Description
Technical field
The present invention relates to the device of automatic turn-off audio when income of mobile phone in a kind of car.
Background technology
Present popularizing along with car, driving the driver all likes opening automobile audio, listen to the music or broadcast listening, if drive driver or travelling people person's cell phone incoming call this moment, listen mobile phone in order not influence, the driver will close automobile audio or volume be turned down, at this moment all can cause the driver to divert one's attention, influence attentiveness, traffic accident takes place easily.
Summary of the invention
The purpose of this invention is to provide a kind ofly in car, answer, the device of closing automobile sound equipment automatically when dialing mobile phone.
The objective of the invention is to realize in the following way: a kind of in car the device of automatic turn-off audio when income of mobile phone, on frequency selection circuit, be connected to the mobile phone signal reception antenna, frequency selection circuit connects delay trigger circuit by a diode, delay trigger circuit connects delay extinction circuit, delay extinction circuit connects Darlington circuit, Darlington circuit connects the automobile audio power supply, connects the 12V power supply at Darlington circuit.
Delay extinction circuit connects relay, and relay connects the automobile audio power supply.
Darlington circuit connects the automobile audio mute circuit.
Relay connects the automobile audio mute circuit.
The present invention has following beneficial effect, no matter be the driver or by bus personnel in car, answer or dial mobile phone, just closing automobile sound equipment does not automatically need divert one's attention closing automobile sound equipment or volume turned down of driver, guarantee that the driver can attentively drive a car, reduce the generation of traffic accident.
