Abstract: A touchpad module includes a base plate, a touch member and at least one pressure sensing module. The touch member is located over the base plate. The touch member includes a touch plate and a touch sensitive circuit board. The pressure sensing module is arranged between the base plate and the touch member. The pressure sensing module includes a pressure sensor and a miniature supporting plate. The pressure sensor is installed on the miniature supporting plate. The pressure sensor is electrically connected with the touch sensitive circuit board through the miniature supporting plate. While the touch member is pressed in response to an external pressing force, the pressing force exerted on the touch member is sensed by the at least one pressure sensing module, and the pressure sensing module generates a pressure sensing signal.

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 touchpad module includes a touch member, a base plate, a supporting element and a switch. The touch member includes a first touch region and a second touch region. The base plate is located under the touch member. The supporting element is arranged between the touch member and the base plate. The supporting element is aligned with the second touch region. The switch is arranged between the touch member and the base plate. The switch is aligned with the second touch region. When a pressing force is applied to the second touch region of the touch member, the pressing force is transmitted to the base plate through the supporting element. Consequently, the base plate is subjected to deformation. The switch is triggered in response to the deformation of the base plate.

Abstract: A housing structure for an electronic device includes a light-transmissible housing body, a first light-shielding layer, a second light-shielding layer, a protective layer and an engraved trench. The first light-shielding layer is formed on a second surface of the light-transmissible housing body. The engraved trench is formed in the second surface of the light-transmissible housing body and not covered by the first light-shielding layer. The second light-shielding layer is formed on a first surface of the light-transmissible housing body. The protective layer is formed over the second light-shielding layer. A pattern corresponding to the engraved trench is visible.
