Zusammenfassung:	A sound generating device for a vehicle exhaust system has a housing 22, a sound generator 24 (specially a loudspeaker) located in the housing 22, a housing wall 30 that comprises an opening 32 for the sound generator 24, and a sound channel 36 that extends in the housing 22. The sound generator 24 is mounted to a shoulder section 40 of the opening 32 such that the opening is closed by the sound generator 24 and a front side and a rear side of the sound generator 24 are assigned to different sides of the opening 32. The sound channel 36 acoustically connects the rear side of the sound generator 24 with the front side of the sound generator. The opening 32 and/or the sound generator 24 comprise a central axis M and the sound channel 36 runs at least partially around the central axis M. In addition, the invention also discloses the vehicle exhaust system. 一种用于车辆排气系统的声音发生装置，该声音发生装置具有壳体(22)、位于壳体(22)中的声音发生器(24)特别是扬声器、包括用于声音发生器(24)的开口(32)的壳体壁(30)、以及在壳体(22)中延伸的声音通道(36)。声音发生器(24)安装至开口(32)的肩部部分(40)以使得开口(32)由声音发生器(24)闭
