Yingmi offers customized solutions for all scenarios

A self-guided audio guide system is a handheld receiver that tells visitors about what they are looking at without a human guide. In an auto-trigger system, small RFID trigger points are placed beside the exhibits, and the receiver plays the matching commentary by itself when the visitor walks up. Nobody types a number or presses play. The idea is simple, and it is why this kind of guide has become common in museums, heritage sites and visitor centers. A person with a guide system leads a group at th e group's pace. A self-guided one lets each visitor set their own, so ten people in the same room can stand at ten different objects and each hear the right story. Why not make visitors press a number? Number-entry guides work, but they ask the visitor to do a small chore at every stop: find the number, type it, check it. Most people do this faithfully for the first few rooms and then skip stops, mistype, or give up and look at their phone. Automatic triggering removes the chore. The visitor walks, looks and listens, and the device keeps up. For a collection where the experience matters more than the lowest possible budget, that is usually the better trade. What happens between the exhibit and the ear There are only two parts. A trigger point is fixed near each exhibit, and it carries that exhibit's identity. The receiver in the visitor's hand picks it up when they come close, finds the audio segment with that identity, and plays it in the language the visitor chose at the start. Leave the area and it stops; reach the next exhibit and the next segment begins. Because the trigger points are separate from the audio, the two can change independently. Move an exhibit and you move its trigger point. Replace the commentary and the trigger stays where it is. That separation is the main reason these systems are easier to live with than they look. Where it works well, and where it doesn't Auto-trigger guides suit places where visitors browse at their own speed and objects are spaced far enough apart that each has its own spot to stand: museums, galleries, heritage buildings, corporate visitor centers. They are a poor fit for very dense displays, where a dozen small items share one case and any trigger would play over the others. They are also not a replacement for a live guide when the visit is built around conversation. A school party that needs questions answered wants a person and a tour guide system, not a recording. Whatever the site, test on your own floor. Layout, walls and crowds all change how triggering behaves, and a short trial in the actual gallery will tell you more than any brochure. A closer look at the M7 The YingMi M7 is built for exactly this job. It is a compact white receiver with a small display on the front, and at 50 grams it is light enough that visitors forget they are holding it. It stores up to 9,999 segments in 8 languages, so even a large site can give every exhibit its own commentary in every language it needs. A full charge lasts at least 16 hours, which covers an opening day with margin, and the trigger points run for 15 months or more on their own batteries, so the installation does not need attention every few weeks. Those numbers are worth checking against your own plan: how many exhibits, how many languages, how many hours you open. If the answers fit, the main remaining job is the commentary itself, which is where most of the real effort goes. FAQ What is a self-guided audio guide? It is a handheld device that plays commentary for each exhibit without a human guide. In an auto-trigger version, the audio starts by itself when the visitor reaches the exhibit. How does an RFID audio guide know which exhibit I am at? A small trigger point beside each exhibit carries its identity. The receiver picks it up as you approach and plays the matching audio segment. Is a self-guided system better than a tour guide system? Neither is better in general. Self-guided suits independent visitors who move at their own pace. A tour guide system suits groups led by a live guide. Some sites use both. Does an auto-trigger guide work when exhibits are close together? It can, but test it. Where many objects sit within a few steps of each other, check how the system keeps neighboring triggers from overlapping before you finalize the layout.

