  • Keyswitch, keyboard and related force feedback method
    Patent number: 9373464
    Abstract: A keyswitch with force feedback function includes a vibrating source, a switching circuit and a controller. The vibrating source is connected to a cap of the keyswitch. The switching circuit is switched on according to states of the keyswitch. The controller is electrically connected to the vibrating source and the switching circuit. When the switching circuit is switched on, the controller outputs a first driving signal to the vibrating source, and the vibrating source transmits a pressing vibration to the cap of the keyswitch. A period of the first driving signal is smaller than or equal to a predetermined period, a user can feel vibration of the keyswitch due to the pressing vibration.

  • KEYBOARD HAVING TACTILE FEEDBACK
    Publication number: 20150034471
    Abstract: A keyboard capable of generating a tactile feedback signal makes use of acceleration change of pressing behavior and releasing behavior of a physical keyswitch during pressing and releasing stages. The acceleration change is modulated according to a touch sensitive frequency response in various ways so that a simulated tactile feedback may be generated on the keyswitches of the keyboard.
