Abstract

좌,우측 채널신호(AL,AR)를 증촉하는 2개의 증폭기와, 헤드폰잭의 삽입 유무에 따라 상기의 증폭된 신호를 좌,우측 내부스피커 및 외부스피커로 출력하기 위한 스위치를 구비한 음향출력자동 제어장치가 기술되는 바, 이는 외부스피커잭의 삽입 유무를 검출하여 버스콘트롤 신호를 발생하기 위한 마이크로 프로세서와; 상기의 콘트롤신호를 입력받아 좌,우측 채널신호의 레벨을 제어하되, 스피커잭의 삽입시에는 좌,우측 채널신호의 레벨을 약 30%정도 감소시키고, 스피커잭이 삽입되지 않았을 경우에는 정상적인 좌,우측 채널신호를 출력시키기위한 음향처리기로 구성시켜서 된 것이다. 또한, 음향처리기는 스피커잭의 삽입시에는 좌,우측 채널신호의 레벨을 약 2배정도 증가시키고, 스피커잭이 삽입되지 않았을 경우에는 정상적인 좌,우측 채널신호를 출력할 수 있다.Sound output automatic with two amplifiers for boosting the left and right channel signals AL and AR, and a switch for outputting the amplified signal to the left and right internal speakers and the external speakers depending on whether the headphone jack is inserted or not. The control device is described, which includes a microprocessor for detecting the presence or absence of an external speaker jack and generating a bus control signal; Receive the above control signal and control the level of left and right channel signal. When inserting speaker jack, reduce the level of left and right channel signal by about 30%. It consists of sound processor for outputting right channel signal. In addition, the sound processor may increase the level of the left and right channel signals by about two times when the speaker jack is inserted, and may output normal left and right channel signals when the speaker jack is not inserted.
