Abstract

A sound generating device is provided on a vehicle to reduce or generate engine sound, and is used in particular for an exhaust system of a combustion engine of the vehicle. The sound generating device has a housing into which a loudspeaker is positioned to divide an inner space of the housing into two sub-spaces separated in a gas-tight manner. A seal rim provides the gas-tight sealing of the loudspeaker towards the housing. An abutment rim positions the loudspeaker in the inner space of the housing. The abutment rim and the seal rim are spaced apart from each other in a direction of a central axis of the loudspeaker. There is also described an exhaust system of a combustion engine of a vehicle with a sound generating device.
