ABSTRACT:
In construction of a pickup unit used for electroacoustic conversion of various vibrations produced on a string instrument, a piezoelectric assembly clamped between a string holder and a bridge is provided with a dual layer arrangement of piezoelectric elements kept in contact with corresponding positive electrodes. The piezoelectric elements closer to the string holder detect string vibrations and the piezoelectric elements closer to the bridge detects body vibrations of the string instrument so that electric signals from piezoelectric elements of different groups can be tactfully blended together for rich and voluminous generation of musical tones over a wide tone range.
