Abstract
The present invention provides a driving voltage generation method of a linear motor, and linear motor driving voltage generation device performing same. The driving voltage voltage generation method of a linear motor includes the following. Define the displacement waveform of the linear motor's vibrator within a preset period and the displacement waveform is an asymmetrical waveform. Calculate the voltage waveform corresponding to the linear motor in the preset period according to the displacement waveform. The present invention is designed to use the driving voltage generated by the driving voltage generation method to effectively control the linear motor to express the vibration effect in a specific direction.
