Abstract

An array speaker apparatus includes an array speaker in which plural speaker units are arranged in a single body, a sound source localization adding unit which generates left and right audio signals by performing localization processing for adding sound characteristics to audio signals of a front-left channel and a front-right channel on the basis of head transfer functions, and a sound emitting direction control unit which distributes the left and right audio signals to one or plural speaker units of the array speaker, and controls timing with which the speaker units output the audio signals so that a left sound emitted from the array speaker forms the same sound wavefront formed by a sound emitted from one of virtual point sound sources and that a right sound emitted from the array speaker forms the same sound wavefront formed by a sound emitted from the other of the virtual point sound sources.
