Abstract
A transducer for a stringed musical instrument incorporating an electrically conductive ground plane, along with a plurality of piezoelectric transducers and a conductive strip. 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 made of paper with a conductive coating is disposed about the unitary structure and electrical leads connect to the ground plane and conductive strip, respectively.
Claims6
A method of fabricating a stringed instrument transducer that is adapted to be positioned adjacent the instrument strings to receive acoustic vibratory signals therefrom, said method comprising the steps of, providing an electrically conductive ground plane, providing a conductive strip, disposing a plurality of piezoelectric crystals sandwiched between the conductive ground plane and conductive strip so as to provide an elongated unitary structure and with the crystals disposed so as to be in alignment with respective strings when installed in the musical instrument, wrapping a paper product about the unitary structure and painting the paper with a conductive paint so as to form a shield about the structure, and connecting electrical leads to the ground plane and conductive strip, respectively.
