Embodiment 1

[0040] 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

[0057] 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 15 to Figure 17 As shown, the magnetic conduction component 7 includes a magnet 71 disposed in the positioning post 35 and a magnetic inductor 722 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.

[0058] In this embodiment, the magnetic sensor 72 can be arranged on the PCB board, and usually the base 1 is arranged on the upper end s...

Abstract

The invention discloses a key switch with the function of pressing and producing sound, including a base, and a cover arranged above the base, The cover and the base are combined to form a receiving cavity, A lead core and an elastic member positioned below the guide core are arranged in the contain cavity, and an elastic sounding assembly arranged in the accommodating cavity and located at the side of the guide core is included. At the side edge of the guide core, a side notch is formed, and the elastic sounding assembly includes an upper spring piece passing through the side notch, a firstlower spring piece arranged on the base and connected to one end of the upper spring piece, and a second lower spring piece arranged on the base and connected to the other end of the upper spring piece. The key switch provided by the invention has a good hand feeling in the pressing process, realizes the pressing and sounding function, improves the user experience, and has the advantages of high action accuracy in the whole process, high structural stability, and sensitive and accurate stimulation of the sounding effect.

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. Due to the limitation of the internal space of the switch, the existing thin key switch has a relatively insufficient design of the sounding structure and lacks a pressing feel, so it still cannot have a pressing sound like a large key switch. 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 feel during the pressing process, and realizes the function of pressing and sounding to improve user experience. The whole process has high action accuracy an...
