An array speaker apparatus, comprising: an array speaker in which plural speaker units (25-1, 25-2,..., 25-N) are arranged in a single body; a sound source localization adding unit (15A-D, 43A-D) which is adapted to generate left and right audio signals by performing localization processing for adding, to audio signals of a front-left channel and a front-right channel, on the basis of head transfer functions, sound characteristics; a sound emitting direction control unit (17A-E) which is adapted to distribute each of the left and right audio signals generated by the sound source localization adding unit (15A-D, 43A-D) to one or plural speaker units of the array speaker, and to control 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 as would be formed by a sound emitted from one of two virtual point sound sources located behind the array speaker and that a right sound emitted from the array speaker forms the same sound wavefront as would be formed by a sound emitted from the other of the two virtual point sound sources; and a calculating unit which is adapted to calculate a distance from the array speaker to a listening position in front of the array speaker, wherein the sound emitting direction control unit (17A-E) is adapted to change the plural speaker units, from which the audio signals are output, to other plural speaker units at other positions according to the calculated distance so that a horizontal angle (θ) formed by a straight line connecting the listening position and speaker units that emit sounds and the straight line connecting the center of the array speaker apparatus and the listening position is kept constant. an array speaker in which plural speaker units (25-1, 25-2,..., 25-N) are arranged in a single body; a sound source localization adding unit (15A-D, 43A-D) which is adapted to generate left and right audio signals by performing localization processing for adding, to audio signals of a front-left channel and a front-right channel, on the basis of head transfer functions, sound characteristics; a sound emitting direction control unit (17A-E) which is adapted to distribute each of the left and right audio signals generated by the sound source localization adding unit (15A-D, 43A-D) to one or plural speaker units of the array speaker, and to control 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 as would be formed by a sound emitted from one of two virtual point sound sources located behind the array speaker and that a right sound emitted from the array speaker forms the same sound wavefront as would be formed by a sound emitted from the other of the two virtual point sound sources; and a calculating unit which is adapted to calculate a distance from the array speaker to a listening position in front of the array speaker, wherein the sound emitting direction control unit (17A-E) is adapted to change the plural speaker units, from which the audio signals are output, to other plural speaker units at other positions according to the calculated distance so that a horizontal angle (θ) formed by a straight line connecting the listening position and speaker units that emit sounds and the straight line connecting the center of the array speaker apparatus and the listening position is kept constant.
