Abstract
A sound generator () for an exhaust system () of an internal combustion engine of a motor vehicle () includes a housing (), with an electroacoustic converter () having a membrane () separating a housing rear volume () from a housing front volume (). A connection pipe () connects the front volume () of the sound generator () to an exhaust gas-carrying exhaust gas line () fluidically and acoustically. To reduce the risk of damage to the membrane (), for example, in case the housing () becomes flooded, a pressure equalization line () is connected by a proximal end () to the housing () on the outside and is connected fluidically with the rear volume () through an opening () in the housing. A distal end () of the pressure equalization line () is at a spaced location from the housing ().
