Problems solved by technology

[0002] At present, the key switches on the market are classified according to sound and silence, and can be divided into sound key switches and silent key switches. Sound key switches can allow users to obtain better feel and sound. It is relatively noisy; the silent key switch will not make a sound, which can meet the needs of some users for silent pressing, but the silent key switch has a poor feel
However, the existing key switch can only realize the function of sound or silence, and cannot freely switch between sound and silence according to the user's needs, which brings inconvenience to the use of the user.

Embodiment 1

[0060] Please refer to Figure 1 to Figure 5 , the present embodiment provides a key switch switchable between sound and sound, including a housing 1 , the housing 1 is mainly composed of a base 11 and an upper cover 12 disposed on the base 11 . The key switch of this embodiment also includes a guide core 2 arranged on the base 11, a switching member 3 that drives the guide core 2 to rotate and extends to the outside of the casing 1, and a sound-emitting shrapnel 4 respectively arranged on the side of the guide core 2. With a silent shrapnel 5, wherein, the middle part of the sounding shrapnel 4 and the middle part of the silent shrapnel 5 all arch upwards to form an upper arch (41, 51), as Figure 10 As shown, the arched height of the upper arched portion 41 of the sound-generating shrapnel 4 is greater than the arched height of the upper arched portion 51 of the silent shrapnel 5 . Specifically, the arched height of the upper arched portion 41 of the sound-generating shrapn...

Embodiment 2

[0090] Such as Figure 12 and Figure 13 As shown, the main difference between the present embodiment and the first embodiment is that the switching member 3 is a toggle block 32 connected to the side of the guide core 2 . At the same time, a strip-shaped toggle opening 13 is opened on the side of the housing 1 for the toggle block 32 to pass through.

[0091] By manipulating the toggle block 32, the toggle block 32 moves in the bar-shaped toggle opening 13, which can drive the guide core 2 to rotate a certain angle, such as 30°, 60° or 90°, etc., so as to realize the function The change of the position of the arm 6 realizes the free switching between pressing with sound and without sound, thus obtaining two different pressing effects.

Embodiment 3

[0093] The main difference between this embodiment and Embodiment 1 or Embodiment 2 is that: the switching member 3 is a push member.

[0094] The specific structure design is as follows:

[0095] Such as Figure 14 to Figure 18 As shown, a guide groove seat 114 is provided on the base 11, and a central groove 1140 is provided in the guide groove seat 114; A button 33, a rotating shaft 20 positioned above the button 33 is provided on the guide groove seat 114, a post 201 is arranged on the top of the rotating shaft 20, and a first post for inserting the post 201 is formed upwardly at the lower end of the guide core 2. The second guide hole 22 is guided by the inserting post 201 during the up and down movement of the guide core 2, so that the guide core 2 always moves vertically, thereby improving the movement stability and action accuracy of the guide core 2. At the same time, a second return spring 30 located in the second guide hole 22 is sheathed on the periphery of the p...

Abstract

The invention discloses a key switch capable of switching sound and silent states; a shell is included; the shell is mainly composed of a base and an upper cover arranged on the base. The key switch also has a guide core arranged on the base, a switching piece that drives the guide core to rotate and extends out of the shell, and a sounding elastic piece and the a silent elastic piece that are arranged on the side edges of the guide core respectively; the middle part of the sounding elastic piece and the middle part of the silent elastic piece are both arched upwards to form an upper arch part, and the arched height of the upper arch part of the sounding elastic piece is greater than that of the upper arch part of the silent elastic piece; and at least one acting arm acting on the upper arch part is arranged on the side edge of the guide core. According to the key switch capable of switching between the sound state and the silent state, free switching between the sounding effect and the silent pressing effect can be achieved, a user can freely and flexibly switch between the sound state and the silent state according to the use requirement of the user, operation is convenient and fast, the flexibility of the product is high, different use requirements of the user are met, and great convenience is brought to use of the user.

Description

technical field [0001] The invention relates to the field of key switches, in particular to a key switch capable of switching between sound and sound. Background technique [0002] At present, the key switches on the market are classified according to sound and silence, and can be divided into sound key switches and silent key switches. Sound key switches can allow users to obtain better feel and sound. It is relatively noisy; the silent key switch does not emit sound, which can meet the needs of some users for silent pressing, but the feel of the silent key switch is poor. And the existing key switch can only realize the sound or silent function, can not freely switch between sound and silence according to the user's needs, which brings inconvenience to the use of the user. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a key switch switchable between sound and sound, which can realize the free swi...
