Abstract
본 발명은 AV시스템이 설치된 주위의 소음 레벨에 따라 스피커로 출력되는 사운드 볼륨을 자동으로 조절할 수 있도록 된 AV시스템의 사운드 볼륨 조절 장치에 관한 것으로서, AV시스템 주위의 소음 레벨을 전기적인 신호로 변환 입력하는 마이크 수단(14)과, 이 마이크 수단(14)으로부터 출력되는 잡음 신호와 AV시스템내의 스피커(SP)로 인가되는 사운드 신호를 비교하는 비교 수단(15), 시청자가 볼륨 조절 방식을 수동 또는 자동 모드로 선택하기 위한 볼륨 조절 방식 선택 수단(16) 및 이 볼륨 조절 방식 선택 수단(16)에 의해 볼륨 조절 방식이 자동 모드로 선택된 경우에는 상기 비교 수단(15)에 의한 비교 결과에 따라 볼륨 조절을 실행하는 볼륨 제어 수단(19)을 포함하여 구성된 것을 특징으로 한다.The present invention relates to a sound volume control device of an AV system that is capable of automatically adjusting the sound volume output to a speaker according to the ambient noise level in which the AV system is installed, and converts the noise level around the AV system into an electrical signal. The microphone means 14, the comparison means 15 for comparing the noise signal output from the microphone means 14 with the sound signal applied to the speaker SP in the AV system, and the viewer manually or automatically adjusting the volume adjustment method. If the volume control method is selected by the volume control method selection means 16 for selecting the mode and the volume control method selection means 16 is selected as the automatic mode, the volume control is adjusted according to the comparison result by the comparison means 15. It characterized in that it comprises a volume control means 19 for execution.
