Abstract: A method for manufacturing a battery shell of an electronic device includes providing a first metal component, providing a plastic casing, joining the first metal component to the plastic casing together, providing a battery pack, the battery pack including a main body and a connection part, disposing the battery pack on the first metal component, and fixing the connection part on the plastic casing. The thickness of the first metal component is A, the thickness of the plastic casing is B. The thickness of said plastic casing satisfies 0.4 mm?B?0.8 mm, and the total thickness of the first metal component and the plastic casing satisfies 0.8 mm?A+B?1.6 mm. The connection part is disposed on a side of the main body.

Abstract: The disclosure discloses a method for manufacturing a battery shell applicable to an electronic device. The method includes providing a metal substrate, a metal implanting component including a connecting part disposed thereon; bonding the metal implanting component to the metal substrate; and forming a plastic component on the metal substrate by an insert molding process. The plastic component covers the metal implanting component. By bonding the plastic component to the bonding part of the metal implanting component, the bonding strength is enforced.

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.
