Abstract
The present disclosure relates to the technical field of electronic devices, and discloses a method and an apparatus for controlling motor vibration. The method includes: obtaining an input signal based on an expected motor vibration curve, inputting a digital signal sequence of the input signal to an equalizer, and obtaining an output signal after processing by the equalizer, and inputting the output signal to a motor to control vibration of the motor, where the equalizer is a digital filter constructed based on a damping factor ζ and a resonance frequency ωof the motor, and a preset system sampling frequency f, a preset damping factor ζ, and a preset cut-off frequency ω. The method and apparatus provided in embodiments of the present disclosure have an advantage that an actual vibration effect of the motor can be consistent with an expected motor vibration curve.
