Abstract

The invention provides a vehicle-mounted audio processing device which comprises an audio input device and an audio output device. The audio input device is connected to a loudspeaker through an audio amplifying circuit, the loudspeaker outputs received voice signals of another terminal equipment to a user, and the audio output device receives voice signals of the user and transmits the voice signals to another terminal equipment through a mobile communication network. Power compensation is performed on audio signals input to the audio input device through a compensation circuit, and volume of the loudspeaker is adjusted automatically according to volume difference value received and output audio signals, so that calling experience of the user is enabled to be comfortable; setting of volume buttons is omitted, so that compactness and attractiveness of a cellphone are further improved; audio signals of a main MIC and an auxiliary MIC are amplified and attenuated through a filter and optimization module, so that transmissivity of environment noise is lowered greatly, and listening experience of the user is improved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a vehicle audio processing device. Background technique [0002] Looking forward to the development of automotive electronics technology, modern automotive electronics has entered a new stage of substantial improvement from the electronic components used to the architecture of the electronic system in the car.
