Abstract
A transducer for a stringed musical instrument incorporating an electrically conductive ground plane, along with a piezoelectric transducer and a conductive strip. The piezoelectric transducer is comprised of a polyvinylidene fluoride co-polymer. The ground plane, piezoelectric transducers and conductive strip are secured in an elongated unitary structure with the ground plane and conductive strip disposed on opposite sides of the transducers. A conductive shield is disposed about the unitary structure and electrical leads connect to the ground plane and conductive strip, respectively. The conductive strip and ground plane are both of a flexible material with a dielectric layer and a metallic layer. The conductive strip and ground plane extend beyond the piezoelectric transducer to form leads for the transducer.

A transducer assembly for a stringed musical instrument comprising:
- an elongated transducer;
- a flexible conductive member conductively contacting a first surface on the elongated transducer, the flexible conductive member extending beyond the elongated transducer in a direction perpendicular to the first surface to form a conductive lead portion;
- a flexible conductive ground member encircling the flexible conductive member and elongated transducer, the ground member being electrically insulated from the conductive member and a portion of the ground member encircling the conductive lead portion forming a ground lead portion.
The transducer of claim. 1, wherein the elongated transducer includes a plurality of individual piezoelectric crystals.
A transducer assembly for a stringed musical instrument comprising:
- an elongated transducer;
- a flexible conductive member conductively contacting a first surface on the elongated transducer, the flexible conductive member extending beyond the elongated transducer and being flexible near the elongated transducer so that it can be bent in a direction transverse to the first surface to form a conductive lead portion;
- a flexible conductive ground member substantially surrounding the flexible conductive member and elongated transducer to provide a shielding layer, the ground member being electrically insulated from the conductive member, and a portion of the ground member substantially surrounding the conductive lead portion forming a ground lead portion.
