[0002] With the rapid development of computer technology, the performance and comfort of keyboards, as an important device for human-computer interaction, are receiving increasing attention from users. However, traditional keyboards often produce considerable noise when typing, which not only affects the user experience but may also disturb the surrounding environment. To address this issue, various noise-reducing keyboards have emerged on the market, but these products often suffer from problems such as complex structures, high manufacturing costs, or poor noise reduction effects. Furthermore, the various components in existing keyboards require multiple screws for connection and fixation, making installation and disassembly cumbersome.

[0003] Therefore, based on the above problems, if a keyboard with a simple structure, low manufacturing cost, and significant noise reduction effect can be designed, and if the keyboard is connected and fixed magnetically for installation and disassembly, further improving the user experience, the above problems can be solved well.

[0007] Furthermore, the signal conduction component includes a PCB board, a positioning plate, and several switches arranged sequentially from bottom to top. A foam board is disposed between the PCB board and the positioning plate. The PCB board, the foam board, and the positioning plate are fixedly engaged. The positioning plate is limited and engaged on the PCB board by several screws. Several switches are limited and engaged with several keycaps. The positioning plate is limited and engaged with the buffer plate and several buffer pads respectively.

[0019] like Figure 1 , Figure 2 and Figure 7As shown, in this embodiment, the present invention includes a lower cover 1, a signal conduction component 2, an upper cover 3, and a plurality of keycaps 4 arranged sequentially from bottom to top. The plurality of keycaps 4 are in limiting cooperation with the signal conduction component 2. A buffer plate 5 is provided between the lower cover 1 and the signal conduction component 2. The buffer plate 5 is in limiting cooperation within the lower cover 1. A plurality of buffer pads 30 are provided on the upper cover 3. The signal conduction component 2 is in limiting cooperation with the buffer plate 5 and the plurality of buffer pads 30 respectively. Therefore, the lower cover 1 provides support and limits for the signal conduction component 2, the buffer plate 5, and the upper cover 3. The signal conduction component 2 receives the signal from the consumer striking the silenced keyboard and transmits the processed signal to the computer. The buffer plate 5 separates the lower cover 1 and the upper cover 3, absorbing the vibration when the consumer presses the signal conduction component 2 and preventing it from being transmitted to the outside of the lower cover 1 and the upper cover 3, thus significantly reducing noise. The upper cover 3 and the lower cover 1 work together to seal and protect the silenced keyboard. Several keycaps 4 protect the switches 22 on the signal conduction component 2, improving the user experience when striking the switches 22.

[0020] like Figure 2 and Figure 3 As shown, in this embodiment, the lower cover 1 is provided with a plurality of first magnets 10, and the bottom of the lower cover 1 is provided with a plurality of pads 11. Thus, the lower cover 1 provides support and fixation for the plurality of first magnets 10. The lower cover 1 is attracted to the second magnets 31 on the upper cover 3 via the first magnets 10, making it easy to disassemble and replace the lower cover 1 and the upper cover 3. The pads 11 support the silenced keyboard, increasing its overall height to accommodate different hand sizes and making typing easier for users.

[0021] like Figure 2 and Figure 4As shown, in this embodiment, the signal conduction component 2 includes a PCB board 20, a positioning plate 21, and a plurality of shafts 22 arranged sequentially from bottom to top. A foam board 23 is disposed between the PCB board 20 and the positioning plate 21. The PCB board 20, the foam board 23, and the positioning plate 21 are fixedly engaged. The positioning plate 21 is limited and engaged on the PCB board 20 by a plurality of screws 24. The plurality of shafts 22 are limited and engaged with a plurality of keycaps 4. The positioning plate 21 is limited and engaged with the buffer plate 5 and a plurality of buffer pads 30 respectively. Therefore, the PCB board 20 receives the signal from the shaft 22 pressing and transmits the processed signal to the computer. The positioning plate 21 supports and positions the shafts 22. The foam board 23 separates the PCB board 20 and the positioning plate 21, absorbs the vibration when the consumer presses the shaft 22, and reduces noise. The screws 24 connect the positioning plate 21 and the PCB board 20. The buffer pad 30 positions and guides the positioning plate 21, and also partially reduces noise.

[0022] like Figure 5 and Figure 6 As shown, in this embodiment, the upper cover 3 is an aluminum upper cover. Therefore, the aluminum upper cover 3 provides the following advantages: 1. Better structural support, making the overall silenced keyboard more robust and durable, ensuring the keyboard body will not deform even after multiple disassemblies and reassemblies. 2. The aluminum upper cover reduces internal cavity noise, resulting in a purer and softer typing sound, greatly improving the user's typing experience. 3. Aluminum alloy has excellent heat dissipation properties; the aluminum upper cover 3 can quickly dissipate heat generated inside the keyboard, maintaining its stability and reliability. 4. Aluminum alloy also has strong corrosion resistance, resisting the erosion of various chemicals and extending the service life of the upper cover 3.

[0023] like Figure 2 As shown, in this embodiment, the buffer plate 5 is a silicone plate, and the buffer pad 30 is a silicone pad. Therefore, the buffer plate 5 is a silicone plate, and the buffer pad 30 is a silicone pad. Because silicone is a highly elastic material, 1. it can fill the internal cavity of the silenced keyboard, significantly reducing loud noise during keystrokes, thus achieving noise reduction. 2. The silicone has a cushioning effect, reducing finger fatigue and improving the user experience over long-term use. 3. The silicone also has acid and alkali resistance, high temperature resistance, and other properties, resisting the corrosion of various chemicals and greatly improving the stability and reliability of the internal structure of the silenced keyboard. 4. The silicone provides waterproofing and dustproofing, further enhancing the stability of the internal structure of the silenced keyboard.

[0024] like Figure 6 As shown, in this embodiment, the upper cover 3 is further provided with a plurality of second magnets 31, which are attracted and engaged with a plurality of first magnets 10. Thus, the upper cover 3 provides support and fixation for the plurality of second magnets 31, and the attraction and engagement of the first magnets 10 with the second magnets 31 facilitates the disassembly and replacement of the lower cover 1 and the upper cover 3.

[0025] In this embodiment, the working principle of this utility model is as follows:

[0026] like Figures 1 to 8 As shown, the lower cover 1 is placed on the table by several pads 11. When the consumer presses several keycaps 4, he / she will also press several switches 22. The PCB board 20 converts the key press signal and transmits the signal to the computer to complete the typing process.

[0027] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
