  • Patent number: 11909340
    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.

  • Patent number: 11264931
    Abstract: The invention provides a vibration controlling method which amplifies a steady state voltage and generates a first voltage signal for controlling the vibrator to accelerate vibration to a target vibration amplitude lower than the steady state vibration amplitude, and then attenuates the startup voltage to the steady state voltage to generate a second voltage signal for controlling the vibrator to vibrate from the target vibration amplitude to the steady state vibration amplitude. Through the implementation of the invention, the steady state voltage is amplified and used as an excitation voltage of the acceleration section of vibrator vibration, and then it steadily decreases to the steady state voltage, which effectively shortens the acceleration time for the early stage of the vibrator vibration response and reduces the hysteresis of the vibrator vibration fed back to the user.
