Abstract

본 발명은 일반적인 CD나 LD 또는 비디오-CD와 같은 음향기기에서 라인 출력단자에서 출력되는 아날로그의 음성신호를 이용하여 가라오케 기능을 구현할 수 있도록 한 음향기기의 가라오케용 음성출력 처리회로에 관한 것인 바, 그 특징은 라인 출력단자를 통해 나오는 음성 신호를 디지탈 처리하여 전송하는 디지탈 신호 처리수단과, 상기 디지탈 신호 처리수단에서 출력되는 음성 신호를 복호화하는 음성 디코딩수단과, 상기 음성 디코딩수단의 디지탈 출력 데이터와 외부의 마이크 입력신호를 받아서 에코처리, 음성 소거처리, 음성 변환처리, 서라운드처리, 키제어처리에 관한 동작을 수행하는 음성신호 처리수단과, 상기 음성 디코딩 수단과 음성신호 처리수단의 동작을 제어하는 제어수단과, 동작모드 선택신호에 따라 정상적인 음성 또는 가라오케 모드를 선택적으로 출력하기 위한 출력 선택수단과, 상기 음성 출력신호를 다시 아날로그신호로 변환하는 D/A 변환수단으로 구성함에 있다.The present invention relates to a voice output processing circuit for karaoke of an audio device capable of implementing a karaoke function using an analog audio signal outputted from a line output terminal in an audio device such as a general CD, LD, or video-CD. A digital signal processing means for digitally processing and transmitting a voice signal output through a line output terminal, a voice decoding means for decoding a voice signal output from the digital signal processing means, and digital output data of the voice decoding means. Voice signal processing means for receiving an external microphone input signal and performing operations related to echo processing, voice cancellation processing, voice conversion processing, surround processing, and key control processing, and controlling operations of the voice decoding means and the voice signal processing means. Control means, and normal voice or karaoke according to the operation mode selection signal. And output selection means for selectively outputting the mode, and D / A conversion means for converting the audio output signal back into an analog signal.
