Yingmi offers customized solutions for all scenarios

Riding instruction happens at a distance, outdoors, and hands-free — conditions that rule out a standard one-way tour guide system and call for something built to let riders talk back. An equestrian training tour guide system solves a communication problem that's specific to the riding arena: an instructor standing in the center of a ring, or moving along a track, needs to correct and coach several riders spread out across open ground — often while horses are moving, wind is present, and every rider needs both hands on the reins rather than holding a phone or radio. A standard tour guide system, built for one narrator broadcasting to a group, only solves half of that problem. Why One-Way Systems Fall Short for Riding Instruction Most tour guide systems are one-way by design: a guide speaks, a group of receivers listens. That works well for a museum tour or a factory visit, where the audience mainly needs to hear an explanation. Riding instruction is different — it's a back-and-forth exchange. A rider needs to ask a question or report what they're feeling in the saddle, and the instructor's response needs to reach not just that rider but the rest of the group, since the correction is often useful to everyone training at the same time. A one-way system forces the instructor to shout across the arena to hear a rider's question, then repeat the answer to the group manually — exactly the kind of disruption an audio guide system is supposed to eliminate. How a Bi-Directional System Changes the Setup This is where a bi-directional tour guide system fits the equestrian setting specifically. The  008B, a wireless bi-directional tour guide system, is built around exactly this kind of two-way interaction: any rider wearing a receiver can speak up and be heard by the instructor and the rest of the group, not just receive one-way narration. Standard One-Way System 008B Bi-Directional System Instructor speaks, riders listen only Any rider can speak and be heard by the whole group Questions require shouting across the arena "Ask one, answer heard by everyone" interaction built in Fine for narration-only settings Built for coaching, training, and Q&A-style instruction Why Range and Signal Strength Matter More Outdoors Riding arenas and training fields are open, outdoor spaces — often larger than the indoor venues most tour guide systems are designed around, and without walls to help contain a signal. The 008B tour guide system is rated for an open-field transmission distance of 280 meters or more, which covers the kind of spread-out group a mounted training session typically involves, and its signal is built to penetrate obstacles like concrete and brick walls for the times training moves between an outdoor ring and an indoor arena. Setting Up for a Training Session A typical equestrian training setup pairs one transmitter with the instructor and a receiver for each rider. Because riders need both hands free, the transmitter is usually worn rather than hand-held, leaving the instructor free to demonstrate or move around the arena while still narrating and receiving questions from riders in real time. Instructor wears the transmitter, hands-free, to allow for demonstration and movement around the ring Each rider wears a receiver capable of two-way communication, not just listening Devices are paired before the session begins, since interrupting a lesson mid-session to fix a connection isn't practical once riders are mounted Where This Extends Beyond Riding Lessons The same bi-directional setup used for equestrian training applies to any coaching or instructional setting where participants need to talk back, not just listen — outdoor sports training, guided fieldwork, or technical instruction where trainees need to report what they're seeing or feeling in real time rather than wait until the session ends to ask. Frequently Asked Questions Can all riders talk at once, or only one at a time? The system is built around one rider asking and everyone hearing the answer — it's designed for structured back-and-forth rather than an open channel where everyone speaks simultaneously. Does the range hold up across a full-size outdoor riding arena? An open-field range of 280 meters or more comfortably covers most riding arenas and training fields, though it's worth confirming with the vendor for unusually large properties. Is a bi-directional system harder for riders to operate than a standard receiver? Not meaningfully — riders typically just wear the receiver and speak when needed, without additional controls to manage while their hands are occupied with the reins. Can the same equipment be used for group lessons and one-on-one coaching? Yes — a bi-directional system works for both, since it supports a single rider communicating with the instructor just as easily as a full group session.

