Abstract

[Problem] To achieve natural surround audio at a given viewing/listening position even when a sound bar cannot be placed under the center of a display device. [Solution] When a sound bar 1 is placed under the left side of a television receiver 3: the output timing of an Rch speaker 10-3 is delayed by T relative to that of a Cch speaker 10-1; the output timing of the speaker 10-1 is delayed by T relative to that of an Lch speaker 10-2: the output sound volume of the speaker 10-3 is made smaller by V than that of the speaker 10-1; and the output sound volume of the speaker 10-1 is made smaller by V than that of the speaker 10-2. When the sound bar 1 is placed under the right side of the television receiver 3: the output timing of the speaker 10-2 is delayed by T relative to that of the speaker 10-1: the output timing of the speaker 10-1 is delayed by T relative to that of the speaker 10-3: the output sound volume of the speaker 10-2 is made smaller by V than that of the speaker 10-1; and the output sound volume of the speaker 10-1 is made smaller by V than that of the speaker 10-3.
