Abstract: Aspects of the subject technology relate to a device comprising a moving-coil speaker including a diaphragm to play low-frequency signals from an audio-signal source, and a piezoelectric transducer coupled to the diaphragm to play high-frequency signals from the audio-signal source. A coupler couples the diaphragm to a housing of the device.

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: Implementations of the subject technology provide an acoustic module with a dampening component integrated within the acoustic module to reduce deflection of a wire for a voice coil. The dampening component can take the form of an adhesive or a semisolid. During operation of the audio module, the wire vibrates and deflects in an oscillating manner. However, the dampening component can reduce the magnitude of deflection, while allowing the audio module to function in a desired manner, i.e., generate acoustical energy. By reducing the magnitude of deflection, the dampening component reduces the likelihood of mechanical fatigue of the wire, thus reducing the likelihood of damage to the wire.
