    Abstract: A phonograph of the type wherein a plastics-made tone arm having an upstanding stylus mounted thereon is pivoted eccentrically on a turntable or rotor, under which a speaker is mounted concentrically for simultaneous rotation therewith relative to a record immovably supported above the turntable. Also mounted on the turntable is a metal-made vibration transmitter rod which is substantially pivotally supported at one end and which rests, at a point intermediate both ends thereof, on the armature of the speaker partly exposed through an aperture in the turntable. The tone arm has its free end resting on the vibration transmitter rod for sliding movement, during playback, from the other end of the rod toward its point of contact with the speaker armature.
