Title: SOUND OUTPUT SYSTEM, SOUND OUTPUT DEVICE, AND CONTROL DEVICE
Abstract:
A control device (30): generates a sound signal (L') in which a left-channel sound signal (L) and a first signal for diffraction erasure to erase a first diffraction wave (W1) that is outputted from a second speaker (4) and that propagates to a right-hand seat are synthesized, and outputs the sound signal (L') to a first speaker (3); generates a sound signal (R') in which a right-channel sound signal (R) and a second signal for diffraction erasure to erase a second diffraction wave (W2) that is outputted from the first speaker (3) and that propagates to a left-hand seat are synthesized, and outputs the sound signal (R') to the second speaker (4); outputs the right-channel sound signal (R) to a third speaker (6); and outputs the left-channel sound signal (L) to a fourth speaker (7).
