摘要： A keyboard device includes a substrate, a keycap, a first connection member, and a first elastic arm structure. The substrate has a top surface, and the top surface has an assembling region. The keycap is disposed above the assembling region, and the keycap has a bottom surface facing the assembling region. The first connection member is connected between the keycap and the assembling region, the first connection member includes a first assembly side and a second assembly side opposite to the first assembly side, the first assembly side is pivotally connected to the bottom surface of the keycap, and the second assembly side is pivotally connected to the substrate. The first elastic arm structure includes a connection end and a free end opposite to the connection end, the connection end is connected to the first assembly side, and the free end abuts against the bottom surface of the keycap.

摘要： A key includes a substrate, a keycap, a connection component, and protruding structures. The connection component includes a first connection member and a second connection member, and the first connection member and the second connection member are between the substrate and the keycap. The protruding structures are disposed on the upper surface of the first connection member and disposed on the upper surface of the second connection member. When the keycap is pressed to a pressed position, the protruding structures on the first connection member and on the second connection member abut against the bottom surface of the keycap, so that a gap is formed between the keycap and the connection component. Therefore, the bottom surface of the keycap does not contact the upper surface of the first connection member and the upper surface of the second connection member so as to prevent from generating keystroke noises.

摘要： A keyboard includes a base plate, a keycap, and at least one balance assembly. The base plate has a plurality of connecting structures. The keycap is above the base plate. The balance assembly includes a balance bar and two silencing members. The balance bar is between the base plate and the keycap and is engaged with the keycap. The silencing members are connected to the balance bar and engaged with the connecting structures. The balance assembly is configured to guide the keycap to move relative to the base plate. Hardnesses of the base plate and the balance bar are greater than a hardness of the silencing members.
