Dec 20, 2000

Appl. No.:

09/745179

Inventors:

Kelly Q. Kay - Chicago IL
Mark W. Gilbert - Park Ridge IL

Assignee:

Shure Incorporated - Niles IL

International Classification:

H04R 2500

US Classification:

381175, 381174, 381191

Abstract:

A microphone assembly comprising a housing, the housing including an upper lip, a silicon backplate having a top portion, a bottom portion, an annular side portion, a silicon spacer integrally formed with the backplate and comprising at least one protrusion extending from and integral to the top portion of the silicon backplate, the spacer further comprising an insulating layer, such as silicon dioxide or a fluoropolymer. A plurality of openings extend from the top portion of the backplate to the bottom portion of the backplate. A single diaphragm, comprised of metallized polymer film, acts as both a protective environmental barrier and a sensing electrode of a capacitive electroacoustic sensing transducer. A metal ring is positioned against the upper lip of the metal housing. The diaphragm is adhesively affixed to the ring, and the ring, in cooperation with the upper lip and a spring, secure the diaphragm against the insulating layer of the spacer.

Assignee:

Shure Incorporated - Niles IL

International Classification:

H04R 300

US Classification:

381 92, 381122, 381357, 367178

Abstract:

The invention provides method and apparatus that utilize a plurality of port sub-arrays, in which each port sub-array comprises a plurality of acoustical ports. The ports of each port sub-array are spaced so that each port sub-array responds to acoustical signals that are generated by acoustical sources within an associated frequency range. In an embodiment of the invention, associated frequency ranges are related in a harmonic manner, in which each port sub-array corresponds to different frequency octaves. The associated frequency range is a portion of the total frequency range of an acoustical system. Received acoustical signals from each of the port sub-arrays are coupled over acoustical pathways and are converted into electrical signals by capsules that may be mounted in a capsule mounting. The electrical signals may be filtered, such as to reduce spatial aliasing, and post processed to further enhance the characteristics of the signals.

Appl. No.:

11/623846

Inventors:

Mark W. Gilbert - Park Ridge IL, US
Gregory H. Canfield - Niles IL, US

Assignee:

Shure Acquisition Holdings, Inc. - Niles IL

International Classification:

H04M 3/42

US Classification:

37920201

Abstract:

The invention provides a digital automixer system that includes a master processing unit and at least one non-master processing unit that are interconnected. The non-master processing unit obtains a first microphone signal and determines a first basic level measurement and a network submix audio signal. The master processing unit obtains a second microphone signal and determines a second basic level measurement, and obtains the first basic level measurement and the network submix audio signal from the non-master processing unit. The master processing unit further forms a final mix audio signal from the second microphone signal and the network submix audio signal and determines a gating control signal for the digital automixer system. The master processing unit may also delay the second basic level measurement to compensate for a network delay. The invention also provides a digital automixer system that includes a plurality of master processing units.

6/869193

Inventors:

Stephen D. Julstrom - Chicago IL
Mark W. Gilbert - Des Plaines IL

Assignee:

Shure Brothers Incorporated, Inc. - Evanston IL

International Classification:

H03M 0000

US Classification:

341143

Abstract:

An adaptive delta modulation circuit having an analog adaptation circuit and an integrator circuit. The adaptation circuit exponentially converts a voltage which is proportional to the average of a time duration of an overload control signal to an adaptation current which is averaged and converted to an adaptation voltage. An integrator circuit includes a sole switch which shorts to ground a circuit point for generating an analog signal formed of line segments; each segment has a slope magnitude controllable by the adaptation voltage.

International Classification:

H04R 1/32

Abstract:

Embodiments include a microphone array comprising a first plurality of directional microphone elements arranged in a first cluster formed by directing a front face of said microphone elements towards a center of the first cluster, and a second plurality of directional microphone elements arranged in a second cluster formed by directing a front face of said elements away from a center of the second cluster, wherein the first cluster is disposed vertically above the second cluster. Also provided is a microphone comprising a first microphone array comprising a plurality of directional microphone elements arranged in close proximity to each other and configured to capture near-field sounds within a first range of frequencies, and a second microphone array disposed concentrically around the first microphone array, the second array comprising a plurality of omnidirectional microphone elements configured to capture near-field sounds within a second range of frequencies higher than the first range.
