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: An audio/video (A/V) hub that coordinates playback of audio content is described. In particular, the A/V hub may calculate current time offsets between clocks in electronic devices and a clock in the A/V hub based on differences between receive times when frames are received from electronic devices and expected transmit times of the frames. For example, the expected transmit times may be based on coordination of clocks in the electronic devices and a clock in the A/V hub at a previous time and a predefined transmit schedule of the frames. 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 current time offsets.

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 electronic device that performs automatic room filling 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 number of individuals in the environment. Then, based at least in part on the determined number of individuals, the electronic device may calculate an acoustic radiation pattern. For example, a width of a beam in the acoustic radiation pattern may be narrower when there is one individual in the environment, and the width of the beam may be wider when there is more than one individual in the environment. Next, the electronic device may provide audio content and second information specifying the acoustic radiation pattern for the second electronic device.

Abstract: An electronic device that dynamically adapts sound based at least in part on spatial information determined from ambient or background sound is described. Based at least in part on sound measurements corresponding to ambient noise in an environment, which may include a second electronic device, the electronic device may determine a characteristic of the environment. For example, the characteristic may include: a size of the environment, an acoustic mode of the environment and/or a reverberation time of the environment, which is associated with at least a frequency. Then, based at least in part on the determined characteristics, the electronic device may calculate an acoustic radiation pattern. Next, the electronic device may provide audio content and second information specifying the acoustic radiation pattern for the second electronic device.

Abstract: An electronic device that performs dynamic cross-talk cancellation is described. The electronic device may acquire information about an environment, which may include a second electronic device. Based at least in part on the information, the electronic device may determine locations of different individuals in the environment. Then, based at least in part on the locations, the electronic device may calculate an acoustic radiation pattern of a second electronic device. The acoustic radiation pattern may include a beam having a principal direction approximately directed towards the location of one individual, and an exclusion zone in which an intensity of output sound is reduced below a threshold value and that includes the location of another individual. Next, the electronic device may provide audio content and second information specifying the acoustic radiation pattern for the second electronic device.

Abstract: An electronic device that dynamically adapts sound based at least in part on content and context is described. The electronic device may acquire information about an environment, which may include the second electronic device. Based at least in part on the information, the electronic device may determine a context associated with the environment (such as a number of individuals in the environment, a type of lighting in the environment, a time or a timestamp, a location, etc.). Then, based at least in part on the determined context and a characteristic of audio content (such as a type of music), the electronic device may calculate an acoustic radiation pattern. Next, the electronic device may provide the audio content and second information specifying the acoustic radiation pattern for the second electronic device.

Abstract: An electronic device that dynamically adapts sound based at least in part on environmental characterization 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 change in a characteristic of the environment. For example, the change in the characteristic may include a change in a reverberation time of the environment, which is associated with at least a frequency. Then, based at least in part on the determined change in the characteristic, the electronic device may calculate an acoustic radiation pattern, where the calculated acoustic radiation pattern reduces an effect of the change in the characteristic on sound in the environment. Next, the electronic device may provide audio content and second information specifying the acoustic radiation pattern for the second electronic device.

Abstract: In response to receiving user-interface activity information from a portable electronic device that specifies user selection of a content source, an audio/video (A/V) hub provides a request for high-definition multimedia-interface (HDMI) content to the content source based on the user selection. When the A/V hub receives the HDMI content from the content source, the A/V hub provide the HDMI content and 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 while other HDMI content from another content source is displayed on the display.
