Vibration controlling method for vibrator, control device and computer readable storage medium

A control device, including:

• an obtaining module for obtaining an initial voltage signal for continuously outputting a steady state voltage within the effect duration of signal;
• a first generation module for amplifying the steady state voltage as a startup voltage according to a preset fixed amplification factor and generating the a voltage signal according to the startup voltage for controlling the vibrator to accelerate vibration to a target vibration amplitude lower than the steady state vibration amplitude;
• the value of the fixed amplification factor being more than 1;
• a second generation module for attenuating the startup voltage to the steady state voltage based on the function with the monotone decreasing interval, and generating a second voltage signal for controlling the vibrator from the target vibration amplitude vibration to the steady state vibration amplitude;
• a third generation module for generating the steady state voltage signal based on the steady state voltage of a preset continuance duration for controlling the vibrator to maintain vibration with the steady state vibration amplitude, a sum of the effect duration of the first voltage signal, the second voltage signal and the steady state voltage signal being equal to the effect duration of the initial voltage signal;
• a control module for generating a target voltage signal based on the first voltage signal, the second voltage signal and the steady state voltage signal;
• wherein the vibration is controlled according to the target voltage signal.
