Background
Mechanical keyboards are a type of keyboard in which, structurally, each key of the keyboard has a separate key switch, also known in the industry as a "spindle", for controlling the closing. Because each key is provided with an independent switch, the key has strong paragraph feeling, thereby generating special hand feeling suitable for game and entertainment.
Mechanical keyboards also typically exhibit a pronounced clicking sound relative to membrane keyboards because the keys of the mechanical keyboard exhibit a pronounced clicking sensation upon being struck. The reason is that plastic rubber impact is generated when the keys of the mechanical keyboard are pressed to touch the bottom or lifted to return in the using process.
In fact, for one part of the users, the tapping sound of the mechanical keyboard brings rhythm, so that the users can have a happy experience in the using process, but for the other part of the users, the frequent tapping sound can become objectionable noise.
