Document Type and Number:
WIPO Patent Application WO/2021/239044
Kind Code:
A1
Abstract:
A microphone system, a control method, and a vehicle. The system comprises a microphone module (10), a multimedia host (20), and a power amplifier (30), the multimedia host (20) and the power amplifier (30) are both communicatively connected to the microphone module (10), and the power amplifier (30) is further electrically connected to a loudspeaker module (40). The present system does not need to separately provide a voice microphone and a noise reduction microphone to collect voice signals and noise signals separately, and perform audio signal transmission between the microphone module (10) and the multimedia host (20), and between the microphone module (10) and the power amplifier (30) on the basis of the communication connection, which may reduce a large number of connecting wire harnesses.
