Patent number: 8132642Abstract: Normally a speaker is used by attaching to a sealed or semi-sealed cabinet so that vibration generated at the front and the back of a diaphragm does not mutually interfere. Therefore, a certain depth and a volume are necessary, and in a limited location such as a front panel of a device, there is a case that it cannot be attached to the most suitable position for a listener. As a means to solve that, a method that a speaker sound at a distant position is led to a front panel by a waveguide is practically used. However, still it has limitations in depth and attaching position, and good results cannot be obtained also in efficiency. A speaker is attached so that a sound generated at the front of the speaker attached to a cabinet is led to a plane such as a front panel of a device by a waveguide, and the opening surface of the waveguide is almost perpendicular to the plane.Type: GrantFiled: September 12, 2008Date of Patent: March 13, 2012Assignee: M.

Patent number: 7684574Abstract: A reflective loudspeaker array is cooperatively operable with an acoustically reflective planar surface to provide a constructive combination of direct and reflected sound waves that produces a uniform sound field. The uniform sound field provides a controlled sound field in the vertical and horizontal direction, and also provides uniformity from distances close to the reflective loudspeaker array to far way. The direct and reflected sound waves are advantageously and constructively combinable to generate a focused beamwidth of soundwaves. The reflective loudspeaker array includes a plurality of loudspeakers coupled to a surface of the reflective loudspeaker array. The surface may be formed to include at least one curve with a radius of curvature.Type: GrantFiled: March 8, 2006Date of Patent: March 23, 2010Assignee: Harman International Industries, IncorporatedInventors: D. Broadus Keele, Jr., Douglas J. Button

Patent number: 7668331Abstract: An improved-fidelity speaker system is presented. The sound system includes a frame and a pair of matching speakers. The frame is formed to hold a first speaker and a second speaker, each having a front side, a back side, and central axis. When attached with the frame, the two speakers are substantially aligned along their central axes in a configuration selected from a group consisting of being mounted in the frame such that the front sides of the speakers are facing away from each other, and being mounted in the frame such that the front sides of the speakers are facing towards each other. When the speakers are operated in unison, a sound wave is generated and pushed outward from the frame and approximately radially from the central axes of the speakers in up to 360 degrees, expanding outward about a plane approximately perpendicular to the central axes.Type: GrantFiled: October 7, 2005Date of Patent: February 23, 2010Inventor: Wailit Yen

Patent number: 7606379Abstract: 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.Type: GrantFiled: November 26, 2008Date of Patent: October 20, 2009Assignee: Mitek Corp, Inc.Inventors: Lloyd Ivey, Paul Schleipfer, Simon Broadley
