Mobile Public Toilet Broadcast Playback

Mobile public toilets can achieve broadcast playback by adding voice prompt functions. A common solution includes the human body induction voice prompt device developed by Wichip, which supports two effects: advertising and civilized prompts.

Implementation Methods for Advertising and Civilized Prompts

The voice prompt function of mobile public toilets can achieve two types of effects by playing preset audio:

1. Civilized Prompts: For example, playing "XX Environmental Protection reminds you to put garbage in the bin" to guide users to regulate their behavior and improve public hygiene standards.
2. Advertising: Commercial advertisements or public service announcements can be played. However, it is important to note that the audio content should comply with public place regulations to avoid excessive commercialization that may cause user aversion.

Hardware Devices and Functional Features

Wichip provides two mainstream devices to support broadcast playback:

1. Automatic Induction Player (isound)

   • Induction Trigger: Through human body induction technology, it automatically plays voice prompts when users approach, without the need for manual operation.
   • Audio Format: Supports MP3 format, making voice updates convenient. Content can be quickly adjusted by replacing audio files.
   • Device Linkage: It can be connected to the lights, exhaust fans, and other devices in the public toilet to achieve the function of "induction playback of voice prompts + simultaneous activation of devices". For example, after triggering the induction, it plays a prompt sound and turns on the exhaust system.

2. Timed Induction Player (KingSound)

   • Precise Induction: It uses a pyroelectric sensor to identify when someone passes by and plays a prompt sound, avoiding false triggers.
   • Timing Function: It has a built-in WiFi module and can set playback times through a mobile app, such as playing civilized prompts cyclically during peak hours.
   • Multi-device Connection: It supports linkage with lights, exhaust fans, or counters. For example, it can play a "Welcome to use" prompt sound when counting the number of people.

Application Scenarios and Advantages

The broadcast playback function of mobile public toilets is suitable for high-traffic areas such as scenic spots and transportation hubs. Its advantages include:

• Enhancing User Experience: Voice guidance reduces user confusion in operations, such as prompting "Door unlocked" or "Please save water".
• Reducing Management Costs: Automated playback reduces the need for manual inspections and generates additional revenue through advertising.
• Environmental Education: Repeatedly playing environmental protection prompts can subtly cultivate users' civilized habits and assist in public hygiene management.