They use it to turn a demo into something people stay for. A wireless tour guide system puts the presenter's voice in each listener's ear, so the audience can stand anywhere in the booth, hear every word at normal volume, and the hall around them stops mattering. Picture a booth at eleven in the morning on day two. The presenter has a headset microphone and a small speaker on a stand, and the neighbouring booth has a video wall with a soundtrack. Four people are listening. Six more are standing at the edge of the aisle, close enough to see the product and too far to hear anything, so they drift on. The presenter reacts the way most of us would: turns the speaker up. The neighbour's soundtrack, mysteriously, gets louder too. Quieter, not louder The usual instinct at a trade show is to win by volume, and it is a race nobody wins. In-ear audio goes the other way. The presenter speaks the way they would across a table, the listeners hear it clearly through a receiver, and the floor around the booth gets quieter instead of noisier. Organizers like that. So do the exhibitors next door. There is a cost, and it is worth being honest about it. A loudspeaker pulls in people who were only walking past, because they overhear a sentence and slow down. Receivers do not do that. Whoever puts one on has already decided to listen, and the ones who would have overheard never get the chance. So this works best for scheduled demonstrations that people come to, and much less well for a booth that depends on drifting traffic. If your best leads tend to arrive by accident, think carefully before replacing the speaker entirely. What you gain in exchange is attention. A visitor holding a receiver is committed in a small way, and they tend to stay for the whole demonstration instead of for fifteen seconds of it. The handout matters more than the equipment: one person at the edge of the booth, one sentence of explanation and the receiver in the visitor's hand before they have time to think. Launches are a different animal A product launch has the opposite problem. Nobody is wandering past. Press, partners and key customers have been invited, and the risk is that the people at the back of the room, or those who wander over to photograph the product, miss what the presenter says about it. Guests also tend to talk to each other quietly while the presenter is speaking, which is fine in a small room and ruinous in a large one. Receivers let the room stay social without the presenter having to compete with it. People can move, take photos and murmur to a colleague, and still hear the announcement clearly. After the presentation, with no loudspeaker echo in the room, the conversations that follow, which are often the real purpose of the event, are easier to have. For either kind of event, the YingMi L7 is the kind of equipment that suits the job. It is an ear-hook receiver, which goes on quickly and stays put, and it works on UHF with 150 transmit channels and 102 receive channels, which leaves room to run more than one presenter at once without them colliding. Whatever you choose, try it on the show floor before the doors open, in the spot where your audience will really stand. Exhibition halls are crowded with other people's wireless equipment, and a quick word with the organizer about channels is worth more than any specification sheet. Plan the dull parts early too. Decide how many receivers your busiest session needs, plus a few for the ones that leave in pockets, and work out where they charge overnight. A show lasts several days, and nobody has time to solve the problem on day three. FAQ Should a trade show booth replace its loudspeaker with a tour guide system? Only if your presentations are scheduled and people come specifically to see them. If most of your leads come from passing traffic, a loudspeaker still helps draw them in. Does the system translate for international visitors? No. It carries the presenter's voice. For other languages you need a presenter or interpreter on a separate channel for each one.

By building the audio around the exhibits, not around the route. If every exhibit has its own numbered segment, in every language, with room left in the numbering for what comes next, then changing an exhibit means replacing one segment instead of rewriting the tour. Science and technology museums change faster than almost any other kind. A touchscreen is retired, a hall is rearranged for a touring show, a demonstration is rebuilt after a software update. The wall text gets fixed within a week. The audio guide is usually the last thing anyone remembers, and for a while it keeps describing an exhibit that is no longer there. Visitors notice, and they stop trusting the device. One exhibit, one segment The most common mistake is to write the audio guide as a single story that walks from the entrance to the exit. It reads well, and it is a nightmare to maintain, because moving one exhibit means touching the sentences before and after it. A better habit is to write each exhibit as a self-contained piece that makes sense on its own, with a short opening that says where the visitor is and a clean ending. Give each piece its own number. Then leave gaps. If hall A uses numbers in the 100s and hall B uses the 200s, a new exhibit in hall A can take the next free number instead of pushing everything down the line. It sounds trivial and it saves hours the first time a gallery is reorganized. Every language multiplies the work A change to one exhibit is not one change if the guide runs in eight languages. It is eight scripts, eight recordings and eight checks. Museums that underestimate this tend to update the home language promptly and let the others lag, which is how a visitor ends up hearing the old description in French while the English has moved on. Keep a master text for each exhibit and treat translations as dependent copies. When the master changes, every translation is marked as out of date until someone has signed it off. A shared spreadsheet is enough. What matters is that nobody has to remember. Treat an audio update like an exhibit change Exhibit changes already have an owner, a date and a sign-off in most museums. The audio should ride on the same process. Whoever approves the new display also approves the new commentary, and the audio is checked on a real device in front of the real exhibit before it goes live. Walk to the spot, wear the receiver, and listen. Mismatches between the words and the object are very easy to hear and very hard to find on a laptop. Update in batches rather than one exhibit at a time, and put new audio on every unit, including the spares in the cupboard. Nothing is more confusing than half the fleet carrying last month's content. Where the M7 fits The YingMi M7 is a self-guided receiver that plays commentary automatically when the visitor reaches an RFID trigger point, so each exhibit's segment starts by itself and no buttons are involved. It is a compact white unit with a small display on the front and weighs 50 grams. It stores up to 9,999 segments in 8 languages, which is a lot of headroom for a museum that adds and replaces exhibits all the time. The receiver runs for at least 16 hours on a charge, and the trigger points are rated for 15 months or more on their own batteries, so a full opening day and a season of operation do not call for constant maintenance. Whichever system you choose, work out in advance how new audio reaches every unit and how long that takes for your whole fleet. A system that holds thousands of segments is only useful if loading a batch of new ones is something your team can do between closing and opening. FAQ How often should a science museum review its audio guide? Every time an exhibit changes, and at least once a season for the rest. Tie the review to the exhibit change process so it does not depend on someone remembering. Is it better to organize audio by route or by exhibit? By exhibit. Each segment should make sense on its own, so one exhibit can change without rewriting its neighbors. Does a trigger-based audio guide work when exhibits sit close together? It can, but test it. Check how the system handles neighboring trigger points on your own floor before you finalize the layout.

