The invention discloses a system for multiplexing a loudspeaker and a microphone and a cabin, which are applied to a vehicle. The system comprises a microphone configured to collect sound signals in a vehicle; a loudspeaker configured to play audio; a plurality of communication controllers configured to generate a demand instruction; and the cabin controller communicates with the microphone, the loudspeaker and the plurality of communication controllers, the cabin controller is connected with the plurality of communication controllers through an automobile audio bus, and the cabin controller is configured to receive demand instructions sent by the plurality of communication controllers and manage and drive the microphone and/or the loudspeaker according to the demand instructions. According to the application, the multiplexing of the analog microphone and the loudspeaker in the vehicle can be realized through the vehicle audio bus, the utilization rate of the microphone and the loudspeaker in the vehicle is improved, and the cost is reduced.
