[0015] 1A and 1B are schematic cross-sectional views of a keyboard according to a first embodiment of the present invention. Please refer to FIG. 1A and FIG. 1B at the same time. The keyboard 100a can be a portable keyboard, or can be applied to a portable electronic device, such as a mobile phone, a personal digital assistant, a notebook computer or a super mobile computer. The keyboard 100a includes at least one key 110 having a first height adjustment member 112 and a second height adjustment member 120 disposed below the key 110 . In order to simplify the drawings, FIG. 1A and FIG. 1B only schematically show two buttons 110, but here it is emphasized that the keyboard 100a may include multiple buttons 110, so the number of buttons 110 shown in FIG. 1A and FIG. 1B is only for illustration. , not limiting the present invention.

[0016] In this embodiment, each button 110 may have a receiving groove 114 , and each first height adjusting member 112 is disposed in the corresp...

[0024] 2A and 2B are schematic cross-sectional views of a keyboard according to a second embodiment of the present invention. Please refer to FIG. 2A and FIG. 2B at the same time. The main difference between the keyboard 100b of this embodiment and the previous embodiment is that the second height adjustment member 120' of the keyboard 100b can have variable magnetic properties, that is, the second height adjustment member 120' can be electromagnetic. Iron (electromagnet). Therefore, the second height adjusting member 120' may have an inductive coil and a magnetic core wound by the inductive coil, and the material of the magnetic core may be ferromagnetic material or ferrimagnetic material. Material (ferrimagnetic material).

[0025] 2A is a schematic cross-sectional view of the keyboard 100b when each first height adjustment member 112 and the second height adjustment member 120' attract each other, and FIG. 2B is a schematic cross-sectional view of the keyboard 100b when ea...

Abstract

The invention discloses a keyboard, comprising at least a keystoke with a first height adjusting piece and a second height adjusting piece. The second height adjusting piece is arranged below the keystoke. A variable magnetic force is existed between the first height adjusting piece and the second height adjusting piece. When the first height adjusting piece and the second height adjusting piece mutually attract, the keystroke maintains a first height relative to the second height adjusting piece. When the first height adjusting piece and the second height adjusting piece mutually exclude, the keystroke maintains a second height relative to the second height adjusting piece. The second height is more than the first height. So, the overall volume of the keystoke is adjusted to reduce.

Description

technical field [0001] The present invention relates to a keyboard, and in particular to a keyboard with adjustable key heights. Background technique [0002] Today's portable electronic devices, such as personal digital assistants (personal digital assistants, PDAs), mobile phones, notebook computers (notebooks) and ultra mobile personalcomputers (ultra mobile personalcomputers (UMPCs), have brought convenience to modern people's lives, and gradually become an indispensable tool. [0003] Currently, users usually use keyboards to operate portable electronic devices. In order to enable the user to feel a better touch when using the keyboard, there is an active space between the keys of the keyboard and the internal circuit board for these keys to move. When certain keys are pressed, these keys will move in the activity space, and the user can feel the movement of these keys through fingers to confirm whether these keys are pressed. Therefore, the user can feel a better to...
