    摘要: This disclosure provides systems, methods and apparatus for sense elements in an electromechanical microphone device. In one aspect, a piezoelectric sense element may include a glass substrate, electrode layers, piezoelectric layers, and elastic layers. The elastic layers may serve to modify the neutral plane of the piezoelectric sense element. Including an elastic layer or layers to modify the neutral plane of the piezoelectric sense element may serve to configure the sense element such that the piezoelectric layer generates a voltage in response to a sound wave or may serve to increase the sensitivity of the sense element.

    摘要: This disclosure provides systems, methods and apparatus for glass-encapsulated microphones. In one aspect, a glass-encapsulated microphone may include a glass substrate, an electromechanical microphone device, an integrated circuit device, and a cover glass. The cover glass may be bonded to the glass substrate with an adhesive, such as epoxy, or a metal bond ring. The cover glass may have any of a number of configurations. In some configurations, the cover glass may define an aperture for the electromechanical microphone device at an edge of the glass-encapsulated microphone. In some configurations, the cover glass may define a cavity to accommodate the integrated circuit device that is separate from a cavity that accommodates the electromechanical microphone device.

    摘要: This disclosure provides systems, methods and apparatus for microspeaker devices. In one aspect, a microspeaker element may include a deformable dielectric membrane that spans a speaker cavity. The deformable dielectric membrane can include a piezoactuator and a dielectric layer. Upon application of a driving signal to the piezoactuator, the dielectric layer can deflect, producing sound. In some implementations, an array of microspeaker elements can be encapsulated between a glass substrate and a cover glass. Sound generated by the microspeaker elements can be emitted through a speaker grill formed in the cover glass.

    摘要: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for making and using accelerometers. Some such accelerometers include a substrate, a first plurality of electrodes, a second plurality of electrodes, a first anchor attached to the substrate, a frame and a proof mass. The substrate may extend substantially in a first plane. The proof mass may be attached to the frame, may extend substantially in a second plane and may be substantially constrained for motion along first and second axes. The frame may be attached to the first anchor, may extend substantially in a second plane and may be substantially constrained for motion along the second axis. A lateral movement of the proof mass in response to an applied lateral acceleration along the first or second axes may result in a change in capacitance at the first or second plurality of electrodes.
