Abstract

본 발명은 스피커로 출력되는 음량의 최대치를 사용자가 특정 레벨로 제한할 수 있도록 함으로써 스피커를 통해 과대한 음량의 음성신호가 출력되는 것을 방지 할 수 있도록 된 출력음량제한기능을 갖춘 텔레비전 수상기에 관한 것으로, 각각 소정의 레벨제한 범위를 갖추어 스피커로 출력되는 음성신호의 레벨을 제한하는 다수의 레벨제한수단과, 음성신호를 상기 레벨제한수단에 선택적으로 결합하는 스위칭수단, 시청자가 음성출력레벨의 제한범위를 입력하기 위한 입력수단 및, 상기 입력수단에 의해 입력된 음성출력레벨 제한범위를 근거로 상기 스위칭 수단을 스위칭제어하는 제어수단을 포함하여 구성된 것을 특징으로 한다.The present invention relates to a television receiver having an output volume limit function, which enables the user to limit the maximum volume of the volume output to the speaker to a specific level so as to prevent excessive volume of audio signals from being output through the speaker. A plurality of level limiting means for limiting the level of the audio signal output to the speaker, each having a predetermined level limiting range; And input means for inputting the control means, and control means for switching and controlling the switching means on the basis of the voice output level restriction range input by the input means.
