Abstract
A phonograph record player including a speaker, a turntable and resettable tone arm. The speaker is fixedly secured to the casing of the record player and the tone arm is in contact with the speaker and the record as the record is being played. The turntable is mounted on a spindle carried by a transversely extending cantilever arm which is either attached to the base of the casing of the record player or is an integral part of the said casing. The cantilever arm arrangement enables the turntable to move resiliently in all directions being only restricted by the needle point thus providing a relatively stiff coupling arrangement between the record, the turntable and the speaker. The tone arm, which is radially spring biased, is maintained against the action of the spring in the grooves of the record throughout play of the record and by the central portion of the record when play is completed. The record is normally urged into contact with the tone arm by the pressure of the cantilever arm. The aforesaid cantilever arrangement also enables the turntable to be depressed to permit the record to become disengaged from the tone arm so that the tone arm will return to its starting position.
