  • Patent number: 6248947
    Abstract: A transducer for musical instruments formed as a sandwich structure that utilizes a length of polarized fluoropolymer polyvinylidene fluoride (PVDF) film folded over itself to form a U-shape over a center conductor of a length of shielded coaxial cable. Conductive silver epoxy is used to attach the center conductor of the coaxial cable to the inner surface electrode of the PVDF film. A length of double-sided tape is sandwiched between the two legs of the U-shaped PVDF film. The free end of the coaxial cable is folded over a side edge of the U-shaped PVDF film such that an outer shield of the coaxial cable is exposed outside the PVDF film. A U-shaped brass channel, whose inner surface has been coated with conductive epoxy, is then crimped over both the outer shield of the coaxial cable and the U-shaped end of the laminated PVDF film to form a transducer assembly, which is then laminated to a length of double-sided tape having an outer removable backing layer.
