Patent number: 11729542Abstract: An ear-mountable listening device includes an acoustic package and an electronics package. The acoustic package is configured to emit audio in response to an audio signal. The acoustic package includes a first set of magnets arranged annularly about a central axis of the ear-mountable listening device. The electronics package is electrically coupled to the acoustic package when the ear-mountable listening device is worn to provide the audio signal to the acoustic package. The electronics package includes a second set of magnets arranged annularly about the central axis proximate to a proximal end of the electronics package to removably affix the electronics package to the acoustic package via magnetic forces between the first set of magnets and the second set of magnets.Type: GrantFiled: June 11, 2021Date of Patent: August 15, 2023Assignee: Iyo Inc.Inventors: Simon Carlile, Jason Rugolo

Patent number: 11722809Abstract: A method performed by an in-ear headphone. Coupled to the in-ear headphone is a first ear tip that is inserted into an ear canal of a user. The method obtains an audio signal from an audio source device paired with the in-ear headphone and uses the signal to drive a speaker of the headphone to output a sound into the ear canal. The method obtains a microphone signal that is responsive to the outputted sound. The method notifies the user to replace the first ear tip with a second ear tip in response to a parameter associated with the microphone signal being less than a threshold.Type: GrantFiled: August 29, 2022Date of Patent: August 8, 2023Assignee: Apple Inc.Inventors: Esge B. Andersen, Andrew E. Greenwood, Tom-Davy W. Saux, Baptiste P. Paquier, Hanchi Chen, Raghavendra S. Prabhu

Patent number: 11716567Abstract: A wearable device can provide an audio module that is operable to provide audio output from a distance away from the ears of the user. For example, the wearable device can be worn on clothing of the user and direct audio waves to the ears of the user. Such audio waves can be focused by a parametric array of speakers that limit audibility by others. Thus, the privacy of the audio directed to the user can be maintained without requiring the user to wear audio headsets on, over, or in the ears of the user. The wearable device can further include microphones and/or connections to other devices that facilitate calibration of the audio module of the wearable device. The wearable device can further include user sensors that are configured to detect, measure, and/or track one or more properties of the user.Type: GrantFiled: July 22, 2021Date of Patent: August 1, 2023Assignee: APPLE INC.Inventors: Daniel A. Podhajny, Joshua A. Hoover, Nicholas R. Trincia, Yue Chen, Seul Bi Kim, Chad J. Miller, Kristen L. Cretella, Yi Zou, William Leith

Patent number: 11710473Abstract: Earpieces and methods for acute sound detection and reproduction are provided. A method can include measuring an external ambient sound level (xASL), monitoring a change in the xASL for detecting an acute sound, estimating a proximity of the acute sound, and upon detecting the acute sound and its proximity, reproducing the acute sound within an ear canal, where the ear canal is at least partially occluded by an earpiece. Other embodiments are disclosed.Type: GrantFiled: February 3, 2022Date of Patent: July 25, 2023Assignee: Staton Techiya LLCInventors: Steven Wayne Goldstein, John Usher, Marc Andre Boillot

Patent number: 11706555Abstract: A method performed by a programmed processor of an in-ear headphone that is to be worn by a user. The method obtains, over a wireless communication link and via a first wireless connection that uses an accessory profile, a first request, from an audio source device, to start a measurement process. In response to obtaining the request, the method 1) establishes, over the link, a second wireless connection that uses an audio distribution profile between the headphone and the source device, 2) obtains, via the second wireless connection, an audio signal for driving a speaker of the headphone to output sound, 3) responsive to the outputted sound, determining a fit parameter, and 4) transmitting the fit parameter to the source device via the first wireless connection.Type: GrantFiled: July 1, 2020Date of Patent: July 18, 2023Assignee: Apple Inc.Inventors: Kang Sun, Sriram Hariharan, Robert D. Watson, Sarang S. Ranade, Kevin Durfee

Patent number: 11695381Abstract: A system comprising audio processing circuitry is provided. The audio processing circuitry is operable to receive audio signals. The audio processing circuitry is operable to process the audio signals to detect strength of a chat component of the audio signals and strength of a game component of the audio signals. The audio processing circuitry is operable to automatically control a volume setting based on one or both of: the detected strength of the chat component, and the detected strength of the game component. The combined-game-and-chat audio signals may comprise a left channel signal and a right channel signal. The processing of the combined-game-and-chat audio signals may comprise measuring strength of a vocal-band signal component that is common to the left channel signal and the right channel signal.Type: GrantFiled: June 9, 2021Date of Patent: July 4, 2023Assignee: Voyetra Turtle Beach, Inc.Inventors: Richard Kulavik, Shobha Devi Kuruba Buchannagari, Carmine Bonanno

Patent number: 11689841Abstract: An earbud includes an earbud speaker, a microphone array including a plurality of microphones, an orientation sensing subsystem, and a beamforming subsystem. The orientation sensing subsystem is configured to output an orientation signal indicating an orientation of the earbud. The beamforming subsystem is configured to output a beamformed signal. The beamformed signal is based at least on the orientation signal and a plurality of microphone signals from the plurality of microphones in the microphone array. The beamformed signal spatially selectively filters the plurality of microphone signals.Type: GrantFiled: September 29, 2021Date of Patent: June 27, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Amir Zyskind, Eliza C.
