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.

Inhaler

An inhaler includes an atomizing unit including a piezoelectric element substrate having a first IDT including a pair of interlocking comb-shaped electrodes. The atomizing unit is configured to atomize liquid by a surface acoustic wave generated by applying a high-frequency voltage to the pair of interlocking comb-shaped electrodes, and a controller is configured to monitor a resonant frequency of the pair of interlocking comb-shaped electrodes and apply a voltage to the pair of interlocking comb-shaped electrodes at a frequency determined based on the monitored resonant frequency.

A inhaler includes a piezoelectric element substrate having an IDT constructed by use of a pair of interlocking comb-shaped metallic electrodes, a liquid supplier for supplying liquid, which is to be atomized, to a front surface of the piezoelectric element substrate on which the pair of interlocking comb-shaped metallic electrodes is positioned, a sensor, which includes at least a pair of detection parts which are opposite to each other, for detecting liquid supplied to the front surface of the piezoelectric element substrate, and a controller for controlling, based on result of detection by the sensor, the liquid supplier in such a manner that the liquid supplier supplies a certain quantity of the liquid to the front surface of the piezoelectric element substrate.
