ABSTRACT:
A sound pick-up for frequencies in the audible range, particularly for musical instruments have resonant cavities, such as string instruments, includes a housing which can be secured to the resonant body of the instrument and an induction coil whose connections extend outwardly through the housing. A wall portion of the housing connected to the resonant body supports the induction coil. The induction coil projects into an annular gap of a permanent magnet which is supported in a spring-elastic manner in the housing. The spring-elastic support of the permanent magnet makes it possible that the permanent magnet is movable in axial direction of the induction coil and relative to the housing.
