CONSTITUTION: An upper member(5) and a lower member(6) are attached to an upper part and a lower part of a disc(4) having a predetermined area and a predetermined thickness. The upper member(5) and the lower member(6) have a hollow center with a predetermined area. An upper piezo-electric element(1) and a lower piezo-electric element are disposed on the inner side of the disc(4). An upper piezo electric element(3a) is spaced from the upper piezo-electric element(1) with a predetermined distance and disposed on the disc(4).
