According to an embodiment of the present invention, a device for outputting a sound of a vehicle comprises: a sensor detecting driving speed of a vehicle and the number of rotations of a driving motor; a storage unit storing an anti-phase sound source of a noise according to the number of rotations of the driving motor; and a control unit controlling the anti-phase sound source corresponding to the number of rotations of the driving motor detected among the anti-phase sound sources stored in the storage unit to be outputted when the driving speed of the vehicle exceeds preset speed. Without additional cost or weight, the present invention reduces the noise generated by electronic components inside the vehicle to provide a comfortable indoor environment of the vehicle to a passenger.

    본 발명의 실시예에 따른 차량의 사운드 출력 장치는 차량의 주행 속도 및 구동 모터의 회전수를 감지하는 센서와, 상기 구동 모터의 회전수에 따른 소음의 역위상 음원이 저장된 저장부 및 상기 차량의 주행 속도가 기 설정된 속도를 초과하는 경우, 상기 저장부에 저장된 역위상 음원 중에서 감지된 구동 모터의 회전수에 상응하는 상기 역위상 음원을 출력하도록 제어하는 제어부를 포함하여, 추가되는 비용이나 중량없이 차량 내 전장 부품들에 의해 발생되는 소음을 저감시켜, 탑승자에게 편안한 차량 실내 환경을 제공할 수 있다.
