Piezo vibration motor

PURPOSE: A piezo vibrating motor is provided to vibrate a weight upward and downward by using a piezo in which the center portion is concavely or convexly bent according to intensity and direction of a voltage, thereby multiplying motor vibration amount. CONSTITUTION: An elastic member(9) has a right side elastic piece(7) in regard to a fixed vertical member(3). The center portion of a plate(13) is concavely or convexly bent by a piezo(11). The center portion of piezo is concavely or convexly bent and the piezo generates up-down vibration. A weight(15) vibrates upward and downward according to the plate. The opened lower end side of a case(17) is closed through a bracket(1). The case covers the elastic member, the plate, the piezo, and the weight.
