An in-ear electronic device comprising: an enclosure that defines an enclosed space surrounding a microphone and an acoustic opening to an ambient environment surrounding the enclosure; an acoustic pathway having a first end that opens to the acoustic opening and a second end that opens to the microphone; and a protective membrane positioned between the second end of the acoustic channel and the microphone.

Acoustic vent and protective membrane

An in-ear electronic device comprising: an enclosure that defines an enclosed space surrounding a driver and an acoustic vent to an ambient environment surrounding the enclosure; and an acoustic frame having an outer surface coupled to the enclosure and defining an acoustic channel between a back volume chamber of the driver to the acoustic vent.

A charging case for a pair of wireless earphones comprising: a housing having a peripheral wall that defines a shell; a frame insert coupled to the housing and extending into the shell, the frame insert having one or more insert walls that define first and second pockets sized and shaped to accept first and second wireless earphones, respectively, wherein the one or more insert walls cooperate with the housing primary wall to define a sealed chamber within the charging case; a lid coupled to the housing and operable between a closed position in which the lid covers the first and second pockets and an open position in which the first and second pockets are exposed; a speaker module disposed within the sealed chamber, the speaker module comprising an audio driver having a diaphragm that separates a front volume of the audio driver from a back volume of the audio driver and a speaker vent disposed within the back volume; one or more first openings formed through the peripheral wall and opening into the front volume, wherein the audio driver is positioned and aligned to emit sound into the front volume and through the one or more acoustic openings; and one or more second openings formed through the peripheral wall at a location spaced apart from the front volume, wherein at least one of the one or more second openings is an acoustic vent acoustically coupled to the back volume of the audio driver through the speaker vent ear tip.

Charging case for portable wireless listening device

A deformable ear tip comprising: an annular inner ear tip body having a sidewall extending between first and second opposing ends thereby defining a sound channel through the ear tip; an annular outer flange integrally formed with and surrounding the first end of the inner ear tip body and extending towards the inner ear tip second end forming an air gap between the annular inner ear tip body and the annular outer flange along a portion of a length of the ear tip, wherein the outer flange comprises a first material having a first durometer and is sized and shaped to be inserted into a human ear canal; and an inner flange integrally formed with the inner ear tip body and comprising a second material having a second durometer less than the first durometer, the inner flange body extending from a location along the inner ear tip body between the first and second ends towards an inner surface of the outer flange body.

Ear tip for portable wireless listening device

A processor is configured to perform headphone playback with a playback audio signal. The processor produces a feedback signal from an internal microphone, compresses the feedback signal according to a variable compressor setting, and determines a context of usage of the headphone, as being one of running or jogging, transportation, and critical listening. In response, the processor changes the variable compressor setting and drives the headphone speaker with the compressed feedback signal combined with the playback audio signal. Other aspects are also described and claimed.

Context aware compressor for headphone audio feedback path

A headphone earcup comprising: a frame defining an acoustic cavity that is acoustically coupled to a driver; an earcup cushion coupled to the frame and surrounding the acoustic cavity; and an adsorbent member acoustically coupled to the acoustic cavity to cause an acoustic enlargement of the acoustic cavity.

Headphone earcup with adsorptive material

An acoustic mesh comprising a first portion that is acoustically closed; and a second portion that surrounds the first portion and is acoustically open, wherein a surface area of the second portion is at least one percent a total surface area of the acoustic mesh.

Windscreen mesh

A method performed by an audio system that includes a headset. The method identifies a cushion that is coupled to a headset housing of the headset in which a speaker is integrated therein, produces a reference microphone signal from a reference microphone of the headset, selects an active noise cancellation (ANC) filter based on the identified cushion, filters the reference microphone signal with the ANC filter to produce an anti-noise signal, drives the speaker with the anti-noise signal, in response to driving the speaker, produces an error microphone signal from an error microphone of the headset, and performs an adaptive ANC function to adapt the ANC filter based on the reference microphone signal and the error microphone signal.

Method and system for adaptive audio filters for different headset cushions

A headphone earcup including a frame defining a cavity dimensioned to surround an ear of a user; a damping component coupled to the frame and encircling the cavity; a wrap component that covers the damping component and defines a continuous acoustic opening around the cavity to acoustically connect the cavity to the damping component; and a cosmetic component that covers the wrap component and the continuous acoustic opening.
