Abstract
A touchpad module includes a base plate, a touch member, plural supporting elements, plural pressure sensing units and a feedback generation element. The base plate includes a plate body and plural elastic arms. The plural elastic arms are formed on the plate body. The plural supporting elements are arranged between the base plate and the touch member, and aligned with the corresponding elastic arms. While the touch member is moved toward the base plate, the plural supporting elements are move downwardly with the touch member to press the corresponding elastic arms. Consequently, the plural elastic arms are subjected to deformation. If the deformation amount of at least one of the plural elastic arms reaches a threshold value, the corresponding pressure sensing unit issues a pressure sensing signal. The feedback generation element generates a haptics feedback effect in response to the pressure sensing signal.
