  • Publication number: 20230152043
    Abstract: A vapor chamber structure includes an upper plate, a lower plate, a middle layer and a polymer layer. The polymer layer is selectively connected with any of the upper and lower plates. The lower plate and the upper plate are mated with each other to together define a chamber. A working fluid is filled in the chamber. The middle layer is disposed in the chamber. The middle layer has a first face, a second face, multiple perforations and multiple channels. The multiple perforations pass through the first and second faces. The multiple channels are disposed on one of the first and second faces. By means of the above arrangement, the total thickness of the vapor chamber structure is equal to or smaller than 0.25 mm, whereby the vapor chamber can be extremely thinned.

  • Publication number: 20230129863
    Abstract: A sensing keyswitch including a key body, a key-sensing switch and an enabling switch is provided. The key body includes a key top, and a key driver and an enabler which can move with the key top in the same keystroke cycle. The key-sensing switch electrically connected to a key circuit is in a disabled mode to save power and cannot sense the change of the sensing intensity caused by the movement of the driver. The enabling switch is electrically connected to an enabling circuit, wherein when the enabling switch is triggered by the enabler, the enabling switch outputs an enabling signal through the enabling circuit for enabling the key-sensing switch to enter an enabled mode, so that the key-sensing switch can sense the change of the sensing intensity caused by the movement of the key driver to trigger a key signal.

  • Publication number: 20220406539
    Abstract: A key structure includes a base, a movable mechanism movably positioned on the base, a sound generating member positioned on the base, and an adjusting unit movable relative to the base to be at a first position or a second position. The sound generating member has a hitting portion, which extends corresponding to an impact surface. When the adjusting unit is at the first position, and a pressing force is applied to the movable mechanism, the movable mechanism moves relative to the base and drives the sound generating member to move, so the hitting portion moves to hit the impact surface to generate a hitting sound. When the adjusting unit is at the second position, the adjusting unit restricts movement of the hitting portion, so the hitting portion cannot move to hit the impact surface.
