ABSTRACT:
A vibrator is disclosed having a vibrating body with a polygonal lateral cross-section. Two piezoelectric elements are disposed on nonparallel side surfaces of the vibrating body. A support structure is provided which supports the vibrating body at two support points of the vibrating body. The support points are located in a split plane which passes through the line of intersection of the two planes in which the two side surfaces lie and bisects the inner angle formed by these two planes. Furthermore, the support points are located on opposite sides of the vibrating body and each support point is located at or near a nodal point of the vibrator.
