Quality Tour Guide Audio System & Wireless Tour Guide System Factory

Nowadays, the demand for cultural tourism and business receptions worldwide is increasing, and various brands are emerging. However, for foreign customers, they don't need to look at too many flashy advertisements to choose a brand. The core points are: one is that the equipment is reliable and stable, and the other is that it can adapt to the usage standards and scenarios of their own countries. Yingmi stands out precisely because of its 18 years of technical accumulation and precise grasp of the needs of foreign customers. Especially its i7 self-service interactive guide device almost covers all the core needs of foreign customers. Its reputation has always been stable.   To determine if a wireless guide device brand is competitive, foreign customers only look at these 4 hard indicators.   When many foreign customers choose a brand, they are often misled by superficial parameters. In fact, whether a wireless guide device brand is competitive mainly depends on whether it can solve the problems in actual use. Based on the feedback from global customers over the years, compliance certification, scene adaptation, technical strength, and after-sales guarantee are the four points that foreign customers value the most, and they are also the core to distinguish between high-quality brands and small workshops.   Hard Indicator 1: Compliance certification is the bottom line. Only when the frequency band is compatible can it be used safely.   Foreign requirements for wireless electronic devices are much stricter than those in China, especially regarding frequency bands and safety standards. There can be no mistakes. Many small brands try to save time and costs by not doing local compliance certification and not adapting to local frequency bands. As a result, when the products are shipped abroad, they either fail to pass customs and are detained, or experience frequent frequency band interference when used, causing foreign customers to waste money in vain. Truly competitive brands have already made global compliance arrangements in advance to ensure that the products can be legally and stably used in any country.   Hard Indicator 2: Comprehensive scene adaptation is necessary for the brand to go far   The usage scenarios of wireless guide devices are very diverse, ranging from museums and historical sites to enterprise exhibition halls and outdoor scenic spots. Foreign customers do not want a device that can only be used in one place; instead, they want a solution that can meet the needs of multiple scenarios at once - such as self-service sensing in exhibition halls, no need for manual supervision; strong anti-interference in outdoor scenic spots, not afraid of wind and sun exposure; multi-language support in enterprise receptions, able to handle international customers. The more scenarios a brand can cover, the more it can impress foreign customers, and the stronger its market competitiveness will be.   Hard Indicator 3: Strong technology is necessary to ensure the usage experience   The clarity of sound quality, the stability of the signal, and the duration of battery life - these are the most intuitive usage experiences for customers, all relying on technology support. For example, in noisy scenic spots, can it filter out noise; when multiple teams use it simultaneously, will there be crosstalk; can it last a whole day when on tour or in an exhibition hall? These details are what foreign customers focus on. Those small brands without much technical accumulation often fail in these key areas, and once they use it, they have no repeat customers, unable to form long-term competitiveness.   Hard Indicator 4: Complete after-sales service is necessary to dispel cross-border concerns   For foreign customers, after-sales is really very important. If the equipment fails to work properly in the foreign country, can it be repaired in time; when encountering problems in operation, can someone be found to guide; after batch purchases, can customized services be provided? These all directly affect the customer's choice. Competent brands will build a global after-sales system to ensure that foreign customers don't have to worry about after-sales, buying with peace of mind and using with confidence. Yingmi i7: Mastering customer pain points, pulling full competitiveness with details   Yingmi's success in the global market is not through advertising, but through the actual performance of the i7 self-service interactive guide device. This device precisely understands all the pain points of foreign customers, and every detail design is in line with actual usage needs. It not only improves customer experience but also makes Yingmi's brand competitiveness stronger and stronger.   1. Full compliance + adjustable frequency band, no trouble in cross-border use   Foreign customers choose i7 because they are most assured of its compliance and frequency band compatibility. This device has passed the EU CE and RoHS certifications and also supports fine-tuning according to different national frequency standards.

