When a Spanish machinery manufacturer went to Germany to attend an industrial exhibition, they encountered a rather troublesome problem. The wireless tour guide devices they had purchased started to have interference when they were placed in crowded exhibition halls. German language explanations mixed with English introductions from neighboring booths, making it impossible for potential customers to understand the core parameters of the products. What was worse, the equipment claimed to have a 10-hour battery life, but in reality, it only lasted for 6 hours. During the afternoon negotiation sessions, the power outage caused the sessions to be interrupted several times, resulting in the loss of many opportunities.
Later, they changed their cooperation factory and chose the automatic sensing tour guide system from Yingmi. The effect was completely different. The signal was extremely stable, and there was no more interference. The 12-hour long battery life was just enough to cover the entire exhibition. Moreover, this equipment was defaultly equipped with 8 languages, and it could be customized for minority language needs. Different country buyers could easily understand the product advantages. As a result, the order volume of this exhibition was 35% higher than the previous one.
In fact, this kind of situation is very common in international exhibitions, museums, and enterprise visits. Choosing a reliable factory for manufacturing wireless tour guide devices is not just about buying a device; it is also a key to ensuring smooth cross-language communication.
I.Hidden Pain Points in Wireless Tour Guide Device Procurement
When doing cross-border business and needing wireless tour guide devices, there are many pitfalls to watch out for during the procurement process.
1.Signal Interference
When multiple teams use the devices simultaneously, ordinary equipment is easily affected by mobile phones and WiFi signals, either losing connection or experiencing interference. The content of the explanation cannot be accurately transmitted.
2.Battery Life Issues
False battery life claims are particularly frustrating. Many factories claim that the device can last for 10 hours, but in reality, it only lasts for 5 or 6 hours, failing to meet the needs of an entire day’s exhibition or factory visit.
3.Poor Sound Quality
Poor sound quality is a major obstacle for cross-language communication. Poor filtering of environmental noise makes it difficult for non-native speakers to grasp the key information.
4.Complex Operation
Complex operation also increases the cost of use. The cumbersome pairing processes and button designs are confusing for temporary users. More importantly, some factories’ products lack international certifications such as CE and RoHS, causing problems during customs clearance and even burning the equipment due to voltage incompatibility. Slow response in after-sales service is also a headache. Repairing the device takes several weeks, seriously affecting normal use.
II. Yingmi‘s Precise Adaptation to Scenarios
1.International Exhibitions: Multi-language + Long Battery Life, Seamless Communication
The characteristics of international exhibitions are dense crowds, long communication time, and the need for multiple languages. Yingmi 007B is a radio frequency and infrared dual-mode automatic sensing device. It does not require manual pairing. Exhibitors can trigger the explanation by approaching the transmitter, eliminating the hassle of operation. The device is equipped with high-density lithium batteries, which can last for 12 hours after a single charge. Combined with an intelligent charging box, it is also convenient for batch fast charging.
It defaults to supporting 8 languages. If there is a need for minority language customization, it can be done. Regardless of which country’s buyers, they can understand the product advantages. It also has high-definition noise reduction technology, which can filter out the noisy environment in the exhibition hall, ensuring that the explanation content is clearly transmitted and not missed due to environmental noise.
2.Museums / Exhibition Halls: Precise Sensing + Multimedia, Excellent Immersive Experience
The exhibits in museums are usually densely placed, and the distance between the explanation points is short. Ordinary devices are prone to false triggering. However, 007B’s sensing is extremely precise. It will automatically play the explanation when you approach the corresponding exhibit and stop when you leave. There will be no errors. It is equipped with a 2.8-inch 4:3 true color LCD screen, which can not only play audio but also video and slideshows. Combined with the map navigation function, visitors can more intuitively understand the exhibit information. The equipment is designed for lightweight and is very comfortable to wear, making it suitable for long-term visits. It also supports a wide voltage range of 100V-240V, which can be directly used in any country around the world without the need for an additional transformer, saving a lot of trouble.
3.Factory visit: Stable transmission + Durability, suitable for complex environments
The factory workshop is noisy with spacious space, and the requirements for the audio guide are higher. The 007B uses 4GFSK signal modulation technology, which has extremely strong anti-interference ability. The transmission is stable within a range of 200 meters, without any delay. The body is made of wear-resistant material, which can adapt to the complex environment of the workshop. The digital noise reduction technology can effectively shield machine noise, allowing the visiting group to clearly hear the explanations of the production line.
In addition, it can also be used in conjunction with team-led equipment explanations. Whether it’s a small-scale technical exchange or a large-scale business investigation, it can flexibly meet the needs and is a good helper for enterprises to receive visits.
