I am driving my audio with a pull down logic and a resistor and cap to 
vcc.  I had trouble getting mine to shut up when the driver was off so 
i put a resistor across the buzzer inputs to help drain off any leakage.
Murata makes lots of these devices and they should be loud with just a 
resistor to vcc and a ground logic pulling down the minus side of the 
device.
