Improved acoustic devices include water-resistant venting across various surfaces inside acoustic devices such as speakers and microphones. Surfaces such as an acoustic diaphragm, a cover for a resonant chamber, and a cover for an external port of an acoustic transducer may include design features that create or enhance gas-permeable and water impermeable attributes. Such design features include, for example, a series of apertures in the vented surface.

Integrated barometric vent

A multi-radius spherical microphone that includes an inner body defining an inner sphere having an inner radius from a center; a plurality of inner microphones coupled to the inner spherical body and defining an array of inner microphones; an outer body defining an dodecahedron, wherein the inner body and the outer body are concentric about the center; and a plurality of outer microphones coupled to the outer body at respective vertices of the dodecahedron and defining an array of outer microphones, wherein each of the plurality of outer microphones is positioned radially equidistant from the center.

Aspects of the subject technology relate to electronic devices having microphones. An electronic device may include a microphone and a resonator for the microphone. The resonator may be formed in a device structure that is spatially separated from the microphone. The resonator may be formed in an interior wall of a housing of the electronic device, or in a support structure within an enclosure of the electronic device. A resonator and/or one or more damping features, may reduce a resonance effect, on the microphone, of a resonant cavity within the enclosure of the electronic device and adjacent the microphone.

Acoustic resonators for microphones

An electronic device may include an enclosure, an antenna within the enclosure and configured to transmit a wireless signal to a remote electronic device to allow a location of the electronic device to be determined, an audio output system configured to produce an audible output, and a processing system within the enclosure and configured to determine, based on an electrical response induced in the antenna, whether the audio output system fails an audio output performance criteria when provided with an audio signal.

Electronic device with audio system testing

Aspects of the subject technology relate to electronic devices having speakers and airflow sensors for the speakers. In one or more implementations, the airflow sensor may be formed, in part, by a mesh structure that spans a port in a housing of the electronic device. In one or more implementations, the airflow sensor may be formed, in part, by an exposed portion of a conductive trace of the speaker.

Airflow sensors for speakers

The present disclosure generally relates techniques for audio-assisted enrollment of biometric features. In some embodiments, methods and devices for assisting users with enrollment of biometric features, using spatial audio cues, are described.

Audio assisted enrollment

An electronic device has a housing that forms an exterior surface of the electronic device. An array of actuators is coupled to the housing and is operable to move the housing in order to produce sound waves and/or haptic output via the exterior surface. In this way, less space is consumed by acoustic and haptic devices as compared to similar conventional devices, thereby allowing for thinner electronic devices and/or room for other components within the housing. The actuators may be operable to move different regions of the housing to produce sound waves and/or haptic output within different frequency ranges.

Electronic device with actuators for producing haptic and audio output along a device housing

A wirelessly locatable tag may include a first housing member defining a first exterior surface of the wirelessly locatable tag and an interior surface opposite the first exterior surface. The wirelessly locatable tag may further include a second housing member defining a second exterior surface of the wirelessly locatable tag a first antenna configured transmit the wireless signal using a first wireless protocol, a second antenna configured to communicate using a second wireless protocol different than the first wireless protocol, and an audio system. The audio system may include a magnet assembly configured to produce a magnetic field and a coil positioned within the magnetic field and coupled to the interior surface of the first housing member, the coil configured to interact with the magnetic field to impart a force on the first housing member, thereby moving a portion of the first housing member to produce an audible output.

Audio output system for a wirelessly locatable tag

A system for securing a user device to a body includes a magnet and an attraction plate. One of the magnet or the attraction plate is mechanically coupled to the body, and the other of the magnet or the attraction plate is mechanically coupled to the user device. The magnet is selectively activated to hold the attraction plate and, thereby, secure the user device to the body.

System for holding devices

Aspects of the subject technology relate to electronic devices having sensors such as pressure sensors. A pressure sensor may be integrated into an audio component of an electronic device such that the pressure sensor is fluidly coupled to an environment external to a device housing via at least a portion of an internal cavity of the audio component housing. The audio component housing may include an opening. The pressure sensor may be mounted adjacent to or within the opening. The opening may be sealed to prevent passage of gas or liquid through the opening. The pressure sensor may be integrally formed with an inner wall of the audio component housing. The audio component may be a speaker or a microphone.

Speaker integrated environmental sensors

A piezoelectric actuator including an upper piezoelectric bimorph beam having a first upper piezoelectric layer, a second upper piezoelectric layer and at least three upper electrode layers extending between a first end and a second end of the upper piezoelectric bimorph beam; a lower piezoelectric bimorph beam having a first lower piezoelectric layer, a second lower piezoelectric layer and at least three lower electrode layers extending between a first end and a second end of the lower piezoelectric bimorph beam, and wherein the first end of the lower piezoelectric bimorph beam is coupled to the first end of the upper piezoelectric bimorph beam by a first joint, and the second end of the lower piezoelectric bimorph beam is coupled to second end of the upper piezoelectric bimorph beam; and a base member coupled to a center region of the lower piezoelectric bimorph beam.

Composite piezoelectric actuator

An electronic device has an acoustic transducer with an acoustic diaphragm. The diaphragm has opposed first and second major surfaces. A front volume is positioned adjacent the first major surface. A back volume is positioned adjacent the second major surface. An elongated channel defines a barometric vent and extends from a first end fluidly coupled with the front volume to a second end fluidly coupled with the back volume, fluidly coupling the front volume with the back volume. The elongated channel may have a high aspect ratio (L/D), providing the vent with a substantial air mass. The elongated channel may be segmented to define a higher-order filter. For example, a segmented channel can have a cascade of repeating acoustic-mass and acoustic-compliance units, providing the barometric vent with additional degrees-of-freedom for tuning.
