With just half-an-H-bridge square wave drive, the transistors must charge and discharge that parallel equivalent capacitor on each half cycle.That equivalent circuit as described above is going to have two resonances: series tuned and parallel tuned resonance. A square wave drive through a series tuned circuit is fine because a series tuned LC circuit presents a high impedance to the harmonics contained in the square wave.Whereas a parallel tuned circuit presents a -low- impedance to the harmonics, causing losses in the drive transistors.A bare piezoelectric ultrasonic transducer's equivalent circuit is a capacitor in parallel with a series-tuned LCR circuit. Piezo Ceramic Ultrasonic and Piezo Piezo Ceramic Ultrasonic and PiezoPiezoelectric ceramic wafer is a kind of simple and lightweight electrical device. It has been widely used because of its high sensitivity, no magnetic field spillover, no copper wire and magnet, low cost, low power consumption, easy to mass production and other advantages.
If you have all the transducers driven at exactly the same frequency and with zero (or constant) phase difference, then you will get standing waves caused by interference between them. Upon reflection, the problems I've listed shouldn't be an issue at those frequencies.The wavelength of 40kHz ultrasound in water is about 8.5mm. Now imagine cavitation going on inside your hand if you reach into a running ultrasonic cleaner.I guess that was a stupid question then! Not long, 4-50mm. Note that this video suggests a test that results in a layer of aluminum foil being destroyed. Probably not those crappy plastic "jewelry cleaners", but the higher powered ones. The lower power designs mostly just get away with overrating the components and driving with a raw square wave.I must add that an ultrasonic cleaner is potentially hazardous.
