摘要
The record player for recording talking dolls will transfer mechanical oscillations of the pick-up arm to a loud-speaker membrane to correspond with the record modulation, while eliminating slow interference oscillations. The pick-up arm which is arranged between the rotating record and the loudspeaker is in the form of a two-armed movable lever. The upper lever arm has a holder for the stylus and on its opposite side a transmission stud which rests on a plastic disc attached to the loudspeaker membrane. A U-shaped leaf spring at the opposite end of the pick up arm from the stylus is attached to the underside and grips underneath the plastid disc to ensure that good contact is maintained.
