    Abstract: An electronic speaker comprising: a device housing defining an interior cavity and including a sidewall extending around the interior cavity between an upper portion and a lower portion of the device housing; first and second sound channels formed at opposing locations along the sidewall, each of the first and second sound channels comprising a plurality of openings formed through the sidewall; a passive radiator array comprising first and second passive radiators disposed within the interior cavity, spaced apart from each other in an opposing relationship and aligned to project sound through the first and second sound channels; an active driver disposed in the device housing and configured to generate sound in response to an electrical signal, the active driver comprising driver housing disposed at least partially between the first and second passive radiators, a magnet disposed within the driver housing, a voice coil and a diaphragm facing downwards towards the lower surface of the device housing; and an annular sound channel disposed along the bottom portion of the device housing adjacent to the diaphragm of the active driver.

    Abstract: A speaker driver including a frame and a magnet assembly positioned within the frame. A sound radiating surface may be suspended over the magnet assembly. The sound radiating surface may include a top face and a bottom face, and the bottom face may face the magnet assembly. A suspension member may suspend the sound radiating surface over the magnet assembly. The suspension member may include a top side connected to the bottom face of the sound radiating surface and a bottom side connected to the magnet assembly. A voice coil extends from the bottom face of the sound radiating surface.

    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: An enclosure for an electronic device is enclosed. The enclosure includes rib structures configured to improve structural support to prevent damage and to dissipate vibration throughout the enclosure. The rib structure can receive a speaker module and a cap member. The rib structure and the speaker module can combine to form a three-dimensional volume allowing the speaker module in which the speaker module may project sound, thereby enhancing acoustic performance. Also, the cap member may be adhesively attached to the rib structure to provide additional structural support against vibration and abuse caused by load forces associated with a drop event.

    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.
