ABSTRACT:
The piezoelectric transducer saddle of the present invention is a thin, generally rectangular member that is designed to fit into the bridge slot of a musical instrument such as a guitar. The piezoelectric element is oriented vertically in the saddle and constitutes a structural member of the saddle. In a first embodiment of the saddle, a piezoelectric element forms the saddle itself. Electrical contacts are engaged to the sides of the piezoelectric element to produce electrical output. A preferred embodiment of the saddle is a laminated structure wherein the laminated layers are disposed vertically, and a vertical layer composed of a piezoelectric material is generally centrally disposed within the laminated structure. A metallic electrical contact is engaged on each side of the piezoelectric material to receive electrical signals generated by the piezoelectric material. In one embodiment, one of the electrical contacts is formed as a metallic layer which rises to the upper surface of the saddle to make contact with the strings of the musical instrument, in order to provide a ground for the metallic musical strings of the instrument. Further embodiments of the present invention utilize multiple piezoelectric elements and shaped piezoelectric elements to produce enhanced performance.
