Sound production structure for key switch

The invention discloses a sound production structure for a key switch, which comprises a base, a guide core arranged on the base, a sound production piece movably arranged between the guide core and the base, and an elastic piece of which one end is fixed on the lower surface of the guide core and the other end is fixed on the sound production piece, the lower surface of the guide core is correspondingly provided with a sound production limiting part for limiting the two sides of the sound production piece to produce sound, at least one sound production limiting groove is formed in the middle of the sound production limiting part, and the sound production piece acts on the sound production limiting groove. According to the sound production structure for the key switch, the pressing sound production effect is achieved, all the structures are tightly matched, the action is smooth, rapid, stable and accurate, the service life of the structure is long, the sound production effect is good, the sound production eff
