发明名称 Spring-suspension magnetically stabilized pick-up arm
摘要 The invention relates to a pick-up arm system for the reproduction or replay of records comprising a pick-up arm chassis and a pick-up arm tube. The torsion element suspension of the pick-up arm is axially stabilized by means of cylindrical permanent magnets which are arranged in a vertical direction and have opposite polarities, said elements forming a rotating bearing or a pivot. According to the invention, the torsion element runs in a congruent manner with respect to the vertical axis of rotation through the horizontal point of rotation of the receiving element for the tube of the pick-up arm. The lower part of the torsion element is connected to a permanent magnet which is connected to the receiving element for the pick-up arm or tube and the upper part of the torsion element is fixated attached to the upper chassis of the pick-up arm. A second permanent magnet or otherwise attached of opposite polarity is fixated in the lower chassis of the pick-up arm in a perpendicular position below said permanent magnet.
