A loudspeaker including a chassis, a drive unit and a diaphragm. The drive unit has a stationary part secured to the chassis and a translatable part secured to the diaphragm. An outer edge of the diaphragm is suspended from the chassis by an edge suspension. The edge suspension has a plurality of straight portions, each straight portion having a respective first surface and a respective second surface which meet along an edge to provide a spring which permits the diaphragm to be moved relative to the chassis by the drive unit. The edge suspension has at least one corner portion, wherein the/each corner portion joins two of the straight portions together and includes at least one geometrical interruption formed therein. The/each geometrical interruption formed in the/each corner portion includes a first corrugation which varies in height along a first path which extends circumferentially around the edge suspension, and a second corrugation formed within the first corrugation which varies in height along a second path which extends across the first path. The/each corner portion may provide a continuous seal between the diaphragm and the chassis. |
