ABSTRACT:
A phonograph pick-up or cutter has a stylus holder carrying a stylus, which cooperates with two transducers, one for each of two orthogonal directions of vibration. Each transducer has a flat coil and an associated magnet having their axes in line. For each transducer the direction of relative movement of the coil to the magnet corresponds to the direction of the coil axis and the magnetic axis. The stylus holder is connected to the moving parts of the two transducers by a coupling member. Preferably, the moving part is arranged on a support connected to the stationary part, to minimize undesired transverse movements.
