  • Patent number: 11164707
    Abstract: The invention provides a touch device and an input module. The touch device includes a cover plate, a circuit board, a restoration element, a bracket, at least one conductive pad, and a buffer layer. The circuit board is disposed on one side of the cover plate and has a first surface facing the cover plate, a second surface opposite to the first surface, and at least one conductive switch disposed on the second surface. The bracket is disposed on the second surface of the circuit board. The restoration element is disposed on the second surface, and the conductive pad is disposed on the bracket and located between the bracket and the circuit board. The conductive pad and the restoration element are separately disposed, and the conductive pad corresponds to the conductive switch. The buffer layer is disposed between the second surface and the restoration element.

  • Patent number: 8803804
    Abstract: The invention discloses a mouse structure with click force adjustable function, which comprises a shell, a circuit board module, and at least one adjustable mechanism. The adjustable mechanism is setting inside the shell, and comprises a supporting body, an adjustable plate and an adjustable component. The adjustable mechanism is adjusted via the adjustable component, so that the place the free-end of the adjustable plate touching the key portion is changed, and the force the adjustable plate clicking the switch module is accordingly changed, which provides function that the user can adjust the click force finely to a suitable one.

  • Patent number: 8054378
    Abstract: A webcam module having a clamping device includes a body portion, a first sliding unit, a second sliding unit, a first torsion element and a second torsion element. The first sliding unit and the second sliding unit are provided on the body portion. The first sliding unit is able to slide by means of the cooperation between the sliding block and the guiding though-groove. The torsion elements are used to generate a force for clamping an article. Via the above arrangement, a user can turn a first turning portion of the first sliding unit and a second turning portion of the second sliding unit, thereby opening a first clip and a second clip to a predetermined angle. The torsion elements allow the first clip and the second clip to be clamped at a predetermined position.
