FEEDBACK CONTROL FOR CALIBRATION OF DISPLAY AS SOUND EMITTER

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.
