Abstract

Provided is a dynamic protection method and system for a linear vibration motor. The method includes S: calculating original voltage signal according to initial gain coefficient; S: processing the original voltage signal of each frame, and obtaining driving voltage signal; S: loading the driving voltage signal to the linear vibration motor to drive the linear vibration motor to operate; S: collecting acceleration signal of the linear vibration motor, and analyzing whether the acceleration signal is abnormal to determine operating state of the linear vibration motor; if yes, performing S; and if not, performing S; S: adjusting current gain coefficient of current signal frame to new gain coefficient; and S: determining whether the current signal frame is the last signal frame. With this method, voltage parameter can be automatically adjusted for the linear vibration motor to reduce abnormal noise to prolong the service life of the device.