Moreover, it uses the Type-C fast charging interface, which is compatible with global voltages ranging from 110V to 220V, and there is no need to specially purchase conversion adapters. Any ordinary adapter can be used for charging, completely solving the voltage problem for cross-border use.     2.Automatic sensing + multilingual support, suitable for all scenarios   The most practical function of i7 is self-sensing - when combined with the sensing tag, when visitors approach the corresponding exhibit, the device will automatically trigger the explanation, and when they leave, it will automatically stop. There is no need for manual operation or following an on-site guide. This design is particularly suitable for museums, historical sites, and corporate exhibition halls, saving costs on human explanations and allowing visitors to visit at their own pace, providing a better immersive experience.   Most foreign customers have the need for multiple languages, and i7 supports customizing 8 mainstream language explanations. Whether it is receiving tourists from small language-speaking countries or holding international business exhibitions, it can easily handle them. Not only that, its anti-interference ability is also very strong. Even if multiple teams use it simultaneously in a small exhibition hall, there will be no frequency interference or noise issues. It is completely fine to use it in popular tourist attractions and large exhibition halls.   3.Hardcore technology support, convenient and durable to use   Sound quality and battery life are the core of the wireless explainer device. i7 has done a good job in both aspects. It is equipped with digital noise reduction technology, even in a noisy environment of 80 decibels or above, it can filter out the surrounding noise and transmit the explanation clearly to the visitors' ears, whether it is for elders or those with sensitive hearing, they can hear it clearly. The battery life is also reliable, with a single charge being able to last for 11 hours, fully covering the open hours of the exhibition hall; if there is a temporary power outage, the Type-C fast charging can quickly replenish the power, and there is no need to worry about interruption in use.   Considering the use scenarios in outdoor scenic areas, i7 has specially optimized its durability, capable of withstanding outdoor sun exposure and rain, with a durable and shock-resistant body material, even for large-scale use and frequent distribution, there is no need to worry about damage, which can help foreign customers save a lot on equipment wear and tear costs.   4.Convenient management design, reducing batch usage costs   Many foreign customers purchase equipment in large quantities, and the management is very troublesome. i7 precisely solves this pain point. It is equipped with a dedicated charging and storage integrated box that can hold dozens of devices at once and also charge them simultaneously. This can not only save storage space but also manage the battery levels of each device uniformly, without worrying about missing charging.

It can be used for exhibition reception, scenic area guidance, and enterprise exhibition visits. Whether visitors wear it for a long time or staff carry and distribute it in batches, portability directly affects the usage experience and work efficiency. Choose a portable guide device. Don't just focus on the small appearance; you also need to consider the weight, size, wearing method, and whether it's convenient for storage. Yingmi, which has been in this industry for 18 years, has the M7 neck-mounted automatic sensing guide device. It precisely meets all the customers' demands for "easy portability". It is the preferred choice for many customers.   To select an easy-to-carry wireless guide device, just consider these 4 points.   For customers, "easy portability" is not just about being "small"; it also needs to consider that the device is comfortable for visitors to wear for 1 to 3 hours, saves space for batch storage and transportation, and is not prone to damage during long-term use. This is the true portability. Look at these 4 key dimensions, and it's easier to avoid mistakes when making a selection.   Dimension 1: Light weight, not heavy to wear for a long time   For visitors in exhibition halls and scenic areas, they often wear the guide device for 1 to 3 hours. If the device is too heavy, the neck and ears can easily become sore, and it may even affect the visiting mood. Truly portable guide devices usually have a host weight controlled within 50g, about the same as an ordinary egg. Worn on the body, it hardly feels anything, and even if used for a long time, there won't be a burden.   Dimension 2: Small size, no space occupation, easy to store   Most customers purchase in batches for exhibitions and scenic area distribution. If the device is too large, not only does it increase transportation and storage costs, but it also makes on-site management troublesome. Portable devices need to be thin and compact, so they can be easily placed in storage boxes and won't be obtrusive or troublesome for visitors to carry with them, even when they are on the go.   Dimension 3: Easy to wear, suitable for all types of people   The age and body type of visitors vary greatly. Portable wearing methods should not require complex adjustments. Just take it and wear it, and it should be suitable for different clothing styles - whether it's formal, casual, or outdoor wear. The most common types are neck-mounted and ear-mounted. The neck-mounted type is more suitable for long-term wear, as it doesn't need to be clipped onto clothes and doesn't squeeze the ears. It has better adaptability.   Dimension 4: Convenient storage and compatible with batch storage   Most purchases require long-distance transportation and batch storage. The accompanying storage equipment is particularly crucial. Easy-to-carry guide devices need a dedicated storage box to protect the device from damage and wear during transportation and to facilitate orderly storage and quick counting. It saves space and management costs.   18 years of Yingmi's deep focus: M7, the preferred portable guide device for customers   Since its establishment in 2007, Yingmi has been dedicated to making wireless guide devices for 18 years.

