Abstract
The present invention provides a linear motor driving voltage generation method and related devices. The object is 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. The method of an embodiment of the present invention includes: determining the system gain and current phase of the linear motor system, obtaining the target acceleration and amplitude of initial value of the linear motor, calculating the driving based on the target acceleration and the initial value amplitude, the system gain, and the current phase.
