Document Type and Number:
WIPO Patent Application WO/2014/174841
Kind Code:
A1
Abstract:
This vehicle acoustic control device is provided with a plurality of speakers (23) positioned around passengers, and a controller (21) that controls a sound field in a passenger compartment by individually driving the plurality of speakers (23). The controller (21) rotates or displaces a sound field in the opposite direction to changes in the motion of a vehicle. In this case, if the frequency during a change in the motion of the vehicle is higher than a predefined frequency, the sound field in the passenger compartment is changed in the opposite direction to the change in the motion of the vehicle, and the greater the amount of change in the motion of the vehicle, the more the sound field is changed.
