PHONOGRAPH ACTUATED ELEMENTS A magnetizing disc for use with a phonograph having a cover positionable over a turntable and in fixed parallel relationship with the turntable. The cover of the phonograph is made of a non-magnetizable material. The disc has one or more magnets secured to an upper face thereof. A drive post is secured to the disc and engageable with the turntable to impart a rotational drive to the disc and to space the disc above the turntable whereby to cause displacement of magnetically attractable elements disposed on the cover when the turntable is rotated with the cover positioned thereover.
