Abstract: A touch device includes a touch panel, a circuit board, a vibrating unit and a pressure detection module. The touch panel includes two press regions. When different press regions of the touch panel are pressed by the user, the vibration feedback values generated by different press regions are different.

Abstract: A touch feedback correction method and a touch module using the touch feedback correction method are provided. In the touch feedback correction method, the coordinate values and the initial vibration values of plural press region on a touch panel of the touch module are detected. Consequently, a driving voltage calibration table is established. Then, a vibrating unit of the touch module is driven according to plural compensated voltage values of the driving voltage calibration table. Consequently, the plural press regions generate plural corrected vibration values, respectively.

Abstract: A touchpad module includes a base plate, a touch member, a supporting structure and a pressure sensing unit. The touch member is movable toward the base plate. The supporting structure is arranged between the base plate and the touch member. The pressure sensing unit is installed on the touch member. The pressure sensing unit is arranged between the touch member and the base plate. While the touch member is pressed in response to an external pressing force, the touch member is moved downwardly toward the base plate to compress the supporting structure. Consequently, the supporting structure is subjected to deformation, and the touch member has a displacement amount. According to the displacement amount, a magnitude of the pressing force is sensed by the pressure sensing unit, and a pressure sensing signal is outputted from the pressure sensing unit.

Abstract: A touchpad module includes a base plate, a touch member, a switch, an elastic element, a first supporting element and a second supporting element. The base plate includes a triggering part. The touch member is located over the base plate. The switch is disposed on the touch member and aligned with the triggering part. The elastic element is located under the base plate. The elastic element includes a fixed part, a first swingable part and a second swingable part. The fixed part is fixed on the base plate. The first swingable part includes a first contact structure. The second swingable part includes a second contact structure. When an external force is exerted on the touch member, the touch member is swung toward the base plate relative to the first supporting element, and the second swingable part is swung away from the base plate.
