A speaker of a virtual engine sound system, which informs the existence of an electric vehicle with a warning sound, is mounted on an under-cover installed on the bottom of an engine room of an electric vehicle, and is installed so that the warning sound generated from the speaker can be directed to the ground to transmit the warning sound reflected from the ground directly to pedestrians or surrounding drivers, thereby minimizing the path of transmission, so a speaker with a sound pressure level of a warning sound can be used. In addition, the transmission of a warning sound to surrounding configuration constituting an electric vehicle can be minimized, thereby increasing a warning effect while reducing noise felt inside the electric vehicle. In particular, the speaker is installed so that the warning sound can move to the ground and be reflected to be inclined forward of an electric vehicle, thereby more widely spreading warning sound while improving the performance of noise. Therefore, pedestrians or surrounding drivers are enabled to easily hear the warning sound and respond safely.

    전기차의 존재를 경고음으로 알려주는 가상 엔진 사운드 시스템의 스피커를 전기차의 엔진룸 바닥에 설치되는 언더 커버에 장착하되, 이 스피커에서 발생한 경고음이 지면을 향하도록 설치함으로써, 지면에서 반사하는 경고음이 바로 보행자나 주변 운전자에게 전달하게 해서 전달 경로를 최소화할 수 있어 경고음의 음압 레벨이 낮은 스피커를 사용할 수 있고, 또한 경고음이 전기차를 구성하는 주변 구성에 전달되는 것을 최소화하여 전기차 실내에서 느끼는 소음을 줄이면서도 경고 효과를 높일 수 있다. 특히, 경고음이 전기차의 앞쪽을 향해 경사지도록 지면으로 진행하여 반사하도록 스피커를 설치함으로써, 소음 성능을 개선하면서도 경고음이 더 넓게 퍼지게 하여 보행자나 주변 운전자가 경고음을 쉽게 들어서 안전하게 대처할 수 있도록 한다.
