Abstract
An input device in an environment where pressure changes. The input device comprises a plate layer, a circuit layer, a keypad layer, a protection layer, and a sealed and liquid-tight space. The keypad layer is attached to the plate layer. The sealed and liquid-tight space is formed between the plate layer and the keypad layer. The circuit layer is disposed in the sealed and liquid-tight space. Furthermore, the plate layer has a first hole, and the circuit layer has a second hole corresponding to the first hole. The protection layer is attached to the plate layer and corresponds to the sealed and liquid-tight space. The air permeable rate of the protection layer is between 10% and 50% so that the inside pressure and the outside pressure of the input device can reach an equilibrium.
Claims10
An input device in an environment where pressure changes, comprising:
- a plate layer having a first hole;
- a circuit layer disposed on the plate layer, having at least one second hole corresponding to the first hole;
- a keypad layer disposed on the plate layer, covering the circuit layer;
- a protection layer attached to the plate layer, corresponding to the first hole and having a air permeable rate between 10% and 50%;
- and
- a sealed and liquid-tight space formed between the plate layer and the keypad layer for air flowing.
