Abstract: A touchpad module for a computing device is provided. A fixing frame is concavely formed in a casing of the computing device. The fixing frame includes a supporting part. The touchpad module is installed within the fixing frame. The touchpad module includes a touch member and a pressure sensing element. The touch member includes a covering plate and a circuit board. An edge part of covering plate is supported on the supporting part. The pressure sensing element is installed on the touch member and electrically connected with the circuit board. While the touch member is pressed, the touch member is bent downwardly. Consequently, the touch member has a deformation amount. According to the deformation amount, a magnitude of a pressing force exerted on the touch member is sensed, and a pressure sensing signal is generated.

Abstract: A touch module includes a base plate, a magnet, a touchpad and a magnetic board. The magnetic board includes a first sensing line, a second sensing line, a third sensing line, a first communication part and a second communication part. The touchpad is located over the base plate. The magnetic board is arranged between the touchpad and the magnet. The first sensing line, the second sensing line and the third sensing line of the magnetic board are in parallel with each other and stacked on each other. The first sensing line is electrically connected with the second sensing line through the first communication part. The second sensing line is electrically connected with the third sensing line through the second communication part. The first sensing line, the second sensing line and the third sensing line sense a magnetic field of the magnet and generates a vibration.

Abstract: A touch module includes a base plate, a first magnet, a second magnet, a touch pad, a first magnetic board and a second magnetic board. The first magnet and the second magnet are installed on the base plate and separated from each other. The touch pad is located over the base plate to cover the first magnet and the second magnet. The first magnetic board and the second magnetic board are separated from each other, located under the touch pad and coupled with the touch pad. The first magnetic board is aligned with the first magnet. The second magnetic board is aligned with the second magnet. The driving circuit is electrically coupled with the first magnetic board and the second magnetic board. The first magnetic board induces a magnetic field of the first magnet. The second magnetic board induces a magnetic field of the second magnet.
