Abstract: Underwater communication using sensing fusion can include one or more electronic devices. The electronic device can include a housing defining an internal volume. The electronic device can include a speaker sealed to the housing and tuned for water use (e.g., to produce/detect audible and/or sonar frequency noise underwater). The speaker can include a diaphragm configured to resonate at one or more frequencies underwater. The electronic device can include a pressure compensator associated with the speaker to compensate for hydrostatic pressure acting on the diaphragm. The speaker can include a water permeable membrane to equalize pressure underwater within the speaker, while still maintaining a seal with the housing. The speaker can include multiple seals to prevent water ingress to the internal volume. The electronic device can include another speaker for land communication (e.g., to produce/detect audible noise on land).

Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may operate the speaker to generate audio output at one or more resonance frequencies of the speaker and/or the electronic device. This can allow the electronic device to generate particularly loud audio outputs while reducing the power consumption used to generate those audio outputs. In order, for example, to help ensure that the audio output is generated at the resonance frequencies, the electronic device can determine the resonance frequencies prior to generating the audio outputs. For example, the electronic device may determine resonance frequencies by obtaining one or more electrical characteristics of an electronic component while operating the speaker, and determine the resonance frequencies based on the obtained electrical characteristics.

Abstract: An electronic device includes a housing sidewall defining an opening and a display component, such as a display cover, disposed in the opening to form a gap between the housing sidewall and the display component. In at least one example, the cavity is defined by the sidewall and the display cover with the cavity in fluid communication with an external environment through the gap. In at least one example, an epoxy component at least partially defines the cavity and can be in direct contact with the housing sidewall.

Abstract: Aspects of the subject technology relate to electronic devices having speakers. An electronic device may operate the speaker at or near one or more resonance frequencies of the speaker and/or the electronic device. This can allow the electronic device to efficiently eject an occlusion when the speaker is occluded by a fluid or other debris. For example, the electronic device may determine a resonance frequency by obtaining one or more electrical characteristics of an electronic component while the speaker is occluded, determine the resonance frequency based on the obtained electrical characteristic(s), and operate the speaker at a frequency that is based on the resonance frequency to eject the occlusion.

Abstract: Aspects of the subject technology relate to providing audio alerts with electronic devices. An audio alert may be provided, in part, using power management operations that manage one or more both of the instantaneous power usage for providing the audio alert, and the long-term power usage for providing the audio alert.

Abstract: A transducer assembly comprising: an enclosure having an enclosure wall that defines a sound output port from an interior chamber of the enclosure; a sound radiating surface having a voice coil coupled thereto and dividing the interior chamber into a front volume chamber coupling a first side of the sound radiating surface to the sound output port and a back volume chamber coupled to a second side of the sound radiating surface; a magnet assembly having a magnet coupled to a yoke that defines in part the back volume chamber and an acoustic port from the back volume chamber; and a valve coupled to the acoustic port to close or open the acoustic port depending on whether the transducer assembly is in a distress mode or a non-distress mode.

Abstract: An electronic device can include a housing, an audio component, and a gasket. The housing can define a first internal volume and the audio component can define a second internal volume. The audio component can include membrane and a venting element having a fluid impermeable layer. The venting element can define a fluid path placing the first internal volume and the second internal volume in fluid communication. At least a portion of the fluid path can extend parallel to the fluid impermeable layer. The gasket can define a seal between the first internal volume and an ambient environment adjacent the housing.

Abstract: Aspects of the subject technology relate to determining a location of a device using sound that is output from the device. For example, an audio output from one or more speakers of an electronic device may be received at one or more microphones of another electronic device, and used by the other electronic device to determine the location of the electronic device.
