Publication number: 20120237069Abstract: An electrostatic loudspeaker (ESL) assembly providing curvature in two directions for improved dispersion of sound waves. The ESL comprises at least one stator panel, a flexible diaphragm and a spacer that impedes contact between the stator panel and the diaphragm. The stator is formed from a material that comprises an array of apertures. Furthermore, the material can be annealed. The material temper, along with the aperture geometry and patter, affect the stretchability of the material. The two-axis curved structure enables a compact form of ESL to be realized, including bookshelf type loudspeakers whereas all known commercial units are comparable in height to that of a human listener. The individual curved ESL panels can also be readily combined to create larger transducer assemblies including omni-directional units.Type: ApplicationFiled: April 20, 2012Publication date: September 20, 2012Inventor: Murray R. HARMAN

Patent number: 8259980Abstract: An adjustable tweeter assembly is provided to allow a tweeter to be directionally oriented to a selected position. The assembly includes a base, a bowl, and a cup, which are nested together so that the bowl is sandwiched between the base and the cup for movement therebetween. The tweeter is mounted in the bowl which can be rotated and pivoted relative to the cup and to the base. A fastener extends through the cup, the bowl, and the base, and through a leaf spring so as to provide a compressive or clamping force between the base, the bowl, and the cup. The tweeter is rotatable 360° and pivotal approximately 90°.Type: GrantFiled: August 27, 2008Date of Patent: September 4, 2012Assignee: Three Amigos LLCInventors: Ronald D. Maurer, Sean P. McDermott, Richard P. Apgar

Patent number: 8224001Abstract: A line array speaker provides highly uniform frequency response throughout a wide listening field, while also reducing distortion and improving fidelity, clarity, and output level. In a symmetrical embodiment, central apertures are straddled by a sequential pairs of sets of apertures. The straddling pairs emit frequencies in the next lower frequency band relative to the frequency band of the immediately preceding frequency band apertures. In an asymmetrical embodiment, sequential frequency bands are emitted by adjacent sets of apertures rather than straddling pairs of sets of apertures. Each of the apertures may be a loudspeaker cone, one or more straight slots, one or more arbitrarily curved slots, one or more arbitrarily angled slots, one or more holes or the mouth of a horn. The speaker may have a front baffle which is a flat panel or multiple facets arranged in one or multiple recesses across a front of the speaker.Type: GrantFiled: December 21, 2007Date of Patent: July 17, 2012Inventor: Jon J. Waller

Patent number: 8175304Abstract: A loudspeaker configuration capable of generating stereophonic sound separation from relatively loudspeaker drivers that are not necessarily widely separated. For example, such a loudspeaker configuration can be used to generate relatively good sound separation from a single chassis, such as a single speaker box, a boom box, a clock radio or the like. This can advantageously save space in many environments. One embodiment uses four mid-tweeter speaker drivers and a bass driver. The four mid-tweeter speaker drivers are arranged facing outward approximately 90 degrees apart from each other. A speaker driver facing the listener reproduces a mid channel signal, for example, L+R. A speaker driver facing away from the listener reproduces the same mid channel signal or a delayed version of the mid channel signal. A left facing speaker reproduces a side channel, for example, L?R. A right facing speaker reproduces a side channel, for example, R?L.Type: GrantFiled: February 12, 2008Date of Patent: May 8, 2012Inventor: Donald J. North

Patent number: 8170223Abstract: A loudspeaker is provided for receiving an incoming electrical signal and transmitting an acoustical signal that is directional and has a substantially constant beamwidth over a wide frequency range. The loudspeaker may include a curved mounting plate that has curvature over a range of angles. The loudspeaker may include an array of speaker drivers coupled to the mounting plate. Each speaker driver may be driven by an electrical signal having a respective amplitude that is a function of the speaker driver's respective location on the mounting plate. The function may be a Legendre function. Alternatively, the loudspeaker may include a flat mounting plate. In this case, the respective electrical signal driving each speaker may have a phase delay that virtually positions the speaker onto a curved surface.Type: GrantFiled: January 4, 2010Date of Patent: May 1, 2012Assignee: Harman International Industries, IncorporatedInventor: D. Broadus Keele, Jr.

Patent number: 8155370Abstract: An audio system utilizes a method for detecting and adjusting a sound field effect thereof. The audio system includes a first speaker and a second speaker. The first speaker is used to emit a first sound signal, and the second speaker is used to emit a second sound signal. The method for adjusting the sound field effect includes the steps of detecting a specific position and adjusting the first speaker or the second speaker based on the specific position to focus the first sound signal and the second sound signal on the specific position.Type: GrantFiled: January 19, 2009Date of Patent: April 10, 2012Assignee: Asustek Computer Inc.Inventors: Shou-Hsiu Hsu, Kuo-Hsun Huang
