    Abstract: 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.

    Abstract: Implementations of the subject technology provide vented audio transducers such as vented speakers. A speaker assembly may define a first volume under a dome of the speaker and a second volume under a surround of the speaker. The first volume and the second volume may be separated by a speaker structure such as a voice coil. By venting the first volume to the second volume, the disclosed vented speakers can provide a flatter response at high frequencies and lower distortion relative to conventional speakers, by equalizing the pressure under the diaphragm during operation.

    Abstract: A transducer assembly including a frame, a diaphragm positioned within the frame, a surround connecting the diaphragm to the frame, the surround having a corner section and a plurality of corrugations formed within the corner section, wherein each corrugation of the plurality of corrugations comprises a length dimension perpendicular to a line of maximum stress intersecting a radial axis of the corner section, a voice coil extending from one side of the diaphragm and a magnet assembly having a magnetic gap aligned with the voice coil.

    Abstract: An acoustic enclosure has a housing at least partially defining an acoustic chamber for an acoustic radiator. The housing defines an acoustic port from the acoustic chamber to a surrounding environment. An acoustic resonator has a first resonant chamber and a second resonant chamber. The acoustic resonator also has a first duct to acoustically couple the first resonant chamber with the acoustic chamber and a second duct to acoustically couple the second resonant chamber with the first resonant chamber. An electronic device can have an electro-acoustic transducer. Circuitry in the electronic device can drive the electro-acoustic transducer to emit sound over a selected frequency bandwidth. Damping provided by the first and the second resonant chambers can de-emphasize one or more frequencies and/or extend a frequency response of the acoustic enclosure to improve perceived sound quality emitted by the electronic device.

    Abstract: A micro-speaker assembly including an enclosure having an enclosure wall separating a surrounding environment from an encased space, wherein the enclosure wall defines an acoustic port from the encased space to the surrounding environment; a sound radiating surface positioned within the encased space and dividing the encased space into a front volume chamber and a back volume chamber, wherein the front volume chamber is acoustically coupled to a first surface of the sound radiating surface and the acoustic port, and the back volume chamber acoustically coupled to a second surface of the sound radiating surface; and a resonator acoustically coupled to the front volume chamber, wherein the resonator comprises a neck acoustically coupled to an acoustic cavity, and an opening to the neck is positioned at a distance from the acoustic port that corresponds to a quarter wavelength resonance of the front volume chamber.
