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.

Abstract: A multi-channel sound (MCS) system features intelligent calibration (e.g., of acoustic echo cancelation (AEC)) for use in dynamic acoustic environments. A sensor subsystem is utilized to detect and identify changes in the acoustic environment and determine a “scene” corresponding to the resulting acoustic characteristics for that environment. This detected scene is compared to predetermined scenes corresponding to the acoustic environment. Each predetermined scene has a corresponding pre-tuned filter configuration for optimal AEC performance. Based on the results of the comparison, the pre-tuned filter configuration corresponding to the predetermined scene that most closely matches the detected scene is utilized by the AEC subsystem of the multi-channel sound system.

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.
