Those who do volunteer work know that whether guiding at scenic spots, receiving visitors at exhibitions, or explaining at museums, the biggest challenge is that “good content doesn’t spread.” In noisy environments, voices become hoarse from shouting, yet audiences still can’t hear clearly. Wanting to cooperate with experts to supplement information, but constantly grabbing the microphone and disrupting rhythm. Encountering international audiences with language barriers, relying only on gestures. Equipment suddenly runs out of power, channels take forever to adjust, and things still don’t work right. This delays service and affects everyone’s experience.
For many years, Yingmi Technology has been deeply involved in wireless interpretation, always focusing on these volunteer service pain points. The Yingmi E8 team guide we developed doesn’t have fancy functions. It’s designed to “solve practical problems.” Anti-interference, dual narration capability, easy operation, and long battery life. From scenic spots to exhibitions, domestic to international, it lets volunteers stop being held back by equipment and focus on telling their stories well.
The old equipment can’t handle these “annoying things” in volunteer services
Whether peak-season guiding at 5A scenic spots or receptions at international exhibitions, volunteer problems are roughly the same. These issues may seem minor but actually reduce service efficiency.
1. In noisy environments, explanations sound like “mosquitoes chirping”
Popular scenic spots and exhibitions are always crowded and noisy, and traditional loudspeaker sounds simply “don’t carry.” Last year, Xiao Li, a volunteer at Gulangyu Scenic Area in Xiamen, led a group of 20 people through Shuzhuang Garden. The loudspeaker was at maximum volume, but back-row tourists only heard “Shuzhuang Garden” and “Republic of China.” They kept asking, “Why did the owner build this garden back then?” After an hour-long presentation, Xiao Li repeated key information at least ten times. By the end, his voice was so hoarse he couldn’t speak.
At an Adidas exhibition in Shanghai, volunteer Xiao Zhang introduced new sports equipment. The exhibition area had machine roars and crowd noise mixing with the loudspeaker. A German buyer leaned close to Xiao Zhang, practically pressing his face to ask, “What’s the shock-absorbing material in this running shoe?” Xiao Zhang could only slow down and shout one-on-one. Originally planning to lead 10 audience groups, he only completed 6 and was sweating profusely.
2. Wanting to cooperate with experts but always “fighting for the microphone”
Often volunteers explain basic content while experts supplement professional details. But with traditional equipment, only one person can explain continuously. Xiao Wang, a volunteer at Henan Provincial Museum, gave a lecture on Tang Dynasty terracotta figurines. A cultural relics expert wanted to add that “the glaze came from Persian cobalt,” but they had to wait until Xiao Wang finished. By then, audiences had shifted attention to the next exhibit. As soon as the expert started, someone asked, “Is there more about that terracotta figurine?” The on-site rhythm completely broke down.
Huawei’s industrial exhibition was more typical. Volunteers explained production line processes while a technician wanted to interject, “This line saves 15 kilowatt-hours per hour.” They took turns with one microphone. During the few seconds of pause, some audience members thought the explanation ended and turned to leave. The technician could only awkwardly follow up with more additions.
3. International audiences are “completely lost,” language barriers impede communication
Many international activities happen now, and volunteers often encounter international audiences, but language becomes a major obstacle. Xiao Chen, a volunteer at Taihu Lake Scenic Area in Suzhou, wanted to tell foreign tourists about “Taihu’s Three Whites” fishing culture. Without bilingual equipment, he could only use phone translation software. Tourists smiled and nodded, finally asking the translator quietly, “When can we eat the silver fish he just mentioned?” They clearly missed the key point.
Chinese volunteers at the Louvre in France previously led international tours speaking only English. Spanish and Italian tourists couldn’t understand, looking at English exhibit signs. A Spanish tourist said, “I only understood half the Mona Lisa story. What a pity!”
4. Equipment “falls apart,” hard to operate and not durable
Most volunteers aren’t technical and can’t handle complex equipment. Previously, some volunteers used certain audio guide brands. When changing exhibition areas, they had to manually adjust channels. Pressing the wrong button caused noise. Once, after five minutes of adjusting, audiences became impatient and left halfway. Some devices only lasted 4 hours on battery. Starting service at 10 a.m. and running out by 2 p.m. meant volunteers borrowed temporary devices, leaving an hour with no explanation. Audiences complained they came for nothing.
Yingmi E8: A tailor-made explanation assistant for volunteers
When developing E8, we thought, “What volunteers want isn’t high technology, but usability and peace of mind.” So from technology to design, every aspect focuses on the pain points mentioned earlier:
1. No lag when two people speak together, smooth cooperation between volunteers and experts
E8 supports “primary and secondary dual speaking.” Volunteers and experts each carry a transmitter. No competing for the microphone. They fill in whenever needed. Sound transmission has zero delay, and audiences can’t detect any “switching sensation.”
