Patent number: 9002036Abstract: A microphone system has a primary microphone for producing a primary signal, a secondary microphone for producing a secondary signal, and a selector operatively coupled with both the primary microphone and the secondary microphone. The system also has an output for delivering an output audible signal principally produced by one of the to microphones. The selector selectively permits either 1) at least a portion of the primary signal and/or 2) at least a portion of the secondary signal to be forwarded to the output as a function of the noise in the primary signal.Type: GrantFiled: April 24, 2012Date of Patent: April 7, 2015Assignee: Invensense, Inc.Inventors: Kieran P. Harney, Jason Weigold, Gary Elko

Patent number: 8351632Abstract: A microphone system has a base coupled with first and second microphone apparatuses. The first microphone apparatus is capable of producing a first output signal having a noise component, while the second microphone apparatus is capable of producing a second output signal. The first microphone apparatus may have a first back-side cavity and the second microphone may have a second back-side cavity. The first and second back-side cavities may be fluidly unconnected. The system also has combining logic operatively coupled with the first microphone apparatus and the second microphone apparatus. The combining logic uses the second output signal to remove at least a portion of the noise component from the first output signal.Type: GrantFiled: August 24, 2009Date of Patent: January 8, 2013Assignee: Analog Devices, Inc.Inventors: Kieran P.

Publication number: 20060188089Abstract: A system and method of digitally modeling and significantly reducing the direct coupling between a telephone appliance loudspeaker and microphone employs a handset microphone in a phone appliance, such as, for example, a speakerphone, as a reference channel along with the speakerphone microphone to reduce the direct coupling between the speakerphone loudspeaker and the speakerphone microphone. Using an analog adaptive echo cancellation scheme, the sensitivity and dynamic range of a telephone device microphone to speech from talkers in an enclosure but not from signals emitted by a telephone loudspeaker are enhanced. Nonlinear distortions produced by a telephone appliance loudspeaker are measured by a telephone appliance handset microphone and used in a feedback subsystem, e.g., network, to reduce nonlinear distortions in the telephone appliance loudspeaker and loudspeaker driving circuit.Type: ApplicationFiled: February 18, 2005Publication date: August 24, 2006Inventors: Eric Diethorn, Gary Elko

Publication number: 20050244014Abstract: A communication device includes a speaker, a microphone, and a processor connected to the speaker and the microphone. The processor is arranged for calculating ambient temperature by playing a test sound on the speaker, measuring a transit time of the test sound from the speaker to the microphone, and determining the ambient temperature from the measured transit time. A method of calculating ambient temperature by using a communications device having a speaker, a microphone and a processor is also disclosed. The method can be used for monitoring ambient temperatures of machinery and for detecting fire conditions.Type: ApplicationFiled: April 30, 2004Publication date: November 3, 2005Inventors: Gary Elko, Eric Diethorn, Valentine Matula

Publication number: 20050123149Abstract: A microphone array-based audio system that supports representations of auditory scenes using second-order (or higher) harmonic expansions based on the audio signals generated by the microphone array. In one embodiment, a plurality of audio sensors are mounted on the surface of an acoustically rigid sphere. The number and location of the audio sensors on the sphere are designed to enable the audio signals generated by those sensors to be decomposed into a set of eigenbeams having at least one eigenbeam of order two (or higher). Beamforming (e.g., steering, weighting, and summing) can then be applied to the resulting eigenbeam outputs to generate one or more channels of audio signals that can be utilized to accurately render an auditory scene. Alternative embodiments include using shapes other than spheres, using acoustically soft spheres and/or positioning audio sensors in two or more concentric patterns.Type: ApplicationFiled: January 10, 2003Publication date: June 9, 2005Inventors: Gary Elko, Robert Kubli, Jens Meyer

Publication number: 20050037782Abstract: The present invention is a desktop speakerphone having a base-station and a detachable microphone pod. The base-station includes standard telephone components, as well as a wireless receiver and a housing for a detachable microphone pod. The detachable pod contains at least one microphone and a wireless transmitter. When the pod is attached to the base-station, and the conference mode of operation is activated, the pod microphone's audio signal goes directly to base-station audio circuitry via a wired connection. When the pod is detached and the conference mode activated, the pod microphone's audio signal now goes via the pod's wireless transmitter to the base-station's wireless receiver. This detached, wireless mode allows the microphone to be positioned anywhere in the room, thereby improving the quality of transmitted speech by increasing the speech-signal-to-room-noise ratio, and lessening the potential for room echo by reducing the acoustic coupling between base-station loudspeaker and pod microphone.Type: ApplicationFiled: August 15, 2003Publication date: February 17, 2005Inventors: Eric Diethorn, Gary Elko, Biing-Hwang Juang, James West
