WebIt works better at low frequencies, and this is why a loudspeaker standing in free air without a closed box behind it has no bass. Your piezo is much smaller, but it has the same problem. Using the enclosure as I said above solves this. Drive the piezo with a H-bridge, for example a 74HC six-inverter chip with 3 inverters per side. Web24 feb. 2024 · Say you have a piezo disc with a natural resonant frequency of 4000 Hz but you want a tone at 125 Hz. Your desired frequency is in the ratio 1:32 of the natural resonant frequency. Here is what you do: Make a square wave at 4000 Hz to drive the transducer. One time in every 32 square waves, inhibit the pulse.
