Direct Drive Transducer Operation:
Direct drive transducer devices do not have any included DC circuitry, so the user must apply a
sine or square wave with the appropriate rated frequency. A square wave will typically result in
more sound level than a sine wave. The higher the peak-to-peak voltage applied (up to the
maximum rated voltage), the higher the resulting sound level.
Frequency Response:
