Title:
DISPLACEMENT REDUCTION METHOD AND DEVICE FOR MOTOR VIBRATOR, TERMINAL APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/021310
Kind Code:
A1
Abstract:
Disclosed in the present invention are a displacement reduction method and device for a motor vibrator, a terminal apparatus, and a computer-readable storage medium. The method comprises: by means of a terminal apparatus provided with a linear motor, predicting the maximum vibrator energy value of a vibrator of the linear motor according to a pre-driving voltage of the linear motor; according to the maximum vibrator energy value and preset maximum allowable energy of the vibrator, adjusting the pre-driving voltage to obtain the adjusted driving voltage; and, according to the adjusted driving voltage, driving the linear motor so as to reduce the displacement of the vibrator. The technical solution of the present invention ensures that the motor vibrator cannot collide with a motor housing during the process of moving under voltage driving, thereby effectively avoiding such problems as motor performance reduction, abnormal vibration feelings, loud vibration noise and motor damage caused thereby.
