For 16 years, we at Yingmi (YINGMI) have often heard overseas friends making jokes: If you want to ask "Why is this fruit called the Miracle Fruit?" in a scenic area, you have to approach the tour guide and shout loudly, but the people behind you can't hear you at all; when visiting the Huawei factory for an inspection, if you want to ask "What are the standards for the components of 5G base stations?", the traditional one-way communication device can only be used for listening and can only chase after the technicians; in a study tour group, when students are curious about "How were the Terracotta Army made?", their questions are drowned out by the noise from other groups - these "problems of not being able to ask or not being able to hear clearly" are actually the old problems of traditional one-way communication devices.

    To address these pain points in communication scenarios, we have specially developed the 008B two-way intercom wireless communicator. The core is to enable "asking without shouting and everyone in the group can hear clearly". Now, whether it's the tropical orchards in Hainan or the overseas factories of Huawei, they are all using it to solve interaction problems, helping over 100,000 overseas users communicate smoothly every year.

I. The "Communication Pit" of Traditional One-way Presenters: The Most Troubling Issue for Overseas Users

    In scenarios such as educational tours, corporate visits, and scenic area guides that require interaction, the shortcomings of traditional presenters are particularly evident for overseas users. These are the direct reasons for us to develop 008B:

1. Asking questions can only be done by "shouting", and the atmosphere is completely ruined.

    Traditional presenters only have the "listening" function. If you want to ask a question, you have to shout loudly. Not only does this interrupt the presenter, but it also disturbs others. For example, when guiding a Southeast Asian study tour group at the World Tropical Fruit Window in Qionghai, Hainan, Tour Guide Zhang always had to "shout loudly": "The sweetness difference between durian honey and pineapple honey is 30%!" However, the students in the back still couldn't hear clearly. Some people would crowd up to the fruit trees to ask questions, and the visiting route was all messed up. In a museum, which is a quiet place, overseas tourists were even more reluctant to shout because they knew they couldn't ask questions. They could only hold their questions in their minds.

2. When the team disperses, interaction "disappears"

    If the team exceeds 20 people or is in a factory workshop or open scenic area, the signal of traditional presenters simply cannot reach. Huawei's Shenzhen factory once told us that once a German supplier group was visiting, the customer asked "What is the material of the parts?" Only a few people in the front row could hear clearly. The technician could only go back and explain again, causing a delay of nearly half an hour.

3. Multilingual interaction "gets stuck", communication is like "guessing a riddle"

    Overseas users are most concerned about language issues. Traditional presenters simply cannot solve this: even if there is an English explanation, when users ask questions in their native language, non-native speakers cannot understand; for small language groups like Dutch and Portuguese, they can only rely on fragmented information transmitted through translation software, and it often gets transmitted wrong - once a French tourist wanted to ask "What is the brushwork of Wen Zhengming's calligraphy?", it changed the meaning when translated into English, and ultimately nothing was understood.

II. Yingmi 008B: Fill in the "Communication Pit", Two-way Interaction is Super Simple

    Our design of 008B is aimed at achieving "two-way communication and full team listening". From operation to signal, from language to safety, every detail is tailored to the habits of overseas users:

1. Core Function: One-click question, heard by the entire team

    008B completely changed the problem of traditional presenters being "only able to listen and not speak":
    Each receiver has a "question key", without having to get close to the presenter, just press it once to speak, and the signal is directly transmitted to all devices on the same channel - no matter if you are in the front row or the back row of a 30-person team, you can hear the questions and answers clearly. The tour guide Zhang in the Hainan scenic area said that now when students ask "Why is ice cream fruit called 'Tree-Harmony-Dasch'?", the entire team can hear it, and he doesn't have to repeat it repeatedly;
    The transmission is not laggy at all. It uses 4G FSK signal technology, and the delay from asking a question to getting an answer is less than 0.1 second, similar to face-to-face chatting, and there is no awkwardness like "No sound after asking for a long time";
    It can also control the order of speaking. The presenter can choose between "free questioning" or "ordered questioning" mode to avoid chaos when many people speak at the same time, which is particularly suitable for study tour groups, meetings, and other scenarios that require order.

