Description

Technical Field

[0001] This application relates to the field of buttons, and particularly to a button with a special sound - generating structure. Background Art

[0002] As an important interface for human - machine interaction, buttons are used to receive user instructions or selections, activated by physical pressing or touching, etc., and then control devices or software to perform corresponding functions or operations. Their application scope is extremely wide, such as in daily household appliances (such as TV remote controls, microwave oven control panels), office equipment (computer keyboards, printer operation panels), industrial control devices or game entertainment devices (game console controllers, keyboards and mice), etc. in various fields, greatly facilitating people's lives and work.

[0003] There is a current button, including a pressing part and a carrier seat. When a force is applied to the pressing part, the pressing part moves towards the carrier seat, and it realizes sound generation through a shrapnel structure, that is: every time the pressing part is pressed, the shrapnel structure contacts the sound - generating structure of the carrier seat. At the moment when the shrapnel structure contacts the sound - generating structure, a striking sound is generated, which is beneficial to improving the user experience when using the button.

[0004] Every time the shrapnel structure contacts the sound - generating structure, the shrapnel structure needs to be reset to facilitate the next sound - generating operation. However, due to the material characteristics of the shrapnel structure itself, as the number of presses increases, the elasticity of the shrapnel structure will cause irreversible mechanical loss. Thus, as the usage time of the button increases, the striking sound emitted by the cooperation of the shrapnel structure and the sound - generating structure will change slowly. At this time, the sound emitted by the cooperation of the shrapnel structure and the sound - generating structure is difficult to meet the design requirements, and there is room for improvement. Summary of the Utility Model

[0005] In order to improve the consistency of the pressing sound generated when the user presses the button each time, this application provides a button with a special sound - generating structure.

[0006] The button with a special sound - generating structure provided by this application adopts the following technical solutions:

[0007] A button with a special sound - generating structure includes a carrier seat, a pressing handle, and a reset member for driving the pressing handle to reset. The carrier seat is provided with a cavity, the pressing handle is slidably arranged in the cavity, an impact part is arranged in the cavity, a sliding groove is opened along the geometric center to the edge of the impact part, the pressing handle includes a pressing part and a sliding part, the sliding part is slidably arranged in the sliding groove, and an impact surface is annularly arranged at the connection between the sliding part and the pressing part. When a force is applied to the pressing part, the sliding part follows the pressing part to slide along the sliding groove, and an impact sound will be emitted when the impact surface contacts the end surface of the impact part.

[0008] By adopting the above technical solution, when the user presses the pressing part, the sliding part moves synchronously with the pressing part, so that the sliding part slides along the sliding groove to drive the button handle to move toward the supporting seat. When the impact surface abuts against the impact part, an impact sound can be emitted. The mechanical structure involved in the sound generation is relatively simple, and the sound generated is relatively crisp. The present application utilizes the impact principle to generate sound. During the collision between the impact surface and the impact part, almost no mechanical loss is generated, which plays a positive guiding role in improving the consistency of the pressing sound generated each time the user presses the button.

[0009] Preferably, the tolerance fit relationship between the sliding groove and the sliding portion is a clearance fit.

[0010] By adopting the above technical solution, the tolerance matching relationship between the sliding groove and the sliding part is a clearance match, which allows the sliding part to slide smoothly along the sliding groove, while also helping to reduce the deflection of the sliding part when sliding along the sliding groove, thereby improving the stability of the handle when it moves along the bearing seat.

[0011] Preferably, a sound diffusion cover is provided along the edge of the impact surface, and a sound diffusion cavity is formed between the sound diffusion cover and the sliding portion.

[0012] By adopting the above technical solution, at the moment when the impact surface collides with the impact part and generates the impact sound, the impact sound quickly diffuses along the sound-scattering cavity. The diffusion effect of the sound-scattering cavity is helpful to enhance the tone of the impact sound, while also helping to maintain the timbre of the impact sound and reduce the probability of timbre distortion of the impact sound during propagation.

[0013] Preferably, the sound dissipation cover is arranged to expand outward from an end close to the impact surface to an end away from the impact surface.

[0014] By adopting the above technical solution, since the sound-scattering cover is arranged to expand outward, the impact sound is quickly transmitted along the sound-scattering cavity, which plays a positive guiding role in increasing the volume of the impact sound.

[0015] Preferably, the sliding portion is provided with auxiliary sound-emitting portions along both sides of the sound-scattering cover away from the sound-scattering cavity, and when the reset member drives the handle away from the bearing seat and reaches the limit position, the auxiliary sound-emitting portions abut against the bearing seat.

