ABSTRACT:
A simplified sound reproducing device in which the stylus force of a reproducing stylus is imparted by a stylus pressure spring, the weight of the turn table being independently supported so that only the weight of the stylus and related tone arm are impinged upon the record to be reproduced. The stylus force imparted by the stylus pressure spring permits the stylus to remain in contact with the record disc following its undulations and reproducing high quality sounds.
