A sound generator, for a system for influencing sound waves propagating through an exhaust system of a vehicle driven by an internal combustion engine, includes an enclosure comprised of an upper shell and a lower shell. A bell mouth, supported by the lower shell and penetrating the lower shell, is configured for a fluid communication with the exhaust system. A loudspeaker is disposed in the enclosure and supported by the bell mouth. The lower shell of the enclosure supports the upper shell of the enclosure. The bell mouth is solely supported by the lower shell of the enclosure. The lower shell may include at least one air-tight feed-through for a control wire connected to the loudspeaker and/or at least one pressure equalizing valve. An anti-sound system is provided that includes the sound generator and a vehicle is provided with the anti-sound system.
