  • Publication number: 20250062085
    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.

  • Publication number: 20250062089
    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.

  • Publication number: 20250062087
    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.

  • Patent number: 11387055
    Abstract: A control device capable of providing rotational damping through a magnetic force is provided directly at the base of an electronic product and includes a supporting member, an adjusting member, and two magnetic members. The supporting member is provided at the base. The adjusting member is rotatably provided on the supporting member. The adjusting member has a bottom portion corresponding to a switch pre-installed in the base. The adjusting member further has a head portion outside the base. The two magnetic members are provided on the supporting member and the adjusting member respectively. The two magnetic members generate a magnetic force therebetween and thereby change the rotational damping between the supporting member and the adjusting member.

  • Patent number: 11322315
    Abstract: A control device capable of providing rotational damping through an elastic force is provided directly at the base of an electronic product and includes an adjusting member and an elastic member. The adjusting member is rotatably provided at the base. The adjusting member has a bottom portion corresponding to a switch provided in the base. The adjusting member further has a head portion outside the base. The elastic member is provided between the adjusting member and the base. The elastic force of the elastic member acts between the head portion of the adjusting member and the base to change the rotational damping to which the adjusting member is subjected.
