20080310661 | Loud speaker group assembled from a plurality of loud speakers with snap-on connections - A loud speaker group includes loud speakers which are equipped with joints on their front sides, and on their back sides, each is equipped with a mount for connectors with which the individual loud speakers can be connected to one another. For facilitating their assembly, the mount comprises two legs that are attached to the back side of the loud speaker box and enclose a channel in which the connector is displaceably movable. At its one end the mount has a row of holes for receiving a pin that extends through a hole on one end of a connector belonging to the adjacent loud speaker box and has at its other end a manually actuated spring-loaded snap-in pin. The snap-in pin is insertable through another hole disposed in front of the other end of the connector. One guide unit on each side of the snap-in pin limits the channel and are arranged perpendicular to the direction of movement of the connector and form guides for the connector. The loud speaker boxes are pre-assembled on the ground and then automatically self-adjust to the desired angle position when they are lifted to their work place. | 12-18-2008 |
20090175476 | SPEAKERBAR - The present invention introduces a speakerbar which mounts above or below a flat screen TV and reproduces the surround sound experience normally associated with speakers placed in five to seven separate locations around the room. | 07-09-2009 |
20100002899 | VOICE CONFERENCE SYSTEM - A voice conference system capable of realizing a talk session with an unbounded feeling of presence in session in response to positions of conferees who are seated at mutual voice conference devices is provided. A conferee | 01-07-2010 |
20110026750 | DIAPHRAGM AND LOUDSPEAKER USING THE SAME - A diaphragm includes a diaphragm matrix and at least one reinforcing structure composited with the diaphragm matrix. The at least one reinforcing structure includes at least one freestanding carbon nanotube structure. A loudspeaker includes a magnetic circuit defining a magnetic gap; a bobbin located in the magnetic gap; a voice coil wound on the bobbin; and a diaphragm. The diaphragm includes an inner rim fixed to the bobbin a diaphragm matrix, and at least one reinforcing structure composited with the diaphragm matrix. The at least one reinforcing structure includes at least one freestanding carbon nanotube structure. | 02-03-2011 |
20120008812 | LOUDSPEAKER - A loudspeaker includes a two-dimensional array of non-housed individual speakers having flat shapes. The non-housed individual speakers are accommodated within a flat housing, the depth of the housing being smaller than 5 cm, for example. Non-housed individual speakers used are advantageously headphone capsules and/or miniature loudspeakers having diaphragm diameters of less than 5 cm. | 01-12-2012 |
20120308065 | SOUND BAR - A sound bar includes a housing, a rotary member, first and second speaker boxes, and a gear mechanism. The rotary member is rotatable with respect to the housing. The first and second speaker boxes are slidable with respect to the housing, respectively. The first and second speaker boxes are disposed at opposite end portions of the housing in a lengthwise direction of the housing, respectively. The gear mechanism is disposed between the rotary member and the first and second speaker boxes. The gear mechanism is configured to slide both the first and second speaker boxes with respect to the housing in opposite directions of the housing along the lengthwise direction of the housing in response to a rotational movement of the rotary member. | 12-06-2012 |
20130039522 | FLAT SPEAKER DEVICE AND METHOD OF FABRICATING THE SAME - A flat speaker device includes a first housing assembly and a speaker assembly. The method of fabricating the flat speaker device has steps of combining a first upper layer with a first frame; combining a first flat speaker with the first upper layer; combining a first lower layer with the first frame and the first flat speaker; placing a lower cover layer under the first lower layer; placing a upper cover layer over the first upper layer; combining the upper cover layer, the first upper layer, the first frame, the first flat speaker, the first lower layer and the lower cover layer; forming a pocket on the upper cover layer; and mounting a printed circuit board in the pocket. | 02-14-2013 |
20130259284 | Speaker-box - Disclosed is a speaker-box. The speaker-box includes a case, a speaker unit received in the case and a heat radiating portion attached on the base and directly connecting to a part of the speaker unit for dissipating the heat generated by the speaker unit. | 10-03-2013 |
20140205126 | ADJUSTABLE SPEAKER RIGGING SYSTEM - Opposing strings of pivotally coupled rigid members attach to opposing sides of tapered speaker cabinets in an array of speaker cabinets. Attachment is made near the front cabinet edges and a rear adjustable coupling string of brackets and adjustable couplings connect to the rear of the tapered speaker cabinets. Actuation of the adjustable couplings enables continuous adjustment of the angular relationships of the speaker cabinets while under load. A three-point fly frame coupling is provided. A three-point dolly coupling is provided. | 07-24-2014 |
20150086056 | Speaker Device - A speaker device is provided with: a housing having a box body and a lid for closing the box body, a partition wall configured to separate the inside of the housing to form a plurality of spaces, a plurality of speaker units accommodated in the spaces, respectively, a wiring board configured to electrically connect the speaker units to the outside, and an elastic member provided between the partition wall and the lid, and closing the gap with the periphery of the wiring board in a state that the elastic member holds the wiring board. | 03-26-2015 |
20150110325 | Speaker and Speaker Net - A speaker includes: one or more speaker units; a cabinet accommodating the one or more speaker units; and a speaker net mounted on one of the cabinet and at least one of the one or more speaker units so as to cover a sound emitting surface of each of the at least one of the one or more speaker units. The speaker net includes: a frame surrounding the sound emitting surface of each of the at least one of the one or more speaker units; and a sheet member stuck to the frame to cover the sound emitting surface of each of the at least one of the one or more speaker units. The frame being formed with at least one through hole establishing communication between (i) a space between the frame and the cabinet and (ii) a space outside the speaker. | 04-23-2015 |
