Abstract

The invention discloses a key module and a terminal. The key module comprises an insulating medium layer, a piezoresistive flexible part arranged on the insulating medium layer, a first electrode anda second electrode, wherein the piezoresistive flexible part is arranged between the first electrode and the second electrode; the first electrode is connected with the piezoresistive flexible part; and the second electrode is connected with the piezoresistive flexible part. The piezoresistive flexible part outputs different voltage signals when being pressed and not pressed respectively; a processor of the terminal can execute corresponding processing according to the different voltage signals; and a physical key form is replaced with the piezoresistive flexible part, and key holes are not required to be formed in the terminal, so that the waterproof performance and the anti-static release performance can be improved, and the appearance integrity of the whole machine can be ensured.

Description

technical field [0001] The invention relates to the field of terminal button module design, in particular to a button module and a terminal. Background technique [0002] Buttons are one of the basic configurations of the terminal, such as volume buttons, power buttons, virtual buttons, etc. The buttons realize the corresponding functions by pressing the button panel, such as: volume increase and decrease functions, screen off function, screen bright function, etc. At present, the button of the terminal generally adopts a tact switch, and its principle is to use a metal shrapnel button to complete the switch between the on-state and the off-state of the switch. like figure 1 As shown, when the tact switch 110 is pressed, its shrapnel is deformed by the elastic force and contacts the soldering piece 120 downward, so that the two sets of pins 130 of the switch are conducted, and the circuit is in a conducting state. When the external force is removed, the shrapnel recovers ...
