Abstract: An audio/video (A/V) hub that calculates an estimated location is described. In particular, the A/V hub may calculate an estimated location of a listener relative to electronic devices (such as electronic devices that include speakers) in an environment that includes the A/V hub and the electronic devices based on: communication with another electronic device; sound measurements in the environment; and/or time-of-flight measurements. Then, the A/V hub may transmit, to the electronic devices, one or more frames that include audio content and playback timing information, which may specify playback times when the electronic devices are to playback the audio content based on the estimated location. Moreover, the playback times of the electronic devices may have a temporal relationship so that the playback of the audio content by the electronic devices is coordinated.

Abstract: A portable electronic device with a touch-sensitive display (such as a cellular telephone) provides a wireless remote control for an entertainment device (such as a consumer-electronic device). Based on device-state information that specifies a current state of the entertainment device (which is received from an audio/video (A/V) hub that communicates with the entertainment device) and one or more related states of the entertainment device, the portable electronic device may generate a user interface that includes one or more virtual command icons. Note that the one or more related states are related to the current state in a state diagram by corresponding operations that transition the entertainment device from the current state to the one or more related states. Then, the portable electronic displays the user interface on the touch-sensitive display. In this way, the portable electronic device dynamically adapts the user interface.

Abstract: An electronic device that performs active room shaping and/or noise control is described. The electronic device may acquire information about an environment, which may include a second electronic device and a third electronic device. Based at least in part on audio content, locations of a second electronic device and a third electronic device and a location of a boundary of the environment, one or more of which may be specified by the information, the electronic device may calculate acoustic radiation patterns of the second electronic device and the third electronic device, where the acoustic radiation patterns selectively modify a reverberation characteristic of the environment. Then, the electronic device may provide the audio content and second information specifying the acoustic radiation patterns for the second electronic device and the third electronic device.

Abstract: An electronic device that performs volume normalization is described. Based at least in part on information about an environment, which may include a second electronic device, the electronic device may determine a location of at least an individual relative to a location of the second electronic device. Then, based at least in part on the determined location, the electronic device may calculate a volume setting of a speaker in the second electronic device. For example, the volume setting may increase as a distance between the location of the individual and the location of the second electronic device increases. Alternatively or additionally, the volume setting may be based at least in part on a size of a display device in the environment. Next, the electronic device may provide audio content and second information specifying the volume setting for the second electronic device.

Abstract: An electronic device that provides dynamic equalization in a directional speaker array is described. Based at least in part on audio content and an acoustic radiation pattern associated with a second electronic device, the electronic device may determine drive signals for a set of drivers. Then, the electronic device may adjust the drive signals for at least a subset of the set of drivers based at least in part on a distortion margin in at least the subset of the drivers, where the distortion margin is based at least in part on the drive signals, a distortion threshold of at least the subset of the drivers and a volume setting. Next, based at least in part on the adjusted drive signals, the electronic device may output, using the set of drivers, the sound corresponding to the audio content.

Abstract: A computer system may receive, from an acoustic transducer and/or a portable electronic device, information specifying one or more desired operations that are to be performed. This information may include natural language describing the one or more desired operations. In response, the computer system may transform the natural language into the one or more desired operations, and may identify a subset of the electronic devices based on the one or more desired operations and a predetermined supervised learning model that relates desired operations and the electronic devices. Next, the computer system may determine a set of commands based on the one or more desired operations and the subset of the electronic devices, and the computer system may provide the set of commands to the identified subset of the electronic devices, which may perform the one or more desired operations.

Abstract: A loudspeaker diaphragm (12) comprising a woven fibre body supports damping material (25), for example PVA polymer, on a rearward-facing surface (24). The woven fibre body may be formed of lengths (14) non-metallic fibre material (for example glass fibre) coating with a thin metal coating (32). The mass of the layer of damping material (25) may be less than the mass of the woven fibre body. An attractive sparkly looking loudspeaker diaphragm (12) may thus be provided which damps undesirable vibration whilst providing a flatter frequency-response curve (50).

Abstract: An audio/video (A/V) hub determines display instructions specifying information to be displayed on a display in an A/V display device that includes icons associated with content sources. Then, the A/V hub provides the display instructions to the A/V display device for display on the display. In response to receiving a user selection of a content source based on activation of a single command feature in a portable electronic device that is associated with the content source, the A/V hub provides a request for high-definition multimedia-interface (HDMI) content to the content source. When the A/V hub receives the HDMI content from the content source, the A/V hub provide the HDMI content and second display instructions to an A/V display device as frames with the HDMI content are received from the content source, so that the HDMI content is displayed in a tiled window on the display in the A/V display device.
