Abstract

PURPOSE:To obtain a miniature and lightweight cartridge of high magnetic efficiency, by allowing moving coils to cross the magnetic flux from magnets. CONSTITUTION:To one terminal of cantilever 12 with stylus 11, coil bobbin 15 of a nonmagnetic material wound with moving coils 13 and 14 is fitted, thereby constituting the vibration system. Magnets 16 and 17 are arranged on spacer 20 of a nonmagnetic material inside of support body 19 of a magnetic material confronting each other with angles of approximate 45 deg. against the horizontal surface so that their magnetic axes will be perpendicular mutually and cross the axial direction of cantilever 12 at right angles. Then, magnets 16 and 17 are equipped with coil bobbin 15 via damper 18 and respective coils 13 and 14, arranged confronting to magnets 16 and 17, are covered with support body 19.
