Abstract
A touchpad module includes a circuit board and a switch assembly. The switch element includes a conductive element and a metal dome. The conductive element is capable of providing buffering efficacy. The conductive element is arranged between the circuit board and the metal dome. When the metal dome is subjected to deformation, the metal dome does not collide with the circuit board to generate the click sound directly. Consequently, the comfort of operating the touchpad module is enhanced. The present invention further provides a computing device with the touchpad module.
Claims18
A touchpad module, comprising:
- a circuit board comprising a first contact part and a second contact part, wherein there is a horizontal spacing distance between the first contact part and the second contact part;
- and
- a switch assembly comprising:
- a first conductive element located under the circuit board, and contacted with the first contact part, wherein the first conductive element has an opening, and the first conductive element is made of conductive copper foil or conductive cloth;
- a metal dome;
- and
- a second conductive element arranged between the metal dome and the first conductive element, wherein there is a vertical spacing distance between the second conductive element and the second contact part,
- wherein when the touchpad module is pressed down and the switch assembly is moved downwardly to push a triggering part, the metal dome is subjected to deformation and contacted with the second conductive element, and at least a portion of the second conductive element is penetrated through the opening and contacted with the second contact part, so that the first contact part and the second contact part are electrically connected with each other.
A computing device, comprising:
- a casing, wherein a fixing frame is concavely formed in the casing;
