Abstract
A driving mechanism for a record player includes a fixing base, a solenoid, a housing, a spindle, a sleeve, a turntable and a magnetic ring. The solenoid is fixed on the fixing base for rotating the housing. The spindle is located in the center of the housing and extends upward through the sleeve fixed in a center hole of the turntable. The magnetic ring is fixed under the lower surface of the turntable and faces the upper surface of the housing with an aperture, producing strong magnetism against the housing. Thus, the turntable is pulled down-ward to increase tightness between itself and the sleeve so that the turntable may rotate synchronously with the spindle, preventing inertia torque and slide difference between the turntable and the spindle.
