Claim 7:
8. The vibrator driving method as described in claim 1, wherein the steps of obtaining the preset vibration frequency and the resonant frequency of the target vibration motor and obtaining total harmonic distortion of the target vibration motor include:
obtaining a digital drive signal, converting the digital drive into an analog driving signal, amplifying the analog driving signal to obtain a target driving signal, and inputting the target driving signal to the target vibration motor to drive the target vibration motor;
obtaining acceleration of a target tooling in a preset vibration direction, wherein the target vibration motor is attached to the target tooling;
obtaining the resonant frequency and the total harmonic distortion according to the target driving voltage corresponding to the target driving signal and the acceleration in the preset vibration direction.