[0016] By adopting the above technical solution, when the reset member drives the handle away from the base to reach the extreme position, the power provided by the reset member drives the auxiliary sound-emitting part to collide with the supporting seat, thereby generating a secondary impact sound, that is, each time the user presses the handle, two impact sounds can be heard, which is beneficial to improving the user experience.

[0017] Preferably, the auxiliary sound-emitting portion is arranged to be inclined downward from an end close to the sound-scattering cover to an end far away from the sound-scattering cover.

[0018] By adopting the above technical solution, since the auxiliary sound-emitting part is arranged to be tilted downward, the contact area between the auxiliary sound-emitting part and the supporting seat is reduced, thereby reducing the impact area between the auxiliary sound-emitting part and the supporting seat, which is beneficial to reducing the volume when the auxiliary sound-emitting part collides with the supporting seat, so as to facilitate distinguishing the two impact sounds.

[0019] Preferably, the contour dimension of the impact portion is smaller than the contour dimension of the sound diffusion cavity.

[0020] By adopting the above technical solution, when the user presses the button handle, the bearing part quickly moves along the sliding groove to the bottom of the sliding groove, and at this time the impact part and the impact surface quickly approach each other. At this time, the air between the impact part and the impact surface is quickly compressed. Since the outline size of the impact part is smaller than the outline size of the sound diffusion cavity, the compressed air is quickly dispersed along the sound diffusion cavity, thereby reducing the probability of a delay between the time when the user applies the action on the button handle and the time when the impact part collides with the impact surface due to the presence of compressed air between the impact part and the impact surface.

[0021] Preferably, a magnetic block is provided at one end of the sliding portion away from the impact surface.

[0022] By adopting the above technical solution, a magnetic block can also be arranged on the sliding part to make it a magnetic axis button, which is highly practical.

[0023] Preferably, an installation groove is provided at one end of the sliding portion away from the impact surface, the installation groove is used to install the magnetic block, and an undercut structure is provided at the notch of the installation groove, the undercut structure is used to block the magnetic block in the installation groove.

[0024] By adopting the above technical solution, the fixed connection between the magnetic block and the sliding part can be easily achieved through the installation groove, and the installation position of the magnetic block in the installation groove can be limited by using the inverted structure, thereby improving the stability of the magnetic block when installed in the installation groove and reducing the probability of the magnetic block loosening or falling off along the installation groove.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. This application uses the impact principle to produce sound. During the collision between the impact surface and the impact part, almost no mechanical loss is generated, which plays a positive guiding role in improving the consistency of the pressing sound generated by the user each time the key is pressed;

[0027] 2. The sliding groove is arranged in a through-type from one end of the impact part toward the impact surface to the end away from the impact surface, thereby reducing the probability that the impact surface cannot collide with the end surface of the impact part due to the influence of the damping force when the sliding part moves along the sliding groove;

[0028] 3. The diffusion effect of the sound-diffusing cavity is helpful to improve the tone of the impact sound, while also helping to maintain the timbre of the impact sound and reduce the probability of timbre distortion during the propagation of the impact sound.

DETAILED DESCRIPTION

[0036] The following is combined with Figures 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a key 1 with a special sound-generating structure. Figure 1 and Figure 2, A button 1 with a special sound - generating structure includes a carrier base 2, a pressing handle 3, and a reset member 4 for driving the pressing handle 3 to reset. The carrier base 2 is provided with a cavity 5, the pressing handle 3 is slidably arranged in the cavity 5, an impact part 6 is arranged in the cavity 5, and a sliding groove 7 is formed in the impact part 6 from the geometric center to the edge of the impact part 6.

[0038] Specifically, the pressing handle 3 includes a pressing part 31 and a sliding part 32. The pressing part 31 and the sliding part 32 are integrally formed. The sliding part 32 is slidably arranged in the sliding groove 7. An impact surface 8 is annularly arranged at the connection between the sliding part 32 and the pressing part 31. When a force is applied to the pressing part 31, the sliding part 32 follows the pressing part 31 and slides along the sliding groove 7. When the impact surface 8 comes into contact with the end face of the impact part 6, an impact sound will be emitted instantly.

[0039] Correspondingly, the carrier base 2 includes a base 21 and a cover 22. The cover 22 is snap - fitted to the base 21 to facilitate the disassembly or assembly of the cover 22 along the base 21. A through - hole 13 is formed in the upper surface of the cover 22 along the geometric center. The pressing part 31 movably passes through the through - hole 13 and extends outside the through - hole 13 for the user to press, so that the sliding part 32 can stably slide along the sliding groove 7.

[0040] At the same time, the cavity 5 is formed by recessing the upper surface of the base 21 in the thickness direction, and the impact part 6 is integrally formed with the base 21, reducing the probability of the impact part 6 falling off along the base 21. The contour of the sliding groove 7 is adapted to the contour of the sliding part 32, and can be structures such as a ring, a regular or irregular polygon, etc., which can be changed according to actual needs.

