Title:
PIEZOELECTRIC TOUCH CONTROL APPARATUS, METHOD AND APPARATUS FOR CONTROLLING FEEDBACK VIBRATION THEREOF, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/227815
Kind Code:
A1
Abstract:
A piezoelectric touch control apparatus, a method and an apparatus for controlling the feedback vibration thereof, and an electronic device: when a user touches a touch control panel of the piezoelectric touch control apparatus, a feedback controller of the piezoelectric electric touch control apparatus can obtain a corresponding touch control area on the basis of touch control position information of the current touch control point of the user, then match the corresponding touch control area to a preset excitation signal database to obtain the required piezoelectric excitation signal corresponding to the touch control point, and then control the operation of a piezoelectric motor on the basis of the piezoelectric excitation signal in order to implement feedback vibration.
