[0011] The utility model adopts the above technical solution, which has the following beneficial effects:

[0012] 1. The button adopts a split structure design, a magnet is built in the guide column of the lower button, the guide column is slotted but not a through hole, but the bottom is closed; when the button is pressed down, the bottom of the guide column contacts the middle contact point of the base, because the two are plastic and plastic contact, the impact sound is small, and the material of the two can be changed to adjust the sound effect of the button according to user demand.

[0013] 2. The button adopts a full wall structure, the top of the button is designed as an upper button, the wall and the downward extending guide column are a lower button, the full wall surface is slidingly connected with the base, and no guide protrusion needs to be arranged.

[0014] 3. The upper button is provided with a downward positioning column, which can prevent the magnet from loosening when pressed. BRIEF DESCRIPTION OF DRAWINGS

[0015] The utility model will be further explained in detail in combination with the drawings and specific embodiments:

[0016] Figure 1 It is a structural schematic view of the utility model;

[0017] Figure 2 It is a sectional view of the utility model;

[0018] Figure 3 It is a schematic view of the upper button and the lower button adopting rivet joint connection (rivet point is above).

[0019] Figure 4 It is a schematic view of the upper button and the lower button adopting rivet joint connection (rivet point is below). SPECIFIC EMBODIMENT

[0020] As shown in Figure 1-4 The utility model discloses a change sound switch structure, including base 1 and the button of setting on base 1 and can move up and down, button and base 1 are connected with reset spring 2. The button includes the upper button 3 and the lower button 4 that are connected together, the lower button 4 is equipped with wall structure 41 on the outer periphery side, the outer side plane of wall structure 41 and the window of base 1 top slidingly sleeve joint, the middle part of lower button 4 is equipped with the guide column 42 that sets down and extends, and the guide column 42 and the guide groove 11 in the inside of base 1 slidingly sleeve joint.

[0021] The utility model discloses, button adopts full enclosure wall structure 41, and the top of button is designed as upper button 3 with the cover of opening, and the enclosure wall and the downwardly extending guide column 42 are lower button 4, and the full enclosure wall surface is slidably connected with base 1, and it is not necessary to set up the guide boss (if button adopts the middle split structure, namely the upper button 3 of the enclosure wall above, and the lower button 4 of the middle below with the guide column 42 part, then the middle part will exist the gap, influence the smoothness of the top window of the sliding fit of base 1, in addition, need to set up the convex rib with the recess groove sliding connection of base 1 corresponding on the side of button).

[0022] The guide column 42 is internally slotted, but the bottom of the guide column 42 is a closed structure, and a magnet 5 is embedded in the inner bottom of the guide column 42; the guide column 42 of the lower button 4 and the base 1 are both formed of plastic material. The bottom of the guide column 42 of the lower button 4 collides with the middle contact point 22 of the base 1, realizing the collision contact of plastic to plastic, and reducing the impact sound. At the same time, the materials of the two can be changed to adjust the key sound effect required by the user. For example, the upper button 3 can be made of POM material, and the lower button 4 (the guide column 42 is integrally formed with the lower button 4 as a whole, that is, the material of the guide column 42 is the same as that of the lower button 4) and the base 1 can be made of PA / POM / PC material.

[0023] The bottom of the upper button 3 is provided with a positioning column 31, which extends into the inside of the guide column 42 and abuts against the top of the magnet 5. This design can avoid the loosening of the magnet 5 when the button is pressed, thereby affecting the conduction performance.

[0024] The upper button 3 is nested and fixed in the enclosure wall structure 41 of the lower button 4, and the upper button 3 closes the top opening of the guide column 42 of the lower button 4 like a lid. The upper button 3 and the lower button 4 can be connected together by riveting.

[0025] As shown in Figure 3 , when the upper button 3 and the lower button 4 are connected by riveting, a plurality of rivet columns 43 are arranged on the middle horizontal plate of the lower button 4, and the upper button 3 is provided with a riveting hole 32 corresponding to each rivet column. At this time, the riveting point is above the middle horizontal plate of the lower button 4.

[0026] As shown in Figure 4 , when the upper button 3 and the lower button 4 are connected by riveting, a plurality of riveting holes 44 are arranged on the middle horizontal plate of the lower button 4, and the upper button 3 is provided with a rivet column 33 corresponding to each riveting hole 44. At this time, the riveting point is below the middle horizontal plate of the lower button 4.

[0027] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
