Abstract

The invention discloses an in-vehicle call communication compensation device and method, and the device comprises a vehicle machine system which is used for collecting a vehicle machine state signal of a vehicle; a plurality of microphones and a plurality of loudspeakers; the external power amplifier assembly is respectively connected with the vehicle machine system, the microphone and the loudspeaker, and is used for receiving a vehicle machine state signal of the vehicle machine system and an audio signal acquired by the microphone, processing the audio signal according to the vehicle machine state signal, and sending the processed audio signal to the loudspeaker; and sending the processed audio signal to a loudspeaker at a preset position according to the position of the microphone for acquiring the audio signal. According to the invention, the microphone is adopted to collect the speaking sound of a certain passenger, then the speaking sound of the passenger is processed by the external power amplifier assembly, the speaking sound of the passenger is amplified, and then the loudspeaker in the vehicle is driven to play back, so that other passengers can clearly hear the speaking sound of the passenger, and a good communication environment in the vehicle is realized.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more particularly relates to a device and a method for compensation of in-vehicle communication communication. Background technique [0002] When the vehicle is running, the driver turns his head from time to time to talk to the rear passengers, or the rear passengers basically rely on "shouting" when they are not "gentlemen". These are unsafe and unfriendly driving experiences. In high-speed and noisy scenarios, adding the function of active in-vehicle communication compensation can help people in the car to communicate in a convenient language and enjoy a comfortable and comfortable driving journey. [0003] Chinese patent CN202021040629.6 discloses a speaker with sound quality compensation, including a speaker composed of a speaker skeleton, a circuit board and a voice coil. The integrated inductive coil made of tube, one group of inductive coils of the inductive coil is driven by ano...
