    Abstract: A micro speaker assembly including a speaker enclosure having an enclosure wall separating a surrounding environment from an encased space, wherein the enclosure wall defines, in part, an acoustic channel that acoustically couples the encased space to the surrounding environment, and the enclosure wall comprises a chemically etched insert molded metal portion that is mechanically interlocked and hermetically sealed to a plastic portion. The micro speaker further including a speaker assembly positioned within the encased space, the speaker assembly having a sound radiating surface facing the metal portion of the enclosure wall, a voice coil extending from the sound radiating surface, a magnet assembly having a magnetic gap aligned with the voice coil, and an acoustic chamber formed, in part, by the metal portion of the enclosure wall and the sound radiating surface.

    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.

    Abstract: A portable electronic device is described and includes a device housing, an acoustic housing disposed within the device housing and defining an interior volume, a speaker diaphragm assembly disposed within the interior volume and in fluid communication with a first opening leading out of the housing, and a microphone disposed within the interior volume and in fluid communication with a second opening leading out of the acoustic housing. Placing both the speaker diaphragm assembly and microphone within the same acoustic housing allows both components to share common power and data transfer circuitry. Furthermore, the additional volume of the acoustic housing used to accommodate the microphone can improve the acoustic performance of the speaker diaphragm assembly by increasing the back volume associated with the speaker diaphragm assembly.
