[0002] In modern office and life settings, keyboards are frequently used input devices. However, traditional keyboards generate considerable noise when typing. This noise can easily disturb others and affect the quiet atmosphere of the office environment. It can also negatively impact the user's work performance and mood. The noise problem of traditional keyboards is particularly prominent in places with strict requirements for environmental noise, such as libraries, study rooms, and open office areas.
[0003] Furthermore, frequent keystrokes cause rapid wear and tear on the keycaps and internal keyboard structure, shortening the keyboard's lifespan and increasing user costs. While some noise-canceling keyboards exist on the market, most offer only unsatisfactory noise reduction and lack effective designs to improve keycap durability.
[0004] Publication number: CN218826771U. A noise-reducing sleeve is mounted on a circuit board and abuts against a fixing plate. Between the fixing plate and the circuit board, the noise-reducing sleeve has multiple clearance holes, each corresponding to a key, through which the keys are electrically connected to the circuit board. The noise-reducing sleeve for the noise-reducing keyboard provided in this application serves to isolate and absorb noise, as well as to buffer and dampen the fixing plate and the circuit board.
[0005] To address the aforementioned issues, traditional keyboards generate significant noise during keystrokes and the keycaps wear down easily when struck. Therefore, we have developed a noise-reducing keyboard with excellent keycap noise reduction. Utility Model Content

[0022] Please see Figure 1-3 A noise-reducing keyboard with good keycap noise reduction effect includes a keyboard body 1. The keyboard body 1 is rectangular in shape, and multiple keycaps 3 are provided on the top surface of the keyboard body 1. The keycaps 3 are trapezoidal in shape, and anti-slip sleeves 2 are provided on the outside of the keycaps 3. Multiple noise-reducing cotton pads 4 are provided on the bottom of the keycaps 3. The keyboard also includes:
[0023] The noise reduction component is installed at the bottom of keycap 3 to reduce the noise generated by the keyboard during use and improve the lifespan of the keycap.
[0024] Furthermore, multiple keycaps 3 are fixedly connected to the top of the keyboard body 1, and the top of the multiple keycaps 3 are covered with anti-slip sleeves 2, and the bottom of the keycaps 3 is fixedly connected with a sound-absorbing cotton pad 4, and the sound-absorbing cotton pad 4 is provided with a thickened layer on the outside.
[0025] Furthermore, a housing 5 is fixedly connected to the bottom center of the keycap 3, and the outer surface of the housing 5 is cylindrical, the inside of the housing 5 is hollow, and a groove 6 is provided at the bottom of the housing 5.
[0026] Furthermore, the noise reduction assembly includes a housing 5, a connecting post 10, a diagonal rod 11, a triangular protrusion 12, and a diagonal block 13. The triangular protrusion 12 is fixedly connected to both ends of the housing 5, and the diagonal block 13 is slidably connected to the outer diagonal surface of the triangular protrusion 12. The diagonal block 13 has a diagonal surface on its outer side, and the diagonal rod 11 is fixedly connected to one end of the outer side of the diagonal block 13. The connecting post 10 is slidably connected to the center of the outer side of the diagonal rod 11.
[0027] Furthermore, the interior of the connecting column 10 is hollow, and holes are provided at both ends of the outer side of the connecting column 10. An inclined rod 11 is slidably connected inside the holes, and a baffle 9 is fixedly connected to the top of the connecting column 10.
[0028] Furthermore, a spring 8 is fixedly connected to the top of the baffle 9, and a hollow column 7 is fixedly connected to the top of the spring 8. The hollow column 7 has a cross-shaped hollow interior, and the top of the hollow column 7 is fixedly connected to the interior of the keycap 3.
[0029] Structural Description: Keyboard Body 1: The main body of the entire keyboard, with an external cuboid shape. It serves as the foundation for the installation and fixation of other components, providing a platform for supporting and installing components such as keycaps 3, and carrying the keyboard's circuitry and other core components.
[0030] Anti-slip sleeve 2: It is fitted on the top of the keycap 3. Its main function is to increase the friction between the fingers and the keycap. When the user presses the key, the anti-slip sleeve 2 can help the fingers control the keycap better, reduce the occurrence of accidental presses, and improve the accuracy and comfort of key operation.
[0031] Keycap 3: The exterior is trapezoidal and is the part that the user directly touches and operates. Pressing keycap 3 triggers the keyboard's input function. The bottom of keycap 3 is connected to other components to achieve noise reduction and stability.
[0032] Noise-absorbing pad 4: Located on the bottom outer side of keycap 3, and with a thickened layer on the outside. When keycap 3 is pressed, noise-absorbing pad 4 will be squeezed, and its own elasticity and softness will absorb the vibration and sound generated by keycap 3, thereby reducing the noise generated when the keyboard is used.
[0033] Outer shell 5: It is fixedly connected to the bottom center of the keycap 3. The outer shell is cylindrical and the inner shell is hollow. The outer shell 5 mainly serves to protect the internal noise reduction components and also provides space for the installation and fixation of the internal components. The bottom of the outer shell has a groove 6, which works in conjunction with the internal structure to play a certain role in the noise reduction process.
