Abstract (en)
[origin: EP0616483A1] In the case of an electroacoustic transducer (1) having a diaphragm (5) and having a separating wall (24) lying behind the diaphragm (5), wall openings (25, 26, 27, 28 and 29, 30, 31, 32) which pass through the wall and are for making connections between a space (34) lying between the diaphragm (5) and one side (33) of the separating wall (24) and a space (36) lying on the other side (35) of the separating wall (24) being provided in this separating wall, and having a magnet system (16) arranged partly inside the space (36) lying on the other side (35) of the separating wall (24) and having a cover part (44) for rear covering of the space (36) lying on the other side (35) of the separating wall (24), the cover part (44) has a through-hole (45) with which the cover part (44) is put on an outer circumferential surface (46) of the magnet system (16) with acoustically sealed tolerance (no acoustically transmitting clearance). <IMAGE>
