Abstract
본 발명의 TV 자동 음량 조절장치는 TV 주위의 소음상태를 측정하여 그 소음크기에 따라 TV의 음량을 자동으로 조절할 수 있도록 한 것으로, 이를 위하여, 입력되는 음성 신호를 소정 레벨로 증폭하고 증폭된 음성 신호를 음량 조절 신호에 상응하여 신호 출력 수단을 통해 증폭하여 스피커로 출력하는 TV의 자동 음량 조절장치에 있어서, TV의 소정부분에 장착되며, TV 주변에 발생되는 소음을 측정하기 위한 수단; 상기 증폭된 입력 음성 신호와 상기 소음 측정 수단으부터의 잡음 신호를 입력으로 하여 각 상태의 신호대 잡음비에 따른 복수개의 음량 조절용 기준값을 계산하여 이를 저장하고, TV주변의 입력 음성 신호와 상기 잡음 신호의 변화시에 상기 저장된 기준값에 의거하여 상기 신호 출력 수단으로부터 출력되는 음성 신호의 음량 레벨을 조절하는 수단을 더 구비하여 구성하여 최적의 상태에서 TV시청을 할 수 있도록 한다.TV automatic volume control device of the present invention is to measure the noise state around the TV to automatically adjust the volume of the TV according to the noise level, for this purpose, to amplify the input voice signal to a predetermined level and amplified voice An automatic volume control apparatus for a TV which amplifies a signal through a signal output means in correspondence with a volume control signal and outputs the same to a speaker, the apparatus comprising: a means mounted to a predetermined portion of the TV and measuring noise generated around the TV; The amplified input voice signal and the noise signal from the noise measuring unit are input to calculate and store a plurality of volume control reference values according to the signal-to-noise ratio of each state, and store the same. The apparatus may further include a means for adjusting a volume level of the audio signal output from the signal output means based on the stored reference value at the time of change so that the TV can be watched in an optimal state.
