Cell phone vibrator motor behavior

Overview. We're often asked how to adjust the vibration amplitude or frequency of our various vibration motors.

In this article we'll look at how simple it is, why it can be useful, and how we can predict the behaviour of a motor using the driving voltage and Typical Performance Characteristics graph. This will be a more.

tion motor in mobile devices as a sound sensor, almost like a microphone. learning. While these findings are not fundamentally sur- prising (given that any vibrating object should respond to air vibrations), the fidelity to which this is possible has been somewhat to a phone's vibra-motor may now be able to eavesdrop.
