Classification: CPC H  B | IPC B  H

Claim 0:
1. An audio transducer, comprising:
a front volume;
a back volume; and
a corrugated microelectromechanical systems (MEMS) structure disposed between the front volume and the back volume,
wherein the corrugated MEMS structure comprises a single contiguous structure that extends, in a first dimension, from a first edge to a second edge, that includes a plurality of alternating folds disposed between the first edge and the second edge, and that comprises a plurality of MEMS electrodes each forming a part of the single contiguous structure, the part extending in a second dimension perpendicular to the first dimension between a corresponding pair of the plurality of alternating folds,
wherein a first one of the plurality of MEMS electrodes has a first cross-sectional thickness, and
wherein each of the corresponding pairs of the plurality of alternating folds for the first one of the plurality of MEMS electrodes has a second cross-sectional thickness that is less than the first cross-sectional thickness.
