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.
