Abstract
본 발명은 텔레비전 수상기가 설치되어 있는 주변의 소음레벨에 따라 스피커로 출력되는 음성신호의 주파수대역을 다르게 조정하도록 된 주변 소음레벨에 따른 음성주파수대역 처리기능을 갖춘 텔레비전 수상기에 관한 것으로서, 텔레비전 수상기가 설치되어 잇는 주변의 음성신호를 전기적으로 신호로 변환하여 입력하는 마이크로폰과, 상기 마이크로폰을 통해 입력된 음성신호를 적분하는 적분수단, 상기 적분수단에 의해 적분된 신호의 레벨을 소정의 기준전압과 비교하여 그에 따른 비교결과 신호를 출력하는 비교수단및, 상기 비교수단에 의한 비교결과를 근거로 음성신호의 주파수대역에 따른 증폭도를 제어하는 제어수단을 포함하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver having an audio frequency band processing function according to an ambient noise level, wherein the frequency band of an audio signal output to a speaker is differently adjusted according to an ambient noise level in which a television receiver is installed. A microphone for electrically converting the installed voice signal into an electrical signal, an integration means for integrating the voice signal input through the microphone, and a level of the signal integrated by the integration means with a predetermined reference voltage And a control means for controlling the amplification degree according to the frequency band of the voice signal based on the comparison means for outputting the comparison result signal according to the comparison result.
