Abstract
A loudspeaker includes a movable diaphragm, a resilient centering device for centering and guiding the movement of the diaphragm, and a magnet system for controlling the movement of the diaphragm, where the diaphragm is positioned between the magnet system and the resilient centering device.
Claims5
A loudspeaker comprising:
- a frame disposed around a central axis;
- a magnet system mounted to the frame;
- a resilient centering device;
- a diaphragm movable relative to the central axis, the diaphragm mounted to the frame and mechanically communicating with the resilient centering device, and the diaphragm axially interposed between the magnet system and the resilient centering device;
- and
- a voice coil assembly, where the diaphragm mechanically communicates with the resilient centering device through the voice coil assembly, where the voice coil assembly includes a coil former interconnecting the diaphragm and the resilient centering device.
