Pickup apparatus for an electric string type instrument

Pickup means for electric string-type instrument, which instrument comprises a frame and a plurality of strings mounted on a frame, each string producing a note;

• said pickup means comprising:
• a plurality of individual elastic elongated pickups, each pickup comprising:
• an elastic, cylindrical piezo-electric member, said piezo-electric member being prepared by mixing a high molecular material with a piezo-electric ceramic powder and a vulcanizing agent, said piezo-electric member being polarized;
• a pair of electrodes on said piezo-electric member, one of said electrodes comprising a lead wire embedded axially in said piezo-electric member, the other electrode being mounted on the circumferential periphery of said piezo-electric member;
• and
• an insulating member encasing said piezo-electric member and said pair of electrodes, said elastic member having an upper non-planar surface;
• and
• a bridge member directly mounted on the upper non-planar surfaces of the plurality of pickups, the pickups being disposed longitudinally parallel to one another;
• the pickup means being directly interposed between said strings and said frame, with said pickups resting on said frame so that the plurality of pickups and the bridge member extend to support plural strings covering plural notes of the instrument so as to be common thereto.
