According to the present invention, a virtual sound generation system for a vehicle comprises: a speaker mounted to an intake system and configured to generate reverse phase noise or virtual sound having an opposite phase to engine noise of an internal combustion engine; a valve movable between an open position for opening an outlet of an air cleaner and a close position for closing the outlet of the air cleaner; and an engine/electric control unit (ECU) controlling the speaker. The ECU controls the speaker so that the speaker generates the reverse phase noise in an operating condition in which the internal combustion engine operates, and can control the speaker to generate the virtual sound in an operating condition in which the internal combustion engine does not operate.

    본 발명에 따른 차량용 가상 사운드 발생시스템은, 흡기계에 장착되고, 내연기관의 엔진 소음과 반대위상을 가진 역상소음 또는 가상음을 발생하도록 구성된 스피커; 에어클리너의 출구를 개방하는 개방위치 및 에어클리너의 출구를 폐쇄하는 폐쇄위치 사이로 이동가능한 밸브; 상기 스피커를 제어하는 ECU; 및 상기 밸브를 제어하는 밸브 컨트롤러;를 포함하고, 상기 ECU는 상기 내연기관이 작동하는 운전조건에서 상기 스피커가 상기 역상소음을 발생하도록 상기 스피커를 제어하고, 상기 내연기관이 작동하지 않는 운전조건에서 상기 스피커가 가상음을 발생하도록 상기 스피커를 제어할 수 있다.
