Abstract

본 발명은 오디오신호를 처리하여 출력하는 장치에 관한 것으로서, 감지부는 전화선의 전압으로 전화기가 통화상태인지를 감지하여, 감지된 결과를 뮤트신호출력부에 인가한다. 뮤트신호출력부는 전화기가 통화상태일때에는 오디오처리부에 뮤트신호를 인가하여 오디오처리부로 하여금 처리된 오디오신호를 스피커에 인가하지 않게 하므로써, 사용자가 오디오장치의 오디오음에 방해받지 않고 전화통화를 원활하게 할 수 있게 하는 효과가 있다.The present invention relates to an apparatus for processing and outputting an audio signal, wherein the sensing unit detects whether a telephone is in a call state by a voltage of a telephone line, and applies the detected result to the mute signal output unit. The mute signal output unit applies a mute signal to the audio processing unit when the phone is in a call state so that the audio processing unit does not apply the processed audio signal to the speaker, so that the user can make a telephone call smoothly without being disturbed by the audio sound of the audio device. It has the effect of making it possible.