[0041] Moreover, preferably, in this embodiment, the "reset member 4" is selected as a reset spring. The reset spring is sleeved on the outer side wall of the impact part 6. At this time, the two ends of the reset spring respectively abut against the base 21 and the impact surface 8, realizing the purpose that when the force borne by the pressing part 31 disappears, the reset member 4 can quickly drive the sliding part 32 away from the impact part 6.

[0042] Therefore, when the user presses the pressing part 31, the sliding part 32 moves synchronously with the pressing part 31, so that the sliding part 32 can slide along the sliding groove 7 to drive the sliding part 32 to move towards the impact surface 8. When the impact surface 8 abuts against the end face of the impact part 6, an impact sound can be emitted instantly. The mechanical structure participating in the sound generation is relatively simple, emitting a clear HiFi (High - Fidelity) sound quality. This application uses the impact principle to generate sound. During the impact process between the impact surface 8 and the end face of the impact part 6, almost no mechanical loss occurs, which plays a positive guiding role in improving the consistency of the pressing sound generated by the user each time the button 1 is pressed.

[0043] Refer to Figure 2 andFigure 4 The tolerance fit relationship between the sliding groove 7 and the sliding part 32 is clearance fit, and the sliding groove 7 is arranged in a penetrating manner from one end of the impact part 6 facing the impact surface 8 to the end far from the impact surface 8.

[0044] Specifically, when a force is applied to the pressing part 31, it drives the sliding part 32 to slide along the sliding groove 7. During the process of the sliding part 32 sliding along the sliding groove 7, the air between the sliding part 32 and the bottom of the sliding groove 7 will be quickly compressed, thereby generating a damping force, so that the impact surface 8 cannot impact with the impact part 6.

[0045] Therefore, to solve the above problems, the sliding groove 7 is arranged in a penetrating manner from one end of the impact part 6 facing the impact surface 8 to the end far from the impact surface 8, so that both ends of the sliding groove 7 are in a communicating state. When the sliding part 32 slides towards the bottom of the sliding groove 7, the air between the sliding part 32 and the sliding groove 7 is quickly discharged, thus perfectly solving the above problems; at the same time, the tolerance fit relationship between the sliding groove 7 and the sliding part 32 is clearance fit, which enables the sliding part 32 to slide smoothly along the sliding groove 7, and is also beneficial to reducing the yaw of the sliding part 32 when sliding along the sliding groove 7, and improving the stability of the push handle 3 when moving along the bearing seat 2.

[0046] Refer to Figure 2 and Figure 3 A sound-dissipating cover 9 is arranged along the edge of the impact surface 8, and a sound-dissipating cavity 10 is formed between the sound-dissipating cover 9 and the sliding part 32.

[0047] Specifically, the sound-dissipating cover 9 and the sliding part 32 are integrally formed without secondary assembly. When the impact surface 8 impacts with the impact part 6 and generates an impact sound instantaneously, the impact sound quickly spreads along the sound-dissipating cavity 10. Through the diffusion effect of the sound-dissipating cavity 10, it is beneficial to improve the tone of the impact sound, and at the same time, it is also beneficial to maintain the timbre of the impact sound and reduce the probability of timbre distortion during the propagation of the impact sound.

[0048] At the same time, the sound-dissipating cover 9 is arranged to expand outward from the end close to the impact surface 8 to the end far from the impact surface 8, thus forming a conical shape. Because the sound-dissipating cover 9 is arranged to expand outward, the impact sound quickly conducts along the sound-dissipating cavity 10, which plays a positive guiding role in increasing the volume of the impact sound.

[0049] Correspondingly, the contour size of the impact part 6 is smaller than the contour size of the sound-dissipating cavity 10. First of all, it should be noted here that the cross-sectional shape of the impact part 6 is the same as the contour of the sound-dissipating cavity 10, but the size ratio is different. The "contour size" mentioned here refers to the cross-sectional area of the impact part 6 and the area enclosed by the contour of the sound-dissipating cavity 10.

[0050] Its function is that when the user presses the handle 3, the bearing part quickly moves along the sliding groove 7 towards the bottom of the sliding groove 7. At this time, the impact part 6 and the impact surface 8 quickly approach each other, and the air between the impact part 6 and the impact surface 8 is quickly compressed. Since the contour size of the impact part 6 is smaller than the contour size of the sound-dispersing cavity 10, the compressed air quickly disperses along the sound-dispersing cavity 10, reducing the probability of a delay occurring between the time when the user applies an action to the handle 3 and the time when the impact part 6 and the impact surface 8 collide due to the presence of compressed air between the impact part 6 and the impact surface 8.

