ABSTRACT:
A piezoelectric bridge sound pick-up string instruments has a separate subassembly for each string. Each subassembly has a metal base body (4) with a pocket (4.1) for a piezoelectric sensor element (7), a sensor holder (5) and a pressure piece (8). The pocket is at right angles to the string and is tilted in accordance with the string pressure direction. The sensor element is embedded in an electrically insulating holder, which has a break in its central area (6) and allows a certain deflection of the sensor element. To an electrode on the under surface of the sensor element is fitted a conductor (9) for passing out a signal with positive potential. On an opposite, upper electrode surface is provided a pressure piece with a semi-circular cross-section, which transfers by friction the alternating pressure of the string (14) and functions as an electrical connection of ground potential.
