Abstract

The embodiment of the invention discloses a key device. The key device comprises a terminal housing and a pressure sensing system, wherein the terminal housing comprises a pressed region, the pressed region is used for bearing a pressure and transmitting the pressure to the pressure sensing system; and the pressure sensing system comprises a fitting piece and a pressure-sensitive element arranged between the fitting piece and the pressed region, and the pressure-sensitive element senses the pressure transmitted by the pressed region and outputs a corresponding control signal. The embodiment of the invention further provides a terminal comprising the key device. According to the invention, the key device provided by the embodiment of the invention is capable of realizing a key function under the condition that the terminal housing is not open, a keycap is prevented from being clamped and worn, the dustproof and waterproof functions of the terminal are improved, and the service lifetime of the terminal is further prolonged.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a button device and a terminal. Background technique [0002] For an electronic device, an input device is an essential part, and these input devices include a keyboard (button), a mouse, a touch screen, and the like. Buttons are becoming more and more streamlined in portable mobile terminals, and are mainly used to realize functions such as switching on and off, locking the screen, and adjusting volume. [0003] At present, the keys of mobile terminals are generally composed of keycaps, flexible circuit boards with pots and electronic connectors, and related fixed parts. The user presses the keycap to trigger the dome to generate a signal, and the signal is transmitted to the main board through the flexible circuit board for related processing. [0004] However, the design of the working parts of this type of side key requires opening holes in the body of the mobile termin...
