Description

Technical Field

[0001] This utility model relates to the field of keyboard switches, and more specifically, to a keyboard switch and keyboard with a pure pressing sound. Background Technology

[0002] When a traditional button moves up and down relative to the housing, it not only causes the torsion spring to strike the housing and produce a feedback sound, but also generates a collision sound due to the collision between the button and the housing. This collision sound is noise, which interferes with the clear and distinct operation feedback that should be provided. It makes the feedback sound impure and unpleasant, resulting in a significant reduction in user experience, and urgently needs to be improved. Utility Model Content

[0003] In view of this, the present invention provides a keyboard switch with a pure pressing sound, which can absorb the collision sound formed by the contact between the button and the housing, effectively filter out all unnecessary noise, and retain only the feedback sound, making the feedback sound pure and pleasant to listen to, thereby improving product quality and enhancing user satisfaction.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A keyboard switch with a pure pressing sound includes a housing, a button, a spring, a torsion spring, and a mute structure. The button can move up and down relative to the housing to turn the switch on and off. The torsion spring is driven by the button and can strike the housing to produce a feedback sound. When the button moves down, it strikes the housing to produce a first impact sound. When the button moves up, it strikes the housing to produce a second impact sound. The mute structure includes a first mute element for eliminating the first impact sound and a second mute element for eliminating the second impact sound.

[0006] This system achieves refined sound management during button presses, effectively filtering out discordant noises and retaining only crisp, pleasant feedback sounds to create an immersive user experience. When a button is pressed, the initial impact sound from its contact with the housing is absorbed by the first noise-dampening component; conversely, when the button rebounds, any potential secondary impact sound is efficiently suppressed by the second noise-dampening component. This effectively filters out all unnecessary noise, leaving only the pure, crisp feedback sound generated by the torsion spring drive, greatly enhancing user satisfaction. Whether gaming or working, the clear audio feedback instills confidence in every click and reduces fatigue.

[0007] Preferably, the first muffler is made of silicone and is connected to the housing or button.

[0008] Silicone, as a high-performance polymer, possesses unique physical properties that make it an ideal sound insulation material. Its excellent flexibility and elasticity effectively cushion impacts between buttons and the housing, significantly reducing vibration transmission and thus lowering noise levels. Silicone also has a wide temperature range (-60℃ to +250℃), strong chemical stability, and is not prone to aging or deterioration. This means it maintains stable performance even under extreme conditions, extending its service life.

[0009] Preferably, the housing is provided with a sliding groove, the button is provided with a sliding post, the sliding post is embedded in the sliding groove and can slide relative to the sliding groove, and the first muffler is placed in the sliding groove.

[0010] The tight fit between the sliding column and the sliding groove ensures the smoothness and stability of the button's movement, minimizing potential jamming or friction, further reducing mechanical noise, and making the button's vertical movement more accurate. Since the first silencer is placed directly inside the sliding groove, it is less prone to displacement, enhancing overall reliability.

[0011] Preferably, the first silencing component is connected to the bottom of the slide column, or to the bottom of the slide groove, or is simply placed inside the slide groove without being connected to the slide column or the slide groove.

[0012] By connecting the first muffler to the bottom of the slide column or the bottom of the slide groove, or simply placing it in the slide groove without connecting it to the slide column or the slide groove, not only is the assembly versatility increased, but the optimal performance of the muffler under different stress conditions is also ensured.

[0013] Preferably, the button has a guide rib on its side, and the second muffler is made of silicone and is disposed on the top of the guide rib.

[0014] The guide rib guides the button's movement, and a second sound-absorbing component made of silicone is attached to the guide rib on the side of the button to eliminate potential impact sound waves and ensure pure feedback sound.

[0015] Preferably, the second noise-reducing component is a guide and shock-absorbing structure disposed on the side of the button. The guide and shock-absorbing structure includes a first side rib disposed on the side of the button, a second side rib disposed next to the first side rib and spaced apart from the first side rib, and an impact member located at the gap between the first side rib and the second side rib. The impact member is thin and elastic, and the highest point of the impact member is higher than the highest point of the first side rib and the second side rib.

[0016] By adding a pair of parallel side ribs (first and second) to the side of the button, with an impactor made of elastic material filling the space between them, a dynamic adjustment system is formed. When the button rebounds to the end of its travel, the impactor and the housing collide. The impactor, utilizing its elastic deformation, actively absorbs excess kinetic energy, effectively converting it into minute vibrations, ultimately achieving sound reduction. Its thin, sheet-like design, coupled with a slightly raised protrusion, ensures that the component colliding with the housing is always the impactor, thus guaranteeing the reliability of the noise reduction effect.

[0017] Another form of this solution could be a keyboard, including keyboard switches with a purely audible pressing sound as described above.