[0034] Groove 6: Located at the bottom of housing 5, it may be used to cooperate with other components, such as providing space for the movement of some components when the muffler is working, or playing a certain positioning and connecting role in the structure.
[0035] Hollow column 7: The inside is cross-shaped and hollow. The top is fixedly connected to the inside of the keycap 3. The function of the hollow column 7 is to connect the keycap 3 and the spring 8 and other components below. When the keycap 3 moves up and down, it drives the spring 8, the baffle 9 and other components to move and transmit force.
[0036] Spring 8: The top is fixedly connected to the hollow column 7, and the bottom is fixedly connected to the baffle 9. Spring 8 is elastic. When the keycap 3 is pressed, it is compressed and stores elastic potential energy. When the finger releases the keycap 3, spring 8 restores its deformation and releases elastic potential energy, pushing the keycap 3 to bounce back. At the same time, it plays a role in buffering and shock absorption in this process, reducing the generation of noise.
[0037] Baffle 9: The top is fixedly connected to the spring 8, and the bottom is fixedly connected to the connecting post 10. Baffle 9 plays a connecting and fixing role in the whole structure, connecting the spring 8 and the connecting post 10 so that they can work together, and plays a certain limiting and guiding role when the keycap 3 moves.
[0038] Connecting post 10: The interior is hollow and both ends of the exterior have holes. A slanted rod 11 is slidably connected inside the holes. The top of the connecting post 10 is fixedly connected to the baffle 9. When the keycap 3 moves up and down, the connecting post 10 moves together with the baffle 9. Through the slanted rod 11 inside and other components, it achieves the functions of noise reduction and buffering.
[0039] Diagonal bar 11: It is slidably connected to the hole in the connecting post 10 at the center of the outside, and one end is fixedly connected to the beveled block 13. When the keycap 3 moves downward, the diagonal bar 11 slides in the connecting post 10 and pushes the beveled block 13 to move along the inclined surface of the triangular protrusion 12, which disperses and transforms the impact force on the keycap 3, and plays a role in buffering and shock absorption.
[0040] Triangular protrusion 12: It is fixedly connected to both ends of the inner shell 5 and has an external bevel. The bevel of triangular protrusion 12 and the bevel of bevel block 13 cooperate with each other. When the bevel rod 11 pushes the bevel block 13 to move, the bevel block 13 slides along the bevel of triangular protrusion 12. Through this structure, the impact force of keycap 3 is converted into other forms of energy such as friction force, thereby achieving the effect of noise reduction and buffering.
[0041] Beveled block 13: It has a beveled surface on the outside and a beveled rod 11 fixedly connected to one end. It is slidably connected to the beveled surface of the triangular protrusion 12. The beveled block 13 moves along the beveled surface of the triangular protrusion 12 under the push of the beveled rod 11. Through its own movement and interaction with the triangular protrusion 12, it disperses and buffers the impact force of the keycap 3. It is an important component of the noise reduction assembly.
[0042] When keycap 3 is pressed, keycap 3 moves downward, causing the hollow column 7, spring 8, and baffle 9, which are fixedly connected to it, to move downward together. Spring 8 is compressed, generating elastic potential energy. At the same time, connecting column 10, which is fixedly connected to baffle 9, also moves downward, causing the inclined rod 11 in the hole inside the connecting column 10 to slide to both sides under the action of triangular protrusion 12 and inclined side block 13. Since the inclined side block 13 is slidably connected to the inclined surface of triangular protrusion 12, the sliding of the inclined rod 11 will cause the inclined side block 13 to move upward along the inclined surface of triangular protrusion 12, thereby converting part of the impact force on keycap 3 into frictional force between inclined side block 13 and triangular protrusion 12 and elastic potential energy of spring 8, playing a buffering role, reducing the hard collision between keycap 3 and keyboard body 1, and thus reducing noise. In addition, the sound-absorbing cotton pad 4 at the bottom of keycap 3 also... When the keycap 3 is pressed down, it is squeezed, further absorbing vibration and sound. When the finger releases the keycap 3, the spring 8 returns to its original shape, releasing elastic potential energy and pushing the baffle 9, connecting post 10 and hollow post 7 upward, causing the keycap 3 to rebound. During the rebound, the slant rod 11 slides upward within the connecting post 10, and the slant block 13 slides downward under the action of the triangular protrusion 12, continuing to play a role in buffering and shock absorption, ensuring that the keycap 3 rebounds smoothly and reducing the noise generated during the rebound. At the same time, the sound-absorbing cotton pad 4 will also return to its original shape, preparing for the next keystroke. The anti-slip sleeve 2 can increase the friction between the finger and the keycap 3, allowing the user to operate the keys more accurately; while the thickened layer of the sound-absorbing cotton pad 4 can better absorb sound and vibration, working together with the sound-absorbing components to achieve a good sound-absorbing effect and improve the keyboard user experience.
