Abstract
In a digital audio signal player having a simulated analogue record, a voltage dividing circuit is provided that consists of a first, and a second leads connected to a respective one of two separate wound wires of a control element; the control element can be turned to simulate an analogue record being moved by hands on the turntable for the player to play music with speed and speed changing according to movement of the control element. The microprocessor can decide that users' hands have touched the control element to complete the voltage dividing circuit, which is normally open, on detecting a voltage drop in order to make music played in the special mode. Music is played in an original normal way when the hand is removed from the control element for disappearance of the voltage drop.
