New Description: [New Technology Field] This creation is about the technical field of a button and keyboard, especially a low-noise button and keyboard that are easy to manufacture and low in cost. η [Prior Art] With the development of information technology, computers are almost one of the indispensable tools for modern people's work, entertainment and even communication. The most important human-machine interface between the person and the computer for inputting commands and operating the computer is the keyboard and mouse. As the needs of users continue to change, keyboards of various functions are developed one by one, such as folding keyboards, membrane keyboards, waterproof keyboards, and even illuminated keyboards. Some types of keyboards need to be provided with an upper cover in the keyboard for functional requirements, so that each button is set in the accommodating space formed between the base plate and the upper cover of the keyboard. For example, in the patent patent No. 351402, the "key and keyboard" novel patent, the main φ discloses a button and a keyboard, the keyboard includes a substrate, an upper cover and a plurality of - buttons, the upper cover is disposed on the substrate and has a plurality of accommodation spaces, and Each button is respectively disposed in one of the accommodating spaces, each button includes a key cap and a lifting support device, and the lifting support device enables the key cap to move up and down with respect to the base plate along with the lifting support device, and the key cap has a skirt. The skirt is in contact with the upper cover, wherein the upper cover, the keycap and the skirt form a complete surface, thereby preventing light from escaping and keeping the key height uniform. It is further disclosed in the patent that in order to avoid unnecessary noise caused by the collision of the skirt of the button with the upper cover, a soft member can be loaded on the upper surface of the skirt, and the 3 M381115 allows the skirt to be cushioned by the characteristics of a soft material such as rubber. Collision with the upper cover and reduce the noise generated during contact, which improves the comfort of the operating keyboard. The patent further discloses that the soft member is formed by a secondary injection molding process or a surface painting process. However, in practice, the button with the soft member is made through the secondary injection molding process, and the production cost is high. In the case of a button having a soft member made by a painting process, the thickness of the soft member is thin, the cushioning effect is low, and it may not be economical. Therefore, the foregoing techniques are still necessary to be improved in order to solve the existing problems. [New content] In view of this, the main purpose of this creation is to solve the above problems and provide a low-noise button and keyboard that are easy to manufacture and low in cost. In order to achieve the above purpose, the low noise button of the present invention is applied to a keyboard, which is composed of a substrate, an upper cover and a plurality of buttons, and each button is respectively disposed in a plurality of accommodating spaces of the upper cover. Each button is composed of a key cap and a buffering member, wherein the key cap is movable up and down with respect to the substrate, and a plurality of protrusions are protruded from the periphery of the keycap and are at the periphery of the keycap The buffering member is sleeved, and the buffering member has a perforation corresponding to each of the protruding posts, so that the protruding posts pass through the respective perforations and are combined with the buffering member. Thereby, each of the buffer member and the keycap can be separately manufactured and combined, and the effect of being easy to manufacture and reducing the cost can be achieved, and each button is touched by the cushioning member and the upper cover, thereby reducing noise. Preferably, the keycap is made of a thermoplastic material and the posts are bonded to the cushioning member by means of hot melt compression. M381115 Preferably, the periphery of the keycap extends horizontally with a cap edge, and each of the studs protrudes upward from the cap edge, and the buffer member is disposed on the top surface of the cap. Preferably, the surface of the buffer member has a convex lip which is convex upward, and each of the protrusions is combined with the buffer member to have a height higher than the height of each of the protrusions. Preferably, each of the protruding pillars protrudes downwardly from the keycap, and the bottom surface of the cushioning member has a concave portion, so that the convex pillars are combined with the buffering member, and are accommodated in the concave portion, and The support of the cushioning member. Preferably, the cushioning member is made of a soft material such as a rubber material. Preferably, the cushion member is in contact with the upper cover when the button is in a non-pressed state.
