Embodiment Construction
[0033] refer to figure 2 A schematic diagram of a side key device according to an embodiment of the present invention. Embodiments of the present invention are described by taking the device applied to mobile communication equipment such as mobile phones as an example, but not limited thereto. Such as figure 2 shown, including:
[0034] Case 11, side key 12, shrapnel Dome13, FPC14, bracket reinforcement 15, PCB16, LCD 18.
[0035] The casing 11 is an exterior part of the mobile phone and is used to protect internal parts. The side key 12 is a moving part, which triggers the Dome 13 after the force movement reaches a certain stroke. Dome 13 will deform after being stressed, triggering a hardware signal. FPC14, as a flexible circuit board, transmits hardware signals. One side of the FPC 14 is connected to the elastic dome 13 to receive the force of the side key, and the other side is connected to the bracket reinforcement 15 . The bracket reinforcement 15 is used as a s...
