Abstract: A sound generator, in particular for parking assistance systems for vehicles, has a housing (2) comprising a base part (4) and a top part (6), wherein the base part (4) defines a receiving space (8, 10), which can be covered by the top part (6), for receiving a diaphragm (38). The base part (4) is formed as one part together with the top part (6) via a connecting section (28), wherein the base part (4) and the top part (6) can be moved relative to each other and can be joined by a joining device (26).
