top How It Works / Product Technologyindustries
 

The system operates on localized proximity triggering and reliable wireless audio transmission:

Trigger Proximity

Fixed indoor beacons (Infrared or low-power RF) emit short-range location identification signals as visitors approach an exhibit.

Auto-Switching

The receiver decodes the trigger signal within 0.1 seconds and automatically switches to the corresponding pre-recorded commentary track.

Audio Codec & Stream

Supports high-clarity audio formats (MP3, WAV up to 320kbps) delivered via standard 3.5mm stereo headphone jacks.

Signal Stability

Utilizes 2.4 GHz ISM frequency hopping to maintain reliable, interference-free audio streaming in crowded galleries with heavy visitor footfall.

audio guide

 

 

Visitors can automatically trigger the built-in audio commentary of the device via RFID induction when approaching exhibition spots. Visitors are free to switch to their preferred commentary language for audio playback, enabling a personalized visiting experience. The device is preloaded with multilingual voice packages covering major mainstream languages such as English, French and German, meeting the needs of both domestic and foreign visitors. All audio commentary content is locally stored in the automatic audio guide device. Once the device receives signals from scenic and exhibition spots, the commentary will play seamlessly and instantly with smooth performance, no stuttering, interruption or delay.

A: It is widely applicable to museums, art galleries, factories, scenic spots, corporate exhibition halls, study tours and other scenarios.

Q: Is the device easy to operate for the elderly and children?

A: Yes. It adopts automatic induction triggering, no complicated buttons, and can be used easily by people of all ages without learning costs.

Q: How many languages does the device support?

A: It is preloaded with multiple mainstream languages, including English, French, German, Spanish, Arabic, etc., to meet the needs of domestic and foreign visitors.

Q: How does the automatic audio guide trigger the commentary?

A: It triggers automatically via RFID induction when visitors approach exhibition or scenic spots, no manual operation is required.

Q: What is the battery degradation rate, and are replacement cells available?

A: The integrated Lithium-Polymer cells retain >= 80% of their initial capacity after 500 complete charge-discharge cycles (approx. 3 to 4 years of normal daily operation). Replacement battery modules are designed for easy servicing using standard internal fasteners.

Q: How does the system prevent signal interference in crowded exhibition halls?

A: The system utilizes ISM-band frequency hopping spread spectrum (FHSS) technology, automatically shifting channels to bypass Wi-Fi and Bluetooth interference generated by visitor smartphones.

Q: Can administrators update audio files without returning the physical hardware?

A: Yes. Content updates are managed via PC CMS software. Connecting the charging case via Ethernet or USB allows simultaneous batch updating of audio files across all docked receivers in under 10 minutes.

Q: What is the boundary accuracy of the auto-trigger function?

A: Infrared beacons offer strict line-of-sight triggering accurate to 1.5 meters, preventing audio crossover between adjacent exhibits. RFID/Beacon units can be software-adjusted from 1 to 10 meters.

Q: Are the multi-slot charging cases safe for unattended overnight operation?

A: Yes. Charging cases feature integrated power distribution boards equipped with short-circuit protection, over-current cutoffs, and individual thermal fuses for every charging slot.

Q: What is the standard lead time for bulk orders and OEM customization?

A: Standard stock configurations ship within 7 to 10 business days for orders under 1,000 units. OEM/ODM projects requiring custom housing colors or firmware modifications require 30 to 45 days following sample approval.
