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.

Touchpad module and computing device using same

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.

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.
