20140305734 | FLIP OUT DOG LEG MOUNTABLE CEILING SPEAKER ENCLOSURE - A manually operated flip dog mountable ceiling speaker enclosure, for ceiling or other panel installation, provides a plurality of flip dogs mounted tangentially on an annular flange around an opening of a speaker can and operated by either pulling on an actuator to create a cam-driven rotation to a radial alignment and a downward dog movement to a ratcheted clamping position, or by first rotating the manual actuator to rotate the dog and then pulling the actuator to pull the dog down into a ratcheted clamping position. Ratchet points on the dog are urged into ratchet points on a wall by a releasable biasing member. Three embodiments are illustrated. | 10-16-2014 |
20130089210 | END OF BRANCH MODULE SYSTEM - An end-of-branch (EOB) module system for an audio signal distribution system having a wired trunk and a plurality of wired branches extending communicatively from such trunk, the EOB module system including: a plurality of EOB modules including one EOB module electronically coupled at each distal end of each branch and trunk of the audio signal distribution system, where each EOB module of the plurality of EOB modules has a unique address together forming a plurality of unique addresses; a test system able to send a test carrier signal encoded with any one unique address of the plurality of unique addresses at a time onto the trunk; and a switch within each EOB module, responsive to its unique address to place an end-of-line (EOL) load on its respective branch or trunk, and where power for operation of each EOB module is provided by rectification of the test signal. | 04-11-2013 |
20130016864 | Lighting and Audio Communication System - A lighting and communication system with a horn enclosure for recessed ceiling panel or wall mounting, including a speaker with a horn expansion area to direct sound waves from the speaker to a horn enclosure front, at least one light enclosure located within the horn enclosure, the light enclosure defining a light cavity which is separated from said horn expansion area, with a light source inside the light cavity. The light source can be an LED array, which is capable of displaying text, colors or patterns in response to a control system signal. | 01-17-2013 |
20120250931 | SHALLOW SPEAKER - An improved shallow speaker is disclosed having a molded diaphragm with an outer, depending, annular cylindrical subcone that connects to a channel formed in the outer perimeter of the spider. Embodiments for round and cornered (polygonal, etc.) speakers are provided. The top plate has a raised outer annular portion for receiving an annular spider flange with or without screw holes for clamping the inner spider flange with a spider ring. In the cornered speaker embodiments, flanges extend from the cylindrical portions to the cornered portions including from a diaphragm inner glue flange over the depressed central portion and from the annular cylindrical subcone both outwardly and inwardly to top diaphragm portions. Routing of the tinsel may be through one or more openings in the annular cylindrical subcone and along the diaphragm inner surfaces, with channels in or on those surfaces for securely routing the tinsel. | 10-04-2012 |
20100226512 | PRESENTATION AUDIO SYSTEM - A presentation audio system with two dual-mode, dual-channel, wireless IR microphone/controllers that concurrently transmit multiplexed audio and command IR signals to IR sensors communicating to an amplifier that sends amplified audio to one or more speakers, responsive to the received commands. Each wireless IR microphone/controller includes a microphone and controller in a housing with manual controls and separate redundant groups of transmitting IR LEDs. The amplifier is controlled as to volume, audio sources selected, and control closure operation. First mode controls the audio of the IR microphone/controller that is set in the first mode and second mode controls all audio sources in the system. One manual control is a control closure that may be used to initiate a building alarm or for other purposes. A headset microphone jack enables use of the IR microphone/controller as an IR transmitter. A dual recharger usable vertically or horizontally is included. | 09-09-2010 |
20090067663 | OMNI-DIRECTIONAL SPEAKER LAMP - A speaker, having a diaphragm with a central opening and further having a pole piece, including a first sound dispersion element extending from the pole piece through the central opening of the diaphragm and further extending beyond the diaphragm wherein the first sound dispersion element has a larger transverse perimeter distal the pole piece than proximal the pole piece; and no support structures for the first sound dispersion element are located radially external to said first sound dispersion element. The speaker may be integrated with a lamp using a support structure. A second sound dispersion element may be used. A rod, used as a conduit, coupling, and/or support, may extend coaxially with the first sound dispersion element, interior thereto, and to a point beyond the diaphragm. The audio signal for the speaker may be supplied by a wireless link. The speaker and lamp may be configured for a ceiling fan. | 03-12-2009 |
20080280501 | ADJUSTABLE TERMINAL BLOCK - An adjustable terminal is disclosed having a plurality of electrical contacts electrically coupled between a corresponding number of pair-wise electrically-coupled input terminals and output terminals. A plurality of mechanically coupled jumpers are operable to pair-wise jump the electrical contacts to reconfigure the adjustable terminal variously for bi-amplifier output, parallel output, and series output at said output terminals. A housing is disclosed having support for the electrical contacts and for the jumpers, as well as labels for inputs, outputs, and current configuration. | 11-13-2008 |
20080279415 | SPEAKER CONE AND DUST CAP ASSEMBLY - A speaker cone and dust cap assembly for a speaker is disclosed having an acoustic web for a dust cap that has a lower surface with a convex shape; a speaker cone with an end web, sized and arranged to close the first end of the former distal the magnet assembly of the speaker, the end web comprising a concave surface shaped conformally with a central portion of the lower surface of the acoustic web; and having the end surface of the end web fixed to the central portion of the lower surface of the acoustic web over substantially the entire surface of the end surface of the end web. The speaker cone may have a cylindrical extension wrapping the first end of the former. The cylindrical extension and the first end of the former may have aligned vents. | 11-13-2008 |
20080279413 | SPEAKER SUPPORT SYSTEMS - A speaker support system, adapted to prevent destructive resonance between a speaker and a speaker cabinet, comprising a vibration damper, a vibration transferer, and a connector. The speaker support prevents primary-mode resonance from building up to damaging levels in a speaker cabinet. | 11-13-2008 |
