Patent ID: 8442259

Claim:
A loudspeaker, comprising: a diaphragm extending from an inner diaphragm region to an outer diaphragm region, the outer diaphragm region bending at a defined angle relative to the inner diaphragm region; a frame; a voice coil former located below and providing structural support to the diaphragm, a top edge of the voice coil former interfacing with the diaphragm between the inner diaphragm region and the outer diaphragm region, whereby the inner diaphragm region is located inside the voice coil former and the outer diaphragm region is located outside the voice coil former; and a suspension member extending from an inner suspension region to an outer suspension region, the outer suspension region attaching to the frame, the inner suspension region overlapping and attaching with the outer diaphragm region to form a vibration confinement portion oriented at the defined angle relative to the inner diaphragm region; wherein an orientation of the vibration confinement portion at the defined angle isolates the inner diaphragm region from spurious bending waves from the outer suspension region.
