Capacitive ultrasonic transducers are widely used to generate airborne ultrasound. This paper presents an equivalent circuit for an electrostatic transducer with a V-grooved backplate. The comparison ...

An optimization design strategy is developed for ultrasonic transducer (UT) with multimatching layer to improve its performance. The piezoelectric equivalent circuit model is used to determine the ...

The circuit is designed for atomizing transducers, which have a resonant frequency of 113 KHz — much higher than your average junk box piezo. Check out the demo and build video after the break.
