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.

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 pico projection fixing module includes a bracket main body, at least two collimator lenses, and at least two color light sources. The bracket main body includes an upper part, a lower part, a connecting part and at least two assembling seats. The upper part and the lower part are located at bilateral sides of the connecting part. Each of the assembling seats includes an opening and a clamping part. The opening is formed on the connecting part. The clamping part is disposed on the upper part and the lower part. The at least two collimator lenses are installed on the connecting part and corresponded to the corresponding openings. The at least two color light sources are installed on the corresponding clamping parts and aligned with the corresponding collimator lenses. The clamping parts corresponding to the assembling seats are separated from each other.

Abstract: A pico projection fixing module includes a bracket main body, plural color light sources, and plural collimator lenses. The bracket main body includes plural assembling seats. The plural assembling seats are arranged side by side. Each of the plural assembling seats includes a first assembling part and a second assembling part beside the corresponding first assembling part. The plural color light sources are installed on the first assembling parts of the plural assembling seats, respectively. The plural collimator lenses are installed on the second assembling parts of the plural assembling seats and aligned with the plural color light sources, respectively. Moreover, plural color light beams from the plural color light sources are projected out through the corresponding collimator lenses. Moreover, plural concave spaces are arranged around bottoms of the plural second assembling parts, respectively, wherein the plural concave spaces are separated from each other.
