A turntable having multiple-point touch function for a digital sound-signal device includes a base formed with a central insert hole having a lower side provided with a load sensor, with a photo-sensor installed at one inner end of the base. A multiple-point touch-induction circuit is fixed on the base, having different sensing regions and bored with a central through hole. A touch-control turntable assembled on the circuit board has a central post protruding downward to be inserted through both the through hole and the insert hole for combining the base, the circuit board and the turntable together, the combining post having its lower end touching the load sensor. The turntable has its outer end edge provided with lots of light-obstructing plates protruding downward for obstructing light with the photo-sensor. The touch-control turntable is preset with plural memory regions to be touched for outputting different sound effects.
