Abstract
An electrodynamic loudspeaker comprising a chassis, a diaphragm, and an actuator. The diaphragm is disposed within the chassis and has a front part and a back part. The actuator comprises a first actuator part connected to the diaphragm and a second actuator part connected to the chassis to cooperate with the first actuator part via an air gap. In order to obtain a large amplitude of the diaphragm a sub-chassis extends between the chassis and the diaphragm, a first flexible connecting element connecting the diaphragm to the sub-chassis, and a second flexible connecting element connecting the sub-chassis to the chassis.

An electrodynamic loudspeaker comprising
- a chassis,
- a diaphragm having a front part and a back part and disposed within the chassis,
- a suspension means for movably suspending the diaphragm from the chassis,
- an electromagnetic actuator comprising a first actuator part connected to the back part of the diaphragm and a second actuator part connected to the chassis to cooperate with the first actuator part via an air gap,
- wherein said speaker further comprises a sub-chassis, which extends between the chassis and the diaphragm, the suspension means connecting the sub-chassis telescopically to the diaphragm and telescopically to the chassis.
