Abstract: A shallow speaker and a method of manufacture for the shallow speaker. The method of assembly uses two different alignment jigs at two different stages of the assembly to ensure alignment of the speaker components. During manufacture, a subassembly of components is created in the speaker frame, and then removed along with the first alignment jig. A second alignment jig is then placed in the speaker, and the bobbin and voice coil added. The subassembly is then connected to the frame, and the voice coil connected to the external connection terminal. Finally, the cone and dust cap are installed.

Abstract: A passive acoustic radiator has a forward radiating element and a reverse radiating element each defined by a front face and an opposed rear face. A forward diaphragm is coupled to a forward surround defined by an annular raised side coinciding with the forward front face and an opposed annular trough side coinciding with the forward rear face. A reverse diaphragm is coupled to a reverse surround defined by an annular raised side coinciding with the reverse front face and an opposed annular trough side coinciding with the reverse rear face. The forward radiating element and the reverse radiating element are attached to each other with the forward rear face being in an abutting relationship to the reverse rear face. An annular open space is defined at least partially by the respective trough sides of the forward and reverse radiating elements.

Abstract: A grille attachment for a loudspeaker is disclosed. A grille retainer is defined by a retention lip portion, a radial rim interface portion, and a hinge portion. The radial rim interface portion is in an abutting relationship with a flange radial mounting surface of the loudspeaker basket. The hinge portion connects the retention lip portion and the radial rim interface portion. The retention lip portion extends toward a flanged rim of the speaker basket, and defines an inner retention surface that is opposed to a flange circumferential surface. A grille extends across the griller retainer and is defined by a grille body and a grille rim that is circumferentially disposed and extending from the grille body. The grille rim is interposed between the flange circumferential surface and the inner retention surface, with the retention lip portion exerting a radial compressive force against the grille rim.

Abstract: An apparatus for mounting a loudspeaker unit to a structure is disclosed. A primary mounting bracket is defined by an arcuate center section and a pair of opposed arms extending therefrom. There is at least one open groove and at least one substantially coextensive track spanning the arcuate center section. Each of the arms include a circular planar bearing structure rotatably engageable to a corresponding one of bracket coupling platforms on an enclosure of the loudspeaker unit. A tab defining at least one mounting hardware hole in axial alignment with open groove substantially throughout its length is in a guided sliding engagement with the track. The enclosure of the loudspeaker unit is rotatable about a first axis extending between the arms of the primary mounting bracket and about a second axis defined by a radial center of an arc corresponding to a travel path of the tab along the track.

Abstract: A loudspeaker includes a circular damper, a cone, and a cylindrical bobbin. The circular damper may include a centrally disposed cone attachment protuberance and a peripherally disposed top plate attachment section. The cone may have a central inner portion that may be attached to the cone attachment protuberance of the damper. The cone may be attached to the cylindrical bobbin, which may have a voice coil coupled thereto.
