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.
