摘要： An electric motor including two magnetic assemblies each having an even number of magnets in a circular arrangement, the magnets arranged in a bucking configuration with like poles directed at each other. There are a plurality of ferrous members for each of the magnetic assemblies arranged between each of the magnets. The ferrous members having a face that is directed radially toward a face of another ferrous member of the corresponding magnetic assembly. An electromagnetic assembly has a plurality of electromagnetic members arranged in a generally circular arrangement and is located radially between the two magnetic assemblies. Each electromagnetic member has a ferrous element with an electrical conductor wound around the ferrous element, each ferrous element having an inward and outward face respectively being directed to the ferrous members of the two magnetic assemblies as they pass each other as the magnet assemblies rotate relative to the electromagnetic assembly.

摘要： An electric motor including a driven element, a magnet assembly and a driving element. The driven element being driven in a direction of movement. The magnet assembly is includes first and second magnets each having first and second magnetic poles. The first magnetic pole of the first magnet and the first magnetic pole of the second magnet being proximate to each other and facing each other thereby defining a first magnetic zone therebetween. The first magnetic poles all being similar, and the second magnetic poles all being similar. The driving element is proximate to the magnet assembly, producing a magnetic field within the driving element that is primarily orthogonal to the direction of movement.

摘要： A loudspeaker assembly comprises a casing with a diaphragm loudspeaker mounted in the casing. A phase plug is mounted in the casing adjacent the diaphragm loudspeaker. The phase plug has a central cone with a longitudinal axis extending from an input end adjacent the diaphragm loudspeaker to an output end with its base at the input end tapering to an apex at the output end. A plurality of vanes extend radially outwardly from the central cone with the plurality of vanes being thickest at the input end and progressively thinning toward the output end. Radially outward edges of the plurality of vanes are twisted relative to the longitudinal axis with the degree of twist being progressively greater with increasing proximity to the output end. The plurality of vanes tapers in width along their longitudinal extent from the input end to the output end.
