发明名称 Pickup
摘要 A phonograph pickup comprises the end portion of a cylindrical pole leg and an opposing yoke with an air gap therebetween, and a moving system including a stylus arm and an armature. A pivoting means provides for pivotal mounting of the moving system in the air gap, and comprises a first resilient bearing spaced a first distance from the pivot point for supporting the armature, and a second resilient bearing spaced a second distance (greater than the first distance) from the pivot point for engaging the moving system with a lower pressure than the first resilient bearing.
