Abstract: A digital image of a speaker spider may be received from an optical microscope or laser microscope. The digital image is filtered to fill in voids in the digital image, where the voids are indicative of holes in the speaker spider. The filtered digital image is compared to design criteria. An indication on a display screen may indicate whether the fabricated speaker spider meets the design criteria.

The loudspeaker may include a frame, a voice coil, a magnetic structure that includes a magnetic gap, a surround, a spider, and a circumferential spacer element. The circumferential spacer element may include a first tier attached to an outer rim of the surround; and a second tier attached to an outer rim of the spider, wherein the circumferential spacer element is coupled to the frame such that the voice coil is suspended at least partially within the magnetic gap.

Abstract: Example transducer assemblies are described here. An example transducer assembly may include a frame, a magnet carried by the frame, a voice coil operably coupled to the magnet, and a diaphragm. The diaphragm has an outer portion surrounding a central portion. The outer portion of the diaphragm has a generally concave shape, and the central portion of the diaphragm has a generally convex shape. The central portion of the diaphragm comprises a first surface facing toward the voice coil, and a second surface facing away from the voice coil. A coupler connects the voice coil to the first surface of the central portion.

Abstract: Object serialization is used to communicate references regarding shim objects. Shim objects are instantiated on one or more ranks of a distributed software application. The shim objects store a registration object in a distributed object cache for each rank. The registration object includes a unique identifier for a distributed array object and a reference to a local portion of the distributed array. The shim objects are serialized for communication of the stored references from a master rank of the distributed application to one or more worker ranks of the distributed application. Upon serializing the shim objects, the shim object's stored references are communicated from the distributed object cache for that rank to the one or more worker ranks of the distributed application. The shim objects are subsequently removed so that references to the underlying distributed array object are also removed, and memory previously allocated to the unique identifier is recoverable.