2. Detail Design: Follow the habits of overseas users

    We do not engage in "showy" designs. Everything we do is to truly consider overseas users:
    The neck-mounted receiver is not lost and is lightweight: The receiver weighs only 35 grams and can be hung around the neck without holding it. Overseas tourists can take photos and handle things without any delay. After being used in the Hainan scenic area, the equipment loss rate dropped from 12% to less than 1%. An European tourist said, "It's as if it's not even on my neck, and I no longer worry about losing it";
    The signal is far enough to pass through walls: In open areas, the signal can reach 280 meters. In Huawei's 200-meter-long workshop and the forest of Jiangxi Longhu Mountain, the signal is stable. Even with several layers of concrete walls separating them, one can still hear clearly without the situation of "there's no sound beyond a certain partition".
    Multilingual version: Standardized with 8 main languages such as English, French, and Spanish, and switching can be done with a simple press; if there is a need for less common languages like Dutch or Portuguese, we can customize them within 3 days, without having overseas users have to accommodate the "universal language".

3. Noise reduction + Safety: Can be used in complex scenarios

    Overseas communication scenarios often encounter issues such as noise and equipment safety. 008B considered this early on:
    Embedded noise reduction technology (this is a patent of our country): It can automatically filter out noises, such as the machine sounds in factories and the crowd noise in scenic spots. The voices of questions and answers are particularly clear. In the crowded exhibition hall of the Shanghai International Import Expo, using 008B for communication, overseas buyers' questions were still clearly heard by the host;
    Battery safety guaranteed: We use our independently developed PMU safety lithium battery. During charging, we monitor the temperature and current in real time. From the 1st to the 100,000th unit, there has never been a single safety accident. It has also passed the EU CE and RoHS certifications, and can be used in Europe and America;
    Impact-resistant and durable: The body is made of ABS anti-drop material. When the overseas team was conducting outdoor research and factory inspections and accidentally dropped it on the ground, it did not break. There is no need to constantly worry about repairing the equipment.

III. Real Cases: The "Communication Transformation" of the Hainan Orchard

    Let's tell a true story of 008B in the Hainan World Tropical Fruit Window. This place covers 500 acres and grows over 400 kinds of rare fruits. Previously, the troubles in receiving overseas teams were all solved by 008B:

1. Before: The tour guide "shouted", and all interactions were troublesome

    Previously, tour guide Zhang Xiao of the scenic area was constantly troubled: "Durian honey and pineapple honey look similar. I have to shout to explain the differences. The tourists in the back row still couldn't hear clearly. Often, European tourists frowned and waved their hands - not because they didn't want to ask, but because they couldn't ask." When receiving Southeast Asian study tours, it was even more chaotic. Students surrounded the fruit trees and asked questions, and the visiting route was all disrupted. There were up to 8 groups of tours per day, and there were always complaints of "hard to hear".

2. Now: Two-way interaction, experience completely different

    In the spring of 2025, after using 008B, the communication atmosphere of this orchard completely changed:
    Questioning doesn't require getting close: Once an European tourist wanted to know "What does the taste of ice cream fruit resemble?", by pressing the question button, the entire group heard it. Tour guide Zhang Xiao immediately played the pre-recorded English explanation and added, "This fruit was once a sweet treat for the nobility in South America." The tourists all smiled and nodded.
    Interactions can be fun: In the mystery fruit experience area, tour guide Zhang used 008B to initiate a question: "Which fruit can make lemon taste sweet?" The Southeast Asian students rushed to press the question button to answer. Those who answered correctly could get fruit tasting coupons. The scene was particularly lively.
    Efficiency doubled: Now, 15 groups of tours can be received per day, and the complaint rate has been zero. The stay time of overseas tourists has been extended from 2 hours to 3.5 hours. The scenic area operation director said: "Previously, tourists were afraid of asking questions because of the trouble. Now, they actively ask this and that, and even the sales of cultural products have increased by 25%."
    Even more unexpectedly, 008B also became a "lost person finder" - once an elderly European tour group had an elderly member get lost in the jackfruit maze. We found the person through the positioning function of the device (connected to Yingmi's cloud backend), in just 10 minutes. The family said, "I didn't expect the explainer could also ensure safety."

