SUPPORTING MEANS FOR PIEZOELECTRIC TRANSFORMERS

摘要

In a piezoelectric transformer comprising a ceramic body in the form of an elongate plate of piezoelectric material with one half polarized in the direction of thickness and the remaining half in the longitudinal direction, a pair of input electrodes secured to the opposite sides of said one half and an output electrode secured to the end surface of the remaining half, there is provided supporting means including means for mechanically clamping and supporting the piezoelectric transformer at at least one of the transverse line nodes of the longitudinal mechanical vibrational movement thereof which support permits free longitudinal vibrations while suppressing undesirable vibrating modes.
