1. A speaker, comprising:
a front volume;
a back volume; and
a microelectromechanical systems (MEMS) structure disposed between the front volume and the back volume,
wherein the MEMS structure comprises a plurality of pairs of MEMS elements, and wherein each of the pairs of MEMS elements is configured to be pushed together and pulled apart in a breathing motion that generates sound for the speaker.
