20090003632 | SINGLE MAGNET COAXIAL LOUDSPEAKER - A coaxial loudspeaker for reproducing an electrical sound signal is provided. The loudspeaker has a magnetic driver assembly with a first annular slot and an opposed, coaxial second annular slot, each establishing a permanent magnetic field therein from a single magnet. Independently driven first and second voice coils are positioned within the respective one of the first and second annular slots, each being connected to a transducer element. | 01-01-2009 |
20090185694 | LOUDSPEAKER INTERCONNECT TERMINAL - A loudspeaker interconnect terminal for selectively coupling a plurality of loudspeaker drivers to a monophonic source and a stereophonic source. The terminal includes a body defined by a first side and a second side, and first and second sets of input terminals disposed on a respective one of the first and second sides. The terminal also includes an electrical switch with an actuator having a first position and a second position. The first set of input terminals are connected to the corresponding one of the second set of input terminals and a switch cover coupled to the actuator conceals at least a part of the first set of input terminals with the actuator in the first position. | 07-23-2009 |
20090310813 | INTERCHANGEABLE MAGNET LOUDSPEAKER - A moving coil loudspeaker has an interchangeable magnet assembly with a plurality of interchangeable magnet segments configured to be circumferentially disposed about a voice coil within the loudspeaker. Heat sink members can be arranged in between the magnet segments to absorb excess heat generated during operation of the loud speaker. In one embodiment, the magnet assembly has at least one annular magnetic member made up of the plurality of magnet segments, a plurality of heat sink members disposed in between the magnet segments, an annular first plate adjacent a first side of the annular magnetic member, and a yoke member having a second plate adjacent a second side of the annular magnetic member and a central cylindrical portion configured to pass through a central opening in the annular magnetic member. | 12-17-2009 |
20100008522 | Interchangeable Bar Loudspeaker System - There is provided a speaker connector including first and second speaker elements each having an inward face, an opposing outward face, and an engagement wall extending between the inward and outward faces. The speaker elements are connectable to the first and second speakers, respectively. A connector housing includes first and second end faces disposed on opposing sides of a housing medial portion. First and second inner walls extend inwardly from the first and second end faces, respectively, to define first and second housing recesses. The first and second inner walls are configured to engage with the engagement wall of the respective speaker elements with the first speaker element being received within the first housing recess and the second speaker element being received within the second housing recess. | 01-14-2010 |
20120257783 | SINGLE MAGNET COAXIAL LOUDSPEAKER - A coaxial loudspeaker for reproducing an electrical sound signal is provided. The loudspeaker has a magnetic driver assembly with a first annular slot and an opposed, coaxial second annular slot, each establishing a permanent magnetic field therein from a single magnet. Independently driven first and second voice coils are positioned within the respective one of the first and second annular slots, each being connected to a transducer element. | 10-11-2012 |
20130251187 | UNIVERSAL ANGLE LOUDSPEAKER BRACKET - 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. | 09-26-2013 |
20140233786 | GRILLE ATTACHMENT FOR LOUDSPEAKER - 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. | 08-21-2014 |
20150195629 | PASSIVE RADIATOR - 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. | 07-09-2015 |
