Abstract: Aspects of the subject technology relate to electronic devices having speakers such as microelectromechanical systems (MEMS) speakers. A MEMS speaker can include an electrostatically driven, corrugated MEMS structure to move air without a magnet, coil, or traditional speaker membrane, and thus provide a low-power, compact speaker with a large acoustically active area in a small volume. Neighboring folds in the corrugated MEMS structure may form pairs of MEMS electrodes that can be pushed together and/or pulled apart to deform the MEMS structure in a breathing motion that generates pressure differentials on opposing sides of the corrugated MEMS structure to generate sound. Additional modes of operation are described.

Abstract: A loudspeaker having a compressible lead wire is described. The lead wire carries an electrical audio input signal to a voice coil. The electrical audio input signal drives the voice coil to oscillate in an axial direction. The compressible lead wire includes an elastic portion that stretches and compresses in the axial direction to allow the voice coil to oscillate freely. The elastic portion includes several compressible elements that are located within a cavity of the loudspeaker. The compressible elements extend through the cavity in the axial direction. Other aspects are also described and claimed.
