Abstract
A speaker system includes a first speaker; a second speaker; and a first spacer for separating the first speaker and the second speaker from each other so that the first speaker and the second speaker face each other. The first speaker and the second speaker are located so that opposing faces of the first speaker and the second speaker output sounds of an identical phase. The first speaker, the second speaker and the first spacer form a first sound path through which the sounds output from the opposing faces of the first speaker and the second speaker pass. The speaker system according to the present invention includes n number speakers and (n−1) number of spacers and can be arranged so that the opposing faces of even-numbered speakers and odd-numbered speakers output sounds of an identical phase.
