In a digital audio signal player having a simulated analogue record, a high frequency
alternator is provided, which is connected to the microprocessor, and constantly
sends out a high-frequency signal; the alternator has an output terminal electrically
connected to a diode connected to the microprocessor; a control element is also
connected to the diode. Music is played in a normal way when the microprocessor
receives high-frequency signal in a non-reduced form. The control element will
send an interfering signal to the diode to reduce high frequency signal passing
through the diode when touched by hands, thus making the microprocessor receive
high frequency signal in reduced form; music is played with speed and direction
changing according to the movement of the control element when the microprocessor
receives the reduced high frequency signal. Music is played normally as soon as
hands are removed from the control element.
