用于安装在车辆上以控制车辆噪声的声音发生器
摘要：
用于安装在车辆上以控制源自由内燃发动机驱动的车辆的车辆噪声的声音发生器(100)特别是包括外壳(110)、扬声器(120)和至少一个压力补偿阀(130)。扬声器(120)和外壳(110)共同闭合容积(115)。此外，所述压力补偿阀(130)将由扬声器(120)和外壳闭合的容积(115)与所述外壳(110)的外部联接。压力补偿阀(130)由此穿过扬声器(120)所处的平面延伸。此外，公开了一种使用上述声音发生器(100)的用于控制通过由内燃发动机驱动的车辆的排气系统传导的声波的系统(200)。
摘要（英）：

A sound generator (100) mounts on a vehicle to manipulate vehicle noise originating from a vehicle operated by an internal combustion engine. The sound generator (100) includes a casing (110), a loudspeaker (120), and at least one pressure compensation valve (130). The loudspeaker (120) and the casing (110) together thereby enclose a volume (115). Further, the pressure compensation valve (130) couples the volume (115) enclosed by the loudspeaker (120) and the casing to an outside of the casing (110). The pressure compensation valve (130) thereby extends through a plane in which the loudspeaker (120) is located. A system (200) for manipulating sound waves propagating through exhaust systems of vehicles driven by an internal combustion engine uses the above sound generator (100).
