Abstract
A keyboard device includes a key structure, a switch circuit board, a base plate, a soft covering element and a buffering pad. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap and the soft covering element. The soft covering element is disposed on the base plate. An accommodation space is defined by the soft covering element and the base plate collaboratively. The stabilizer bar is inserted into the accommodation space, so that the stabilizer bar is connected with the base plate. The buffering pad is disposed on the base plate and partially received within the accommodation space. The stabilizer bar and the base plate are made of metallic material. Since the stabilizer bar and the base plate are separated by the soft covering element and the buffering pad, the keyboard device is capable of reducing noise.
