Abstract

PURPOSE:To improve linearity between speed displacement at a stylus tip and variation in voltage by employing the structure with a moving magnet placed direct in a coil. CONSTITUTION:To one terminal of cantilever 11 with stylus 12, moving magnets 13 and 14 are provided in parallel along the axial direction of cantilever 11, thereby constituting a vibrator. The magnetic axes of moving magnets 13 and 14 are perpendicular to the axis of cantilever 11 and cross each other at right angles. Further, moving magnets 13 and 14 are confronted each other with their magnetic axes tilting against the horizontal surface (record surface) at an angle of 45 deg.. This vibrator is supported to the coil bobbin made of a non-magnetic material by damper 15. Coil bobbin 18 is wound with coils 16 and 17 for left and right channels and its outer circumference is covered with support case 19 made of a magnetic material.
