Abstract
A keyboard device includes a key structure, a switch circuit board, a base plate and a buffering strip. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap. A first end of the buffering strip is fixed in a first coupling structure of the keycap. A second end of the buffering strip is fixed in a second coupling structure of the keycap. The buffering strip is contacted with the stabilizer bar and filled in a gap between the stabilizer bar and the first coupling structure. Since the possibility of resulting in the collision between the stabilizer bar and the keycap is minimized, the keycap device is capable of reducing noise.
