Vehicle-mounted stereophonic sound field reproducer/silencer |
摘要 |
A vehicle-mounted three dimensional sound signal reproducing-silencing unit includes at least two speakers disposed for each of seats to be occupied by listeners so as to generate a three dimensional sound field space in a region inclusive of left and right external ears of each of the listeners, and three dimensional signal processing means for converting an output signal from a sound source into a three dimensional sound field signal for supplying it to each of the speakers, thereby reproducing a three dimensional sound field with rich presence for each of the seats. The unit also includes antiphase signal generating means for supplying a silencing signal to the three dimensional signal processing means, thereby silencing sounds for each of the seats without giving an effect on the other seats.
