Speaker spider having varying corrugation geometry
First Claim
1. A voice coil suspension element comprising:
- an aperture defining a central opening;
a membrane comprising a stretchable material, wherein the membrane is more stretchable along a first set of angular positions relative to the central opening than along a second set of angular positions relative to the central opening, and wherein the first set of angular positions and the second set of angular positions are separated by a 45 degree angle; and
a plurality of corrugations in the membrane, wherein each corrugation has;
a corresponding depth that varies azimuthally based on an angular position relative to the central opening,a minimum depth aligned with the first set of angular positions, anda maximum depth aligned with the second set of angular positions.

Abstract
Embodiments for a speaker spider of a loudspeaker are provided. The speaker spider may include a central opening and a plurality of concentric corrugations. Dimensions of the speaker spider may substantially homogenize stress on the speaker spiders during operation of the loud speaker. Dimensions of such a speaker spider that substantially homogenizes stress on the speaker spider during operation may involve one or more of (i) corrugations having azimuthally varying depths, (ii) corrugations having azimuthally varying crest and/or trough curvature radii, and (iii) corrugations having angularly varying distances from the central opening of the speaker spider, among other possibilities.
