Abstract

The utility model provides an audio processing system supporting vehicle-mounted K songs and a vehicle, wherein the audio processing system comprises an audio processor with a voice separation function, a power amplifier module and a loudspeaker, the audio processor is connected with a vehicle-mounted information entertainment system or an intelligent cabin domain controller, and a microphone is directly connected with the audio processor instead of being connected with the audio processing system after passing through the vehicle-mounted information entertainment system. Based on the structure, the transmission path of the microphone audio signal is greatly simplified, and the audio delay is effectively reduced. And after the second audio signal acquired by the microphone and the audio signal output by the vehicle-mounted information entertainment system or the intelligent cabin domain controller are processed by the audio processor with the voice separation function, the speaker is driven to sound through the power amplifier module. Therefore, dependence on external equipment such as a vehicle and a machine is reduced, system resource occupation is reduced, and human voice separation effect is improved.