By making sure the guide can be heard, and just as importantly, that the guide can hear the group. A two-way tour guide system gives the host a voice that cuts through turbine or boiler noise and gives a visitor a way to speak up when something is wrong, which a one-way system cannot do. Most people think of noise first when they picture a tour of a power plant. It is the obvious problem, and a wireless tour guide system deals with it well. The less obvious problem is what happens when the group has to hear something that matters: step back, wait here, do not touch that rail. In a loud hall, a shouted instruction reaches the first three people. The rest see their colleagues move and follow a beat late. A plant tour is mostly a safety briefing that happens to be interesting Energy facilities rarely host visitors for entertainment. They host regulators, students, community groups, customers and investors, and in every case the first duty is that nobody gets hurt. That changes what the audio equipment is for. In a museum, a missed sentence costs a visitor a fact. In a plant, it can cost someone a step into the wrong place. So the sensible way to think about the equipment is as part of the safety arrangements, not as a courtesy for guests. That does not make it complicated. It means the questions to ask are different. Hearing and being heard One-way systems are fine when the guide is the only person who needs to speak. On an industrial route that is often not the case. A visitor falls behind. Someone feels unwell. A group member notices something the guide has not. If the only way to say so is to walk up to the front through a noisy hall, many people will not bother. A two-way setup changes the dynamic. The person at the back can speak and be heard. The escort who walks behind the group can talk to the guide at the front without anyone stopping. For sites that already run visits with a lead guide and a tail escort, this is probably the biggest practical gain. Walls, floors and long distances Plants are built from concrete, steel and a great deal of metal pipework, and routes can run from a control room across open yards to a turbine hall. That is hard on radio signal. It is the reason to test any system on your actual route, including the awkward parts: behind thick walls, down stairwells, along the longest stretch from the guide's position. Where the 008B fits For this kind of route, the YingMi 008B is a good candidate to put through a trial. It is a bi-directional system, so visitors and escorts can speak as well as listen. In open ground it is rated at over 280 meters, and it is designed to carry through concrete and brick, which are exactly the materials a plant is full of. Treat those figures as a starting point. A trial on your own site will tell you more than any rating, and it is worth running the trial before the first visit, not during it. Questions for your own safety team Some zones in energy facilities have restrictions on electronic equipment, particularly where flammable gas, dust or other hazards are present. Radio devices are not automatically welcome everywhere on site. Before you buy anything, ask your safety officer which areas allow wireless equipment, what approvals or certifications are required, and whether devices must be left outside certain zones. That decision belongs to the site, not the supplier, and it is worth settling before you design the route around the equipment. Counting devices in and out Controlled sites usually already count people in and out. Count the receivers the same way. A missing device on a secure site is a bigger issue than a missing device at a gift shop, and a simple tag number on each unit makes the check quick. Agree who hands them out, who collects them and who signs off at the end. FAQ Is a tour guide system suitable for a power plant tour? Yes, in areas where wireless equipment is permitted. It lets the guide be heard over machine noise, and a two-way system also lets visitors and escorts speak up. Can wireless devices be used in restricted or hazardous zones? That depends on the site's own rules and approvals. Ask your safety officer before planning a route around any equipment. Will the signal work through thick plant walls? It varies by system and layout. The 008B is designed to carry through concrete and brick, but test on your own route before relying on it.

