Abstract
An audio signal player includes a turntable unit, a conductive touch-control plate on top of the turntable unit, a round disk, a round disk central shaft made of electricity-conductive materials and joined to the touch-control plate, a reflective-type photoelectric interrupter secured in the touch-control plate for finding out rotational speed and direction of the round disk, and a photoelectric interrupter in a lower end of the turntable unit for finding out rotational speed and direction of the turntable unit; when the round disk is manually rotated, the audio signal player will produce scratch sound effects according to the rotational speed and direction of the round disk; the user is allowed to touch the touch-control plate so as to produce a touch signal, thus making the audio signal player produce a particular scratch sound effect according to the touch signal.
