Title
(EN) Automobile

Abstract
(EN) The invention provides an automobile. The automobile comprises an automobile door with a containing space and a vehicle-mounted sound wave device arranged in the automobile door. The vehicle-mounted sound wave device comprises a shell with a cavity and a sound production unit which is accommodated in the cavity and is fixed with the shell. The sound production unit divides the cavity into a frontsound guide cavity and a rear coupling cavity, the shell is provided with a first sound outlet hole and a second sound outlet hole which are communicated with the front sound guide cavity and spaced from each other, the front sound guide cavity is communicated with the space in the automobile through the first sound outlet hole, and the front sound guide cavity is communicated with the space outside the automobile through the second sound outlet hole. Sounds emitted by the sound production unit and used for simulating sports car engine sounds can be transmitted to the in-car space and the out-car space through the sound guide front cavity, the first sound outlet hole and the second sound outlet hole. Sounds emitted by one sound production unit can be simultaneously transmitted to the spacein the vehicle and the space outside the vehicle, cost and design complexity increase caused by installing the sound production unit on the outer contour of the vehicle is avoided, and the difficultyof achieving driving experience of simulating sports vehicle engine sound is lowered.
(ZH) 本发明提供了一种汽车。该汽车包括具有收容空间的车门和设于车门内的车载声浪装置,车载声浪装置包括具有腔体的壳体以及收容于腔体内并与壳体固定的发声单元,发声单元将腔体分隔为导声前腔以及耦合后腔,壳体上设有与导声前腔连通且相互间隔的第一出声孔和第二出声孔,第一出声孔将导声前腔与车内空间连通,第二出声孔将导声前腔与车外空间连通。发声单元发出模拟跑车引擎声的声音能够经导声前腔、第一出声孔和第二出声孔传播到车内空间和车外空间,实现一个发声单元发出的声音能够同时传播到车内空间和车外空间,避免了在车外部轮廓上安装发声单元造成的成本和设计复杂度的增加,同时降低了实现模拟跑车引擎声的驾驶体验的难度。
