Abstract
A speaker device includes a plurality of speaker units arranged in a line when seen from the front side of the speaker device. At least one of intervals between effective vibration regions of adjacent speaker units is set to a predetermined length. The predetermined length is a length that is set such that a difference between a distance from an end of one of the effective vibration regions, which form the at least one of intervals therebetween, to a listening position, and a distance from an end of the other of the effective vibration regions to the listening position can be less than half the shortest wavelength of a reproduced sound of each of the speaker units.
