发明名称 Vibration free turntable apparatus
摘要 A platform that is magnetically suspended relative to a base. Magnet members are deployed atop and about the periphery of the base in fixedly secured relation thereto and oppositely polarized magnet members are secured to the bottom and about the periphery of the platform so that a magnetic repulsion exists between such magnet members in sufficient intensity to maintain the platform in suspended relation above the base. Taut guy wires disposed about the respective perimeters of the platform and the base maintain the base and platform in their cooperative dispositions. The base is provided with a plurality of upstanding post members and the platform is provided with a plurality of depending post members. The guy wires are grouped in pairs, and opposite ends of the guy wires in each pair are fixedly secured to different ones of the base and platform post members so that the platform does not slip out of the magnetic field. A turntable and tone arm may be employed to provide a record playing apparatus that is substantially vibration free.
