Embodiment 1

[0047] Please refer to Figure 1 to Figure 6 , the embodiment of the present invention provides a key switch with the function of pressing and sounding, which includes a base 1 and a cover 2 arranged above the base 1. The cover 2 is combined with the base 1 to form an accommodating cavity. A guide core 3 and an elastic member 4 located below the guide core 3 are respectively arranged in the accommodating chamber, and the elastic member 4 provides elastic restoring force for pressing the guide core 3 up and down; An opening through which the upper end of the guide core 3 passes. The key switch of this embodiment also includes an elastic sound-generating component 5 arranged in the accommodating cavity and on the side of the guide core 3, and a side notch 31 is formed on the side of the guide core 3, such as Figure 4 and Figure 5 shown; as Figure 4 and Figure 6 As shown, the elastic sounding component 5 includes an upper elastic piece 51 passing through the side notch 31...

Embodiment 2

[0077]The main difference between this embodiment and Embodiment 1 is that the conduction component of the key switch of this embodiment is different from that of Embodiment 1. The conduction component of this embodiment is a magnetic conduction component 7, such as Figure 20 to Figure 22 As shown, the magnetic conduction component 7 includes a magnet 71 disposed in the positioning post 35 and a magnetic inductor 72 disposed below the magnet 71, wherein a supply magnet 71 is provided on the lower end of the positioning post 35 upwards. An upper groove 351 is embedded, and a plurality of limiting blocks 352 located at the lower end of the magnet 71 protrude inward on the inner wall of the upper groove 351 . The magnet 71 is limited by the upper groove 351 , so that the magnet 71 moves up and down with the guide core 3 moving up and down.

[0078] In this embodiment, the magnetic inductor 72 can adopt various models. Preferably, a Hall element of the A3144EUAE model can be sele...

Abstract

The invention discloses a key switch with a press sound production function. The key switch comprises a base and a cover, wherein the cover is arranged on the base, the cover and the base are combinedto form an accommodating cavity, a guide core and an elastic piece are arranged in the accommodating cavity, the elastic piece is arranged below the guide core, the key switch also comprises an elastic sound production assembly, the elastic sound production assembly is arranged in the accommodating cavity and is arranged at a side edge of the guide core, a side groove opening is formed in the side edge of the guide core, the elastic sound production assembly comprises an upper elastic piece, a first lower elastic piece and a second lower elastic piece, the upper elastic piece penetrates through the side groove opening, the first lower elastic piece is arranged on the base and is connected to one end of the upper elastic piece, and the second lower elastic piece is arranged on the base andis connected to the other end of the upper elastic piece. In the key switch provided by the invention, favorable hand feeling is achieved during the press process, the sound production function by pressing for two times is achieved, the user experience is enhanced, the whole process action is high in accuracy, the structure stability is high, and the promotion and sensitivity of a sound production effect are accurate.

Description

technical field [0001] The invention relates to a key switch, in particular to a key switch with the function of pressing and sounding. Background technique [0002] Many operations of electronic devices require the use of key switches as input means. The quality of the key switch determines the experience of the input device, which requires the key switch to have a good feel and sound. Therefore, there are sounding key switches on the market, but most of them can make a sound when the guide core is pressed down and move down, but when the guide core moves up and resets, it will not make a sound. That is, during the working cycle of the key switch's downlink and rebound, the key switch only sounds once, which cannot meet the higher requirements of the user for the sense of sound. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a key switch with the function of pressing and sounding, which has a good ...
