Abstract: PURPOSE:To generate great output and save a space by providing the external surface of a square-drum-like base body, with a plurality of respective piezoelectric elements, to arrange driving elements confronted with a square drum internal-wall surface and to apply ultrasonic wave zone electric-signal to the respective groups of the piezoelectric elements, and by generating the complex resonance of an expanding or shrinking mode in the longitudinal direction and a bending mode for opening or closing a drum port, on the base body. CONSTITUTION:When electric signal is applied to the sides of first group piezoelectric elements 2a, 2b, 3a, 3b, then a base body 1 is expanded in the longitudinal direction and at the same time, piezoelectric element surfaces with voltage applied to are opened to external sides in the vertical direction, and so on the contrary, surfaces having second group piezoelectric elements 4a, 4b, 5a, 5b are shrunk to be closed to internal sides. Accordingly, by driving elements 7a, 7b, a force to the right side is applied to the slider of a body to be moved. In the following half cycle, counter action is generated, and so surfaces having the first group piezoelectric elements 2a, 2b, 3a, 3b are closed to be shrunk, and by driving elements 6a, 6b, a force to the right side is applied to, and the slider is moved to the right side in the positive and negative cycles. As a result high output can be generated and a space can be saved.
