音響再生装置。 Rotation begins due to the centrifugal force generated when the whole unit is rotated in the direction along the conical surface, and rotation stops when the centrifugal force is lost.The driving vertical shaft is provided with a weighted arm that rotates, and the rotational force of the driving shaft. A rotating turntable, a record fixed to the turntable, a pressing coil spring provided to apply a pressing force to the record, a speaker disposed below the record, and a record. and the speaker, the needle is engaged with the sound groove of the record, and the engagement is disengaged when the record moves upward, and the boss is in contact with the back plate of the record. A pick-up with a spring, a driven cam with a portion protruding downward provided at the center of the bottom of the turntable, and a trajectory of the driven cam when pressed by the tip of the pick-up between the tip of the pick-up and the driven cam. 1. A sound reproducing device comprising: a driving cam that moves inside the pickup to push up the turntable and moves out of the trajectory of the driven cam when the pressure from the tip of the pickup is released.
