Keyboards are the most commonly used and most important input device. English letters, numbers, punctuation marks, etc. can be input into the computer through the keyboard, thereby issuing commands to the computer, inputting data, etc. According to the working principle of the keyboard, it can be divided into plastic film keyboards, conductive rubber keyboards and mechanical keyboards; structurally, each key of a mechanical keyboard has a separate switch to control the closure. This switch is also called an "axis". According to the classification of micro switches, mechanical keyboards can be divided into traditional tea axes, green axes, white axes, black axes, red axes and optical axes.

[0003] As mechanical keyboards have a strong sense of segmentation, they will cause a lot of noise during use, which is particularly unsuitable for use in office environments. Many existing keyboards simply use rubber rings to buffer and reduce noise, but the noise reduction method is very inefficient. At the same time, the sound generated by the gasket at the bottom of the keycap touching the inner wall of the key compartment cannot effectively reduce noise, thereby affecting the user's work efficiency. The noise reduction effect is relatively poor. In this regard, this solution specifically proposes a noise reduction keyboard to solve the above problem. Utility Model Content
