Patent number: 7699138Abstract: A flangeless mounting system, suitable for in-wall speakers and other objects, includes a panel that replaces a substantial section of wallboard instead of being installed behind the wallboard. In preferred embodiments a rim extends outwardly from a first surface of the panel by a distance of less than ½ inch, and preferably by only ? inch or even 1/16 inch. The face of the object can be quite large, up to 40 in2 or more, and still be relatively small with respect to the panel. Panels are contemplated that have a width at least two, three or more times that of the face of the object, and along with optional wings are wider than the stud separation in the wall.Type: GrantFiled: December 4, 2006Date of Patent: April 20, 2010Assignee: Dana InnovationsInventors: Scott Struthers, Ray Call, Todd Ryan

Patent number: 7686129Abstract: A horn and a loudspeaker employing the horn are disclosed that include a body having a throat that expands outwardly to a mouth such that a first interior area defined by the throat is smaller than a second interior area defined by the mouth. A plurality of raised surface areas is located on an interior surface of the body. The raised surface areas extend into a hollow interior defined by the body a predetermined distance and are utilized to channel sound waves through the body and out the mouth.Type: GrantFiled: August 30, 2007Date of Patent: March 30, 2010Assignee: Klipsch LLCInventor: Rogelio Delgado, Jr.

Patent number: 7669692Abstract: A sound diffuser includes a front plate defining a plurality of sound exit holes. An outer frustoconical wall extends from the front plate, the outer frustoconical wall decreasing in diameter from the front plate. An inner frustoconical wall extends from the outer frustoconical wall toward the front plate, the inner frustoconical wall decreasing in diameter toward the front plate and defining a sound entry opening spaced apart from the front plate. A plurality of legs are coupled to at least one of the front plate and the outer frustoconical wall, the legs extending away from the front plate to contact a speaker cover. First and second straps operatively extend from the front plate, the first strap having a distal end with a fastener for connection to a speaker case. The second strap also has a distal end with a fastener for connection to the speaker case.Type: GrantFiled: January 21, 2008Date of Patent: March 2, 2010Inventor: James W. Hawkins

Publication number: 20100032232Abstract: A speaker device of a video display apparatus which realizes a high quality sound by improving a bass property even in the case that an enclosure unit has a smaller internal volume than that a speaker unit should basically have is provided. The speaker device includes at least one speaker unit, an enclosure unit which contains and supports the speaker unit and has an opening formed on a side surface thereof, and a cover which closes and seals the opening of the enclosure unit and is movable by an air movement inside the enclosure unit. The cover is formed of a material which is not permeable to air, and this material may be at least one of resin, textile, vinyl and paper. The cover may be formed of a foam rubber of an elastomeric system.Type: ApplicationFiled: July 17, 2009Publication date: February 11, 2010Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventor: Soo-chan LIM

Publication number: 20100002894Abstract: A MEMS device includes a vent hole structure and a MEMS structure disposed on a same side of a substrate. The vent hole structure adjoins the MEMS structure with an etch stop structure therebetween. The MEMS structure includes a chamber, the vent hole structure includes a metal layer having at least a hole thereon as a vent hole to connect the chamber of the MEMS structure through the etch stop structure. Accordingly, the MEMS device has a lateral vent hole. Furthermore, as the vent hole structure and the MEMS structure are disposed on the same side of the substrate, the manufacturing process is convenient and timesaving.Type: ApplicationFiled: July 3, 2008Publication date: January 7, 2010Inventors: Bang-Chiang Lan, Li-Hsun Ho, Wei-Cheng Wu, Hui-Min Wu, Min Chen, Chien-Hsin Huang, Ming-I Wang

Patent number: 7624839Abstract: A compact loudspeaker enclosure combines planar type devices for high frequency sound reproduction and cone type active devices for low frequency sound reproduction. The low frequency cone type transducers are mounted in baffles between forward and rear enclosed spaces and thus do not directly radiate into the environment. The first enclosed space is acoustically coupled to the environment by the planar device which is mounted between the first enclosed space and the environment with one major face mounted to radiate either directly into the environment or to be horn loaded. The planar operates as a passive radiator to the LF devices at low frequencies and an active device above a crossover frequency.Type: GrantFiled: May 12, 2006Date of Patent: December 1, 2009Inventor: Curtis E.
