Abstract

차량에 장착된 오디오용 스피커를 이용함으로써, 핸드폰용 스피커의 추가장착없이도, 핸드프리기능의 핸드폰의 기능을 수행할 수 있도록 하여, 핸드폰의 차량설치 비용을 절약할 수 있고, 차량 내부의 공간활용에 일조 할 수 있도록 하는데 그 목적이 있다.By using the audio speaker installed in the vehicle, it is possible to perform the function of the mobile phone of the hands-free function without additional installation of the speaker for the mobile phone, thereby saving the vehicle installation cost of the mobile phone and using the space inside the vehicle. Its purpose is to help them.

일측이 접지된 전자제어 유닛(25)의 타측에 오디오용 전원(B+)이 연결되고, 상기의 전자제어 유닛(25)의 출력(70)이 일측이 접지된 릴레이(20)의 각 코일(L₁, L₂)타측에 연결되고, 상기 릴레이(20)의 각가동접점(a, b)에 스피커(30) 양단이 연결되고, 상기 릴레이(20)의 고정접점(b,e)에 각각 오디오 스피커라인(40)이 연결되고, 상기 릴레이(20)의 고정접점(c,f)에 각각 핸드폰 스피커라인(50)이 연결되어지며, 상기 핸드폰 스피커라인(50)이 전자제어 유닛(25)의 작동시그날로 이용되는 시그날라인(60)이 구성되며, 상기 전자제어 유닛(25)은 검출부(A)와 작동부(B) 그리고 릴레이출력부(C)로 형성되어지는 구성이다.Audio coil B + is connected to the other side of the electronic control unit 25 having one side grounded, and each coil L of the relay 20 in which the output 70 of the electronic control unit 25 has one side grounded. ₁ , L ₂ ) are connected to the other side, and both ends of the speaker 30 are connected to each of the movable contacts a and b of the relay 20, and audio is fixed to the fixed contacts b and e of the relay 20, respectively. The speaker line 40 is connected, the mobile phone speaker line 50 is connected to the fixed contact (c, f) of the relay 20, respectively, the mobile phone speaker line 50 of the electronic control unit 25 The signal line 60 used as an operation signal is configured, and the electronic control unit 25 is configured to include a detection unit A, an operation unit B, and a relay output unit C.
