Abstract

An environmental detection sound system includes a wireless communications unit, a system chip wirelessly communicating to an external operation device; an audio compilation unit, an output unit, a detector module and a data processing unit; wherein the system chip receives a control signal and a sound source signal, converts the sound source signal to a programming audio signal and then outputs the programming audio signal; the audio compilation unit receives the programming audio signal, converts the programming audio signal to an audio signal, and then outputs the audio signal; the output unit receives and plays back the audio signal; the detector module detects an environment and outputs a detection value; the data processing unit receives the detection value and produces a warning audio and a warning message to remind listeners to timely improve environmental conditions when the detection value exceeds a standard value, so as to maintain safety and health.

Claims
