    Abstract: An additively manufactured component has an additively manufactured substrate and an inclusion. The substrate has a first region and a second region defining a first contour and a second contour, respectively. One or both of the first contour and the second contour is non-planar. The inclusion is positioned between the first region and the second region. The inclusion has a first major surface conforming to the first contour. The inclusion also has a second major surface. The second major surface can conform to the second contour. The inclusion can be a cavity, and the substrate can enclose the cavity or the cavity can be in open communication with an environment surrounding the substrate. The inclusion can be a member or an assembly of plural members. Modules and electronic devices incorporating an additively manufactured component also are described.

    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 loudspeaker having a compressible lead wire is described. The lead wire carries an electrical audio input signal to a voice coil. The electrical audio input signal drives the voice coil to oscillate in an axial direction. The compressible lead wire includes an elastic portion that stretches and compresses in the axial direction to allow the voice coil to oscillate freely. The elastic portion includes several compressible elements that are located within a cavity of the loudspeaker. The compressible elements extend through the cavity in the axial direction. Other aspects are also described and claimed.

    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: Aspects of the subject technology relate to electronic devices having speakers with resonators, such as Helmholtz resonators, acoustically coupled to the front volume of the speaker. A speaker module for an electronic device may include multiple resonators, including a first resonator that is acoustically separate from, and at least partially disposed within a second resonator. An acoustic barrier between the first resonator and the second resonator may have a liquid resistance that is different from a liquid resistance that is provided between the first resonator and a back volume of the speaker module and/or between an external environment of the speaker. In one or more implementations, a third resonator may be provided, that is spatially separated from first and second nested and/or adjacent resonators.
