Abstract
There is disclosed a mobile terminal comprising: a display module; a first piezoelectric layer provided on a rear surface of the display module and configured to vibrate the display module by forming a first frequency in an audible range; and a second piezoelectric layer provided on the rear surface of the display module and configured to sense the pressure transmitted from the display module and provide a haptic feedback at a second frequency, wherein the second piezoelectric layer is thicker than the first piezoelectric layer in a front-to-back direction and fixedly coupled to the first piezoelectric layer.
