Abstract
A mobile terminal as broadly described herein may comprise a terminal body including a display module, a touch sensor disposed to overlap the display module and configured to be touch sensitive, haptic modules mounted at the body, and a controller configured to feed a current to at least one of the haptic modules when the touch sensor senses a touch input. Each haptic module may include a chamber covered by a flexible membrane and an actuating module accommodated in the chamber and configured to press the flexible membrane based on an energy conversion of the current such that the flexible membrane is expanded.