Whether it's in museums, exhibitions, scenic spots, or enterprises, what everyone cares about is the same: no interference, no power failure, stable signal, and the ability to adapt to various complex scenarios. No need for repeated adjustments, and it truly allows people to relax. There are many brands of narrator devices on the market, and many of them work well in a single environment, but when it comes to situations with multiple teams simultaneously receiving visitors, numerous electronic devices, or large open spaces, they tend to fail - signal loss, poor sound quality, insufficient battery life, which seriously affects the reception. After years of market testing, the L5 wireless narrator device under Yingmi has become the preferred choice for customers for its stable performance. This is because this brand has been deeply rooted in the industry for 18 years, providing solid technical support and strict quality control.   Selecting a wireless narrator device: The stability can be determined by these 4 key indicators   For customers, the "stability" of a wireless narrator device is not just about "no disconnection". It must be able to adapt to different signal environments in various countries, be able to withstand a full day of reception, not interfere with each other when multiple teams are using it, and be convenient for batch management. After working in this industry for so long, everyone knows that the key to judging whether a narrator device is stable lies in these 4 hard indicators. And the L5 model has achieved industry-leading levels in all these aspects.   Hard Indicator 1: Interference Resistance - No interference, no noise in various scenarios   In situations with multiple teams receiving visitors simultaneously, there are often multiple electronic devices. Interference from mobile phone signals, broadcast signals, and other electronic devices can easily cause interference and noise in the narrator device, completely ruining the good listening experience. Therefore, a reliable wireless narrator device must have strong interference resistance to be able to handle such complex scenarios.   Hard Indicator 2: Battery Life - No power failure during the entire reception period, convenient batch charging   In museums, scenic spots, and exhibitions, the reception time is usually 8 to 10 hours, and some large events even last for several consecutive days. If the narrator device runs out of power halfway, the reception will be interrupted, which is not only troublesome but also affects the reputation. In addition, most customers need to manage the equipment in batches, so whether it is convenient for batch charging has also become an important factor affecting stability.   Hard Indicator 3: Signal Transmission - Full coverage in open or complex environments, no blind spots   Scenic spots are usually more open, while museums and exhibitions are either multi-level exhibition halls or large areas. How far the narrator device can transmit signals and whether it can cover the entire area directly determines its stability. A good narrator device not only needs to be able to transmit signals stably over long distances but also needs to avoid signal weakening when passing through walls or being obstructed.   Hard Indicator 4: Quality Control and Adaptability - Meets standards, no malfunctions during long-term use   When customers purchase narrator devices, they usually need to use them in batches for a long time, so the quality control of the equipment must be perfect, and it cannot frequently malfunction. Moreover, the signal frequency standards of different countries are different, and the narrator device must be able to adapt to the local frequency and pass relevant international certifications to be able to use stably for a long time.   18 years of industry accumulation: Yingmi's technical strength supports the stability of L5   For a device to be stable, it cannot be achieved without the long-term investment and deep focus of the brand. Yingmi has been dedicated to the field of narrator display since its establishment in 2007 and has been fully involved in the entire chain of research, production, and sales of narrator devices for 18 years. It has 4 automated SMT production lines, from the core chips to the final assembly, all are controlled by itself. Unlike some brands that rely on outsourcing production, the quality control is fundamentally unsecured and prone to problems.   As a national-level high-tech enterprise, Yingmi has many core patent technologies and has already started foreign trade business. It has passed EU CE and RoHS international certifications and is familiar with the signal frequency standards of different countries. If overseas customers have any requirements, they can also assist in fine-tuning the equipment frequency to ensure stable operation in the local area.