Open days and orientation weeks put university campus tours under a kind of pressure a small, staff-led group never faces. Audio guide systems are how a growing number of universities keep those tours coherent at scale. University campus tours for prospective student groups create a scheduling and logistics problem that most other guided-tour settings don't have to solve. A single open day can bring in dozens of visitor groups moving through the same buildings within a few hours, and an audio guide system built for university campus tours is often what keeps that many groups moving without the whole visit collapsing into noise and confusion. Why Large Prospective Student Groups Strain Traditional Campus Tours A campus tour built around one staff guide speaking to one group works fine most of the year. It breaks down during peak recruitment periods, when several groups need to move through the same teaching buildings, labs, and exhibition spaces at overlapping times. A few problems show up consistently: Guide availability becomes the bottleneck — there are only so many trained staff who can lead a polished tour at once. Multiple groups moving through the same corridors and lobbies create overlapping voices and noise interference. Visitors at the back of a large group often miss details that a smaller, closer group would hear clearly. Staff-led tours are hard to scale without proportionally scaling staff hours, which most admissions offices can't do just for a handful of peak dates a year. What to Look for in a Campus Tour Audio Guide System Not every audio guide system is built for the specific demands of a university campus. A few features matter more here than in a standard conference or exhibition setting: Self-guided, automatic playback — so content plays without a staff member needing to narrate every stop in real time. Enough stored content capacity to cover a full campus — multiple buildings, labs, and points of interest — without needing to reload devices between tours. Multi-language support, since university visitors increasingly include international applicants, exchange delegations, and visiting families. Interference-resistant signal transmission, so several groups moving through the same buildings at once don't experience audio overlap. Lightweight, comfortable wearable design, since campus tours often involve more walking and a longer duration than a typical indoor exhibition tour. Case in Point Xiangyang Vocational and Technical University Adopts the YingMi i7 Facing the same scaling problem during open days and orientation weeks, Xiangyang Vocational and Technical University in Hubei Province deployed the YingMi i7 Automatic Induction Audio Guide System — a wearable, RFID-triggered device that plays the right commentary automatically as visitors approach each building or point of interest. With support for up to 9,999 stored audio segments and 8 languages, plus interference-resistant transmission that lets multiple groups move through campus at once, the university reduced its reliance on live guides for routine tours while keeping the visitor experience consistent. Self-Guided vs. Staff-Led: Finding the Right Mix Most universities don't need to choose one model exclusively — the more common approach is using each where it fits best. Approach Works Best For Self-Guided Audio System High-volume periods like open days, orientation week, and walk-in visitors exploring at their own pace Staff-Led Tour Smaller, high-touch visits such as VIP delegations or applicants with specific questions Planning for Peak Periods The real test of a campus tour audio guide system isn't a quiet Tuesday afternoon — it's an open day with a dozen simultaneous groups. Universities getting the most out of these systems tend to plan trigger points and content well ahead of peak dates, confirm how many groups the system can support running at once without interference, and keep a buffer of spare, charged units on hand for unexpected turnout. Frequently Asked Questions Can one audio guide system really support multiple simultaneous tour groups without interference? Yes, provided the system is specifically built with interference-resistant signal transmission. It's worth confirming with the vendor how many concurrent groups the system has actually been tested to support. How much content should a university load before launching a self-guided tour system? This depends on how many buildings and points of interest are included, but systems with large content capacity give universities room to expand commentary over time rather than needing to plan the full tour upfront. Is multi-language support worth the added cost for a domestic university campus? For universities with growing international outreach or exchange programs, it's increasingly a practical requirement rather than a nice-to-have, even if most visitors are currently domestic. Does switching to a self-guided system eliminate the need for staff during open days? Not entirely — most universities still keep staff available for questions and smaller high-touch visits, but a self-guided system significantly reduces how many staff-led tours are needed to cover peak volume.

