Abstract
A keypad assembly includes a keypad cover, a printed circuit board and a sensing module. The sensing module is arranged between the keypad cover and the printed circuit board. The sensing module is used to sense touches of a user's finger on the keypad cover. A portable electronic device equipped with the keypad assembly is also described.
Claims9
A keypad assembly mounted to a portable electronic device including a central processing unit and a signal outputting module electronically connected to the central processing unit, the keypad assembly comprising:
- a keypad cover;
- a printed circuit board;
- and
- a sensing module positioned between the keypad cover and the printed circuit board, the sensing module and the printed circuit board being electrically connected to the central processing unit, the sensing module sensing touches of a user's finger on the keypad cover and triggered to send out corresponding electronic signals to the central processing unit, the central processing unit transforming received electronic signals to export commands and transmitting the export commands to the signal outputting module, the signal outputting module exporting signals corresponding to the outputting commands for identifications.
