    Default Try a parallel choke instead...

    You will have more efficiency and volume by using a small choke (coil) across the piezo to better the resonance. Some experimentation with size (micro Henry) is needed but any will show the difference from none...

    edit... play safe and install a series resistor though, say 330 or 470 ohms.
