VEHICLE ACOUSTIC CONTROL DEVICE, AND VEHICLE ACOUSTIC CONTROL METHOD

摘要

A vehicle acoustic control device includes: a plurality of speakers disposed on a periphery of a passenger; and a controller that controls a sound field in a vehicle cabin by individually driving the plurality of speakers. The controller rotates and displaces the sound field in a direction opposite to a changing direction of a vehicle behavior. At this time, when a frequency at a time of change of the vehicle behavior is higher than a predetermined frequency, the controller changes the sound field in the vehicle cabin in the direction opposite to the changing direction of the vehicle behavior, and increases a variation of the sound field as a variation of the vehicle behavior is being larger.

主权项

1. A vehicle acoustic control device comprising:
a plurality of speakers disposed on a periphery of a passenger; a sound field control unit configured to control a sound field in a vehicle cabin by individually driving the plurality of speakers; and a vertical behavior detection unit configured detect a vertical variation of a vehicle behavior, wherein the sound field control unit changes the sound field in the vehicle cabin in a direction opposite to a changing direction of the vehicle behavior depending on the vertical variation of the vehicle behavior detected by the vertical behavior detection unit.
