Abstract: 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.

Abstract: 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.

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 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.
