摘要： In a combined stylus and generator system, the combination with a stylus adapted to operate with a record groove and a generator moving in response to the movement of said stylus means for suspending the stylus and generator system for universal movement. The means for suspending the system includes a pivot member connected to a rigid support and seated in an elastomeric socket member proximate the end of the stylus lever. The pivot member is preloaded in the elastomeric socket member by a second elastomeric member coupled between the rear of the stylus lever and the support. Lateral motion of the generator system is damped by non-linear compressive forces in the preloaded elastomeric socket member, while forces on the stylus causing the generator system to swing about the pivot member are damped by opposing shear compliance forces in the elastomeric socket member which act to return the stylus to its neutral position.

摘要： An electro-magnetic cartridge for the reproduction of quadraphonic, stereophonic and/or monaural sound recordings has a balanced magnetic and electrical structure including a replaceable stylus lever-generator assembly which has front and rear pole piece extensions forming terminations of the opposite polarities of the magnetic structure cooperatively positioned to form first and second pairs of operating gaps with the generator extending at least partially into the operating gaps.
