Patent ID: 8306500

Claim:
A mobile terminal comprising: a main body having a display module; a window on a case of the main body to cover at least a portion of the display module, the window including a recessed portion at an edge region formed along at least one side of the window; a touch sensor provided at the window to detect a touch input; a first piezoelectric substrate provided in the recessed portion of the window to generate a vibration in response to the touch input, the first piezoelectric substrate provided in a bar-like shape that corresponds to the recessed portion; a second piezoelectric substrate to cover the edge region of the window in an intersecting direction with the first piezoelectric substrate, the second piezoelectric substrate being provided at the case; and an elastic member disposed between the case and the first piezoelectric substrate to attenuate a vibration of the first piezoelectric substrate transferred to the case, wherein the first piezoelectric substrate is configured to substantially transfer the vibration to the window, and the second piezoelectric substrate is configured to transfer the vibration to both the window and the case.