Mostly by getting the host's voice out of the room's acoustics. With a wireless tour guide system the host speaks at a normal volume and every guest hears the same thing, whether they are standing in a marble lobby or next to a press line. That sounds like a small improvement, and it is easy to underrate. A client visit is rarely judged on the content of any one sentence. It is judged on whether the person at the back could follow along, whether the host looked relaxed, and whether the visit seemed to be under control. A host who has to raise their voice over a machine, turn back to see who is still behind them and repeat the last point for latecomers is not giving that impression, however good the company is. Walk the route before you pick anything If you are setting up a visitor center, the most useful thing you can do before comparing products is to walk a client route with a notebook. Mark where the group tends to bunch up, where the host has to talk over something, and where people drift to look at a display while the host is mid-sentence. The pattern is usually the same. The trouble is not in the quiet gallery. It sits in the transitions: the corridor between the showroom and the workshop, the moment the group crosses a loud area, the pause while someone fetches a badge. Those are the places where a voice in the ear earns its keep. In the gallery, the host could probably do without it. Hosted visits and walk-in visits need different answers A scheduled client visit has a person leading it, and the equipment should serve that person. A brand museum that opens its doors to anyone has no such person on most days. Buying one system for both and hoping it works is how centers end up with receivers in a cupboard. Decide which kind of visit matters more to you. If the answer is "both," plan two modes of working from the start, and be honest about which days will have a host and which will not. Where the E8 fits For hosted visits, we point people to the YingMi E8. It is a one-way system: the host holds a transmitter and guests wear small receivers, which weigh 18 grams. There are 150 channels, so two or three groups can be on site at once without crossing over, and the units run 7 to 10 hours between charges. Two features are worth a closer look for corporate work. The first is the main and sub dual-talk function, which lets two speakers hand over without fiddling. That suits the common arrangement of a host who knows the company and a specialist who knows the product. The second is a mode that plays pre-stored audio as well as live commentary, so a recorded introduction can run when nobody is free to give it. It is not location-triggered, so a walk-in museum that wants commentary to start itself at each display would be better served by a self-guided system. It has been used on factory tours, for instance at the Wuhan Cigarette Factory. The system comes in kits, from 20 receivers to 500, so the size of your busiest group decides which one you start with. A few things to settle before you buy Test it in the loudest part of your own route, not in the showroom. Count how many people you host at the same time on your worst day, then add some margin. Decide who sets the receivers out and collects them afterwards, because it is a job, and someone has to be named. And think about how the first minute goes: guests handed a receiver and a short word on how to wear it behave very differently from guests left to work it out. None of this is complicated. Most of it is the kind of preparation that makes a visit feel looked after. FAQ Is a tour guide system worth it for a small visitor center? If the route includes any noisy area or the groups regularly reach ten people or more, yes. For a single quiet room, probably not. Can two hosts use one system on the same visit? With the E8, yes. The main and sub dual-talk function lets a second speaker take over from the first. Does it work for visitors who arrive without a host? Only partly. The pre-stored audio mode can play recorded commentary, but it does not start itself by location. For that you want a self-guided system.

Project Background The Shanxi Fenjiu Exhibition Hall is designed to present the brand's history, culture, and development through different exhibition areas. For guided visits, visitors need to receive clear and relevant explanations as they move from one zone to another. To support this type of exhibition environment, the Shanxi Fenjiu Exhibition Hall selected the Yingmi MC200 multi-channel zone tour guide system.     The Challenge A multi-zone exhibition hall may contain different display areas, each requiring its own audio content or guided explanation. A conventional sound system can make it difficult to manage different zones, especially when several areas need to operate independently. The exhibition hall therefore needed a solution that could support zone-based audio management and smooth transitions between different exhibition areas.     The MC200 Solution Yingmi provided the MC200 multi-channel zone tour guide system for the Shanxi Fenjiu Exhibition Hall. The MC200 is designed specifically for exhibition halls and other venues where different areas require independent audio guidance. When a guided group enters a designated area, the corresponding audio channel can be activated. As the group moves between zones, the system supports automatic switching between different areas, helping maintain a smooth guided-tour experience. The system can also support pre-recorded audio content, allowing exhibition information to be prepared in advance and played according to the requirements of different zones.   Application at the Exhibition Hall At the Shanxi Fenjiu Exhibition Hall, the MC200 provides a structured way to manage audio across different exhibition areas. Instead of relying on one sound source for the entire venue, the system allows different zones to be managed separately. This helps match the audio content with the exhibits and areas being visited. For exhibition operators, this provides a more organized approach to multi-zone guided tours while reducing the difficulty of managing different areas simultaneously.   Key Benefits Multi-Zone Audio: Different exhibition areas can use independent audio channels. Automatic Zone Switching: Audio can switch between areas as visitors move through the exhibition. Reduced Interference: Separate zones can operate without unnecessary audio overlap. Pre-Recorded Content: Recorded explanations can be played in designated areas. Suitable for Group Visits: Designed for guided reception in exhibition halls and similar venues. Result By introducing the Yingmi MC200, the Shanxi Fenjiu Exhibition Hall gained a dedicated solution for managing audio across multiple exhibition zones. The system helps coordinate zone-based explanations and supports a smoother visitor experience throughout the guided tour. The project demonstrates how multi-channel zone audio technology can be applied to modern exhibition halls where different areas require independent and coordinated audio guidance.

