Abstract

The invention discloses an automobile audio wireless automatic switching control system and a method thereof. The switching control system comprises a sound source signal wireless transmission module (1) and an automobile audio switching control module (2), wherein, the sound source signal wireless transmission module (1) is used for sending out an ASK code signal from an external sound source signal through an automobile horn, and carrying out carrier wave time-sharing modulation for the sound source signal and the ASK code signal in the same wireless transmission channel and carrying out wireless transmission; the automobile audio switching control module (2) is connected with the sound source signal wireless transmission module (1) in a wireless manner and arranged between an automobile audio and the automobile horn for receiving the ASK code signal and the sound source signal and controlling automatic switching of a voice-frequency channel of the automobile horn between the automobile audio and the automobile horn switching control module in accordance with the ASK code signal so as to broadcast the sound source signal from the automobile horn. The invention provides a solution scheme shared with the automobile horn and is convenient and practical.

Description

technical field [0001] The invention relates to car audio playback control, in particular to a control system for realizing wireless automatic switching of car audio and a corresponding control method. Background technique [0002] With the gradual popularization of automobiles in the Chinese market and the development of information technology, people's audio applications inside automobiles have also become more abundant. Car drivers can easily switch between car radios, CDs, VCDs, DVDs, mobile TVs, navigation devices, etc. while driving, and output audio through car speakers. Therefore, car speakers become a pronunciation resource that needs to be shared by various information network devices Or high-quality sound transmission equipment. [0003] The existing car horn is directly connected with the car audio equipment, which is the exclusive resource of the car audio. Therefore, realizing the switching control and sharing of car stereos and speakers has become a common r...
