Patent ID: 7382893

Claim:
An electrodynamic loudspeaker comprising: a chassis, a movable body flexibly connected to the chassis and having a three-dimensional diaphragm with a base part and a top part that is wider than the base part, and an electromagnetic actuator for moving the body with respect to the chassis along a translation axis, which actuator includes: a stationary actuator part secured to the chassis and located above the diaphragm, and a translatable actuator part extends inside a space defined by the diaphragm and is translatable along the translation axis with respect to the stationary actuator part and is connected to the movable body in the region of the base part of the diaphragm, the stationary and translatable actuator parts magnetically co-operating with each other across an air gap, wherein the movable body includes, in the proximity of the base part of the diaphragm, a bridging element that is secured to the movable part of the actuator and extends radially with respect to the translation axis, the diaphragm and the bridging element being interconnected at least at a radial distance to the translatable part of the actuator.
