Description

Technical Field

[0001] The present application relates to the field of buttons, and in particular to a switch button with an improved sound-generating structure. Background Art

[0002] Existing magnetic switch technology is widely used in computer keyboards and other key devices that require fast response times. Its characteristics include sensitive keys and a uniform feel, meeting user needs in various scenarios. However, the switch core design of these keys is typically a flat-bottom structure. While this design is relatively simple to manufacture and assemble, it does not provide an ideal user experience in actual use, especially with regard to the sound of pressing and releasing the key.

[0003] Specifically, during the operation of existing magnetic axis keys, when the flat bottom of the shaft core collides with the base, the sound produced is relatively dull and lacks crisp feedback. This muffled sound affects the user's experience of using the keys to a certain extent, especially in scenarios that require fast and continuous operations. The sound of the keys often appears not bright enough and lacks a sense of layering and feedback. In addition, since the flat bottom structure forms a large contact surface with the base during the collision, this also causes a certain degree of obstruction in the propagation of sound, making the overall sound quality low and not transparent. This sound defect not only reduces the user's subjective satisfaction, but also makes the key operation lack a clear and definite sense of response, and cannot provide pleasant feedback similar to mechanical axis keys.

[0004] The main reason for the above shortcomings is that the flat-bottom design of the shaft core lacks the characteristics of deformation and rebound during impact. The generation of sound relies on direct hard collision and lacks optimization of sound quality. The large contact surface between the shaft core and the base causes the energy of the impact to be more dispersed, making it difficult to form a concentrated and high-frequency sound, resulting in the keystroke sound performance being less crisp. These problems are manifested in the user experience as the key operation sound is monotonous and lacks vitality. After long-term use, the change of sound will also be affected by wear, further exacerbating the key sound problem. Utility Model Content

[0005] The present application aims to overcome at least one of the shortcomings of the prior art and to provide a switch button with an improved sound-generating structure. The improved structure of the impact surface of the button reduces the direct contact area between the shaft core and the base, so that the energy of the impact can be transmitted more concentratedly, thereby improving the user's auditory feedback and overall user experience, helping to enhance the responsiveness of the button, and also improving the durability of the button and the stability of the sound quality to a certain extent.

[0006] To achieve the above-mentioned purpose, the present application discloses a switch button with an improved sound-producing structure, which includes a shell, an axis core installed in the shell, and a reset spring located in the shell and used to drive the axis core to reset after movement, wherein the inner bottom surface of the shell is provided with a bottom groove adapted to the axis core, and the axis core extends downwardly with a shaft rod that cooperates with the bottom groove; the bottom end of the shaft rod is spherical, and when working, the spherical bottom end collides with the inner bottom surface of the bottom groove to produce sound.

[0007] As an optional technical solution, the inner bottom surface of the bottom groove is arc-shaped and convex, which further improves the sound.

[0008] As an optional technical solution, the shell includes a base and an upper cover that cooperates with the base, and the bottom groove is arranged on the base.

[0009] As an optional technical solution, a magnetic block is installed on the shaft core, and correspondingly, an induction unit is installed in the shell, which is opposite to the magnetic block and is used to sense the change of magnetic force.

[0010] As an optional technical solution, the shaft includes a base section and a detachable spherical structure installed at the bottom end of the base section. The spherical structure is detachable, which facilitates the replacement of the impact bottom end with different materials to form different sounds.

[0011] Compared with the prior art, this application has at least one of the following beneficial effects:

[0012] 1. Improved sound feedback: By designing the bottom end of the shaft core into a spherical shape and providing an arc-shaped raised bottom groove at the bottom of the shell, the direct contact area between the shaft core and the base is effectively reduced, making the impact energy more concentrated, thereby providing crisper sound feedback and enhancing the user's listening experience.

[0013] 2. Enhanced responsiveness: The spherical bottom design enables the buttons to provide faster and clearer feedback during operation, allowing users to experience better responsiveness during use, making it suitable for application scenarios that require fast and continuous operations.

[0014] 4. Stability of sound quality: By reducing the direct contact area between the shaft core and the base, the sound changes caused by wear are reduced, the stability of the sound quality is improved, and the sound remains consistent after long-term use of the keys.

[0015] 5. Sound adjustability: The spherical structure at the bottom of the shaft core is detachable, and the impact bottom can be replaced with different materials to produce different sound effects to meet users' diverse needs for key sound effects.

[0016] The above-listed beneficial effects are not exhaustive and other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description sections of this application. BRIEF DESCRIPTION OF THE DRAWINGS

However, it should be understood that the present disclosure can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the present disclosure more complete and fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments.

[0022] It should be understood that like reference numerals refer to like elements throughout the drawings. In the drawings, the dimensions of some features may be distorted for clarity.

[0023] It should be understood that the terms used in the specification are only used to describe specific embodiments and are not intended to limit the present disclosure. All terms (including technical and scientific terms) used in the specification have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, the techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered part of the authorization specification.

