Keyboard device
A keyboard device includes a key structure and a membrane circuit board. The membrane circuit board includes a membrane switch. The membrane switch is located under the key structure. The key structure includes a pedestal structure, a covering structure, a keycap, a connecting element, a dome-type elastomer and a knocking element. The keycap is installed on the covering structure. The connecting element is connected between the covering structure and the pedestal structure. The dome-type elastomer is arranged between the covering structure and the membrane circuit board. When the keycap is not depressed, the knocking element is supported on the connecting element. While the keycap is depressed, the knocking element knocks on the connecting element to generate an operating sound and provide the operating feedback to the user.
