Abstract
A computer-implemented method includes generating a first signal; generating vibrations in a mobile device based on the first signal; and sensing, using a microphone associated with the mobile device, sound generated by the vibrations. The method further includes generating an output based on the sound sensed by the microphone, measuring a level of the sound based on the output, and detecting a resonant frequency of the mobile device based on the level of the sound.
