Abstract
A bifunctional turntable which includes a rotating shaft, a platter, a light sensor module, an audio control module, and a plinth is revealed. The rotating shaft which is driven by a power source to rotate drives the platter to rotate. Then the light sensor module disposed on the rotating shaft detects rotation speed of the platter for playing a record at normal speed. The audio control module is located in the plinth and disposed on a simulated record for detecting changes in the simulated record which is manually operated. Then the audio control module sends signals to a digital audio control system at a rear end for driving the digital audio control system to output audio signals. Thereby the present turntable plays not only vinyl records but also simulated records.
