Abstract: A transducer has an input and produces a mechanical output, wherein the magnitude of the mechanical output of the transducer is dependent on the frequency and magnitude of current at the input. A driver for the transducer includes a device having a transfer function associated with the device, the device having a device input and a device output, the device output being connectable to the input of the transducer and the device input being connectable to a power source. The device attenuates the current output at a frequency that causes a peak in the magnitude of the mechanical output of the transducer.
