A common enhancement to this circuit replaces R2 with an inductor as shown in Figure 2. Figure 2 Substituting an inductor for R2 improves the piezo driver’s output and efficiency. Often the inductance ...

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.

The Synaptics Resonate amplifier drives a piezo transducer element attached to the back of a display and vibrate the display to produce audio. Synaptics highlighted its Synaptics Resonate audio ...

The challenge here is in designing piezoelectric transducers that can produce very-high-quality sound within a small package, and without draining too much of the device’s battery. Medical ...

The Indiana Department of Transportation (INDOT) tasked a team of Purdue University engineers with collecting data on concrete maturity through select highway patching and paving projects. The ...
