[0029] Please refer to Figures 1 to 4 , for a silent button 100 of an embodiment of the utility model, which includes a cover plate 10, a bottom plate 20, a fastener 30 and an elastic member 40. The cover plate 10 covers the bottom plate 20, and the cover plate 10 is made of soft rubber material; the cover plate 10 includes a substrate portion 11, a panel portion 12 and a connecting portion 13, and the connecting portion 13 is arranged along the periphery of the panel portion 12; one end of the connecting portion 13 is connected to the substrate portion 11, and the other end is connected to the panel portion 12. The connecting portion 13 is inclined outward from one end connecting the panel portion 12 towards the end connecting the substrate portion 11; one end of the fastener 30 is installed on the panel portion 12, and the other end passes through the bottom plate 20; the elastic member 40 is sleeved on the fastener 30, one end of the elastic member 40 abuts against the panel portion 12, and the other end abuts against the bottom plate 20. In this silent button 100, the connecting portion 13 is inclined outward from one end connecting the panel portion 12 towards the end connecting the substrate portion 11 to provide a space for the panel portion 12 to slide down; by sleeving the elastic member 40 on the fastener 30, with one end of the elastic member 40 abutting against the panel portion 12 and the other end abutting against the bottom plate 20, when the panel portion 12 is pressed, it plays a buffering role and reduces the noise generated by pressing; by using a soft rubber material for the cover plate 10, the pressing noise is reduced.

[0030] As Figures 1 to 4As shown in the figure, in this embodiment, the cover plate 10 is covered on the bottom plate 20. The cover plate 10 is made of soft rubber material to reduce pressing noise. Optionally, the cover plate 10 is made of rubber material. The cover plate 10 includes a base plate portion 11, a panel portion 12 and a connecting portion 13. The connecting portion 13 is arranged along the perimeter of the panel portion 12. One end of the connecting portion 13 is connected to the base plate portion 11, and the other end is connected to the panel portion 12. The connecting portion 13 is inclined outward from the end connecting the panel portion 12 towards the end connecting the base plate portion 11 to provide space for the panel portion 12 to slide down. Moreover, since the cover plate 10 is made of soft rubber material, when the panel portion 12 is pressed down, the connecting portion 13 undergoes elastic deformation. Optionally, the base plate portion 11 is provided with a plurality of slots 111. Further, the bottom of the base plate portion 11 is provided with a plurality of positioning grooves 112. One side of the base plate portion 11 is provided with a anti-misassembly hole 113. In one embodiment, the panel portion 12 is provided with a groove 121. A relief groove 122 is provided on the side of the panel portion 12 connected to the base plate portion 11. By providing the relief groove 122, the height of the connection between the connecting portion 13 and the panel portion 12 is increased, thereby extending the length of the connecting portion 13 to ensure that when the panel portion 12 is pressed down, the connecting portion 13 can undergo sufficient deformation. In one embodiment, the cover plate 10 further includes a plurality of reinforcing portions 14. The reinforcing portions 14 protrude from the bottom of the panel portion 12 to provide sufficient supporting force. Additionally, when the reinforcing portions 14 abut against the bottom plate 20, they can also play a limiting role.

[0031] As Figures 1 to 3 shown in the figure, the bottom plate 20 is provided with a through hole 201. The bottom plate 20 includes a plurality of limiting posts 21. The slots 111 are used to accommodate the limiting posts 21 to fix the cover plate 10. Each limiting post 21 is arranged in one-to-one correspondence with the slots 111. Optionally, the bottom plate 20 further includes a plurality of protruding posts 22. The positioning grooves 112 are used to accommodate the protruding posts 22 to further limit the position of the cover plate 10. Each positioning groove 112 is arranged in one-to-one correspondence with the protruding posts 22. Further, the bottom plate 20 further includes a guiding block 23. The anti-misassembly hole 113 is used to accommodate the guiding block 23 to facilitate the installation of the cover plate 10.

[0032] As Figure 3 shown in the figure, one end of the fastener 30 is installed on the panel portion 12, and the other end passes through the bottom plate 20. One end of the fastener 30 is received in the through hole 201. Optionally, the fastener 30 is arranged in an inverted "T" shape.

[0033] As Figure 2 shown in Figure 3 the figure, the elastic member 40 is sleeved on the fastener 30. One end of the elastic member 40 abuts against the panel portion 12, and the other end abuts against the bottom plate 20. Optionally, the groove 121 is used to accommodate the elastic member 40 and the fastener 30. Further, both the fastener 30 and the elastic member 40 are two and are arranged in one-to-one correspondence. The two fasteners 30 are installed on the panel portion 12 at intervals. In one embodiment, the elastic member 40 is a spring.

[0034] When the cover plate 10 is pressed down, the panel part 12 compresses the elastic member 40, the fastener 30 slides on the bottom plate 20, and the connecting part 13 undergoes elastic deformation, playing a buffering role and reducing the noise generated by pressing; after the pressing is completed and the cover plate 10 is released, under the action of the elastic member 40, the fastener 30 slides on the bottom plate 20 and the connecting part 13 returns to its original position.

[0035] In the mute button 100 of the present utility model, the connecting part 13 is inclined outward from one end connecting the panel part 12 towards one end connecting the substrate part 11 to provide a space for the panel part 12 to slide down; the elastic member 40 is sleeved on the fastener 30, one end of the elastic member 40 abuts against the panel part 12, and the other end abuts against the bottom plate 20, playing a buffering role when the panel part 12 is pressed and reducing the noise generated by pressing; the cover plate 10 is made of soft rubber material to reduce the pressing noise; the mute button 100 has a simple structure and good mute effect.

[0036] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0037] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
