| Zusammenfassung: | The utility model discloses a multi-sound-source bus audio processing system which comprises a CPU, a multi-sound-source voice system, a path switch and a loudspeaker. The cpu is used for controlling a working process and processing a digital audio file and issuing a broadcast instruction to the multi-sound-source voice system, the multi-sound-source voice system is connected with the path switch, path switching of the multi-sound-source voice system during multiplexing of a hardware circuit is realized through the path switch, and after audio signal amplification and audio power amplification, the multi-sound-source voice system sends the broadcast instruction to the multi-sound-source voice system. Through the application of the path switch, path management is carried out on the audio processing circuit, and multiplexing of the signal processing circuit and the power amplifier circuit is realized, so that the scale of the audio processing circuit is reduced, the hardware cost of the audio processing circuit |