Overview Langmusi Scenic Area in Gannan Tibetan Autonomous Prefecture, Gansu, is known for its monasteries, open grassland, mountain scenery and Tibetan culture. To help visitors get more from their time on site, the scenic area introduced a YingMi audio guide rental cabinet. Visitors can now borrow a guide device on their own, explore the attractions at their own pace, and return it when they finish.   Background Langmusi welcomes a steady flow of visitors, especially in summer and during holidays. Many travel independently or in small groups, and not everyone has a local guide. Without commentary, it is easy to walk past the stories behind the temples, traditions and landscapes. The scenic area wanted a simple way to offer quality interpretation to every visitor, without long waits at the service counter and without adding to staff workload.   The Solution YingMi provided an audio guide rental cabinet at the scenic area. The process is easy for visitors: Pick up: Visitors go to the rental cabinet and take a guide device on their own. Explore: They walk through the scenic area with the device, listening to commentary on the sites, culture and history as they go. Return: When the visit is over, they return the device to the cabinet. The cabinet also stores the devices in one place, keeping them organized and ready for the next visitor.   Benefits For visitors: Self-service access, no waiting for staff, and the freedom to tour at their own pace. Clear audio commentary helps them understand what they see. For the scenic area: Devices are stored and managed in one location, less manual work at the counter, and a more polished visitor experience. For the destination: Richer interpretation helps share the culture and heritage of Langmusi with visitors from near and far. Conclusion At Langmusi, the rental cabinet makes audio guides easy to reach for every visitor. Guests can pick up a device, tour the attractions and learn about the place they are visiting, all on their own schedule. It is a practical solution for scenic areas that want to improve the visitor experience while keeping operations simple. About YingMi YingMi, a brand of Hefei Humantek Co., Ltd., provides tour guide systems and related equipment for museums, scenic areas, factories and other venues worldwide.

About the Client Xiangyang Vocational and Technical University is a higher education institution in Xiangyang, Hubei Province, with a campus that includes teaching buildings, exhibition spaces, and areas of cultural and historical interest. As the university has expanded its visitor and orientation programs — welcoming prospective students, alumni, delegations, and members of the public — the need for a consistent, hands-free way to guide visitors through campus without relying solely on staff-led tours has grown. The Challenge Traditional campus tours depend heavily on the availability of trained guides or docents. For a university campus, this creates a few recurring pain points: Guided tours are difficult to scale during peak periods such as open days, orientation weeks, or large group visits. Visitors moving through different buildings or exhibition areas at their own pace often miss context that a live guide would normally provide. Manual, speaker-based narration can create noise interference between multiple simultaneous tour groups moving through the same spaces. The university was looking for a self-service solution that could let visitors explore campus areas independently, trigger relevant commentary automatically as they moved from one point of interest to another, and reduce dependence on live narration — all without added complexity for visitors to operate. The Solution: YingMi i7 YingMi supplied the university with its i7 Automatic Induction Guide System, a wearable, RFID-triggered self-guided tour device designed for exactly this kind of walk-and-listen experience. How it works: Visitors wear the i7 receiver as they move through campus. As they approach an RFID trigger point near a building, exhibit, or point of interest, the device automatically detects the signal and begins playing the corresponding audio commentary — no buttons to press, no manual instructions needed. As the visitor continues walking to the next point, the device seamlessly switches to the new content. Key product characteristics that made the i7 a fit for a campus environment: Automatic, hands-free triggering via RFID sensing, removing the need for staff to manually start or explain each segment of the tour. Large content capacity, supporting up to 9,999 pre-stored audio segments, which allows the university to build out detailed, multi-stop commentary across different buildings and areas over time. Multi-language support across 8 languages, useful for a university campus that receives both domestic visitors and international guests or exchange delegations. Stable, interference-resistant signal transmission, so multiple visitors or groups can move through campus simultaneously without audio overlap or dropout. Compact, lightweight wearable design, making the device comfortable for visitors during longer walking tours.     Implementation YingMi worked with the university to plan RFID trigger placement at relevant points of interest across campus and to load the corresponding narration content onto the i7 units, in line with the standard customization workflow YingMi follows for institutional clients — from requirement confirmation through sample testing and final deployment. The device's OEM/ODM flexibility also means the university retains the option to expand or adjust content, add trigger points, or customize the units further as its visitor programs evolve.     Outcome With the i7 system in place, Xiangyang Vocational and Technical University is able to offer visitors a self-guided way to explore campus, with commentary that plays automatically at the right location and moment — reducing reliance on live guides for routine tours while keeping the visitor experience informative and consistent. The multi-language capability also positions the university to better accommodate international visitors as part of its broader outreach and exchange activities. Why It Matters This deployment reflects a broader trend among educational institutions, museums, and heritage sites: moving from staff-dependent narration toward automated, location-aware guide systems that scale more easily with visitor volume. For universities in particular, a self-guided induction system like the i7 offers a practical way to support open days, orientation events, and everyday campus visits without adding administrative burden.

