Abstract: Disclosed is a waterproof key module, including: a housing with a hollow inner chamber and an opening at an end, comprising a front housing portion and a bottom housing portion secured to each other, and the opening being provided on the front housing portion; a touch component limited in the inner chamber, comprising a touch plate extending out from the opening; and a waterproof adhesive film in a pre-tensioned status and isolating the touch component from the bottom housing portion, an edge of the film being secured to a position where the front housing portion is connected to the bottom housing portion, and the touch component being supported on the film; wherein at least one pressure sensor module is provided between the touch component and the bottom housing portion and configured to generate a pressure signal that represents a pressure degree according to a pressing on the touch component.

Abstract: A waterproof keypad module, comprising a waterproof film (7) which is in a pre-tightened state and which isolates a touch component from a bottom casing (4); an edge of said waterproof film being fixed at the position where a front casing (1) and the bottom casing (4) connect, and said touch component being supported on said waterproof film (7). The edge of said waterproof film is fixed at the position where the front casing (1) and bottom casing (4) connect, wherein the touch component may be completely isolated from the bottom casing (4) by means of the waterproof film (7); thus, even if a gap exists between the touch component and casing, water cannot pass through the waterproof film (7) and enter the bottom casing (4), thus achieving waterproofing of the keypad module.

Abstract: A touch control system and electronic device, said touch control system comprising a touch control element (110), a touch control sensor apparatus (120), an analog-to-digital converter unit (130), a digital signal processing unit (140), and a function regulating unit (150), wherein said touch control sensor apparatus (120) is provided with a first pressure sensor (10) and a second pressure sensor (20). Said touch control sensor apparatus (120) is configured to convert swiping actions of a user on the touch control element (110) into an analog voltage signal, said analog-to-digital converter unit (130) is configured to convert the analog voltage signal into a digital signal; said digital signal processing unit (140) is configured to calculate swiping pressure information and position information on the basis of the digital signal, said function regulating unit (150) regulates corresponding functions on the basis of the swiping pressure information and position information.

Abstract: A touch pressure control method and device are provided. The touch pressure control method comprises: determining, according to a first pressure value and a second pressure value generated in response to a single touch operation, a pressure level and a touch point position corresponding to the touch operation; and selecting, according to the pressure level and the touch point position, a corresponding function or application from a function and application list, and controlling an implementation of the function or application.
