Description

200541307 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention "the mobile phone incoming call sensing structure of audio-visual audio equipment" mainly relates to a method for automatically sensing and audio-visual when a mobile phone needs to be answered or dialed Innovative structure for audio equipment that is turned off or muted to facilitate the use of mobile phones. [Previous technology] With the rapid development of technology and the improvement of living standards, mobile phones have become an indispensable portable device for modern people. However, when using a mobile phone in a car, audio-visual audio equipment is commonly installed in the car. Therefore, when using a mobile phone in the car, the audio-visual audio equipment must be turned off or turned down before the call can be clearly received and spoken. However, as far as the driver of the car is concerned, whether it is his own mobile phone or the mobile phone of a fellow passenger who wants to use it, the driver must perform the action of turning off the audiovisual equipment, so that it may cause a traffic accident due to distraction. , Quite dangerous. Although there is a pre-patent case, a speakerphone device for automobiles is proposed, which connects a mobile phone to audiovisual equipment through a signal cable. However, this conventional device has the following defects: 1. The signal line of the handset device is connected to the driver's mobile phone, which is not convenient to use. 2. This type of speakerphone device can only provide driver's mobile phone connection. Its main function is to amplify the sound. In fact, it is still impossible to avoid the lack of interference in the sigma concert. 3. Even if the hands-free handset device is installed on the car,
