Abstract
A Combo system and a method of driving the Combo system are provided. The Combo system includes a loudspeaker, a motor, an analog frequency divider, a power amplifier, a signal fuser, a nonlinear compensator, and a frequency-division predictor. The nonlinear compensator pre-distorts a digital signal of the loudspeaker to obtain a loudspeaker pre-distorted digital signal. The signal fuser fuses the loudspeaker pre-distorted digital signal with a digital signal of the motor to obtain a fused digital signal. The frequency-division predictor predicts voltage data loaded on two ends of the loudspeaker if the fused digital signal is transmitted to the analog frequency divider and divided by the analog frequency divider. The nonlinear compensator corrects the loudspeaker pre-distorted digital signal based on the voltage data to enable the loudspeaker analog signal to be consistent with the loudspeaker pre-distorted digital signal.
