Abstract
A speaker device includes left and right speakers and a correction part. The correction part corrects frequency characteristics of a stereo audio signal supplied to the left and right speakers so that transfer characteristics of the left and right speakers become predetermined transfer characteristics.
Claims16
A speaker device comprising:
- left and right speakers;
- and
- a correction part which corrects frequency characteristics of a stereo audio signal to be supplied to the left and right speakers so that transfer characteristics of the left and right speakers become predetermined transfer characteristics, wherein the correction part corrects the stereo audio signal so that the transfer characteristics of the left and right speakers are flattened across all audio signal frequencies.
A control method of a speaker device, comprising:
- correcting, by a speaker device comprising left and right speakers, frequency characteristics of an inputted stereo audio signal so that transfer characteristics of the left and right speakers become predetermined transfer characteristics, wherein the transfer characteristics of the left and right speakers are flattened across all audio signal frequencies;
- and
- supplying, by the speaker device, a corrected stereo audio signal to the left and right speakers.
A speaker device, operable in a monaural mode in which a monaural audio signal is supplied to a plurality of speakers and a stereo mode in which a stereo audio signal is supplied to the plurality of speakers, the speaker device comprising:
- a correction part which corrects frequency characteristics of the stereo audio signal so that transfer characteristics of the plurality of speakers in the stereo mode are different from transfer characteristics of the plurality of speakers in the monaural mode, wherein the correction part corrects the stereo audio signal so that the transfer characteristics of the left and right speakers are flattened across all audio signal frequencies.
