Abstract
A mid-frequency loudspeaker drive unit includes a substantially conical diaphragm having a forward periphery and a surround connected to and extending from the forward periphery of the diaphragm to form a substantially smooth transition from the diaphragm to the surround, the diaphragm and the surround presenting a substantially smoothly continuous outwardly facing surface. The drive unit can be part of a compound loudspeaker drive unit including a high-frequency drive unit coaxially disposed within the diaphragm and a chassis encompassing the mid-frequency drive unit with the surround being secured to the chassis to form the smooth transition from the diaphragm to the surround.

A mid-frequency loudspeaker drive unit, comprising:
- a substantially conical diaphragm having a forward periphery;
- and
- a surround connected to and extending from said forward periphery of said diaphragm to form a substantially smooth transition from said diaphragm to said surround, said diaphragm and said surround presenting a substantially smoothly continuous outwardly facing surface, said surround and said diaphragm, together substantially in the shape of a single continuous curve.
A compound loudspeaker drive unit, comprising:
- a mid-frequency drive unit having a substantially conical diaphragm with:
- a center axis;
- and
- a forward periphery;
- a high-frequency drive unit coaxially disposed within said diaphragm;
- a chassis encompassing said mid-frequency drive unit;
- and
- said mid-frequency drive unit having a surround:
- connected to and extending from said forward periphery of said diaphragm;
- and
- secured to said chassis to form a substantially smooth transition from said diaphragm to said surround, said diaphragm and said surround presenting a substantially smoothly continuous outwardly facing surface, said surround and said diaphragm, together substantially in the shape of a single continuous curve.
