An electrodynamic loudspeaker comprising a chassis (2), a three-dimensional diaphragm (8) and an electromagnetic actuator (6). The diaphragm is connected to the chassis by a first flexible connecting means (18) provided near a front part (8a) of the diaphragm and by a second flexible connecting means (20) provided near a back part (8b) of the diaphragm. The actuator includes a stationary actuator element (6a) fixed to the chassis and a translatable actuator element (6b) fixed to the diaphragm. When energized, both actuator elements magnetically co-operate with one another over an air gap (16). In order to realize a flat but powerful speaker, the device as such and the air gap are outside the area (26) enclosed by the diaphragm but within the space (24) between both connecting means. |
