Abstract

본 발명은 스피커가 장착된 모니터에 있어서 사용자가 모니터의 키입력수단을 이용하여 스피커의 오디오출력 상태를 능동적으로 제어할 수 있도록 하는 모니터의 오디오제어장치를 제공하고자 하는 것이다.An object of the present invention is to provide an audio control apparatus for a monitor that enables a user to actively control an audio output state of a speaker by using a key input means of the monitor.

이를 위해 본 발명은, 키입력부(28)를 통한 메뉴제어입력에 따라 OSD출력부(20)를 제어하여 메뉴제어화면을 CRT(16)로 출력함과 더불어 그 메뉴제어입력에 따른 비디오제어동작을 수행하는 마이컴(18)을 구비한 모니터에 있어서, 상기 마이컴(18)이 상기 키입력부(28)를 통한 메뉴제어입력에 따라 오디오제어동작을 수행하는 기능을 더 구비하고, 상기 마이컴(18)의 제어동작에 의해 오디오입력단자(30)로부터 오디오신호처리부(32)를 매개로 스피커로 전달되는 오디오신호를 차단하는 뮤팅회로(100)를 추가로 구비하여 이루어진다.To this end, the present invention, by controlling the OSD output unit 20 in accordance with the menu control input via the key input unit 28 outputs the menu control screen to the CRT (16) and the video control operation according to the menu control input In the monitor provided with a microcomputer 18, the microcomputer 18 further includes a function of performing an audio control operation according to a menu control input through the key input unit 28, It further comprises a muting circuit 100 for blocking the audio signal transmitted from the audio input terminal 30 to the speaker via the audio signal processing unit 32 by the control operation.