When a fleet of audio guide devices needs to turn around between back-to-back rentals, charging speed stops being a convenience feature and becomes an operational requirement. Overnight Turnaround Window Used by Charging ~5h Standard Charging Eats into most of a typical overnight window before the next rental ~2.5h Fast Charging Leaves meaningful buffer for inspection, cleaning, and repacking High-volume corporate rentals put a fleet of audio guide devices through a punishing schedule: an event ends late, units get collected, and the same fleet needs to be fully charged and ready for a different client the next morning. Fast charging isn't a nice-to-have for this kind of turnaround — it's often the deciding factor in whether a rental business can even accept back-to-back bookings. The Turnaround Problem High-Volume Rentals Create A single device charging slowly is a minor inconvenience. A fleet of a hundred devices charging slowly is a scheduling constraint that limits how many bookings a rental operation can realistically take in a given week. Standard charging speeds that seem reasonable for occasional personal use become a genuine operational bottleneck once devices are cycling through multiple rentals per week. Why the Difference Compounds at Scale The gap between standard and fast charging looks modest for one device — an hour or two — but it multiplies across an entire fleet and across a full charging cycle: Overnight turnaround windows are fixed, regardless of fleet size, so slower charging directly reduces the time available for cleaning, inspection, and repacking Back-to-back bookings become harder to accept when charging alone consumes most of the available window between events Partial charging becomes more common under time pressure, increasing the risk of a device running low mid-event   For rental operations specifically, charging speed isn't just about device convenience — it directly determines how many events a fleet can realistically support per week. What to Look for in Fast-Charging Equipment Not all "fast charging" claims translate to a meaningful difference in a high-volume rental context. A few things are worth confirming directly with a vendor: Actual charge time from empty to full, not just a marketing label of "fast charging" Compatibility with multi-slot charging docks or boxes, since fast charging matters less if only one device can charge at a time Charging port standard — widely available connectors like USB-C simplify replacing damaged charging cables during high-volume use Heat management during rapid charging, since excessive heat over repeated fast-charge cycles can shorten battery lifespan Planning Rental Schedules Around Charging Windows Rental operations that build their booking schedule around actual charging time — rather than an idealized turnaround — tend to avoid the scramble of partially charged devices going out the door. Knowing your fleet's real charging window, including the connectors and infrastructure available. and building in a buffer beyond that time is a simple planning habit that prevents avoidable failures during back-to-back events. Frequently Asked Questions Does fast charging shorten a battery's overall lifespan? It can, depending on how heat is managed during the charging process. Ask vendors specifically about thermal management and long-term battery testing rather than assuming all fast-charging implementations are equal. Is it better to invest in more charging docks or faster-charging devices? Ideally both — more simultaneous charging slots reduce bottlenecks, and faster per-device charging reduces the total time needed even with adequate dock capacity. For most fleets, dock capacity tends to be the first constraint worth solving. How much charging buffer should a rental schedule build in? Beyond the rated charging time, building in an extra hour or two as buffer helps absorb late collections or unexpected delays without risking partially charged devices going out to the next event. Does charging speed matter as much for owned fleets as rental businesses? It matters for both, but the pressure is often higher for rental operations running frequent back-to-back bookings, where the turnaround window is tighter than for an organization managing its own occasional events.

Owning a fleet of audio guide devices creates a different challenge than buying them: keeping dozens or hundreds of units charged, clean, tracked, and ready — event after event. Managing a fleet of audio guide devices for recurring events is a fundamentally different challenge than choosing which system to buy. The purchase decision happens once. Fleet management happens every single time you run an event — and it's where a lot of organizations that made a smart buying decision still end up frustrated, because nobody planned for what happens between events. Why Fleet Management Is a Different Problem Than Buying Equipment A single device is easy to manage. A fleet of audio guide devices — 30, 100, or 200 units moving through repeated cycles of distribution, collection, charging, and storage — introduces operational complexity that has nothing to do with the equipment's original spec sheet. This is the part of ownership that buying guides rarely cover, and it's often where the real cost of managing a wireless tour guide system fleet shows up. The Operational Cycle, Not a One-Time Setup Every event puts a fleet of audio guide devices through the same recurring cycle: devices are received and inspected, assigned and distributed to attendees or staff, collected and reconciled against the count at the end, sanitized and checked for damage, recharged, and stored ready for the next event. Treating this as a recurring cycle — rather than a one-time setup you complete after purchase — is the mental shift that makes the rest of fleet management manageable. Each stage has its own failure points worth planning around. Charging Management at Scale Charging a fleet of audio guide devices one at a time is one of the most common bottlenecks organizations run into after moving from renting to owning. Dedicated charging infrastructure — multi-slot docks or charging boxes sized to your fleet — turns what would be a manual, hours-long task into a single overnight step. 10–50Devices