    Abstract: A microphone device includes a microphone array configured to capture one or more audio objects associated with a three-dimensional sound field. The microphone array includes a first cluster and a second cluster. The first cluster includes a first set of two or more microphone elements and the second cluster includes a second set of two or more microphone elements. The microphone device also includes a processor coupled to the microphone array. The processor is configured to receive directionality information associated with a sound source. The processor is also configured to select a first microphone element configuration for the first cluster based on a condition, the directionality information, or both. Each microphone element of the first set of two or more microphone elements is deactivated in response to selection of the first microphone element configuration.

    Abstract: Aspects of the disclosure relate to using a display as a sound emitter and may relate to an electronic device including a display and for sound leak cancellation. A vibration sensor such as an accelerometer is physically coupled to the display and senses the display vibration to provide a signal representing actual acoustic output from the display. The electronic device includes a first actuator physically coupled to the display and configured to cause vibration of the display in response to a first audio signal. The electronic device further includes the vibration sensor configured to output a vibration sensor signal proportional to the vibration of the display. The electronic device further includes a second actuator physically coupled to a portion of the electronic device different from where the first actuator is physically coupled to the display and configured to cause vibration of the portion in response to a second audio signal.

    Abstract: Aspects of the disclosure relate to using a display as a sound emitter and may relate to an electronic device including a display. In particular a vibration sensor such as an accelerometer is physically coupled to the display and senses display vibration to provide a high accuracy feedback loop with respect to representing actual audio output from the display. The electronic device includes an actuator physically coupled to the display and configured to cause vibration of the display in response to an audio signal. The electronic device further includes a vibration sensor physically coupled to the display and configured to output a vibration sensor signal proportional to the vibration of the display due to the actuator. The electronic device further includes a processor operably coupled to the vibration sensor. The processor is configured to adjust the audio signal based on the vibration sensor signal from the vibration sensor.
