Abstract

A method and device for generating vibrating signal is provided in the present disclosure. The method of generating a vibrating signal includes the following steps: S10 , generating one unit cycle of basic vibrating signals, wherein the unit cycle is less than a preset threshold; S20 , obtaining N unit cycles of vibrating sub-signals by using the basic vibrating signal as a parent and changing a signal parameter of the basic vibrating signal, wherein the N is a positive integer; and S30 , generating a vibrating signal according to the N unit cycles of vibrating sub-signals. The present invention can generate a vibrating signal that can start to stop immediately, and the vibrating signal can be more rich in constructing the vibration mode, more realistic to simulate the actual vibration, and can be used in a larger range.
