Pick-up for musical instruments e.g. stringed instruments like guitar, has printed circuit board with conductive strip whereby electrical signals are generated with string vibrations by capacitive charge transfer

摘要

Pick-up (TA) has printed circuit board (M3) with a conductive strip (M31). A dielectric of multi-layer body (M) is connected, in the form of pressure-transferring insulating layer (M2), between the conductive strip of the printed circuit board as a first capacitive coating and the PVDF foil as opposite second capacitive coating. Electrical signals are generated with string (13) vibrations by capacitive charge transfer. Pick-up has a capacitive PVDF foil transducer, resulting due to the prevention of a direct contact between the PVDF foil and the conductive strip of the printed circuit board.