IV. Full Scene Adaptation: 008B Can Be Used in Common Overseas Communication Scenarios

    008B is not only for scenic areas, but also for common overseas communication scenarios such as study tours, enterprise inspections, and exhibitions. It can be precisely adapted:

1. Study Tours: Interaction between teachers and students is effortless

    Overseas study tours (such as those coming to China to learn about culture and observe nature) particularly require interaction. The "orderly questioning" mode of 008B is just suitable. The international study tour group of Beijing Foreign Studies University used it to visit the Terracotta Army. When a student asked, "Why can the painted patterns last for thousands of years?", pressing a button enabled the entire group to hear clearly. When the teacher answered, the pictures (including our guided tour APP) could be played simultaneously, making the knowledge more comprehensible. The teacher in charge of the group reported： "Previously， students had to gather around to ask questions. Now， they can interact without moving， and the efficiency is much higher."

2. Overseas corporate visits： Technical exchanges not stuck

    When Huawei and Adidas receive overseas suppliers， they most need to solve the problem of "technical inquiries". Once a German client asked about "the heat dissipation material for 5G base stations" in the Huawei workshop， pressing the question button enabled the technician to answer immediately. The clients in the same group could all hear clearly， without having to ask one by one； the small language team was also convenient. Dutch clients could ask in their native language， and the equipment could switch to the corresponding language， without making mistakes in professional terms. After using it in the Shenzhen factory of Huawei， the satisfaction of overseas clients for the visit increased by 60%.

3. International exhibitions / conferences： Multiple teams interacting without interference

    At events like the Shanghai International Expo and the International Museum Forum， there are often multiple overseas teams present. 008B supports "multi-channel two-way interaction"： the French team uses channel 1， and the Japanese team uses channel 5. Team members can ask questions without disturbing each other； the tour guide can also switch to "bilingual mode"， for example， answering in English and then automatically playing the French version without repeating professional terms. For the 2024 International Expo， over 30 overseas enterprises used 008B， all saying "It's much smoother than before when using the microphone for interaction".

V. Yingmi's Guarantee：Overseas Users Can Use with Confidence

    The reason why 008B has been recognized by so many overseas customers is not only because of its good functionality， but also because of the global service capabilities we have accumulated over 16 years， which helps us solve "worries about the future"：

1. All international certifications are complete，usable globally

    008B has passed the EU CE and RoHS certifications. Whether in Europe， America， or Southeast Asia， it complies with the local electronic equipment standards； the product manual also has 8 language versions， allowing overseas users to understand how to operate at a glance.

2. 9G service：Both pre-sales and after-sales are worry-free

    Pre-sales： Responses are made within 90 seconds in English， and we can also send 008B samples for free trial. We have over 1，000 global customer cases (such as Huawei and the usage of the Barcelona Museum in Spain)， which can be used as references；
    During the sales process： If you need it urgently， it can be shipped on the same day， delivered through DHL or FedEx； we can also conduct on-site site surveys to help plan channels and customize small language content；
    After-sales：Equipment is covered by a lifetime warranty， and there is an 24-hour English customer service hotline (400-990-7677) that can be reached at any time； if it breaks down， it can be repaired within 10 days， and a backup machine can be provided without delaying the reception.

3. Old customers recognize it： It's based on genuine word-of-mouth

    Nowadays，major institutions like Huawei，Bentley Motors，and the Barcelona Museum in Spain are all using 008B for communication and reception. It's not just our boast； these customers have used it and think "It really solves the problem" - like the operations director of Hainan Fruit Window said： "Previously， tourists were afraid to ask questions， but now they actively chat， which is the value of 008B."

VI. Future：Make Two-way Communication More Smooth

    We haven't stopped optimizing. In the future， we will upgrade based on the needs of overseas users： such as adding AI real-time translation， for example， when French tourists ask in their native language， the equipment can automatically translate into Chinese for the tour guide，and then translate the answer into French； for study tours， we will add "question statistics" to help teachers know what students are most concerned about； offices will also be set up in Europe and Southeast Asia，closer to the users and more timely in service.
 

Conclusion: Make every communication crystal clear

    From the "fruit quiz" at the Hainan orchard to the "technical inquiry" at the Huawei factory, what Yingmi 008B aims to achieve is actually quite simple: To enable overseas friends in communication scenarios to no longer worry about "not being able to hear clearly or ask questions" anymore.
    If you are the head of an overseas research and study institution, an enterprise receptionist, or a scenic area operator, and are currently troubled by interaction issues, you might want to give 008B a try - it is not just an explainer, but also a "small bridge" that helps everyone communicate smoothly. In the future, we will continue to optimize these pain points to ensure that every communication for global users is clear and smooth.
