Active Noise Reduction Earbud

View page
US Patent:
20220417646, Dec 29, 2022
Filed:
Jun 29, 2021
Appl. No.:
17/362625
Inventors:
- Framingham MA, US
Lei Cheng - Wellesley MA, US
Ole Nielsen - Cambridge, GB
Emery Ku - Sudbury MA, US
Cedrik Bacon - Ashland MA, US
International Classification:
H04R 1/10
G10K 11/178
Abstract:
An active noise reduction earbud and method. The earbud includes a housing comprising an outlet portion that defines a sound outlet, wherein the outlet portion is configured to be located in or proximate the external auditory meatus of a user's ear, a first feedforward microphone configured to develop a first input signal, and a first sound inlet opening in the housing and configured to conduct external sound to be sensed by the first feedforward microphone, wherein the first sound inlet opening is proximate the outlet portion.

Catalyst Support Materials For Fuel Cells

View page
US Patent:
20220263098, Aug 18, 2022
Filed:
May 2, 2022
Appl. No.:
17/734558
Inventors:
- Stuttgart, DE
Jonathan MAILOA - Cambridge MA, US
Mordechai KORNBLUTH - Brighton MA, US
Lei CHENG - Sunnyvale CA, US
Georgy SAMSONIDZE - San Francisco CA, US
Boris KOZINSKY - Waban MA, US
Nathan CRAIG - Santa Clara CA, US
International Classification:
H01M 4/90
H01M 4/88
H01M 4/92
Abstract:
A catalyst support material for a proton exchange membrane fuel cell (PEMFC). The catalyst support material includes a metal material of an at least partially oxidized form of TiNbOreactive with HO, HF and/or SOto form reaction products in which the metal material of the at least partially oxidized form of TiNbOaccounts for a stable molar percentage of the reaction products.

Active Noise Reduction Earbud

View page
US Patent:
20230099287, Mar 30, 2023
Filed:
Dec 2, 2022
Appl. No.:
18/073699
Inventors:
- Framingham MA, US
Lei Cheng - Wellesley MA, US
Ole Nielsen - Cambridge, GB
Emery Ku - Sudbury MA, US
Cedrik Bacon - Ashland MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
H04R 1/10
G10K 11/178
Abstract:
An active noise reduction earbud includes a housing and a first feedforward microphone disposed in the housing. A first sound inlet opening extends through the housing and is configured to conduct external sound to the first feedforward microphone. The first sound inlet opening is configured to sit within a concha cavum of a user's ear and faces toward an auricle of the user's ear when the earbud is worn.

Hearing Assistance Devices And Methods Of Generating A Resonance Within A Hearing Assistance Device

View page
US Patent:
20230076171, Mar 9, 2023
Filed:
Sep 3, 2021
Appl. No.:
17/446896
Inventors:
- Framingham MA, US
Shaun Ente - Brighton MA, US
Lei Cheng - Wellesley MA, US
Assignee:
Bose Corporation - Framingham MA
International Classification:
H04R 25/00
Abstract:
The present disclosure provides hearing assistance devices and methods of generating a resonance within hearing assistance devices that use moving coil drivers, e.g., electro-dynamic coil drivers. As small moving coil drivers are typically inefficient within the voice band of frequencies, e.g., above 1 kHz, the hearing assistance devices described herein utilize the resonance of a mass within the hearing assistance device and a compliance of air within the housing of the hearing assistance device or within portions of the acoustic driver housing to aid in amplification of select frequencies within the voice band of human speech, e.g., between 2.5 kHz and 6 kHz. By using the assistance of the resonance created, the moving coil driver utilized does not need to operate as efficiently within the range of resonance frequencies.

Wearable Active Noise Reduction (Anr) Device Having Low Frequency Feedback Loop Modulation

View page
US Patent:
20210280162, Sep 9, 2021
Filed:
Mar 6, 2020
Appl. No.:
16/811148
Inventors:
- Framingham MA, US
David J. Warkentin - Boston MA, US
Lei Cheng - Wellesley MA, US
Brandon Lee Olmos - Cambridge MA, US
Michael P. O'Connell - Northborough MA, US
International Classification:
G10K 11/178
H04R 1/10
H04R 3/00
Abstract:
Various aspects include a wearable audio device having active noise reduction (ANR), where the ANR device includes: a feedback microphone; an electroacoustic transducer; and a feedback compensator configured to output a noise reduction signal to the electroacoustic transducer in response to a feedback signal from the feedback microphone, wherein the feedback compensator includes a tunable filter that modulates a loop gain in response to an adverse low frequency event being detected in the noise reduction signal outputted from the tunable filter, wherein the tunable filter is configured to maintain a substantially similar loop gain shape near a low frequency cross-over as the low frequency cross-over changes during loop gain modulation.
