An edge-driven diaphragm loudspeaker driver is configured such that the suspension system of the driver is connected to the voice coil rather than to the diaphragm. Thus, the diaphragm in the loudspeaker is free of suspension systems connected to or extending from the diaphragm. By attaching the surround suspension to the voice coil rather than to the diaphragm, the diaphragm is isolated from the influence of spurious high frequency vibrations in the suspension system, thereby increasing the performance of the loudspeaker at high frequencies. The loudspeaker driver configuration also provides for a longer excursion range for the voice coil/diaphragm assembly, which allows for the driver components to be more accurately aligned during manufacturing, thereby enabling the loudspeaker driver to operate as a full range unit by producing low output frequencies.
A loudspeaker comprising:
A loudspeaker driver comprising:
A loudspeaker comprising:
A loudspeaker comprising:
The loudspeaker of claim 34, where the voice coil has a voice coil former having an upper end and a lower end, the voice coil former being attached to the diaphragm at its upper end.
The loudspeaker of claim 34, where the diaphragm is a concave shaped diaphragm.
The loudspeaker of claim 34, where the diaphragm is a convex shaped diaphragm.
The loudspeaker of claim 34, further comprising a permanent magnet.
The loudspeaker of claim 34, where the suspension member is the only suspension member in the loudspeaker.
The loudspeaker of claim 34, where both the inner and outer edges of the suspension member are flanges.
The loudspeaker of claim 34, where the cross-section of the suspension member between the inner and outer edges is configured generally as an arc.
The loudspeaker of claim 34, where the loudspeaker has more than one suspension member.
The loudspeaker of claim 34, where the voice coil includes a wrapper generally enclosing the voice coil and where the suspension member and diaphragm are attached to the wrapper of the voice coil.
A loudspeaker comprising:
