<p>A speaker unit (1) comprising a baffle plate (3), at least a pair of speakers (5, 6) fixed to the baffle plate in reverse directions, and a reflection structure (7) for reflecting a sound reproduced by the pair of speakers in a desired direction. One group of speakers (5a, 6a) and the other group of speakers (5b, 6b) constituting the pair of speakers are equivalent speakers of the same type and arranged such that one group of speakers and the other group of speakers can be driven with reverse phases. Distortion can be reduced by offsetting when respective groups of speakers are fixed to the baffle plate in reverse directions, and driven with reverse phases.</p> |
