Abstract
A portable electronic device comprising an external surface of a user interface, a piezoelectric transducer coupled to the external surface, and a controller. The piezoelectric transducer generates an electrical output originating at the piezoelectric transducer in response to mechanical actuation applied at the external surface. The controller performs an electronic function of the portable electronic device in response to the piezoelectric transducer generating the electrical output.
