An atomizing apparatus comprises a body having a chamber into which liquid is supplied. A nozzle member is secured to the body to define a front vibrating member of said of the chamber, the nozzle member having at least one nozzle opening. A capacitive piezoelectric transducer is secured to the nozzle member for producing pressure rises in the liquid to cause the portion of the liquid in proximity to the nozzle opening to be ejected therethrough to the outside. The piezoelectric transducer is connected to an inductance element to form a resonant circuit. An amplifier is connected with the resonant circuit to form a self-oscillating loop to amplify the signal in the loop to sustain oscillation at a frequency variable as a function of the temperature-dependent capacitance of the piezoelectric transducer.
