Abstract:
A loudspeaker driver surround  2  comprises a flexible, generally annular element having a central axis  8  along which in use a diaphragm is driven, an outer edge  6  for fitment to an enclosure and an inner edge  4  for fitment to the diaphragm, with a roll surface which extends between the edges and which projects in the direction of the axis, wherein the roll surface has a shape formed by a plurality of axial corrugations  10  extending generally radially with respect to the annular element between the outer and inner edges thereof, the corrugations being shaped and configured such that the roll surface is non-axisymmetric about the axis, and the arrangement being such that cross-sections of the roll surface which extend radially with respect to the annular element between the outer and inner edges thereof have a substantially constant length at all circumferential positions around the annular element and so that the shape of the said cross-section varies continuously between circumferential positions around the annular element, the corrugations giving the projecting roll surface an order of rotational symmetry of at least 30.

Claim (Index 8):
The loudspeaker driver surround as claimed in  claim 3 , wherein if the parts of the corrugations which are most axially distant from the circumferential edges at different radii are used to generate a leading surface, that leading surface would not be planar.
