## Abstract

A motor vibration method and a motor vibration device are provided. The motor vibration method includes: receiving a vibration instruction, and acquiring target environmental data by a preset sensor, wherein the target environmental data includes one or more of environmental noise data, acceleration data and/or pressure data; determining a first vibration signal according to the target environmental data; generating a target vibration signal according to the first vibration signal and a preset second vibration signal, wherein a first frequency of the first vibration signal is greater than a second frequency of the second vibration signal; and controlling the motor to vibrate according to the target vibration signal. The method combines a traditional vibration reminding effect and a sound reminding effect provided by adding the medium- and high-frequency signal, thereby enhancing the reminding efficiency by means of motor vibration and increasing the successful rate of message delivery.
