Abstract: Disclosed is a system and method for controlling a virtual engine sound of a hybrid vehicle or an electric vehicle. More specifically, the system includes a sensor for detecting when the vehicle is inside an enclosure; a virtual engine sound generation portion for generating the virtual engine sound of the vehicle; and a control portion for receiving data detected by the sensor to control the virtual engine sound based upon whether or not the vehicle is inside the enclosure, and transmitting a control signal corresponding to the data to the virtual engine generation portion.

Abstract: Disclosed herein is an apparatus for generating an operating sound of a vehicle, which does not require a separate installation space and thus imposes no spatial limitations on the design of the vehicle. The apparatus includes a rotatable mechanism and a film The rotatable mechanism is driven by a motor, and is provided with a plurality of blades. The film is provided on at least one of the blades, a first end of the film being secured to an edge of the blade and a second end being a free end.
