A plurality of speakers (23) disposed in a front and a rear of a passenger and a controller (21) configured to control a sound field in a vehicle cabin by individually driving the plurality of speakers (23). The controller (21) is configured, when an operation input for changing an acceleration/deceleration behavior of the vehicle is made, to set a normative acceleration/deceleration GxT depending on the operation input, to detect an actual acceleration/deceleration GxR, and to displace the sound field in the vehicle cabin in the direction of a change in the actual acceleration/deceleration behavior of the vehicle depending on the deviation G of the actual acceleration/deceleration GxR relative to the normative acceleration/deceleration GxT. That is, a change of an acceleration/deceleration behavior depending on the operation input is rendered before the change of the actual acceleration/deceleration behavior of the vehicle.
