Abstract: PROBLEM TO BE SOLVED: To always display color video having high picture quality by providing a high-pass filter circuit attenuating a low-pass band including the resonance frequency of a mask among speech signals inputted to a main speaker so as to prevent the resonance of the mask even in a large volume. SOLUTION: The speech signals of L/R-channel inputted to the display device are inputted to high-pass filter circuits 12L and 12R respectively through buffer circuits 11L and 11R. The mask is weak with respect to the oscillation of main speakers 7L and 7R. Lest the speakers 7L and 7R generate the oscillation of frequency components resonating the mask, the circuits 12L and 12R attenuate the low-pass band including the resonance frequency of the mask within the speech signals. High-pass speech signals outputted from these circuits 12L and 12R are inputted to the speakers 7L and 7R. Thereby, the speakers 7L and 7R output speech in the high-pass band of each channel higher than the resonance frequency of the mask.
