Abstract
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.
