Last year, a provincial museum in the north was in a dilemma. With an increasing number of international tourists, the museum’s existing tour guide devices only supported 3 languages. Small language speakers had to rely on manual translation, which was not only costly but also often unable to find suitable personnel. What was more frustrating was that the signals in adjacent display cases often interfered with each other, and tourists standing in front of the bronze artifact display case would hear the explanations from the ceramic display case instead. Complaints piled up like a mountain. Later, they tried using the M7 neck-mounted self-service audio tour device from Yingmi, and within a few days, they sorted out the problem – the M7 itself comes with 8 common languages. If small language speakers are needed, it can be customized within 3 to 7 working days, allowing international tourists to choose the language themselves without waiting for translation. Moreover, it uses digital encoding and spread spectrum technology, so the signals in adjacent exhibition areas do not interfere with each other, and the accuracy of the explanations can reach 99.9%. After this incident spread, many peers realized: when choosing a audio guide device, finding the right manufacturer can be much more effective than simply choosing a more expensive one.
I. The most annoying issues when choosing a wireless audio guide device
When many customers start to choose a audio guide device, they tend to focus on the price, but after using it, they realize that there are many troubles. The common annoying issues are actually just a few: First, the signal is unreliable. The signals of adjacent attractions and display cases interfere with each other, and the explanations are “confusing”, directly affecting the tourists’ experience. Second, the battery life is not enough. The receiver runs out of power after 6-8 hours, and the scenic spots and museums have to suspend services at noon, retrieve the equipment for charging, which seriously delays the tourists’ itinerary. Third, the multi-language support is insufficient. Facing international tourists, either there is no small language support at all, or it takes a long time to customize. Fourth, the operation is too complex. There are many buttons and confusing interfaces, and even the elderly and children take a long time to learn. There are also hygiene issues. Shared equipment for multiple people makes disinfection difficult, especially in high-end exhibition halls and hospital exhibition halls, where hygiene requirements are high. Ordinary equipment simply cannot meet the needs. These problems may seem insignificant, but they really affect the usage effect – for example, the scenic spots were complained about the battery life issue, and the museums were unable to retain international visitors due to language issues. These are not things that can be handled by “making do”.
II. Select products according to scenarios: The Yingmi M7 is suitable for most needs
A reliable manufacturer will not sell a single device all over the world. They definitely design products based on scenarios. The M7 neck-mounted self-service audio guide device from Yingmi is a typical “scenario-adapted model”, especially suitable for the following three types of users:
1.Scenic spots (5A/4A scenic areas, historical scenic spots)
When choosing equipment for scenic spots, the most important factors are whether the coverage is wide enough and whether the battery life can withstand it. The signal coverage of M7 can be adjusted from 0.5 meters to 40 meters, whether it’s a single viewing platform or a large scenic area, it can hold it; the transmitter battery life can last for 15 months, no need to frequently replace batteries, saving a lot of trouble; the receiver can work continuously for 16 hours, tourists receive the equipment in the morning and can browse until the closing time without charging. Moreover, it is a neck-mounted design, with the receiver weighing only 50 grams and the transmitter 27 grams, tourists wearing it for a day won’t feel tired, which is much more comfortable than those devices weighing over 80 grams on the market.
2.Museums / Memorials
When using a audio guide device in museums, the core is multi-language and large storage. M7 has 8 common languages including Chinese, English, and Japanese. If dialects or small languages (such as Thai, Arabic) are needed, it can be customized within 3 to 7 working days; it can also store 9,999 explanations, even for large museums with 50 exhibition areas, there is no need to update in batches, just import once. In addition, when working, M7 does not produce noise, it won’t disturb tourists from quietly viewing the exhibition, this is particularly considerate.
3.Corporate exhibition halls / government exhibition halls
For such scenarios, the equipment is most valued for its confidentiality and professionalism. The M7 uses spread-spectrum communication technology, which can prevent the leakage of the presentation content. Whether it’s an enterprise introducing its core products or a government presenting policies and plans, you can rest assured. Moreover, it supports a 220V global standard voltage, so if the enterprise has an overseas exhibition hall, it can be used directly without additional modifications. The equipment can also be customized with an appearance logo, which can enhance the level when receiving clients.

III. Actually, having good equipment is not enough; the accompanying service plan is the key to ease of mind
A reliable manufacturer not only sells equipment but also provides a complete solution throughout the process. Yingmi has thought quite thoroughly about this matter:

Customization for small languages is also fast; bulk purchasing services: if you purchase 50 sets or more, you will receive free on-site installation and debugging, and the staff will be taught how to operate and update the content. Even if you are a novice, you can quickly get the hang of it; after-sales guarantee is more reassuring. The M7 offers lifetime free maintenance/repair (excluding shipping costs), which is much more reliable than the common 1-3 year warranty in the industry. Moreover, there is a technical team online 24 hours a day, and any questions can be responded to within 1 hour, and the problem can be solved within 48 hours. There is no need to worry about the equipment breaking down without someone to take care of it.

Even if multiple people share it, there is no need to worry about hygiene issues. The all-aluminum storage box can hold 50 sets of equipment and accessories, is shockproof and anti-drop, and is convenient for transportation and storage. Subsequent purchase of charging cables, brackets, and other accessories can also get discounted prices. There is no fear of supply disruption.

From the first unit to the first million units of equipment, “zero accidents” have been achieved, which is not common in the industry; Second, the certifications are comprehensive. The M7 has passed international core certifications such as CE, RoHS, and CNAS, as well as software product certificates. Whether it is used domestically or exported to Europe, Asia, or Southeast Asia, customs clearance is not an obstacle, and the quality can be recognized globally; Third, the experience is sufficient. It has served over 4,000 customers, whether it is 5A scenic areas, provincial museums, or large enterprises and government agencies, it has mature adaptation plans, and the implementation is very stable.
V. Actually, choosing the right tour guide device is not complicated
There is no need to compare blindly based on a bunch of parameters. First, think clearly about your core needs: is it for scenic areas, museums, or enterprise exhibition halls? Do you need multiple languages? How much time will it be used every day? Understand these, and then contact Yingmi. They will design an adaptation plan for you for free. If you are unsure about the effect, you can apply for a trial of the M7 to experience the stability of the signal, whether the battery life is sufficient, and whether the operation is convenient.
In the end, choosing a wireless tour guide device, finding the right manufacturer is the key. Yingmi’s 18 years of industry experience, zero-accident reputation, and the M7’s practical scene adaptation ability and full-process service can handle everything from dealing with international tourists, resolving signal interference, to worry-free after-sales service. Instead of obsessing over “which one is cheaper”, it is better to choose a manufacturer that can truly solve problems and be reliable for a long time. After all, whether it is scenic area reception or museum services, reliability is the most important thing. Don’t you think so?
