Abstract: A head mounted device for a helmet includes a connection module, a flexible bracket, a power supply seat and a function module. While the flexible bracket is moved relative to the connection module, a position of the power supply seat relative to the helmet is adjusted. While the function module is moved relative to the power supply seat, an orientation of the function unit is adjusted.

Abstract: The present invention provides a keyboard device, including a plurality of keys, thin film circuit boards, and key bottom plates. A connection component of the key is connected between a keycap of the key and a bottom plate connection portion of key bottom plate, and the bottom plate connection portion has a connection portion surface corresponding to the keycap and a raised portion formed on the connection portion surface. When the keycap moves downward relative to the thin film circuit board, a lower surface of the keycap knocks the raised portion.

Abstract: A touchpad module includes a touch member, a bracket, a piezoelectric vibration unit and an elastic element. The bracket is located under the touch member. A portion of the touch member is exposed to a first perforation of the bracket. The piezoelectric vibration unit is aligned with the first perforation of the bracket. The piezoelectric vibration unit has a first surface and a second surface, which are opposed to each other. The elastic element installed on the bracket and contacted with the second surface of the piezoelectric vibration unit. When the piezoelectric vibration unit vibrates, a first reaction force is generated between the first surface of the piezoelectric vibration unit and the portion of the touch member exposed to the first perforation, and a second reaction force is generated between the second surface of the piezoelectric vibration unit and the elastic element.

Abstract: A touchpad module includes a touch member, a bracket, an elastic element and a spacer. The bracket is located under the touch member. The elastic element is arranged between the touch member and the bracket. The spacer is arranged between the elastic element and the touch member. While the touch member is pressed down, the touch member is moved downwardly to compress the spacer and the elastic element is pushed by the at least one spacer. Consequently, the elastic element is subjected to deformation and extended toward the corresponding perforation. The present invention further provides a computing device with the touchpad module.

Abstract: A key structure includes a supporting plate, a triggering switch, a keycap and a soft element. The triggering switch is located over the supporting plate. The keycap is located over the triggering switch. When an external force is received by the keycap, the triggering switch is pushed by the keycap. The soft element is disposed on an inner surface of the keycap. When the soft element is contacted with the triggering switch, the soft element is subjected to deformation. When the soft element is contacted with the triggering switch, a portion of the triggering switch is inserted into the deformed soft element to limit a sliding action of the triggering switch. Consequently, the mechanical key switch provides enhanced tactile feel.
