Abstract
The invention is an improved noise-making device using a piezoelectric transducer where electrical circuit components are mounted directly on the transducer itself rather than being mounted on a separate printed circuit board. Directly mounting the components eliminates the need for a separate circuit board and eliminates a third terminal from a three-terminal device. As a result, the entire device requires less material and labor, and is therefore less expensive. The elimination of the circuit board also can contribute to a reduction in size of the noise-making device.
