ATOMIZING OSCILLATORY ELEMENT, ATOMIZING UNIT, ATOMIZING DEVICE, AND DRIVE METHOD FOR ATOMIZING DEVICE

摘要

The purpose of this invention is to provide an atomizing oscillatory element that can achieve suitable atomization in accordance with the level of liquid in a liquid storage tank, an atomizing unit, an atomizing device, and a drive method for atomizing device. To achieve this purpose, this atomizing oscillatory element 10 comprises a plate-like piezoelectric oscillator 11 and electrodes provided on each of one face 11b and other face 11a of the piezoelectric oscillator 11, wherein the electrodes provided on the one face 11b comprise a central electrode 21 arranged in the center portion of the piezoelectric oscillator 11 and an annular outer circumferential electrode 22 disposed so as to surround the circumference of the central electrode 21 in electrical isolation from the central electrode 21.
