Abstract: A keyboard includes a base, a key module, and a buffer unit. The base has a bottom wall and an inner periphery wall connected to the bottom wall. The key module is disposed in the base and has a printed circuit board assembly. The buffer unit is disposed in the base and includes a cantilever with a top end connected to the bottom surface of the printed circuit board assembly and a bottom end spaced from the bottom wall of the base, and a torsion spring sleeved on the cantilever and having two end portions abutted against the bottom wall of the base and the inner periphery wall of the base, respectively. Therefore, the keyboard of the present invention utilizes coordination of the cantilever and the torsion spring to provide excellent support, thus maintaining a good keypress feel while effectively eliminating noise and cushioning impact force.

Abstract: A keyboard includes a key frame, a support frame, a circuit board, a noise reduction frame, and a plurality of keys. The noise reduction frame accommodates the key frame, the support frame, and the circuit board. The keys are inserted through the key frame and the support frame and in contact with the circuit board. As such, when the keys are pressed, the noise generated by the keys are reflected in various directions by noise reduction strips provided in the noise reduction frame, thus reducing the intensity of the noise and achieving a noise reduction effect.

Abstract: A keyboard includes a key frame, a support frame, a circuit board, a buffer and noise reduction pad, and a plurality of keys. The key frame and the support frame are assembled with each other. The circuit board is mounted to the bottom surface of the support frame. The buffer and noise reduction pad is abutted against the bottom surface of the circuit board. The keys are inserted through the key frame and the support frame. As such, when the key is pressed, the vibrations and noise generated by the key are counteracted and absorbed by the buffer and noise reduction pad, thereby reducing the intensity of the vibrations and noise and achieving buffer and noise reduction effects.
