摘要:
A piezoelectric ceramic transformer has a rectangular parallelopiped piezoelectric ceramic plate divided into a generator section and driving sections on both sides of the generator section, and first ring-shaped input electrodes and second ring-shaped input electrodes are alternately put on the rectangular parallelopiped piezoelectric ceramic plate at intervals so as to create electric field perfectly oriented in the longitudinal direction of the ceramic plate.
