Abstract
A controller for controlling an atomizing unit, wherein the atomizing unit includes a piezoelectric element substrate including an IDT including a pair of interlocking comb-shaped metallic electrodes, and a liquid supplier configured to supply liquid, which is to be atomized, to the piezoelectric element substrate; wherein the piezoelectric element substrate is configured to atomize the liquid by use of a surface acoustic wave generated by applying a high-frequency voltage to the pair of interlocking comb-shaped metallic electrodes; and the controller is configured to periodically change amplitude and/or a frequency of the high-frequency voltage applied to the pair of interlocking comb-shaped metallic electrodes.
