Abstract:
A sound-production key switch, comprising a base (1) and a guide core (2) provided on the base. At least one pressing bump (21) is provided on the guide core; a sound-production assembly (3) located on the side edge of the pressing bump is provided on the base; the sound-production assembly comprises a rotating push rod (31) rotatably provided on the base, and a metal dome (32) provided on the base and located on the side edge of the rotating push rod; and the rotating push rod comprises a rotating shaft (311) rotatably provided on the base, at least one push block (312) provided on the rotating shaft and corresponding to the pressing bump, and a knocking arm (313) provided on the rotating shaft and facing the metal dome. The sound-production key switch can realize a function of pressing to produce sound, and is accurate in an action of knocking to produce sound, clear in sound, and good in sound production effect. Meanwhile, the action of knocking to produce sound and a turn-on action occur at the same time, such that the effect of synchronization of turning on at the upper portion and producing sound at the lower portion is achieved, thereby implementing the function of pressing to produce sound while achieving the turn-on and turn-off functions of the key switch.
