Television receiver with voice frequency band processing according to ambient noise level

摘要

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.