Interference from external electronic devices such as mobile phones and broadcasts can be largely blocked. Moreover, it innovatively uses a reliable zero-delay radio receiving front-end, combined with digital audio processing back-end technology, ensuring no delay in signal reception. Even if several teams are explaining simultaneously in the same area, they can operate independently through multiple channels, each team using their own exclusive channel without interference or noise, perfectly solving the pain points of parallel reception by multiple teams overseas.   Battery life worry-free: No power outage throughout the day, batch charging is more convenient   L5 is equipped with high-performance polymer lithium batteries and uses PMU safe intelligent power management technology, which is both safe and environmentally friendly, and has excellent battery life. Once the transmitter is charged, it can operate for more than 30 hours, and the receiver can operate for more than 35 hours, fully meeting the 8 to 10-hour reception needs of the venue throughout the day, without frequent charging interruptions to the reception process. Signal stability: 150-meter coverage, no dead spots in any venue   The signal transmission distance of L5 can reach 150 meters. Whether it is an open scenic spot square, or multi-story museums or enterprise workshops, the signal can be fully covered, without the problem of audio loss or deterioration when visitors move a little further. Moreover, it uses digital audio lossless transmission technology, even with walls or obstacles, the sound quality can be maintained clearly, ensuring that the explanation content can be accurately delivered to the visitors' ears.   Another very practical design is that L5 has channel memory function. When the receiver is turned on, it will automatically match the channel it was on when it was turned off last time, without the need for repeated manual adjustment, reducing the faults caused by operational errors and making it more stable and convenient to use.

As a result, the equipment they buy seems to be highly equipped but completely fails to fit the tour guiding scenarios. Instead, it causes more problems. The three most common pitfalls for tour guiding are to avoid these to select a truly useful product.   Severe interference, chaos when multiple teams guide simultaneously   Popular scenic spots and exhibition halls often have multiple tour guides guiding at the same time, which is the most common scenario for tour guiding. Many cheap guide devices have weak anti-interference capabilities. When multiple teams use them simultaneously, interference and lag occur. The tour guide's explanation is disturbed by the voices of other teams, making it difficult for tourists to understand. This not only affects the tour guiding experience but also reduces the professionalism of the tour guide. What's worse, some guide devices have complicated channel adjustment, and when encountering interference, the debugging process is time-consuming and laborious, seriously delaying the tour guiding rhythm.   Heavy equipment, exhausting tour guides and tourists   Tour guides often need to guide for 8-10 hours a day, and tourists also need to wear the guide device throughout the visit. If the equipment is too heavy, tour guides will have a heavy burden when carrying the transmitter and distributing the receivers, and tourists will also experience ear pain after wearing it for a day. Some even will directly remove the guide device, resulting in a significant reduction in the guiding effect. Especially for ear-hanging guide devices, if the design is unreasonable, they are not only heavy but also prone to slipping. They need to be repeatedly adjusted, which is very inconvenient.   Complicated batch storage, delaying tour guiding efficiency   For tour guiding, most tour guides need to receive dozens of tourists. Batch carrying, distributing, and storing guide devices are daily tasks. Many audio guide devices do not have matching storage and charging equipment. When carrying them in batches, they need to prepare separate boxes. When distributing, they need to pair channels one by one. When storing, they need to charge each device one by one. This is time-consuming and laborious. Even worse, the storage equipment does not have shock protection. During tour guiding or outdoor transportation, the equipment is prone to damage, affecting subsequent use.   L7 Team Guide Device: Tailored for Tour Guiding, Every Design Hits the Mark   Yingmi's L7 team guide device is a product optimized based on thousands of tour guiding scenarios. It precisely avoids the above three pitfalls and integrates "practicality, convenience, and stability" throughout. Whether it is multiple teams guiding simultaneously or long-term wearing, it can easily handle and perfectly adapt to the needs of tour guiding. 