per charging box (typical) ~2.5 hrsTypical full recharge time 6–8 hrsTypical working time per charge Systems like the YingMi L8 are sold in kits that bundle multi-slot charging boxes matched to fleet size — a 50-person kit, for example, ships with a 50-slot charging box rather than leaving organizations to source charging infrastructure separately. Inventory Tracking Knowing exactly how many devices are in circulation, how many are in repair, and how many were lost at the last event is a basic requirement for managing a fleet of audio guide devices responsibly. Even a simple spreadsheet tracking device IDs against event dates is far better than relying on memory or a rough headcount at the end of the night. Distribution and Collection Workflow The moments with the highest risk of losing track of equipment are check-in and check-out — attendees arriving in a rush, or leaving before staff can properly collect devices. A clear, fast distribution and collection process, staffed adequately for your group size, prevents the slow leak of missing units that adds up across a year of recurring events. Assign a dedicated staff member or station specifically for device handoff and return, separate from general registration Use a simple numbered or tagged system so missing units are identifiable, not just an approximate count Build in a buffer of spare charged units to cover last-minute attendance increases without disrupting the collection process Wear and Replacement Planning Certain components wear out well before the core electronics fail — earpads, lanyards, charging cables, and connector ports see the most physical handling across repeated events. Organizations managing a fleet long-term generally do better keeping a small stock of these wear parts on hand rather than discovering a shortage mid-event. Most fleet management failures aren't dramatic equipment breakdowns — they're a slow accumulation of small gaps: a missing charging cable, an uncollected receiver, a spreadsheet nobody updated after the last event. Common Fleet Management Mistakes No single owner — when fleet management is everyone's job informally, it often becomes no one's job in practice No standardized process — improvising a slightly different check-in and check-out routine at every event increases the chance of losing track of units Mixed device models — accumulating equipment from different purchases over time complicates charging, storage, and staff training A Simple Fleet Management Maturity Check If your organization can answer, within a few minutes, exactly how many devices are in the fleet, how many are currently charged and ready, and how many are out for repair — your process is in reasonably good shape. If that answer requires checking multiple people or guessing, it's a sign your fleet of audio guide devices has outgrown an informal management approach and would benefit from a documented process built around the cycle above. Frequently Asked Questions Do we need dedicated software to manage a fleet of audio guide devices? Not necessarily at smaller scale — a well-maintained spreadsheet can work for fleets of a few dozen units. Larger fleets across frequent events may benefit from dedicated inventory tracking, but it's not a requirement to get started. How often should devices be inspected for wear or damage? A quick inspection at the collection stage after every event catches most issues early. A more thorough check of wear parts like earpads and cables on a quarterly basis is a reasonable baseline for frequently used fleets. What's a reasonable buffer of spare units to keep on hand? This varies by event size and attendance predictability, but keeping some charged spares beyond your confirmed headcount helps absorb last-minute increases without disrupting distribution. Is it worth assigning one person to own fleet management full-time? For organizations running frequent events, having a clear owner — even as part of a broader role — tends to prevent the small gaps that accumulate when fleet management is left informal.

Reliability testing is what stands between a wireless tour guide system that performs well on a bench and one that survives a hundred real events. Here's what that testing pipeline typically involves. A Typical Reliability Testing Pipeline 01 Component Inspection Incoming parts checked before assembly begins   02 Burn-In Testing Units run continuously to surface early failures   03 Signal & Range Testing Communication distance verified under interference   04 Environmental Stress Temperature, humidity, and drop testing   05 Battery Cycle Testing Repeated charge cycles verify claimed lifespan   06 Final QC Audit Finished units sampled against spec before packaging Reliability testing rarely gets mentioned in a product brochure, but it's arguably the single biggest factor separating a wireless tour guide system that holds up across a hundred events from one that starts failing after a dozen. Before any audio guide system reaches a buyer, a well-run manufacturing process puts it through a series of checkpoints designed to catch problems long before they show up at a client's event. Understanding what that testing pipeline typically looks like helps buyers ask sharper questions — and spot the difference between a vendor who takes reliability seriously and one who treats it as an afterthought. Why Reliability Testing Matters More for Equipment Used at Scale A single defective unit is a minor annoyance for personal electronics. For an organization deploying dozens or hundreds of devices across recurring events, a defect rate that seems small in percentage terms can translate into a meaningful number of failed units showing up exactly when they're least convenient — mid-conference, mid-tour, in front of a client or delegation. This is why reliability testing at the manufacturing level matters more for B2B audio guide equipment than it might for a single consumer gadget. Walking Through the Testing Pipeline While specific processes vary by manufacturer, a thorough reliability testing pipeline for wireless tour guide equipment generally covers six stages: 1. Component Inspection Before assembly even begins, incoming components — circuit boards, batteries, housings, connectors — are checked against specification. Catching a defective batch of components here is far cheaper than discovering the same defect in a finished, assembled unit. 2. Burn-In Testing Assembled units are run continuously for an extended period before shipping. Burn-in testing is designed to surface early-life failures — the small percentage of units with a manufacturing defect that would otherwise fail within the first weeks of real use, ideally catching them on the factory floor instead of at a customer's event. 