<P>PROBLEM TO BE SOLVED: To enable automatic proper audio reproduction even when a viewer's position is different from a reference position. <P>SOLUTION: An acoustic device comprises: an audio signal reproduction section with a plurality of channels; an input section for inputting a detection signal indicating a position of the reproduction section and a viewer's position; and a control section that changes an audio signal, reproduced by the reproduction section depending on the position, by the detection signal. The control section determines a target value of the level and/or delay amount of the audio signal depending on the position, and changes the level and/or delay amount of the audio signal by setting a difference between the target value and a current value as an adjustment amount. <P>COPYRIGHT: (C)2013,JPO&INPIT |
