ON-VEHICLE STEREO REPRODUCING DEVICE

摘要

PURPOSE:To obtain a proper sound field in response to a seated position. CONSTITUTION:A seated position is detected by an encoder 18. A head position arithmetic operation circuit 16 calculates a position of a head based on the seated position. A control signal arithmetic operation circuit 14 outputs a delay control signal and an amplitude control signal based on the position of the head. A sound field adjustment circuit 12 delays a music signal based on the delay control signal and adjusts the sound volume based on the amplitude control signal. Thus, a proper sound field is reproduced in response to the seated position.