3. Signal and Range Testing Each unit, or a representative sample, is tested for communication range and stability, often under conditions designed to simulate interference from other wireless devices. This stage verifies that the signal performance claimed on a spec sheet actually holds up rather than reflecting only ideal lab conditions. 4. Environmental Stress Testing Equipment gets tested against temperature extremes, humidity, and physical stress like drops or vibration — conditions that mirror what devices actually experience during shipping, storage, and repeated handling across many events and users. 5. Battery Cycle Testing Batteries are put through repeated charge-and-discharge cycles to verify that claimed battery life holds up not just on a single charge, but across the hundreds of charge cycles a device will experience over its working life. 6. Final QC Audit Before packaging, finished units are sampled and checked against the full specification one more time — a final gate designed to catch anything that slipped through earlier stages before the product reaches a buyer. None of these stages guarantee zero defects. What they do is shift failures from a client's event to the factory floor, where they're cheaper to catch and far less disruptive to fix. What Buyers Should Ask Vendors to Confirm Most reliability testing happens out of view, which means buyers generally have to ask direct questions rather than relying on marketing language alone: What does burn-in testing look like, and how long does it run before units ship? Is signal and range performance tested under interference, or only in ideal conditions? What environmental conditions are units tested against before shipping? How is battery life verified — a single test cycle, or repeated cycles over time? What does the final QC sampling process check before packaging? A Note on Certification vs. Internal Testing Internal reliability testing and third-party certification are related but different things. Internal testing reflects a manufacturer's own quality process, while certifications from independent bodies verify compliance with specific external standards. A vendor with strong internal testing may or may not hold every certification relevant to your market — it's worth asking about both separately rather than assuming one implies the other. Why Skipping This Step Costs More Later Cutting corners on reliability testing lowers manufacturing cost in the short term, but the expense typically resurfaces later — as warranty claims, damaged client relationships, and equipment failures that happen at the worst possible moment. For B2B buyers evaluating vendors, asking about the reliability testing process isn't a minor technical question. It's a reasonable proxy for how seriously a manufacturer takes the equipment holding up after the sale is complete. Frequently Asked Questions Does every manufacturer follow the same reliability testing process? No — testing rigor varies significantly between manufacturers. It's worth asking vendors directly about their specific process rather than assuming a standard applies industry-wide. How long does burn-in testing typically run? Duration varies by manufacturer and product complexity. Rather than assuming a specific number of hours, ask the vendor directly what their burn-in process involves. Is reliability testing the same thing as a product warranty? No — reliability testing happens before a product ships and is designed to catch defects early. A warranty is a separate commitment covering issues that arise after the sale, during the ownership period. Can buyers request evidence of a vendor's testing process? Many vendors can share testing documentation or summary reports on request, particularly for larger orders. It's a reasonable question to ask before committing to a bulk purchase.

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.  

Project Overview In December 2024, YingMi successfully provided and deployed the R8 wireless tour guide equipment for Gravity Aircraft Industry (Hefei) Co., Ltd., a professional enterprise engaged in aircraft industry research, manufacturing and related business services.

In September 2023, to optimize the cultural tourism service experience and improve the smart tourism infrastructure of Hangnan Village, YingMi customized and officially deployed the 007B Self-guided Audio Guide System tailored to the actual sightseeing needs of Hangnan Village scenic area.   Previously, the traditional tourism service model of Hangnan Village faced multiple pain points, including limited coverage of manual tour explanations, inconsistent visitor experience, and high labor costs for scenic area operation, which could not meet the growing demand for independent, intelligent and convenient cultural tourism travel. The newly launched 007B Self-guided Audio Guide System is perfectly adapted to rural scenic scenarios with simple operation and stable performance. Visitors can automatically trigger audio explanations and obtain detailed scenic spot introductions, local cultural stories and travel guidance on demand without manual tour guides.   The official operation of the system has effectively improved the smart cultural tourism service capacity of Hangnan Village and greatly enhanced the independent travel experience of tourists, while reducing the daily operation labor cost of the scenic area. Meanwhile, the system helps spread the unique regional culture and rural characteristics of Hangnan Village in a standardized and systematic manner. It supports the scenic area in building a standardized, intelligent and high-quality rural cultural tourism service system, laying a solid foundation for the quality improvement, efficiency enhancement and digital upgrading of local rural cultural tourism.
