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.

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: A presence of a person within a camera field of view of an electronic device is determined by digitally processing images captured by a camera. A position of a body member of the person with respect to the electronic device is also computed by digitally processing the camera captured images. A crosstalk cancellation (XTC) signal is adjusted based on the computed position of the body member. Adjusting the XTC signal includes adjusting a first predetermined model location, which includes a location at which a user should be in order to achieve a desired virtual acoustics effect. Processing program audio based on the adjusted XTC signal, to generate audio signals that drive speakers. Other aspects are also described and claimed.

Abstract: A portable electronic device is described in this disclosure. The portable electronic device can take many forms including for example a smart watch, a smart phone, or a tablet computing device. The portable electronic device can include a device housing component; and a display assembly coupled to the device housing component. The display assembly includes a protective cover that shields a display component from damage. The portable electronic device also includes an actuator configured to apply a vibratory input to the display assembly. In some embodiments, the actuator contacts both the device housing component and the protective cover of the display assembly. In some embodiments, the actuator is affixed only to an interior-facing surface of the display component.

Abstract: An electronic device can include one or more actuators. The actuator or actuators may be operably connected to a feedback surface. Movement is produced in at least one actuator that causes an audio output. The movement in the actuator(s) by itself may produce the desired audio output. The movement in the actuator(s) can produce a force in at least one direction that produces movement in the feedback surface, and the movement in the feedback surface produces audio output. The movement in the actuator may also provide a haptic output to a user.

Abstract: The described embodiments relate to an electronic assembly that includes multiple varied electrical components. In some embodiments, the electronic assembly can include electrical components susceptible to electromagnetic interference (EMI). In one particular embodiment, an antenna can be positioned along an exterior surface of an enclosure of the electronic assembly and another electrical component can be disposed within the enclosure. When the other electrical component is a speaker component, a port or opening for emitting audio output can be protected from EMI by surrounding the port with a conductive gasket that includes a closed cell foam substrate wrapped in an electrically conductive fabric. In some embodiments, the closed cell foam substrate defines a number of perforations that are plated with an electrically conductive material.

Abstract: An electronic device having several speaker modules that are acoustically in-phase and mechanically out-of-phase is disclosed. Embodiments include a pair of speaker modules mounted at respective ends of a lateral link, and the lateral link may be supported relative to a housing of the electronic device. The speaker modules may receive a same audio signal, and the audio signal may drive a first voicecoil in a first direction and a second voicecoil in a second direction. Accordingly, the speaker modules may be driven in mechanically different directions by the same audio signal, such that reactive forces cancel and/or mechanical energy is dissipate in the lateral link between the speaker modules. Other embodiments are also described and claimed.

Abstract: A first electronic device includes a first coil that is operative in at least two modes. In a first mode, the first coil may be utilized to moves a membrane to produce one or more sound waves, register movement of a membrane to detect one or more sound waves, or generates one or more haptic outputs. In the second mode, the first coil may be used to inductively transmit power to and/or inductively receive power from a second coil included in a second electronic device. In various cases, the second coil may be a dedicated inductive power transmission coil. In other cases, the second coil may be capable of multimode operation similar to the first coil.