Xiao Wang from Henan Provincial Museum now discusses terracotta figurines. Cultural relics experts chime in anytime: “This terracotta figurine’s cobalt came from Persia. Back then, it took half a year to reach Chang’an along the Silk Road.” The two work in harmony. Audiences understand both history and craftsmanship. At Huawei’s Industrial Exhibition, volunteers explained the production line while technicians simultaneously added, “Energy-saving parameters can be customized during mass production.” No waiting or interruption, and explanation efficiency was 30% higher. The technician said, “Before, we feared interrupting volunteers. Now we can supplement anytime. Audiences understand clearly and we’re at ease.”
2. Just press and it turns on. Use it without learning
The E8’s receiver is particularly simple. Press the SET key to turn on, and it automatically searches for nearby transmitter signals. Connection takes only 3 seconds, eliminating manual channel adjustment. The transmitter’s LCD screen clearly shows channel, battery level, and volume. Volunteers see equipment status at a glance without consulting manuals.
Xiao Chen from Taihu Lake in Suzhou used E8 for the first time. Moving from the pier to the island exhibition area, he turned the receiver off and on again, directly connecting to the new transmitter without wasting a second. Chinese volunteers at the Louvre led international tour groups. Foreign tourists received receivers, pressed the power button, and heard sound. Nobody asked, “How do I change channels?” Xiao Chen said, “Before, it took half a day to adjust equipment when changing areas. Now we start using it right after turning it on. Time saved lets us cover two more scenic spots.”
3. Long battery life, very easy to use, super convenient management
The E8’s receiver runs 8-10 hours on one charge, providing service from 9 a.m. to 6 p.m. Battery power is more than sufficient. The 36-slot or 48-slot contact charging case that comes with it is even more convenient. Just place the receiver in the slot and it starts charging, no wires needed. It also has ultraviolet disinfection. Sanitize after each service day, and use it with confidence the next day.
A certain exhibition’s volunteer team has 50 people. They use a 50-unit storage case to carry equipment. During transport, internal EVA shock-absorbing cotton protects machines and prevents bumping. Previously, daily charging and tidying took one hour. Now it only takes ten minutes. The person in charge said, “There’s never been equipment running out and service stopping again. Time saved can train more volunteers.”
From domestic to global, E8 helps volunteers spread their stories far and wide
E8 works not only in China but also solves volunteer problems internationally. Whether museums in Europe, scenic spots in Southeast Asia, or exhibitions in the Americas, core requirements remain the same: clear hearing, easy cooperation, and simple operation.
After volunteers at the Louvre in France used E8, international tour group feedback improved significantly. A Spanish tourist said, “Finally I can clearly understand the Mona Lisa’s creation details without relying on translation.” Italian tourists felt, “It’s so comfortable being able to wander freely without following tour guide crowds and hearing explanations clearly.”
Volunteers at Phuket, Thailand scenic spots previously used megaphones. When sea breeze blew, no sound carried and they could only speak close to tourists. Now with E8, no matter how strong the breeze, tourists clearly hear “coral reef no-mooring areas” within 200 meters. When Chinese tourists switch to the Chinese channel, they still hear “how island fishermen cooperate with ospreys to catch fish,” without relying on tour guide demonstrations.
At a Las Vegas electronics show, volunteers led buyers through multiple booths. Previously, changing booths required channel adjustment, wasting time. Now with E8, when changing booths, receivers automatically connect to new channels. Volunteers and technicians explain in coordination. Chinese buyers said, “This time explanations went very smoothly. All parameters needing understanding were clear. No repeated questions. Much higher efficiency.”
Yingmi Technology: helping volunteers convey every word accurately
Yingmi Technology developed E8 not to sell a “sound-making device” but to serve as a “caring helper” for volunteers. Enabling them to focus on saying what they should say and spreading the culture they should convey, without shouting, worrying, or panicking.
We also promise: 90-second rapid response to pre-sale inquiries, free sample delivery for volunteers to try first. If needed during sales, we visit your location to assess service scenarios. Urgent orders ship same day. After-sales service reassures. SF Express offers free shipping for repairs, and they also provide spare equipment. If it breaks, there’s lifetime warranty. We just don’t want equipment problems delaying volunteer services.
Until now, E8 has served over 4,000 clients worldwide, from Xiamen’s Gulangyu Island and Henan Museum, to Huawei and Adidas exhibitions, even to the Louvre in France and Phuket, Thailand. Behind all these events stand smooth volunteer service figures.
We know volunteer voices carry culture and enthusiasm, deserving to be clearly heard by every listener. In the future, we’ll add more practical functions to E8: adding more minority languages so volunteers in more regions can use it, optimizing cloud management to facilitate pre-recording explanation scripts, making equipment lighter with longer battery life to further reduce volunteer burden.
Whether at domestic scenic spots or international exhibitions, Yingmi E8 wants to accompany volunteers, smoothly conveying every story and detail to audiences. Making volunteer services easier and cultural exchanges more borderless.
