PURPOSE: A sound device for a television receiver and an audio equipment is provided to remove noise generated when converting from a stereo mode to a mono mode because a received signal becomes weak when receiving signals by using the television receiver and the audio equipment. CONSTITUTION: A sound device for a television receiver and an audio equipment includes a signal receiving portion(100), a sound mode converting portion(102), a stereo mode driving portion(104), a mono mode driving portion(106), a noise decreasing unit(108), a switching portion(110). The signal receiving portion receives a broadcasting signal. The sound mode converting portion converts a mode status of a sound signal into a mono mode or stereo mode. The stereo mode driving portion drives the sound signal as a stereo mode. The mono mode driving portion drives the sound signal as a mono mode. The noise decreasing unit decreases noise of the sound signal output from the mono mode driving portion. The switching portion switches the broadcasting signal received from the signal receiving portion into the stereo mode driving portion or mono mode driving portion according to the mode of the sound signal converted from the sound mode converting portion. |
