<P>PROBLEM TO BE SOLVED: To provide a technology capable of preventing localization of a sound image to the vicinity of the center of a vehicle. <P>SOLUTION: In an acoustic system 1, stereo speakers 71 and 72 are provided corresponding to each of a driver seat 81 and a front passenger seat 82. In an acoustic device 10, two stereo acoustic signals with mutually different phases by "90°" are generated using stereo acoustic signals from one acoustic signal source. Then, one is output to the stereo speaker 71 for the driver seat 81, and the other is output to the stereo speaker 72 for the front passenger seat 82. Thus, since sound of the stereo speaker 71 for the driver seat 81 and sound of the stereo speaker 72 for the front passenger seat 82 are recognized as separate sound by a user, the localization of the sound image to the vicinity of the center of the longitudinal direction of the vehicle is prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
