Problems solved by technology

[0004] Since the hard body 1 in the above-mentioned keyboard is made of steel-like hard material, such a keyboard has a cold feeling and poor touch during use, thereby reducing the comprehensive use index of the entire mobile phone
In addition, in order to have a good positioning fit between the keyboard and the shell, the above-mentioned steel sheet needs to be processed and bent to form a positioning surface for positioning with the shell. This kind of bending forming process is relatively complicated. The key surface of the medium metal sheet is easily deformed, resulting in a decrease in levelness, and an additional key surface leveling process is required to ensure a good levelness of the keyboard

Abstract

The invention provides a keyboard on an electronic product, wherein the electronic product is provided with a casing and a circuit board. The keyboard comprises a first elastic body and a hard body which is positioned on the upper surface of the first elastic body, a projection on the first elastic body protrudes toward the circuit board, the casing is provided with a positioning portion, the keyboard is provided with an engaging portion engaged with the positioning portion for positioning, and the upper surface of the hard body is provided with a second elastic body. The upper surface of thekeyboard is equipped with the elastic bodies, thereby realizing excellent sense of touch of the whole keyboard.

Description

technical field [0001] The invention relates to a keyboard, in particular to a keyboard with good pressing feeling. Background technique [0002] With the continuous development of science and technology, there are more and more portable electronic products with input functions, such as mobile phones, electronic dictionaries, PDA (Personal Digital Assistant, personal digital assistant) and so on. These electronic products continue to be miniaturized and ultra-thin for easy portability. The keyboard occupies a relatively large proportion of the volume of the entire electronic product, and plays a vital role in the miniaturization of the device. The thickness of the keyboard will directly affect the thickness of the entire device. At the same time, the keyboard should also have a connection with the shell A good positioning fit. [0003] figure 1 A cross-sectional view of a keyboard in the prior art is shown. The keyboard includes an elastic body 2 and a hard body 1 locate...
