The invention belongs to the field of new energy vehicles, and particularly relates to a fuel automobile sound simulator outside a compartment. The sound simulator comprises a waterproof box body, a fuel automobile sound memory, an audio decoder, an audio power amplifier and a playing loudspeaker, and the playing loudspeaker 4 is arranged outside the compartment and is connected with the output ofan audio effect 3. A fuel automobile sound digital signal is stored in the fuel automobile sound memory is decoded and converted into an audio signal by the audio decoder, the audio power amplifier amplifies an output audio power signal and transmits the audio power signal to the playing loudspeaker in the waterproof box body, and the sound of the fuel automobile is emitted and played to a spacenearby the new energy automobile, so the problems that the new energy vehicle is too quiet in the driving process, and pedestrians nearby cannot perceive that the vehicle approaches under the condition that the vehicle whistles when the pedestrians are not used are solved, the road use efficiency is improved, and traffic accidents are reduced.
本发明属于新能源汽车领域,具体地说是一种车厢外燃油汽车声音仿真器,包括防水箱体、燃油车声音存储器、音频解码器、音频功放、播放扬声器,播放扬声器4安装在车厢外,并与音频功效3的输出相连;在燃油汽车声音存储器内存储的燃油汽车声音数字信号,经音频解码器解码转换为音频信号,由音频功放放大输出音频功率信号传输给防水箱体内的播放扬声器,发出燃油汽车声音播放到新能源汽车行驶附近空间,解决了新能源汽车行驶中过于安静,遇行人时在不使用汽车鸣笛情况下,无法使附近行人感知到有汽车靠近这一问题,提高道路使用效率并减少交通事故的发生。
