Abstract

본 발명은 오디오출력부 주변의 잡음에 따라 출력되는 음성신호의 크기가 자동 조절되는 기능을 구비한 오디오증폭시스템에 관한 것으로, 종래의 오디오증폭시스템의 음성신호 출력은 고정적이므로 인하여 오디오출력부 주변의 잡음신호의 변화에 따라 잘 들리기도 하고 잘 들리지 않기도 하는 문제점이 있으므로, 본 발명은 오디오 출력부 주변에서 발생되는 잡음신호를 검출하여 검출된 잡음신호의 레벨보다 상대적으로 큰 레벨을 갖도록 신호절대가변기의 출력되는 오디오신호가 연동적으로 조절되도록 하므로, 항상 정확히 음성신호를 들을 수 있으며, 잡음신호의 변화에 따라 일일이 수동으로 음성신호의 크기를 조절하은 번거로움이 없어진다.The present invention relates to an audio amplification system having a function of automatically adjusting the size of a voice signal output according to noise around an audio output unit, and a voice signal output of a conventional audio amplification system is fixed, There is a problem in that it is difficult to hear the change of the noise signal. Therefore, the present invention detects a noise signal generated in the vicinity of the audio output unit, and detects the absolute value of the absolute value of the signal, So that it is possible to always hear the voice signal accurately and it is not necessary to manually adjust the size of the voice signal according to the change of the noise signal.
