Abstract: Examples of tooling fixtures and methods for manufacturing computing devices are described. According to some examples, a computer component may be shaped using successive steps of forging after deep drawing. In some examples, certain components may be assembled to form sub-assemblies of computer components and the sub-assembly may then be machined to drive closer tolerances. According to other examples, a work holding tool is described which may include a first plurality of individually movable pins for supporting a first surface of a work piece, the tool also having a second plurality of individually movable pins for applying a restraining force over a second opposite surface of the work piece to retain the work piece in position while maintaining it in its natural state.

Abstract: Examples of speaker assemblies are described. A speaker assembly according to some embodiments may include a speaker enclosure with a first opening (e.g., a speaker opening) and a second opening (e.g. a bass reflex port), a speaker unit mounted to the enclosure at the first opening, and an acoustic damping mechanism mounted to the enclosure at the second opening. The acoustic damping mechanism may be a dual-layer mesh screen including a first mesh with a first acoustic resistance (AR) for providing acoustic damping, and a second mesh with a second AR lower than the first AR. The second mesh may be nearly acoustically transparent and may serve to increase the stiffness of the first mesh. The first mesh may be bonded to the second mesh, and the dual-layer mesh screen may be coupled to the bass reflex port for reducing noise associated with turbulence at the port.

Abstract: Computing devices and microphone assemblies including acoustic waveguides are described. According to some examples, a computing device may include an enclosure, a microphone which may be spaced apart and angled relative to the interior surface of the enclosure to which the microphone may be coupled. The computing device may further include an acoustic waveguide disposed between the microphone and the interior surface of the enclosure, the acoustic waveguide having a passage for allowing acoustic energy to be transmitted from a microphone opening in the enclosure to the receiving element of the microphone (also referred to as sensing element, or microphone sensor).
