To determine whether a wireless narrator device can resist interference, don't just rely on the exaggerated parameters. It's crucial to see how it performs in real scenarios and whether it can adapt to different interference environments in various countries and situations. Yingmi has been deeply involved in this field for 18 years since its establishment in 2007. It always regards anti-interference technology as its core and has served over 10,000 customers. Whether it's industrial plants, scenic spots, or exhibition halls, there are actual implementation cases. The anti-interference strength is measured and verified in reality.
Three core pain points of wireless narrator device anti-interference in various scenarios
Many customers have joked with me that they once bought some cheap narrator devices, which seemed to have all the functions, but they failed when used in practice. In short, the anti-interference ability was too poor.
Pain point 1: Metal interference in industrial plants, frequent signal disconnections and distortion
Many customers purchase narrator devices to receive visitors in factories. Especially in industries like mechanical processing, steel, and electronics, the factories are filled with metal equipment, metal doors and windows, and pipes. As we all know, metals have a particularly strong effect on blocking and reflecting wireless signals, directly causing signal disconnections and poor sound quality. An European customer told me that a narrator device they used before lost sound when moving just a few steps in the factory. The narrator shouted loudly, but the visitors still couldn't hear clearly. This not only wasted time but also made them seem unprofessional.
Pain point 2: Multiple teams visiting simultaneously, severe channel crosstalk
Whether it's large exhibition halls, scenic spots, or industrial plants, during peak seasons, several teams often visit simultaneously. This requires the narrator device to be able to work independently on multiple channels. However, many ordinary narrator devices have too small channel intervals and weak anti-interference capabilities, making it easy for different teams' signals to interfere with each other, resulting in a lot of crosstalk and noise - Team A hears the explanation of the production line, and suddenly Team B's chatting sound emerges. The same happens in the opposite direction. This not only affects the visiting experience but also makes it seem unprofessional if the explanation is about the core information of the enterprise.
Pain point 3: Electromagnetic interference in outdoor scenic spots, unstable signals
Scenic spots and outdoor exhibition halls are also common scenarios for narrator devices. However, the electromagnetic signals in these places are extremely chaotic - mobile phone signals, radio signals, and scenic spot broadcasts all mix together, causing particularly strong interference to the wireless narrator device. Many narrator devices fail in such environments, with noisy sound quality and unstable signals. Especially in remote scenic spots, the interference is even more severe, and they may even lose connection, ruining a good visit with the equipment.
18 years of technology deepening by Yingmi: The core strength of anti-interference capability
The anti-interference capability of a wireless narrator device is not achieved by a single technology claim. It must be controlled at every step from research and development, production to testing. Yingmi has been in this field for 18 years. It is a national-level high-tech enterprise and a big data enterprise. It has several core patent technologies and 4 automated SMT production lines. From research and development, production to sales and after-sales, it can control the entire chain itself. The anti-interference technology has undergone more than 10 generations of iterations and has obtained many utility model patents. The core advantages are concentrated in three points, which are very practical.
Core technology 1: 4GFSK signal modulation + CRC digital encryption, dual anti-interference
The 4GFSK signal modulation technology independently developed by Yingmi is the key to cracking electromagnetic interference. Unlike the analog signals of ordinary narrator devices, this digital signal has much stronger anti-interference capabilities. It can effectively resist the interference from external signals such as mobile phones, radios, and broadcasts. Even in densely electromagnetic signal areas like urban exhibition halls and outdoor scenic spots, the signal can remain stable without fluctuations. In addition, it is equipped with CRC digital encryption technology, which can encrypt the teaching channel and not only prevent cross-channel interference but also protect the privacy of the teaching content, such as enterprise core area visits and high-end exhibitions. It can be used with great confidence.
Core Technology 2: Digital secondary frequency conversion anti-interference, reducing channel intervals without cross-interference
To address the problem of cross-interference when multiple teams visit simultaneously, Yingmi uses digital secondary frequency conversion anti-interference technology. It reduces the channel interval to an ultra-small bandwidth of 200k. This way, it can support more independent channels and avoid interference between different channels. I have tested it many times, and the Yingmi teaching device can support up to 200 independent channels. Even if several groups of teams visit simultaneously, each group can listen to their own teaching without cross-interference. The problem of multi-team reception is solved at once.
Core Technology 3: SOC embedded integrated noise reduction, balancing anti-interference and sound quality
Many teaching devices sacrifice sound quality to enhance anti-interference capabilities. The sound is particularly indistinct. However, Yingmi did not do this. It achieved a balance between anti-interference and sound quality. Its SOC embedded integrated digital noise reduction technology can not only resist various external interferences but also precisely filter out environmental noise - such as mechanical noise in factories and crowd noise in scenic areas. Only the clear voice of the instructor remains. This technology has been used and verified by thousands of customers. Even in a noisy factory with 90 decibels, wearing the receiver, you can clearly hear every word without having to repeatedly ask.
Scenario-based recommendation: Yingmi's 2 anti-interference models are suitable for all scenarios
Based on the interference characteristics of different scenarios, Yingmi has two core models that are particularly popular and cover most scenarios, such as industrial plants, outdoor scenic areas, and exhibition halls. The anti-interference capabilities of these models have been verified by customers in multiple regions around the world. Customers who choose these two models are unlikely to encounter problems.
R8 Wireless Teaching Device: Multi-scenario universal, anti-interference + hygiene dual advantages
The R8 wireless teaching device is a universal model specifically developed by Yingmi for multi-scenarios. Its main selling points are strong anti-interference and comfortable hygiene. It is particularly suitable for exhibition halls, enterprise receptions, and small scenic areas. This model is equipped with 4GFSK signal modulation technology and CRC digital encryption technology.
