As shown in fig. 1-10, the present invention provides an ultra-thin sound switch to generate sound when pressed, and the whole structure is shown in fig. 1. The ultrathin sounding switch comprises a base 1 and an elastic sheet 2, and further comprises a button 4, an upper cover 3, a balance rod 6 and a spring 7, as shown in fig. 2. Wherein, base 1 and upper cover 3 can lock each other and realize spacing to button 4, and button 4 can only reciprocate along its axis direction within a certain limit this moment. In the process, the button 4 can control the on-off of the switch through the matching of the shading sleeve 43 and the corresponding equipment, and meanwhile, the elastic sheet 2 is pressed up and down to make the elastic sheet impact to generate sound.

Specifically, the upper surface of the base 1 is recessed downward to form a receiving groove 11, the receiving groove 11 is disposed toward a side edge of the base 1 and can extend along a length direction of the side edge, and the receiving groove 11 is a strip-shaped structure. The elastic sheet 2 is located in the accommodating groove 11 and can be deformed under the extrusion action of the button 4 and move up and down relative to the accommodating groove 11. Besides the elastic sheet 2 is placed in the accommodating groove 11, a barb 111 is fixedly arranged, the barb 111 extends upwards to the position of the elastic sheet 2 along the upper surface of the accommodating groove 11, and the barb 111 can be impacted to generate sound when the elastic sheet 2 moves upwards relative to the accommodating groove 11, as shown in fig. 3-5.

When utilizing this switch to press, shell fragment 2 can be because of the characteristics that external force drove and reciprocate for holding tank 11, and barb 111 structure is installed in the design in holding tank 11, can strike the sound production with barb 111 structure when shell fragment 2 rebound to reach the sound production effect.

Specifically, the barb 111 is integrally of an inverted L-shaped structure, the lower end of the barb extends upwards along the axis direction of the base 1, the upper end of the barb is bent to form a horizontal folded edge, and the horizontal folded edge extends towards the direction of the elastic sheet 2 and is located above the corresponding structure of the elastic sheet 2. When the elastic sheet 2 is stressed to move, the folded edge can collide with the elastic sheet 2.

The elastic sheet 2 comprises an action part 21 and a sound-producing part 22 which are fixedly connected, wherein the action part 21 can deform under the extrusion action of the button 4 and drive the elastic sheet 2 to move relative to the accommodating groove 11; the sound emitting portion 22 can emit sound by colliding with the barb 111.

Specifically, the structure of the action portion 21 is as shown in fig. 5, and the action portion is symmetrical left and right, and includes two independent elastic arms, and any elastic arm is a bar structure, and includes a fixing portion, a necking contact portion and an extension portion in sequence, wherein the fixing portion can be fixedly connected with the sounding portion 22, and the distance between two opposite elastic arms is gradually reduced from the fixing portion to the necking contact portion, and is gradually increased from the necking contact portion to the extension portion, and a horn mouth structure can be formed between two opposite extension portions.

Specifically, a necking is formed between two oppositely-arranged necking contact portions, and the convex block 42 on one side of the button 4 can elastically expand the necking through the necking contact portions, so that the elastic sheet 2 is impacted towards the upper side of the accommodating groove 11 due to stress deformation.

In addition, the sound emitting portion 22 includes a main body 221 and a hook 222, wherein the main body 221 can be fixedly connected with the fixing portion in the operation portion 21. As shown in fig. 6-7, the main body 221 of the sound-emitting portion 22 is a sheet-like structure, and the hook 222 is bent at a certain angle relative to the main body 221 in the direction of the barb 111.

It should be noted that the hook 222 may be formed by bending a part of the assembly on the body 221, or may be formed by fixing a flap on the surface of the body 221 by welding or the like.

At least one side edge of the catch 222 is bent outward with respect to the body 221. In order to enhance the durability of the ultra-thin sound switch, as an optional embodiment, two hooks 222 are symmetrically disposed on the body 221, and at this time, the two hooks 222 are respectively located at two ends of the same surface of the body 221.

As shown in fig. 5, the length of the sound emitting portion 22 is longer than the length of the operating portion 21.

In addition to the above mentioned push button 4, the switch comprises an upper cover 3 and a spring 5. The button 4 can be under the effect of upper cover 3 along the axial with shell fragment 2 cooperation carry out reciprocating motion with base 1.

The utility model also provides a keyboard, this keyboard includes above-mentioned ultra-thin sound production switch and key cap 5. Wherein, the upper surface of button 4 is provided with column screens 41, and the key cap 5 is provided with buckle 51 with the one side of button 4 contact, and buckle 51 can lock on screens 41.

The key cap 5 can be fixed on the upper surface of the push button 4 by the snap 51 and the detent 41 which are engaged with each other, as shown in fig. 8.

As an alternative embodiment, the cross-sectional configuration of the detent 41 includes at least a partial curve, as shown in FIG. 9, in which case the detent 41 in FIG. 9 is a cylindrical configuration, although the detent 41 may be configured as shown in FIG. 10.

The latch 51 has a certain elasticity, and thus can be firmly engaged with and fixed to the detent 41.

As an alternative embodiment, the number of detents 41 is multiple and all the detents 41 are evenly distributed on the upper surface of the button 4. The clamping positions 41 which are uniformly distributed can ensure that the matching buckling force and stability of the keycap 5 and the button 4 are better.

The switch structure is also required to be fitted with a balance bar 6 in use, the mounting position of which is shown in figures 1 and 2.

In addition, in order to ensure the thickness of the switch, the side edge of the keycap 5 is bent towards the position of the button 4 and extends to cover the side edge of the button 4 or the upper cover 3; and since the catch 51 protrudes outwardly relative to the lower surface of the key cap 5, the upper surface of the detent 41 is disposed no higher than the upper surface of the button 4.

The thickness of the switch can be effectively reduced through the two structures.

It should be noted that the keyboard includes, in addition to the switch, an iron plate 8, a PCB 9, and an infrared pair tube 10, which are located below the switch and can fix the switch.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
