Abstract
A key structure includes a connecting plate, a keycap, a triggering element, a scissors-type connecting element, a membrane switch circuit member, and a supporting plate. The keycap includes a protrusion part. The supporting plate includes an accommodation part and an elastic structure. The elastic structure is aligned with the protrusion part and disposed within the accommodation part. When the keycap is depressed, the protrusion part is moved with the keycap to push the triggering element. Consequently, the membrane switch circuit member is triggered by the triggering element. Moreover, as the protrusion part is moved with the keycap, the protrusion part collides with the elastic structure to generate a sound.
