Implementations of the subject technology provide for a microphone in the front volume of a speaker. The speaker and the microphone may be provided in a single speaker assembly. The microphone may be implemented as an error microphone or a feedback microphone. The microphone may be mounted to a speaker frame of the speaker, with a sound-sensitive element of the microphone in the front volume of the speaker on a first side of the speaker frame, and with conductive contacts for the microphone disposed on an opposing second side of the speaker frame.

Speaker and microphone for acoustic devices

A portable electronic device comprising: an enclosure having an enclosure wall that forms an interior chamber containing a transducer and a valve operable to open or close a vent to the interior chamber; and a particle removal mechanism coupled to the valve that is operable to drive particles away from the valve upon application of a current.

Ultrasonic particle reduction system for an acoustic micro-valve

An in-ear electronic device comprising: an enclosure having an enclosure wall that defines an interior chamber surrounding a transducer and an opening from the interior chamber to an ambient environment surrounding the enclosure; and an acoustic valve comprising a driven member coupled to a driving member having a lever and a shape memory alloy operable to cause the driven member to open and close the opening upon application of a current.

Shape memory alloy valve for an electronic device

A low-profile earbud is disclosed that sits securely within an ear of a user. The earbud includes a protruding portion that passes through a channel defined by the tragus and anti-tragus of the ear. In some embodiments, the protruding portion can take the form of a cable configured to supply power and transfer data to the earbud. In some embodiments, the protruding portion can provide additional space for electrical components and sensors supporting the earbud.

In-ear headphone

A portable electronic device comprising: an enclosure having an enclosure wall that defines a first chamber, a second chamber and an acoustic opening from the first chamber or the second chamber; and an electroosmotic flow valve operable to open and close the acoustic opening.

Electroosmotic flow valve for an electronic device

A portable electronic device comprising: an enclosure having an enclosure wall that forms an interior chamber and a sound output port to an ambient environment; a transducer positioned within the interior chamber and dividing the interior chamber into a front volume chamber coupling a first side of the transducer to the sound output port and a back volume chamber coupled to a second side of the transducer; and an electromechanical valve comprising a number of flaps operable to open and close a vent to the interior chamber, the front volume chamber or the back volume chamber.

Dynamic valve for an electronic device

A portable electronic device comprising: an enclosure having an enclosure wall that forms an interior chamber and an opening to an environment surrounding the enclosure wall; and a valve comprising a number of sliding actuators operable to open and close the opening to the environment surrounding the enclosure wall.

A user content audio signal is converted into sound that is delivered into an ear canal of a wearer of an in-ear speaker, while the in-ear speaker is sealing off the ear canal against ambient sound leakage. An acoustic or venting valve in the in-ear speaker is automatically signaled to open, so that sound inside the ear canal is allowed to travel out into an ambient environment through the valve, while activating conversion of an ambient content audio signal into sound for delivery into the ear canal. Both user content and ambient content are heard by the wearer. The ambient content audio signal is digitally processed so that certain frequency components have been gain adjusted, based on an equalization profile, so as to compensate for some of the insertion loss that is due to the in-ear speaker blocking the ear canal. Other embodiments are also described and claimed.

In-ear speaker hybrid audio transparency system

An earbud design is disclosed that is configured to sit securely within an ear of a user. The earbud can be secured within the ear by an anchoring feature formed from an elastomeric material. The anchoring feature has a size and shape in accordance with an interior geometry of an ear of a user. Because the anchoring feature positions the earbud with respect to the ear, geometries of the earbud can be focused upon audio performance and/or device aesthetics. In some embodiments, the earbud housing can have a linear design which allows an audio driver within the earbud housing to be positioned close to an opening defined by the earbud housing. In this way, acoustic degradation associated with a long audio path from the audio driver to the opening can be avoided.

Earbud stability anchor feature

A portable acoustic device comprising: a device housing that defines an internal cavity, the device housing comprising a speaker housing portion and a stem portion extending away from the speaker housing portion; a first acoustic port formed through a wall of the speaker housing; an audio driver disposed within the speaker housing portion and aligned to emit sound through the acoustic first port; a battery disposed within the speaker housing portion and positioned an opposite side of the audio driver than the acoustic port; an antenna disposed in the stem; a user input region disposed along the stem; and a system in a chip disposed in the stem, the system in a chip comprising: a processor that controls operation of the portable wireless acoustic device, charging circuitry, an accelerometer, a wireless communication controller, support components for the antenna and support components for the user input region.

Wireless listening device

A method performed by an in-ear headphone that includes a speaker and an internal microphone. The method receives a microphone signal from the internal microphone that indicates a current sound pressure level (SPL) in an ear canal of a user. The current SPL is a result of a control leak from the in-ear headphone into an ambient environment that reduces a SPL in the ear canal between 2 dB and 25 dB at a frequency within a frequency range than if otherwise not present. The method determines an active noise cancellation (ANC) filter based on the microphone signal and generates an anti-noise signal using the ANC filter. The method drives the speaker using the anti-noise signal to reduce the current SPL in the ear canal of the user as much as 25 dB at a frequency within the frequency range.
