PURPOSE:To obtain a winding oscillation converter which can eliminate the additional LC electric circuit by functioning as the low capacity ratio converter, by distributing the elastic plate and the piezoelectric ceramic plate connected virtically in the longer direction and setting the piezoelectric ceramic plate so that its polarization direction may be virtually vertical to the longer direction of the elastic plate. CONSTITUTION:Piezoelectric ceramic plate 21 which is polarized in the direction of arrow mark 23 is provided between the longer directions of elastic plates 19 and 20 made of the everlasting elastic material in such way that polarization direction 22 may be virtually vertical to the longer directions of plates 19 and 20. And the single- side end faces of plates 19 and 20 opposing to the both electrode faces of plate 21 are connected vertically via the adhesive such as the solder or the like into the tuning-bar shape. Support wires 26 and 27 attached to the node of the winding oscillation double the function of the lead wire. Furthermore, if the AC voltage of the fixed frequency is applied to wires 26 and 27, plate 21 features the thickness shear vibrations in the direction of arrows 23 and 24. By this vibration, the converter has the winding oscillation shown by the dotted line 25. |
