Patent number: 11551888Abstract: A keyswitch structure includes a base, a cap disposed corresponding to the base, a restoring member disposed between the base and the cap, and a tactile adjustment unit. The cap has a cam portion movable relative to the base. The restoring member is configured to provide a restoring force to enable the cam portion to move away from the base. The tactile adjustment unit is disposed corresponding to the cam portion and includes a holder and a tactile feedback member mounted on the holder. The holder is movable relative to the base to change a position of the tactile feedback member relative to the cam portion, so as to change a pressing force required for the cam portion to move toward the base.Type: GrantFiled: February 4, 2021Date of Patent: January 10, 2023Assignee: DARFON ELECTRONICS CORP.Inventors: Chen Yang, Chia-Hung Liu, Yu-Chun Hsieh

Publication number: 20220406539Abstract: A key structure includes a base, a movable mechanism movably positioned on the base, a sound generating member positioned on the base, and an adjusting unit movable relative to the base to be at a first position or a second position. The sound generating member has a hitting portion, which extends corresponding to an impact surface. When the adjusting unit is at the first position, and a pressing force is applied to the movable mechanism, the movable mechanism moves relative to the base and drives the sound generating member to move, so the hitting portion moves to hit the impact surface to generate a hitting sound. When the adjusting unit is at the second position, the adjusting unit restricts movement of the hitting portion, so the hitting portion cannot move to hit the impact surface.Type: ApplicationFiled: June 16, 2022Publication date: December 22, 2022Inventors: Yu-Chun HSIEH, Ling-Hsi CHAO, Shao-Lun HSIAO, Chen YANG
