Abstract

본 발명의 차량용 스피커를 이용한 카폰수신음 청취장치에 관한 것으로 차량용 오디오의 뮤트제어용 마이컴에 뮤트발생용 신호를 제공하는 스위치와, 뮤트신호에 따라 뮤트회로와 동시에 바이어스되며 카폰의 음성복조기 출력을 차량용 오디오의 파워앰프에 제공하는 스위칭부로 구성되고, 뮤트회로와 파워앰프 사이에는 수신음의 뮤트를 방지하기 위한 다이오드가 설치됨으로써, 차량용 오디오 및 카폰을 동시에 사용하고 스위치가 온될 때 오디오신호만 뮤트되고 카폰수신음은 증폭되어 스피커를 통하여 크게 청취할 수 있도록 한 장치이다.The present invention relates to a car phone receiving sound listening device using a vehicle speaker, and a switch for providing a mute generation signal to a microcomputer for controlling mute of vehicle audio, and simultaneously with a mute circuit according to a mute signal, the car demodulator output of the car audio It consists of a switching unit provided to the power amplifier, and a diode is installed between the mute circuit and the power amplifier to prevent the muting of the received sound, so that the car audio and car phone are simultaneously used and only the audio signal is muted when the switch is turned on and the car phone reception sound is amplified. It is a device that allows you to listen loudly through speakers.
