The vibrating apparatus has a housing (1 ) with a wall (2) provided with at least one aperture (3). A peripheral flange (4) protrudes from the wall (2) at the aperture (3) and has a plane surface (5) for abutment of a covering. The peripheral flange (4) is formed as an integral part of the wall (2), for instance by sheet metal forming, such as drawing, pressing, pulling, rolling and/or punching. |
