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.

Abstract: A vibration motor includes: a shell having an inner cavity; a vibrator; a magnetic component configured to drive the vibrator to vibrate; a first coil fixed to the shell; and a second coil fixed to the magnetic component. An alternating current applied to the first coil makes the vibrator to vibrate along the inner cavity. An adjustable current applied to the second coil makes a magnetic field of the magnetic component repel a magnetic field of the vibrator and provide a restoring force for the vibrator to reciprocate. A magnitude of the restoring force generated by the magnetic component is changed by adjusting a magnitude of the magnetic field of the magnetic component, to adjust a resonance frequency of the vibrator when the vibrator is vibrating. The resonance frequency of the vibration motor can be adjusted so that the vibration motor can have sufficiently high response in a wide frequency band.