On October 19, 2020, Wuhan Cigarette Factory equipped its visitor reception team with the YingMi E8 wireless tour guide system, a compact team guide system built for exactly this kind of setting: a live production environment where visiting delegations need to hear a guide clearly without disrupting the surrounding operation. The deployment reflects a broader pattern across Chinese manufacturing enterprises, where wireless tour guide systems have become a standard part of hosting government inspections, corporate delegations, and industrial tourism visits.       Client Background   Wuhan Cigarette Factory is a large-scale industrial manufacturing facility that regularly hosts official inspections, corporate visits, and delegation tours through its production areas and corporate culture exhibits. Facilities of this scale routinely bring small groups of visitors through active workshops, exhibition corridors, and display walls that communicate company history, values, and operational milestones — all while production continues around them.       The Challenge   Factory floors present a difficult listening environment. Machinery noise, wide-open workshop layouts, and the need to keep visiting groups moving efficiently all work against a guide simply raising their voice. During the period of this visit, delegation members were also wearing masks, which further muffled speech and made face-to-face explanation even harder to follow. The reception team needed a way for one guide to deliver a clear, continuous explanation to a small group as they moved between exhibit panels and production line viewpoints, without visitors bunching up around the speaker to hear.         The YingMi E8 Solution   The E8 team guide system was selected for this reception because its core design matches this exact scenario: the guide holds a transmitter, each visitor wears a receiver, and the guide's explanation is delivered directly and clearly to every listener regardless of ambient noise or physical distance within range. As the delegation moved past the corporate culture display boards and along the production line viewing corridor, the guide could narrate continuously while the group maintained a natural, spread-out walking formation instead of clustering to hear.   Key Features Deployed   One-way clear-audio explanation: The transmitter-and-receiver format let the guide narrate over machinery noise while every visitor heard the explanation directly through their receiver. Ultra-light, non-intrusive wearable design: Visitors could wear receivers comfortably for the full walking tour without the device becoming a distraction. Reliable indoor range: With a communication distance of up to 200 meters, the group could spread out naturally across the wide workshop and corridor spaces without losing signal. Mask-compatible communication: Because the explanation is transmitted electronically rather than relying on projected speech, the system overcame the muffling effect of masks worn throughout the visit.     Outcome   The E8 system allowed Wuhan Cigarette Factory's reception team to guide its visiting delegation smoothly through both the corporate culture exhibit area and the live production floor in a single, uninterrupted walking tour. Visitors stayed informed and engaged at a comfortable distance from both the guide and the machinery, and the reception ran without the repeated stopping, regrouping, or raised-voice explanation that factory tours typically require. The visit became a template the reception team has continued to rely on for subsequent delegation tours through the facility.

Background Jingzhou Museum needed a way to guide multiple visitor groups through different exhibition zones at the same time, without narration from one group overlapping or interfering with another — while still allowing staff to switch flexibly between live commentary and pre-recorded audio depending on the audience. Solution YingMi supplied a multi-channel zone broadcast guiding system. Each docent wears a wireless microphone paired with a control/playback host. As the docent enters a given exhibition zone, the host automatically connects to that zone's players, so narration is heard only by visitors within the corresponding area.   Operation Docents can lead grouped tours with live, real-time commentary as they move through the museum, or switch to on-demand audio playback for self-guided segments — adapting easily to both general visitor groups and VIP delegations.     Outcome The system gave the museum a more flexible reception process for varied visitor types, while reducing the need for additional on-site staff to manage multiple simultaneous tours.
