Abstract: A piezoelectric microelectromechanical systems diaphragm microphone can be mounted on a printed circuit board. The microphone can include a substrate with an opening between a bottom end of the substrate and a top end of the substrate. The microphone can have two or more piezoelectric film layers disposed over the top end of the substrate and defining a diaphragm structure. Each of the two or more piezoelectric film layers can have a predefined residual stress that substantially cancel each other out so that the diaphragm structure is substantially flat with substantially zero residual stress. The microphone can include one or more electrodes disposed over the diaphragm structure. The diaphragm structure is configured to deflect when the diaphragm is subjected to sound pressure via the opening in the substrate.

Abstract: Aspects of the subject technology relate to electronic devices having microphones. An electronic device may include a microphone and a resonator for the microphone. The resonator may be formed in a device structure that is spatially separated from the microphone. The resonator may be formed in an interior wall of a housing of the electronic device, or in a support structure within an enclosure of the electronic device. A resonator and/or one or more damping features, may reduce a resonance effect, on the microphone, of a resonant cavity within the enclosure of the electronic device and adjacent the microphone.
