Abstract
A digital audio signal reproducing device includes a system processor, a first rotation disk, a second rotation disk, a first sensor, a second sensor, and a lighting assembly. The first sensor detects rotation speed and direction of the first rotation disk to output a first control signal. The second sensor detects the second rotation disk being pressed to output a second control signal. When the first control signal and the second control signal are outputted to the system processor simultaneously, the lighting assembly is controlled by the system processor to perform a first blinking mode, and when only the first control signal is outputted to the system processor, the lighting assembly is controlled by the system processor to perform a second blinking mode.