[0024] As used in this specification, the singular forms "a," "an," "said," and "the" include the plural forms unless otherwise expressly stated. The terms "include," "comprise," and "contain" as used in this specification indicate the presence of the claimed features, but do not exclude the presence of one or more additional features. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items. Example

[0025] This embodiment discloses an improved key structure, comprising a housing 1, a shaft core 2 mounted within the housing 1, and a return spring 3 for returning the shaft core 2 to its original position after movement. Through reasonable structural design and coordinated componentry, tactile feedback and audible prompts are achieved during key operation.

[0026] Refer to the attached Figure 1 and 2 The housing 1 of the button is composed of a base 101 and an upper cover 102 that cooperates with the base 101 . The upper cover 102 is tightly combined with the base 101 to form a closed cavity for accommodating the shaft core 2 and the return spring 3 .

[0027] Refer to the attached Figure 2 The inner bottom surface of the base 101 is provided with a bottom groove 103 adapted to the shaft core 2 .

[0028] Extending downward from one end of the shaft core 2 is a shaft 201 that mates with the bottom groove 103. The bottom end 202 of the shaft 201 is spherical. When pressed, the spherical bottom end 202 collides with the inner bottom surface of the bottom groove 103, producing a distinctive sound. The spherical design concentrates the impact, resulting in a crisper sound. This concentrated impact releases the impact energy more effectively, creating a clear and penetrating sound effect, improving sound recognition and operational feedback.

[0029] Specifically, the reason why the impact of the spherical structure can improve the sound is that: first, the spherical shape of the bottom end 202 can concentrate the impact on one point, thereby releasing the impact energy more effectively and forming a crisp and penetrating sound. This concentrated impact method can increase the loudness and clarity of the sound, thereby making the sound feedback of the key clearer. In addition, the spherical structure can provide instantaneous high-energy transfer during impact, making the sound effect more prominent, especially in application scenarios that require obvious sound prompts. It has significant advantages. In addition, the spherical structure can cause the vibration to propagate more naturally and continuously during impact, thereby forming a clearer and more textured sound. This design makes the sound of the key have better repeatability and stability, and can produce consistent sound effects regardless of how the pressing force changes.

[0030] As an improved technical solution, refer to the attached Figure 3The inner bottom surface of the bottom groove 103 is an arc-shaped protrusion. The main purpose of this design is to further enhance the sound effect of the key, while improving the durability of the key and the stability of operation. The main purpose of this arc-shaped protrusion design is to further enhance the sound effect of the key, while improving the durability of the key and the stability of operation. The arc-shaped protrusion of the bottom groove 103 allows the shaft core 2 to contact the bottom surface more accurately when pressed, thereby achieving a concentrated impact and producing a clear and penetrating sound effect. Compared with the traditional flat bottom groove 103 design, the arc-shaped protrusion can better achieve point-to-point impact.

[0031] In this embodiment, the reset spring 3 is located on the periphery of the shaft core 2 and is installed between the shaft core 2 and the base 101 through pre-compression to quickly reset the shaft core 2 after the key is released. The upper end of the shaft core 2 is maintained in the initial position under the action of the spring. When the key is pressed, the shaft core 2 moves downward, and the spherical part at the bottom end of the shaft 201 collides with the bottom surface of the bottom groove 103, producing a sound. Then the elastic force of the reset spring 3 returns the shaft core 2 to the initial position, completing a key action. The pre-compression design of the reset spring 3 not only improves the response speed of the key, but also ensures that each press and release of the key maintains a consistent force, making the user's operating experience smoother.

[0032] In specific applications, such as on electronic device input devices like keyboards, the buttons can provide good tactile feedback and sound prompts, giving users clear feedback during operation. By adjusting the material of the spherical structure, different impact sound effects can be obtained to meet different usage needs.

[0033] Building on the above structure, shaft 201, as an optional design, includes a base section and a spherical member removably mounted at the base end. This design allows users to swap out the impact member for different materials to achieve different sound effects. For example, if a softer sound is desired, a flexible spherical member can be selected; if a crisper sound is desired, a metal spherical member can be selected. This way, users can select the appropriate sound effect based on specific application scenarios and personal preferences, greatly improving the adaptability of the key.

[0034] For example, in gaming equipment or certain industrial equipment, users may tend to choose crisper sounds to ensure that each operation has obvious sound feedback, which can improve the certainty and efficiency of the operation.

[0035] In practical applications, this structure can be applied to magnetic axis keys. To achieve magnetic triggering of magnetic axis keys, the keys contain a magnet and a sensing unit. The magnet is mounted on the shaft core 2, while the sensing unit is fixed within the housing 1, opposite the magnet. When the key is pressed and released, the change in the position of the magnet causes the sensing unit to detect changes in magnetic force, thereby sensing the key status. This design of a magnetic axis key is state-of-the-art and enables non-contact status detection, reducing mechanical wear and improving the reliability and service life of the key.

[0036] Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications may be made to the exemplary embodiments of the present disclosure without departing substantially from the spirit and scope of the present disclosure. Therefore, all such changes and modifications are intended to be within the scope of protection of the present disclosure as defined by the appended claims.
