    Abstract: A transducer assembly comprising: a magnet motor assembly comprising a first magnet plate and a second magnet plate arranged along an axis, a first support plate positioned between inward facing surfaces of the first magnet plate and the second magnet plate, a second support plate positioned along an outward facing surface of the first magnet plate to form a first magnetic gap between the first support plate and the second support plate, and a third support plate positioned along an outward facing surface of the second magnet plate to form a second magnetic gap between the first support plate and the third support plate; a voice coil coupled to the magnet motor assembly, wherein the voice coil is positioned around the first support plate and within the first magnetic gap and the second magnetic gap; and a piston coupled to the voice coil, wherein the piston is operable to vibrate in a direction parallel to the axis.

    Abstract: An audio speaker having a speaker housing surrounding a back volume that is divided into a rear cavity behind a speaker driver and an adsorption cavity separated from the rear cavity by a permeable partition, is disclosed. More particularly, the adsorption cavity may be defined between the speaker housing and the permeable partition, and may be directly filled with adsorptive particles to adsorb gas during sound generation. The permeable partition may allow the gas to flow between the rear cavity and the adsorption cavity, and may retain the adsorptive particles within the adsorption cavity. Other embodiments are also described and claimed.

    Abstract: A planar magnetic driver including a radiating surface having a trace-free central region is described. The driver has a magnet defining an acoustic opening on a central axis. A diaphragm of the planar magnetic driver is held by mounts having a mounting profile around the central axis, and the diaphragm includes a radiating surface facing the acoustic opening. An innermost conductive trace on the diaphragm extends around a central region of the radiating surface within a magnetic flux of the magnet such that no conductive traces are on the central region. A radial distance between the innermost conductive trace and the mounting profile is less than another radial distance between the innermost conductive trace and the central axis. Accordingly, an excursion range of the diaphragm along the central axis is greater than a gap distance between the conductive trace and the magnet. Other aspects are also described and claimed.

    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.