[0051] Refer to Figure 2 and Figure 3 As shown in, on both sides where the sliding part 32 is along the sound-dispersing cover 9 away from the sound-dispersing cavity 10, an auxiliary sound-generating part 11 is provided. The auxiliary sound-generating part 11 is integrally formed with the sliding part 32. When the reset part 4 drives the handle 3 away from the bearing seat 2 and reaches the limit position, the auxiliary sound-generating part 11 abuts against the bearing seat 2.

[0052] Specifically, since the pressing part 31 movably passes through the through-hole 13 and the pressing part 31 is integrally formed with the sliding part 32, when the sliding part 32 is between the cover body 22 and the base 21, the auxiliary sound-generating part 11 is also between the cover body 22 and the base 21.

[0053] Therefore, when the reset part 4 drives the sliding part 32 away from the impact part 6 to reach the limit position, through the power provided by the reset part 4, the auxiliary sound-generating part 11 is driven to collide with the cover body 22. Thus, when the handle 3 is reset, a secondary impact sound is generated through the cooperation of the auxiliary sound-generating part 11 and the cover body 22, which is beneficial to improving the user's experience.

[0054] Correspondingly, the auxiliary sound-generating part 11 is arranged to be inclined downward from the end close to the sound-dispersing cover 9 to the end away from the sound-dispersing cover 9. Since the auxiliary sound-generating part 11 is arranged to be inclined downward, the contact area between the auxiliary sound-generating part 11 and the cover body 22 is reduced, thereby reducing the impact surface area between the auxiliary sound-generating part 11 and the bearing seat 2, which is beneficial to reducing the volume when the auxiliary sound-generating part 11 collides with the cover body 22. Through the above process, every time the user presses the pressing part 31 once, two impact sounds can be heard, which is beneficial to further improving the user's experience.

[0055] The implementation principle of the key 1 with a special sound-generating structure in the embodiment of the present application is as follows: when the user presses the pressing part 31, the sliding part 32 moves synchronously with the pressing part 31, so that the sliding part 32 can slide along the sliding groove 7 to drive the sliding part 32 to move toward the impact surface 8. When the impact surface 8 abuts against the end surface of the impact part 6, an impact sound can be emitted. The mechanical structure involved in the sound generation is relatively simple, and a crisp HiFi (High-Fidelity) sound quality is emitted. The present application utilizes the impact principle to generate sound. During the collision between the impact surface 8 and the impact part 6, almost no mechanical loss is generated, which plays a positive guiding role in improving the consistency of the pressing sound generated each time the user presses the key 1.

[0056] Reference Figure 5 In another embodiment, a magnetic block 12 is provided at one end of the sliding portion 32 away from the impact surface 8, thereby providing a necessary component for the magnetic axis button 1. It should be noted here that the working principle of the magnetic axis button 1 is to use the electromagnetic principle to achieve triggering through the induction of the Hall sensor and the magnetic block 12. When the button 1 is pressed, the magnetic block 12 approaches the Hall sensor and senses the change in the magnetic field, causing the Hall voltage to exceed the threshold and trigger the corresponding action, thereby realizing the input of the button 1, which is conducive to improving the sensitivity and stability of the button 1.

[0057] Therefore, since the magnetic block 12 is disposed in the sliding portion 32 of this embodiment, it can adapt to the assembly requirements of the magnetic axis button and has high practicality.

[0058] Correspondingly, refer to Figure 6 An end of the sliding portion 32 away from the impact surface 8 is provided with a mounting groove 14, and the mounting groove 14 is used to install the magnetic block 12. An undercut structure 15 is provided at the notch of the mounting groove 14, and the undercut structure 15 is used to block the magnetic block 12 in the mounting groove 14. Among them, the installation groove 14 is formed by an end of the sliding portion 32 away from the impact surface 8 and is recessed along the height direction of the sliding portion 32, so as to facilitate the stable installation of the magnetic block 12 in the sliding portion 32; at the same time, the inverted structure 15 is formed by bending the notch of the installation groove 14 toward the geometric center of the installation groove 14, and the spatial geometric area enclosed by the inverted structure 15 is smaller than the cross-sectional area of ​​the magnetic block 12. Therefore, when the magnetic block 12 is installed in the installation groove 14, the inverted structure 15 is used to block the magnetic block 12. Because the spatial geometric area enclosed by the inverted structure 15 is smaller than the cross-sectional area of ​​the magnetic block 12, the inverted structure 15 is used to lock the magnetic block 12 in the installation groove 14, thereby reducing the probability of the magnetic block 12 falling off or loosening along the installation groove 14.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