[0018] The advantages of this utility model compared to the prior art are:

[0019] This invention features a keyboard switch with a pure pressing sound, achieving refined sound management during key presses. It effectively filters out discordant noise, retaining only a crisp and pleasant feedback sound, creating an immersive operating experience. When the button is pressed, the initial impact sound generated by its contact with the housing is absorbed by a first noise-dampening component; similarly, when the button rebounds, any potential second impact sound is efficiently suppressed by a second noise-dampening component. This effectively filters out all unnecessary noise, leaving only the pure, crisp feedback sound generated by the torsion spring drive, greatly improving user satisfaction. Whether gaming or working, the clear audio feedback instills confidence with every click, while also reducing fatigue. Attached Figure Description

[0029] The technical solutions in this application will now be described with reference to the accompanying drawings. Example 1

[0030] This embodiment provides a keyboard switch with a pure pressing sound, including a housing 100, a button 200, a spring 300, a torsion spring 400, and a noise-reducing structure 500. The housing 100 includes a top cover 101 and a base 102. The button 200 can move up and down relative to the housing 100 to realize the switching on and off. The torsion spring 400 is driven by the button 200 and can collide with the housing 100 to emit a feedback sound. When the button 200 moves down, it will collide with the housing 100 to emit a first collision sound. When the button 200 moves up, it will collide with the housing 100 to emit a second collision sound. The noise-reducing structure 500 includes a first noise-reducing element 510 for eliminating the first collision sound and a second noise-reducing element 520 for eliminating the second collision sound.

[0031] This system achieves refined sound management during button presses, effectively filtering out discordant noises and retaining only crisp, pleasant feedback sounds to create an immersive user experience. When button 200 is pressed, the initial impact sound generated by its contact with the housing 100 is absorbed by the first muffler 510; and when button 200 rebounds, any potential second impact sound is effectively suppressed by the second muffler 520. This effectively filters out all unnecessary noise, leaving only the pure, crisp feedback sound generated by the torsion spring 400, greatly improving user satisfaction. Whether gaming or working, clear audio feedback makes every click confident and reduces fatigue.

[0032] In this embodiment, the first silencing component 510 is made of silicone and is connected to the housing 100 or the button 200.

[0033] Silicone, as a high-performance polymer, possesses unique physical properties that make it an ideal sound insulation material. Its excellent flexibility and elasticity effectively cushion the impact between the button 200 and the housing 100, significantly reducing vibration transmission and thus lowering noise levels. Silicone also has a wide temperature range (-60℃ to +250℃), strong chemical stability, and is not prone to aging or deterioration. This means it maintains stable performance even under extreme conditions, extending its service life.

[0034] In this embodiment, the housing 100 is provided with a slide groove 110, the button 200 is provided with a slide post 210, the slide post 210 is embedded in the slide groove 110 and can slide relative to the slide groove 110, and the first muffler 510 is placed in the slide groove 110.

[0035] The tight fit between the slide column 210 and the slide groove 110 ensures the smooth and stable movement of the button 200, minimizing any potential jamming or friction, further reducing mechanical noise, and making the vertical movement of the button 200 more accurate. Since the first silencer 510 is directly placed inside the slide groove 110, it is less prone to displacement, enhancing overall reliability.

[0036] In this embodiment, the first muffler 510 is connected to the bottom of the slide groove 110. In other embodiments, the first muffler may be connected to the bottom of the slide column or simply placed in the slide groove without being connected to the slide column and the slide groove.

[0037] The various connection methods of the first muffler 510 not only increase the diversity of assembly, but also ensure the optimal performance of the muffler under different stress conditions.

[0038] In this embodiment, the second noise-reducing component 520 is a guide and shock-absorbing structure disposed on the side of the button 200. The guide and shock-absorbing structure includes a first side rib 521 disposed on the side of the button 200, a second side rib 522 disposed next to the first side rib 521 and spaced apart from the first side rib 521, and an impact member 523 located at the gap between the first side rib 521 and the second side rib 522. The impact member 523 is thin and elastic, and the highest point of the impact member 523 is higher than the highest point of the first side rib 521 and the second side rib 522.

[0039] By adding a pair of parallel side ribs 521 and 522 to the side of the button 200, with an impact element 523 made of elastic material filling the space between them, a dynamic adjustment system is formed. When the button 200 rebounds to the end of its travel, the impact element 523 and the housing 100 collide. The impact element 523 actively absorbs excess kinetic energy through its elastic deformation, effectively converting it into a small vibration, ultimately achieving the effect of reducing sound. Its thin, sheet-like design, coupled with a slightly raised protrusion, ensures that the component colliding with the housing 100 is always the impact element 523, thus guaranteeing the reliability of the noise reduction effect. Example 2

[0040] Unlike Embodiment 1, in this embodiment, the side of the button 200 is provided with a guide rib 220, and the second muffler 520 is made of silicone and is disposed on the top of the guide rib 220.

[0041] The guide rib 220 guides the rise and fall of the button 200. A second sound-absorbing component 520 made of silicone is attached to the guide rib 220 on the side of the button 200 to eliminate potential impact sound waves and ensure pure feedback sound.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
