Abstract
A sound generating device for a vehicle exhaust system has a housing, a sound generator located in the housing, a housing wall that comprises an opening for the sound generator, and a sound channel that extends in the housing. The sound generator is mounted to a shoulder section of the opening such that the opening is closed by the sound generator and a front side and a rear side of the sound generator are assigned to different sides of the opening. The sound channel acoustically connects the rear side of the sound generator with the front side of the sound generator. The opening and the sound generator comprise a central axis and the sound channel runs at least partially around the central axis.
