Abstract: Provided is a piezoelectric motor including: a stator which includes first and second faces, wherein a plurality of piezoelectric elements are arranged on the first face, and a plurality of protrusions are formed on the second face; a rotor which is rotated by motions of waves of the stator generated by the piezoelectric elements; and a driver device which applies driving voltages to the piezoelectric elements, wherein polarization directions of the plurality of piezoelectric elements are vertical to a rotary face of the rotor.

Abstract: A mobile terminal and digital broadcast receiving method thereof are disclosed, by which complicated procedures for digital broadcast reception in a mobile communication terminal can be simplified for user's convenience. The method according to an embodiment includes recognizing a number inputted via an input unit of the terminal in a standby mode, deciding whether a broadcast channel mapped by the inputted number exists in a memory, reading broadcast information for the broadcast channel mapped by the inputted number from digital multimedia service data and then displaying the broadcast information on a prescribed area of a display unit, and if a control signal for a digital broadcast reception is inputted while the broadcast information for the broadcast channel is displayed, entering a digital broadcast receiving mode of the broadcast channel.
