Abstract

주변환경에 적응하여 자동으로 용량을 조정하는 회로에 관한 것이다. 출력의 일부를 입력으로 피드백하여 음량을 보상하던 종래의 기술에서 보상범위를 넓힐 뿐만 아니라 장비자체에 국한하여 보상하지 않고, 장비가 설치된 주변의 환경 변화에 적응적으로 보상 가능하도록 외부의 감지수단을 부가하여 음성출력 레베를 자동적으로 조정한다.The present invention relates to a circuit that adjusts capacity automatically in accordance with the surrounding environment. In the prior art, which compensates the volume by feeding back a part of the output, the external sensing means is not only expanded to compensate for the volume, but also can be adaptively compensated for changes in the surrounding environment where the equipment is installed. In addition, the audio output level is automatically adjusted.
