Patent number: 10897669Abstract: Aspects of the present disclosure provide multi-layer microphone protection for any apparatus that captures sound. The apparatus includes an enclosure defining a first cavity. A microphone element is coupled to the first cavity. The microphone element comprises a microphone sensor and a microphone cavity. A first, outer protective layer is disposed at an outer end of the first cavity, closer to the external environment. A second, inner protective layer is disposed between an inner end of the first cavity and the microphone element. The second, inner protective layer may protect the microphone sensor from particles or liquids that may have passed through the first protective layer. The first and second layers may have different acoustic properties.Type: GrantFiled: August 13, 2018Date of Patent: January 19, 2021Assignee: BOSE CORPORATIONInventors: Martin David Ring, David-Michael Lozupone, Edwin C. Johnson, Jr., David Glenn Meeker, Michael Ciufo

Patent number: 10074354Abstract: In an active noise reducing headphone, a signal processor applies filters and control gains of both the feed-forward and feedback active noise cancellation signal paths. The signal processor is configured to apply first feed-forward filters to the feed-forward signal path and apply first feedback filters to the feedback signal path during a first operating mode providing effective cancellation of ambient sound, and to apply second feed-forward filters to the feed-forward signal path during a second operating mode providing active hear-through of ambient sounds with ambient naturalness.Type: GrantFiled: March 29, 2016Date of Patent: September 11, 2018Assignee: Bose CorporationInventors: Daniel M. Gauger, Jr., Ricardo F. Carreras, Jason Harlow, Neil Adam Ranney, Martin David Ring, Roman Sapiejewski, Vishu Singh

Patent number: 9654855Abstract: A device includes an ear occlude, an output transducer that is acoustically coupled to an ear canal of a wearer of the device, a voice microphone configured to generate a first electrical signal that is proportional to a voice-generated sound pressure at the microphone, and signal processing circuitry, electrically coupled to the output transducer and the microphone, including a compensator configured to generate, from the first electrical signal, a second electrical signal, and output the second electrical signal to the output transducer, wherein the compensator is tuned to cause GOE, a ratio of a sound pressure within the ear canal to a voice-generated sound pressure at a mouth reference point when the ear is occluded and electronically-aided to be approximately equal to GU, a ratio of the sound pressure within the ear canal to the voice-generated sound pressure at the mouth reference point when the ear is unoccluded.Type: GrantFiled: October 30, 2014Date of Patent: May 16, 2017Assignee: Bose CorporationInventors: Martin David Ring, Steven H.

Publication number: 20150063599Abstract: A headset includes a microphone for receiving a user's voice, a microphone for receiving ambient noise, a receiver for receiving a plurality of voice signals, a speaker for delivering sound to the user's ear and a processing device. The processing device is configured to identify a signal level of a first one of the plurality of voice signals and a second one of the plurality of voice signals, the signal level of the second voice signal being different than the signal level of the first voice signal. The processing device is also configured to measure the ambient noise level and adjust a gain applied to at least one of the first and second voice signals, taking into consideration the ambient noise level. The first and second voice signals are provided to the speaker.Type: ApplicationFiled: August 29, 2013Publication date: March 5, 2015Inventor: Martin David Ring

Patent number: 8620650Abstract: A system for combining signals includes a first microphone generating a first input signal having a first voice component and a first noise component, a second microphone generating a second input signal having a second voice component and a second noise component, a mixing circuit, and an adaptive filter. The mixing circuit applies a first gain having a value ? to the first input signal to produce a first scaled signal, applies a second gain having a value 1?? to the second input signal to produce a second scaled signal, and sums the first scaled signal and the second scaled signal to produce a summed signal. The adaptive filter computes an updated value of ? to minimize the energy of the summed signal based on the summed signal, the first input signal and the second input signal, and provides the updated value of ? to the mixing circuit.Type: GrantFiled: April 1, 2011Date of Patent: December 31, 2013Assignee: Bose CorporationInventors: Luke C.
