Abstract

본 발명은 시스템 내장형 컴팩트 디스크 롬 드라이브 회로에서 외부 오디오신호와 내부의 오디오 신호를 합성하여 출력한다. 이를 수행하기 위하여 컴팩트 디스크 롬 드라이브 회로는 후면에 배치되며 외부 오디오기기의 출력단과 연결될 수 있는 입력단자와, 전면에 위치되며 스피커등과 연결될 수 있는 출력단자와, 컴팩트 디스크에 기록된 데이타를 재생하는 수단과, 입력단자로 부터 수신되는 오디오신호와 재생수단으로 부터 출력되는 오디오신호를 혼합하는 수단과, 혼합수단을 출력하는 오디오 신호의 음량을 조정하여 출력단자로 인가하는 수단으로 구성된다. 따라서 본 발명의 컴팩트 디스크 롬 드라이브 호로는 외부의 오디오 신호와 내부의 오디오 신호를 자체 내에서 합성할 수 있는 동시에 음량을 조정할 수 있다.The present invention synthesizes and outputs an external audio signal and an internal audio signal in a system built-in compact disc ROM drive circuit. To do this, the compact disc ROM drive circuit is arranged on the rear side and can be connected to an output terminal of an external audio device, an output terminal located on the front side and a speaker, and a data recorded on a compact disc. Means, a means for mixing the audio signal received from the input terminal and the audio signal output from the reproduction means, and a means for adjusting the volume of the audio signal outputting the mixing means and applying it to the output terminal. Therefore, the compact disc ROM drive horo of the present invention can synthesize the external audio signal and the internal audio signal in itself and adjust the volume at the same time.
