Title:
超音波振動装置
Document Type and Number:
Japanese Patent JP5851147
Kind Code:
B2
Abstract:
Provided is an ultrasonic vibration device with which it is possible to efficiently remove fat by generating vibrations not only in the direction parallel to a probe but also in the direction orthogonal to the probe. Provided is an ultrasonic vibration device including a polygonal columnar elastic body formed of an elastic body; a piezoelectric element that is secured to a side surface of the polygonal columnar elastic body and that is polarized in a plate-thickness direction thereof; a rod-like contactor that is secured to an end portion of the polygonal columnar elastic body and that has a smaller diameter than the polygonal columnar elastic body; and a drive-pulse generating circuit that generates a bending vibration in the polygonal columnar elastic body by applying an AC voltage in the plate-thickness direction of the piezoelectric element, thus generating an ultrasonic vibration in the rod-like contactor.
