Abstract

본 발명은 텔레비젼 수상기의 음량 자동 조절장치에 관한 것으로서, 특히 텔레비젼 수상기가 설치된 주변환경의 밝기에 따라 음량을 자동 조절하여 주변의 밝고 어두움에 따라 적당한 음량이 사용자에게 제공되도록한 주변 밝기에 따라 음량을 조절하는 텔레비젼 수상기의 음량 자동 조절장치에 관한 것이다.The present invention relates to a device for automatically adjusting the volume of a television receiver, and in particular, automatically adjusts the volume according to the brightness of the surrounding environment in which the television receiver is installed so that the user can adjust the volume according to the ambient brightness so that the user can provide a suitable volume according to the surrounding light and darkness. It relates to a volume automatic control device of a television receiver to be adjusted.

일반적으로 같은 크기의 소리라도 밝을때보다 어두울때가 더 크게 들리게 되는데, 상용자가 설정한 만큼 만 음량이 제어되는 종래의 음량 조절장치는 주변 밝기에 따라 음량이 조절되지 않기 때문에 주변 밝기에 따라 사용자가 일일이 음량을 조정하여야만 하는 문제점이 있었다.In general, even when the sound of the same size is darker than when the sound is louder, the conventional volume control that is controlled only by the volume set by the commercial user, the volume is not adjusted according to the ambient brightness, so the user has to There was a problem that the volume should be adjusted.

따라서, 상기 문제점을 해결하기 위한 본 발명은 텔레비젼 수상기가 설치된 주변 환경의 밝기에 따라 음량을 자동 조절하여 주변의 밝고 어두움에 따라 적당한 음량이 사용자에게 제공되도록 한 주변 밝기에 따라 음량을 조절하는 텔레비젼 수상기의 음량 자동 조절장치이다.Accordingly, the present invention for solving the above problems is a television receiver for automatically adjusting the volume according to the brightness of the surrounding environment in which the television receiver is installed to adjust the volume according to the ambient brightness so that the appropriate volume is provided to the user according to the bright and dark surroundings. It is a volume automatic control device.
