So far, I have witnessed too many “communication predicaments” at various exhibitions: At a certain chip booth at the Shanghai Electronics Show, the explainer had just finished describing the application scenarios of the product, but the technical director next to him wanted to add details about the chip manufacturing process. As soon as he started speaking, his voice overrode that of the explainer. The audience below either moved closer to the director or stared at the explainer, and the volume of the sound from the headphones fluctuated. At the Guangzhou Building Materials Show, an enterprise representative wanted to cooperate with the explainer to introduce the new product’s environmental protection performance. The two of them took turns speaking but were constantly interrupted. In the end, the representative had to stand by and wait for the explainer to finish. The originally 10-minute explanation was stretched out to 15 minutes, and one-third of the audience left halfway through.
It wasn’t until last month at an intelligent equipment exhibition held in an international convention center that I came across the Yingmi E8 wireless audio guide system – this device, which supports “primary and secondary simultaneous interpretation“, completely changed my perception of exhibition interpretation. From 9 a.m. to 5 p.m. when the exhibition closed, I experienced it throughout the day at different booths. Whether it was the cooperation between interpreters and technical experts, or the collaboration between enterprise leaders and product managers, this system made “primary and secondary simultaneous interpretation” smooth and effortless. Especially the use experience of the headset receiver was precisely what hit the many pain points of the exhibition attendees.
Why doesn’t the commentator’s voice get stuck?
After experiencing the live event, I specifically talked to the staff and learned that the “no lag when two people speak simultaneously” is not an accident; it is the result of the comprehensive design of this system from hardware to technology.
Anti-interference capability
The exhibition site is always very noisy. Mobile phone signals, as well as the amplification equipment from other booths, can all affect the transmission of the explanation sound. However, the Yingmi E8 system uses U-band high-frequency radio waves ranging from 860 MHz to 870 MHz, along with 4G FSK signal modulation technology. The staff gave me an example, saying that it’s like opening a dedicated lane on a crowded road. Even if there are other signals “vehicles” around, this system’s “signal vehicle” can still move smoothly. When I tested it myself, I deliberately went to the signal blind spot of the exhibition (such as near the storage room in the corner of the exhibition hall), and the sound in the earpiece receiver was still clear, without any interruption or noise.
Zero-latency transmission
Many people are concerned that the “main and secondary simultaneous speaking” method might cause sound delays. For instance, when A finishes speaking, B immediately follows up, and as a result, the audience hears A’s words not yet finished, and B’s words have already intruded. However, Yingmi used a combination of “reliable zero-delay radio receiving front-end + digital audio processing back-end”. The staff said, “The transmission delay can be controlled at the millisecond level, and the human ear cannot even detect it.”
Automatic channel following function
This is extremely useful for exhibition staff. Previously, when using other interpretation systems, every time a booth was changed or a different interpreter was used, manual channel adjustment was required. If not careful, the channel might be set incorrectly, and the audience could only hear noise. However, with the Yingmi receiver, simply pressing the SET button to turn it on enables it to automatically search for and connect to nearby transmitter signals. I tried it out. From the sensor booth to the adjacent robot booth, after changing to a different transmitter, the receiver automatically connected to the new channel within 3 seconds after turning on. I didn’t have to manually adjust any buttons. The channel, volume, and battery level of the transmitter are clearly visible, and there’s no need to worry about sudden power outages.
Suitable for various scenarios of exhibitions
Apart from the dual-person simultaneous speaking mode, I also discovered that wireless audio guide system can be adapted to various scenarios of the exhibition, and each scenario can solve practical problems.
VIP customer reception
Many enterprises will invite important clients or leaders to visit their booths at exhibitions. At such times, there is often a need for an interpreter to introduce the products and a person in charge to provide additional details about the cooperation. I once saw an enterprise that, in order to ensure the cooperation between the leader and the interpreter, specially prepared two microphones. However, the sound interfered with each other, and the client could only switch the headphones repeatedly. But with the Yingmi system, the leader and the interpreter each wore a transmitter, and the client wore a headset receiver. Both could supplement at any time without having to switch equipment. At the robot enterprise booth in the intelligent equipment exhibition, the person in charge accompanied a purchasing director from a listed company on a visit. The interpreter said, “This robot can handle loads up to 50kg,” and the person in charge immediately responded, “If it’s bulk purchase, we can provide customized programming services.” The purchasing director listened attentively and nodded. Finally, they agreed on a time for detailed discussion on the spot.
Technical forums or new product launches
At exhibitions, there are often small forums where the speaker finishes their presentation, and then the guests need to ask supplementary questions or share their opinions. Previously, either the microphone was used for transmission or the guests would approach the speaker’s microphone, which was very inconvenient. But with the Yingmi system, the speaker and the guests each carry a transmitter, and the audience wears ear-mounted receivers. The guests can speak at any time and the audience can also hear clearly.
Multiple booths can be used simultaneously
In large-scale exhibitions, often multiple booths of the same enterprise are set up. For example, an electrical appliance company sets up three booths for refrigerators, washing machines, and air conditioners at the exhibition. Each booth requires explanation. If using the traditional system, it is very likely to have channel crosstalk, and the audience may hear the explanation from the refrigerator booth mixed with the sound from the washing machine booth. However, the Yingmi system has 200 channels available for selection. The three booths are assigned channels 101, 120, and 150 respectively, and their respective explanations are completely non-interfering. When I experienced the refrigerator booth of that electrical appliance company, I deliberately tuned to other channels, and only then could I hear the sound from the washing machine booth. During normal use, the earpiece receiver will only receive the current connected channel and will not have crosstalk.
The convenience of equipment management
After the exhibition, the problem of equipment storage and charging was a big headache – some of the presentation equipment we used before required individual power plugs for charging, and the storage process was prone to damaging the devices. However, Yingmi has a dedicated contact-type charging box with a 36-bit or 48-bit design. Just place the ear-mounted receiver into the slot and it can be charged – no need for power plugs. The charging box also has an ultraviolet disinfection function, which is very important after many people use the headphones for disinfection during the exhibition. The staff showed me their storage box, which contains EVA shock-absorbing cotton. Each receiver has an independent slot, so even if there is jostling during transportation, there is no need to worry about equipment damage. “We brought 50 receivers to the last exhibition, and with a 50-bit storage box, they could all fit. The transportation was very convenient,” said the exhibition manager of a certain enterprise.
The efficiency of exhibition explanations
I have witnessed numerous disappointments caused by “inadequate explanation”: the enterprise failed to convey all the information, the client failed to hear the detailed content clearly, and the low reception efficiency also affected the brand image. However, the E8 wireless audio guide system, with its core advantage of “no lag when two people explain simultaneously”, combined with the lightweight and comfortable wearing experience, stable anti-interference performance, convenient equipment management, and reliable service, has completely solved these problems.
For the exhibition staff, this system is not merely a “presentation tool”, but rather a “helper” that enhances reception efficiency and showcases the professionalism of the enterprise – the interpreters and technical experts can simultaneously convey information, the leaders and product managers can collaboratively answer questions, and the audience no longer has to “filter information” amid chaotic sounds; everyone can easily obtain the content they need.
If you are also someone who frequently attends exhibitions, you might want to give this E8 wireless audio guide system a try. Believe me, when you experience for the first time the smoothness of “two people speaking simultaneously without waiting, clear sound without lag”, you will understand: Exhibition presentations can be so effortless and efficient.