1. Strong anti-interference + multiple channels, no interference when multiple teams guide simultaneously   For the pain point of multiple teams guiding simultaneously, L7 adopts the UHF 663-694 MHz ultra-high frequency band design, combined with innovative digital audio processing backend technology. The anti-interference capability is significantly improved, effectively isolating external signals such as mobile phones and radios from interfering, and avoiding interference problems when multiple teams use it. What's more, L7 is equipped with a rich range of adjustable channels. The transmitter has 150 independent adjustable channels, and the receiver supports 102 adjustable channels. When multiple teams use it simultaneously, only assign each team an exclusive channel, and one-click matching can be achieved without complex debugging, enabling independent explanations and no interference. In addition, L7 adopts a built-in antenna design, which not only avoids the inconvenience of carrying and placing external antennas, but also further improves the stability of the signal. In an unobstructed environment, the signal transmission distance of L7 can reach up to 100 meters. Even when the tour guide is leading the group in the front and the tourists are lagging behind within a reasonable range, they can clearly hear the explanation without any lag or disconnection.   2.Lightweight design, no burden for long-term use, more convenient distribution   In terms of lightweight design, L7 fully meets the long-term usage needs of tour guides and tourists. The receiver weighs only 16 grams, not much heavier than a coin. It adopts an ear-hook design that does not go into the ear, and there is no distinction between left and right ears. When the tour guide distributes it, there is no need to specifically distinguish, and when the tourists wear it, it fits the contour of the ear without pressing the ear canal. Even after wearing it for a whole day, there will be no soreness, greatly enhancing the tourists' willingness to use.   The tour guide's transmitting device weighs only 48 grams and is small in size. It can be easily hung on the waist or placed in the pocket, without adding any extra burden. At the same time, the transmitting device is equipped with a direct-insert or headband microphone. The tour guide can choose according to their own usage habits. The input gain of the microphone can be adjusted, and it can clearly transmit whether it is a loud explanation or a soft introduction, adapting to different scenarios of explanation needs. 3.Batch storage and charging integrated, convenient for group distribution   For the storage and distribution needs of tour guides in batch group tours, L7 is equipped with a dedicated contact-type charging storage box. This completely solves the problems of batch carrying, charging, and storage. This storage box adopts a metal shell design, which is safe and has no fire hazard. It is equipped with EVA shock-absorbing cotton and independent slots. One box can simultaneously store and charge 50 devices. It avoids damage to the devices due to collisions and realizes batch charging without having to plug and unplug the charging cables one by one.   The size of the storage box is 47 × 35 × 15 cm, and the weight is only 5 kg. It is lightweight and easy to carry. When tour guides take groups across countries or transport by vehicle, it will not add any extra burden. It can also be equipped with an ultraviolet disinfection function. After batch disinfection, it can be distributed to tourists, which is more hygienic, especially suitable for tourists who pay attention to hygiene details. At the same time, the storage box adopts an intelligent charging management mode. It can fully charge 50 devices in 2.5 hours, and charging once at night can fully meet the needs of the next day's group tour.   FAQ:   Q1: Is the signal transmission distance of L7 sufficient? Is it enough for group tours in large scenic areas? A1: It is completely sufficient. The communication distance of L7 is ≤ 100 meters (in an unobstructed environment), and the actual test shows that in large scenic areas, exhibition halls, etc., the signal is stable without lag.   Q2: Can the storage box of L7 be carried on the plane? Is it convenient for batch transportation? A2: It can be carried on the plane. The 50-contact-type charging storage box of L7 is 47 × 35 × 15 cm in size and weighs only 5 kg. It meets the standards for air transportation and can be carried as a carry-on luggage directly or batch-traded.   Q3: When multiple teams use it simultaneously, is the channel adjustment complex? Is there any interference? A3: The channel adjustment is simple, and there will be no interference. L7's transmitting device has 150 adjustable channels, and the receiving device has 102 adjustable channels. When multiple teams are using it simultaneously, only one exclusive channel needs to be assigned to each team. The tour guide can adjust it through the LCD display of the transmitting device with one click, and the operation is simple and easy to understand. Combined with the UHF high-frequency band anti-interference design, multiple teams using it simultaneously can also achieve independent explanations without interference.

