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 transducer may also include two piezoelectric transducers and conductive strips to provide two different outputs from the transducer. The two piezoelectric transducers may have different frequency response characteristics or may be connected to different signal processing circuits to allow for distinct modulations and mixing of outputs.
