DRIVING VOLTAGE GENERATION METHOD AND APPARATUS, AND STORAGE MEDIUM, AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/248849

Kind Code:

A1

Abstract:

A driving voltage generation method and apparatus, and a storage medium, and an electronic device. The method comprises: obtaining a standard acceleration and a standard resonance frequency (101); obtaining an actual resonance frequency (102); determining a relationship between the obtained actual resonance frequency and the standard resonance frequency (103); performing, according to a determination result, calibration calculation on an obtained standard acceleration waveform to generate a calibrated acceleration waveform (104); and generating a driving voltage according to an acceleration corresponding to the calibrated acceleration waveform (105). Calibration calculation is performed on the obtained standard acceleration waveform, the driving voltage is generated according to the acceleration corresponding to the calibrated acceleration waveform generated after the calculation, and different driving motors are driven according to different driving voltages, so that different driving motors can achieve the same tactile effect.
