1. A speaker apparatus comprising:
- a first speaker which reproduces an audio signal; and
a second speaker which reproduces the audio signal and which is disposed and separated from said first speaker by a predetermined distance in a horizontal direction,at least one of said first speaker and said second speaker having a phase changing device for changing a phase of the audio signal by a predetermined amount of phase on the basis of (i) a frequency of the audio signal and (ii) the predetermined distance,the phase changing device (i) reducing the predetermined amount as the frequency of the audio signal approaches a reference frequency corresponding to a wavelength almost twice as long as the predetermined distance and (ii) increasing the predetermined amount as the frequency of the audio signal departs from the reference frequency.

Abstract
A speaker device comprises a first speaker (SP1) for reproducing an audio signal and a second speaker (SP2) adapted for reproducing an audio signal and spaced from the first speaker horizontally by a predetermined distance. At least one of the first and second speakers phase has varying means (APF1, APF2, . . . ) for varying the phase of the audio signal by a predetermined quantity of phase according to (i) the frequency of the audio signal and (ii) the predetermined distance.
