Abstract
A key structure includes a base plate, a supporting element, a resilience arm and a keycap. The keycap includes a bulge. The supporting element is installed on the base plate. The resilience arm is connected with the supporting element and aligned with the bulge of the keycap. The keycap is connected with the supporting element. When the keycap is moved toward the base plate, the bulge is moved downwardly to push the resilience arm. After the resilience arm is pushed by the bulge, the resilience arm is subjected to elastic deformation and separated from the bulge. After the resilience arm is separated from the bulge, the resilience arm knocks on the keycap, so that a sound is generated.
Claims9
A key structure, comprising:
- a base plate;
- a circuit layer installed on the base plate;
- an elastic element installed on the circuit layer;
- a supporting element installed on the base plate, wherein the elastic element is enclosed by the supporting element;
- a resilience arm connected with the supporting element;
- and
- a keycap covering the elastic element, wherein the keycap is connected with the supporting element, and the keycap comprises a bulge corresponding to the resilience arm,
- wherein when the keycap is moved toward the base plate, the bulge is moved downwardly to push the resilience arm, wherein after the resilience arm is pushed by the bulge, the resilience arm is subjected to elastic deformation and separated from the bulge, wherein after the resilience arm is separated from the bulge, the resilience arm knocks on the keycap, so that a sound is generated.
