Abstract

본 발명은 텔레비젼의 스피커를 이용항 외부 오디오 장치의 음성 출력회로에 관한 것으로서, 종래의 경우에 텔레비젼 시스템에 장착된 스피커(SP1-SP2)는 단지 튜너에서 선국된 방송채널에 해당하는 음성신호만을 출력하였던 바, 본 발명의 목적은 스피커 장치가 없는 오디오 장치에서 출력되는 음성신호를 텔레비젼 시스템에 장착된 스피커로 출력할 수 있도록 텔레비젼의 스피커를 이용한 외부 오디오 장치의 음성 출력회로를 제공하는데 그 목적을 두고 있다.The present invention relates to an audio output circuit of an external audio device using a speaker of a television. In the conventional case, the speakers SP1-SP2 mounted in a television system output only a voice signal corresponding to a broadcast channel tuned by a tuner. SUMMARY OF THE INVENTION An object of the present invention is to provide a voice output circuit of an external audio device using a speaker of a television so as to output a voice signal output from an audio device without a speaker device to a speaker mounted in a television system. have.

따라서, 본 발명은 입력된 데이터에 따라 주변장치를 전반적으로 제어하는 마이컴과, 외부 오디오 장치의 출력단자로부터 공급되는 음성신호를 음성신호 증폭부에 공급 및 차단하는 음성신호 스위칭부와, 외부 오디오 장치에서 출력되는 음성신호를 증폭하고 이 증폭된 음성신호를 스피커로 출력하는 음성신호 증폭부를 이용하여 본 발명은 텔레비젼 시스템에 장착된 스피커 장치에 스피커 장치가 없는 오디오 장치를 접속 연결하여 사용함으로써 텔레비젼에 장착된 스피커 장치의 효율성을 높이는 장점이 있고, 스피커 장치가 없는 오디오 장치를 효율적으로 사용할 수 잇는 장점이 있다.Accordingly, the present invention provides a microcomputer for controlling a peripheral device generally according to input data, a voice signal switching unit for supplying and blocking a voice signal supplied from an output terminal of an external audio device to a voice signal amplifier, and an external audio device. The present invention uses a voice signal amplifying unit for amplifying a voice signal output from the speaker and outputting the amplified voice signal to a speaker. There is an advantage of increasing the efficiency of the speaker device, and there is an advantage that can effectively use the audio device without the speaker device.
