Cylindrical mems structures for audio components

A speaker, comprising:

• a front volume;
• a back volume;
• a cylindrical corrugated microelectromechanical (MEMS) structure disposed between the front volume and the back volume;
• and
• an additional cylindrical corrugated MEMS structure disposed between the front volume and the back volume.

An electronic device, comprising:

• a speaker, comprising:
• a front volume;
• a back volume;
• and
• a cylindrical corrugated microelectromechanical systems (MEMS) structure having an open cylindrical core that defines at least a portion of the front volume, wherein the cylindrical corrugated MEMS structure comprises a free end that is opposite to a fixed end of the cylindrical corrugated MEMS structure, and wherein the free end is configured to move into the open cylindrical core to deform the cylindrical corrugated MEMS structure to generate sound with the speaker by moving air within the open cylindrical core.
