CROSS-TYPE PIEZOELECTRICITY GENERATOR CAPABLE OF SETTING THE SAME RESONANT FREQUENCY AND A VIBRATION MODE

摘要

PURPOSE: A cross-type piezoelectricity generator is provided to increase power amount by operating four cantilever generators using one vibrator at the same time.;CONSTITUTION: The center of a fixing unit generates vibration. A cross plate (14) connects four cantilever piezoelectricity generators in a cross shape. A piezoelectric member (12) is attached to each of the four sides of the plate. A mass (16) is attached to each of the four ends of the plate. The mass reduces the resonant frequency.;COPYRIGHT KIPO 2013
