Touchpad system with piezoelectric actuator

The touchpad assembly provides better consistency of user input and back tactile feedback by providing a plurality of piezoelectric actuators mounted on one side of the PCB, the plurality of piezoelectric actuators configured to produce electrical signals in response to a force being exerted by a user on a top touch surface located on the other side of the PCB. The control circuit is configured to: receive electrical signals from the plurality of piezoelectric actuators; determining a location of a force applied on the top touch surface; and generating a haptic response signal, which may be positioned based on the location at which the force is applied. 触控板组件通过设置有安装在PCB的一个侧部上的多个压电致动器来提供使用者输入和追逆触觉反馈的更佳的一致性，所述多个压电控制器被配置成响应于由使用者在位于PCB的另一侧部上的顶部触摸表面上施加力来生产电信号。控制电路被配置成：接收来自所述多个压电致动器的电信号；对在顶部触摸表面上施加的力的位置进行确定；以及生成触觉响应信号，该触觉响应信号可以基于施加力的位置而被定位。
