Sound production structure of keyboard switch

Abstract

The invention discloses a sound production structure of a keyboard switch. The sound production structure comprises a shell and a pressing assembly movably installed in the shell, wherein the pressing assembly comprises a key cap and a pressing rod, the lower end of the key cap is provided with an accommodating groove with an opening facing downwards, the side surface of the accommodating groove is provided with an oblique groove penetrating through the inner side and the outer side of the accommodating groove, the upper end of the pressing rod is provided with a limiting rod corresponding to the oblique groove, the upper end of the pressing rod is movably installed in the accommodating groove, the limiting rod is clamped in the oblique groove, a first return element used for enabling the pressing rod to always have a downward extending trend is arranged in the accommodating groove, a through hole which is used for the pressing rod to extend downwards is formed in the shell, the lower end side surface of the pressing rod is provided with a limiting convex block, two sides of the limiting convex block are avoidance grooves, and the inner side lower end of the through hole is provided with a stop block corresponding to the limiting convex block. By adopting the sound production structure, the abrasion situation of the keyboard switch is unlikely to occur, the blockage and oxidation phenomena are unlikely to occur, a stable working state can be maintained, and the produced sound is clear.

Description

technical field [0001] The invention relates to the technical field of keyboard keys, in particular to a sounding structure of a keyboard switch. Background technique [0002] The keyboard key is a switch applied and installed on the keyboard. Its main structure includes a shell, a pressing piece, a pressing bar, a static contact piece, a moving contact piece, etc. It mainly acts on the power contact piece by moving the pressing piece up and down, so that the moving piece The contact piece and the static contact piece are contacted and connected or separated to realize the button function. The crisp percussion sound during the use of the keyboard can often bring a wonderful user experience. The existing sound mainly comes from the activity of the metal shrapnel located in the keyboard switch, and the sound is produced through the impact of the metal shrapnel and the plastic. However, The metal shrapnel is prone to oxidation and dust accumulation as the use time increases, w...

The crisp percussion sound during the use of the keyboard can often bring a wonderful user experience. The existing sound mainly comes from the activity of the metal shrapnel located in the keyboard switch, and the sound is produced through the impact of the metal shrapnel and the plastic. However, The metal shrapnel is prone to oxidation and dust accumulation as the use time increases, which leads to the failure of the metal shrapnel activity and the sound effect.
