasing. All products have passed EU CE, RoHS environmental certification, as well as China CMA and CNAS dual testing certification. The body material of the products complies with global environmental protection standards. The charging equipment is designed with a wide voltage, which can be used in any country's voltage. No additional transformers are needed. The product manual and body identification support multiple languages, so users from any country can understand. Because of this, Yingmi has never encountered a situation where it couldn't clear customs due to compliance issues during its many years of foreign trade.   Covering mainstream scenarios, the design is really user-friendly   Based on the most popular models purchased by foreign customers, the design rationality of these two products has been tested in the global market and can be used in most mainstream scenarios.   Recommendation 1: 007B Automatic Sensing Interpretation System - The first choice for museums and scenic spots   This is Yingmi's export bestseller. The core design is "precise sensing + convenient to use". Besides the mentioned anti-interference and clear screen, it also supports two modes: point selection and automatic sensing. Tourists can listen as they go, and they can precisely select a certain exhibit by inputting the number. The body weighs only 100 grams and is designed as a neck-worn style. It is comfortable for users of any body type, even if they are wearing a backpack, and it won't get stuck. Now, high-end venues such as the International Museum Forum and the Guizhou Geological Museum are using it, and it has also been sold to many countries in Europe and Southeast Asia.   Recommendation 2: R8 Ear-Pendant Team Interpreter - Essential for meetings and corporate visits   This is specifically designed for team reception. The non-in-the-ear ear pendant is comfortable and hygienic, and it is reassuring for multiple batches of customers to use it in rotation. It uses SOC embedded integrated digital noise reduction technology, which can filter environmental noise. Even in noisy factory workshops or exhibition sites, the sound quality is still clear. It can also simultaneously transmit multiple languages and store multiple segments of explanations. It is suitable for multinational enterprise visits and international conferences.   FAQ   Q1: Can the Yingmi speaker be customized? For example, can the brand logo be printed or can additional minority languages be added? A1: Of course! Both the body and the storage box can be printed with the brand logo. At least 50 units need to be ordered; for languages, in addition to the default eight languages, any minority language can be added. The maximum number of explanation phrases that can be stored is up to multiple segments. The customization period is 7 to 15 days, which can precisely match the brand promotion and local usage needs.   Q2: Can the screen be clearly seen in the strong sunlight outdoors? Is a single charge sufficient for one day? A2: Absolutely! The screen is a high-brightness true-color screen. Even without covering it, it can be clearly seen. The battery life is reliable. Mainstream products can last for 10 to 16 hours after a single charge. It is sufficient for use in scenic spots and exhibitions throughout the day. The accompanying charging equipment can also quickly replenish the charge.   Q3: Will there be interference when multiple teams use it simultaneously? How many teams can it support at most? A3: No interference! The digital secondary frequency anti-interference technology is used, and the channel bandwidth is small. It can support up to 20 teams to use simultaneously. Each team can use their own channel. Even in small exhibition halls or crowded scenic areas, it is very stable.   Q4: Can the product pass the EU and American certifications? Are all the customs clearance documents complete? A4: Both can pass! All products have passed EU CE and RoHS certifications, and also comply with the safety and environmental protection standards of the Americas. The detection reports and certification certificates required for customs clearance will all be prepared in advance. Yingmi ships products globally all year round and has never been delayed in customs clearance due to compliance issues.   Q5: Can people with different ear shapes and body types wear it? For example, children or people with large body types? A5: They can all wear it! The ear-hanging type can be adjusted. Whether it's a child or an adult with a different ear shape, it is suitable. The neck-hanging type's hanging rope can be adjusted to any length. The body size is also made according to ergonomics, so it won't be tight or uncomfortable for any body type.