When foreign customers are making a purchase, they often fall into the misconception that "the lighter, the better". However, this is not the case. A truly portable wireless tour guide system needs to balance four core aspects: weight, size, wearing method, and storage convenience, and also be adaptable to different usage scenarios - for instance, tour guides in scenic spots need to wear them for long periods, enterprises need to carry them in bulk for reception, and museums require them to be lightweight and not affect the visiting experience. Only by meeting these requirements can it truly be called "easy to carry".   4 core criteria for foreign customers to select portable wireless tour guide systems: Avoid purchasing pitfalls   1. Weight: Not the lighter, the better, but "no burden" is appropriate   For portability, weight is the foundation, but it's not the case that the lighter, the better. Many brands sacrifice the product's sound quality and battery life in pursuit of extreme lightness, even reducing the thickness of the casing, which leads to easy damage of the device. Foreign customers often need to use the tour guide system for long periods, such as tour guides leading groups for 8-10 hours a day, and tour guides need to repeatedly wear and store the devices when receiving multiple groups. At this time, the weight of the device is best controlled between 15-25 grams - this weight range can ensure the stability and durability of the device, and also allow for long-term wear without pressure, and it won't cause a significant burden when put in a pocket or worn on the ear.   It's worth noting that foreign customers often need to carry the tour guide systems in bulk, such as preparing devices for dozens of tourists at once in a scenic spot. At this time, the weight difference of a single device will directly affect the overall carrying burden. Therefore, in addition to the weight of a single device, the convenience of bulk storage should also be considered, a point often overlooked by many customers.   2.Wearing method: Adapt to scenarios, and being comfortable for long-term wear is more important   The wearing method of a wireless tour guide system directly determines the convenience of carrying and using. Currently, the common wearing methods on the market include ear-hook type, chest-hook type, and in-ear type. Among them, the ear-hook type is the most suitable for multiple scenarios abroad and is easy to carry - the ear-hook type does not require holding, does not occupy hand space, can be directly hung on the ear when wearing, and can be easily stored after removal, unlike the chest-hook type which requires a lanyard, or the in-ear type which is prone to loss or hygiene risks.   For foreign customers, the ear-hook type tour guide system also needs to meet two details: one is that it is not left or right ear specific, making it convenient for quick wearing and distribution; the other is that it adopts ergonomic design, fitting different ear shapes to avoid ear pain after long-term wear. Especially for tourists in foreign museums and scenic spots, who have different skin colors and ear shapes, a universal ear-hook design can fit more people and improve the user experience.   3.Convenient storage: No pressure when carrying in bulk, suitable for outdoor/exhibition hall scenarios   When foreign customers purchase tour guide systems, they often need to use them in bulk, so the convenience of storage is crucial. Many brands' tour guide systems, although lightweight individually, do not come with dedicated storage and charging equipment. When carrying them in bulk, separate boxes need to be prepared, which is not only cumbersome but also prone to device damage. A truly portable tour guide system must be equipped with a dedicated storage and charging integrated box, which can achieve bulk charging, facilitate storage and transportation, and even be directly taken on planes and trains without additional packaging.   In addition, the design of the storage box should also meet the needs of foreign customers, such as using an aluminum alloy shell, which is lightweight and durable, and can withstand collisions during outdoor transportation; having independent slots and shock-absorbing foam inside to ensure each device is stably placed and reduce vibration damage; and having a dedicated area for accessories to store charging cables, microphones, etc., to avoid loss.   4.Long battery life: Reduce charging frequency, avoid carrying charging equipment   Battery life, although not directly affecting "portability", indirectly determines the convenience of carrying. If the battery life of the audio guide is short, customers will need to charge it frequently, which means they have to carry charging equipment, increasing the burden of carrying. Especially in outdoor scenarios, where there is no power supply, insufficient battery life will directly affect usage. Therefore, a portable audio guide should have a battery life of at least 8 hours to meet the usage needs for a whole day, and it should also support batch fast charging to save charging time.   Yingmi 2 Portable Products: Adapted for Multiple Overseas Scenarios, 18 Years of Quality Accumulation   Yingmi has been deeply involved in the wireless audio guide industry for 18 years.
