Abstract
본 발명은 모니터의 외부 스피커 제어 회로에 관한 것으로, 이 제어 회로는 외부기기에서 출력되는 오디오 신호를 인가받기 위한 오디오 입력부(12)와, 이 오디오 입력부(12)를 통해 입력된 오디오 신호를 증폭하기 위한 증폭부(22), 뮤트(MUTE)신호를 출력하기 위한 마이컴(32), 상기 증폭부(22)에서 증폭된 신호가 음향으로 출력되는 내부 스피커(42), 상기 오디오 입력부(12)를 통해 입력된 오디오 신호가 음향으로 출력되는 외부 스피커(52)가 구비된 모니터의 스피커 제어 회로에 있어서, 상기 마이컴(32)에서 출력되는 뮤트(MUTE)신호에 따라 상기 외부 스피커(52)의 작동여부를 제어하는 외부 스피커 제어부(60)를 포함하여 구성되어 있고, 상기와 같이 구성되어 있는 회로는 상기 스피커들(42,52)의 작동을 중단시키고자 사용자가 모니터 외면에 설치되어 있는 스위치를 간단하게 조작하므로써, 모니터 내부의 스피커와 상기 외부의 스피커가 동시에 작동이 중단되는 효과가 있다.The present invention relates to an external speaker control circuit for a monitor, which comprises an audio input part (12) for receiving an audio signal outputted from an external device, and a control part for amplifying an audio signal inputted through the audio input part A microphone 32 for outputting a mute signal, an internal speaker 42 for outputting a signal amplified by the amplifying unit 22, and an audio input unit 12 In the speaker control circuit of the monitor provided with the external speaker 52 in which the input audio signal is outputted as sound, it is determined whether or not the external speaker 52 is operated according to the MUTE signal outputted from the microcomputer 32 And an external speaker control unit 60 for controlling the speaker. In order to stop the operation of the speakers 42 and 52, By a simple operation, there is an effect that the external speaker and the speaker of the monitor at the same time stop the operation.
