<p>A structure capable of automatically supporting a nodal point of a piezoelectric stator is provided. The structure includes a piezoelectric stator constructed of at least one piezoelectric element and having at least one nodal point; at least one elastic member elastically contacting the piezoelectric stator via the piezoelectric element; a holder arranged around the piezoelectric stator and mounted with the elastic member; and a power supply for applying an electric field to the piezoelectric element via the elastic member. The elastic member automatically locates and contacts the nodal point of the piezoelectric stator owing to the strain of the piezoelectric stator when the electric field is applied to the piezoelectric element. As the nodal point of the piezoelectric stator is correctly supported, oscillation efficiency of the piezoelectric stator is maximized.</p> |
