Abstract
An ultrasonic atomizer is provided with an ultrasonic converter ( ) with frequency-dependent impedance characteristic. A driver system is provided ( ) for generating driver signals for the ultrasound converter ( ) such that while the device can be handled in a simple manner, the liquid to be applied is atomized optimally. The driver system ( ) is connected such that a frequency set value with minimal driver current is sought immediately after the ultrasonic atomizer is put into operation by varying the frequency of the current signal.
