The present invention relates to a virtual engine sound generating device for a vehicle. The virtual engine sound generating device for a vehicle includes: a first casing; a second casing connected to the first casing and forming an inner space to mutually cooperate with the first casing; a vibrator installed in the inner space; a coil installed in the inner space to maintain a gap from the vibrator, wherein an electric current vibrating the vibrator is applied to the coil; a first elastic body installed between the vibrator and the second casing and elastically supporting one end of the vibrator on the first casing in accordance with a vibration direction of the vibrator; and a second elastic body installed between the first casing and the vibrator and having the same elastic modulus range as that of the first elastic body, wherein the second elastic body elastically supports the other end of the vibrator in accordance with the vibration direction of the vibrator on the second casing. Thus, the virtual engine sound generating device for a vehicle can obtain advantageous effect of accurately outputting intended sound quality and vibration without distortion of the vibration direction.

    본 발명은 차량용 가상 엔진 사운드 발생장치에 관한 것으로, 차량용 가상 엔진 사운드 발생장치는, 제1케이싱과, 제1케이싱에 결합되며 제1케이싱과 상호 협조적으로 내부 공간을 형성하는 제2케이싱과, 내부 공간에 배치되는 진동자와, 진동자와 간극을 유지하도록 내부 공간에 배치되며 진동자를 진동시키는 전류가 인가되는 코일과, 진동자와 제2케이싱의 사이에 배치되며 진동자의 진동 방향을 따른 진동자의 일단을 제1케이싱에 탄성적으로 지지하는 제1탄성체와, 제1탄성체와 동일한 탄성 계수 범위를 가지며 진동자와 제1케이싱의 사이에 배치되고, 진동자의 진동 방향을 따른 진동자의 타단을 제2케이싱에 탄성적으로 지지하는 제2탄성체를 포함하는 것에 의하여, 진동 방향의 왜곡이 없이 의도한 음질과 진동을 정확하게 출력하는 유리한 효과를 얻을 수 있다.
