Description

Technical Field

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

[0002] The working principle of the magnetic axis button is to utilize the electromagnetic principle and achieve triggering through the induction between the Hall sensor and the permanent magnet. When the button is pressed, the magnet approaches the Hall sensor, senses the change in the magnetic field, causes the Hall voltage to exceed the threshold, and triggers corresponding actions, thereby realizing the input of the button, which is beneficial to improving the sensitivity and stability of the button.

[0003] Compared with conventional mechanical buttons, the magnetic axis button can achieve signal transmission without contacting the base. In order to enhance the user experience, structures such as elastic pieces need to be used in cooperation with the base to produce sounds. When the user presses the button handle, the elastic piece located on the side wall or the ground of the button handle collides with the base, thereby generating a striking sound, which is beneficial to popularization and application.

[0004] However, in actual applications, when the user presses the button handle each time, the force applied to the button handle is inconsistent. As a result, the deformation degree of the elastic piece is different each time it is pressed, so that the sound emitted by the button is deviated each time, reducing the user experience, and there is room for improvement. Utility Model Content

[0005] In order to improve the sound quality balance of the metal - plastic impact sound generated when the user presses the button each time, this application provides a magnetic axis button with a special sound - generating structure.

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

[0007] A magnetic axis button with a special sound - generating structure includes a base, a button handle, and a reset member. The base is recessed in the thickness direction to form a cavity. The button handle is slidably disposed in the cavity. The reset member is disposed in the cavity and is used to reset the button handle. A magnetic block is disposed at one end of the button handle facing the cavity. A striking portion is disposed at the bottom of the cavity. When a force is applied to the button handle, the magnetic block moves with the button handle towards the striking portion, causing the magnetic block to strike the striking portion and emit an impact sound. When the force disappears, the reset member drives the button handle away from the striking portion.

[0008] By adopting the above technical solution, when the user applies force to the push handle, the push handle moves toward the striking part, so that the magnet follows the push handle to move toward the striking part, and at the moment when the magnet collides with the striking part, a collision sound is generated through the cooperation between the magnet and the striking part. Due to the material properties of the magnet itself, the sound produced by the collision between the magnet and the striking part is relatively crisp, and when the magnet collides with the striking part, the surface of the magnet abuts against the surface of the striking part. Each time the user presses the push handle, the extreme position of the movement of the push handle along the base is a fixed value, so that each time the user presses the push handle, the sound produced by the collision between the magnet and the striking part is relatively balanced.

[0009] Preferably, a mounting groove is provided at one end of the push handle facing the striking portion along the geometric center to the edge of the push handle, and the magnetic block is fastened in the mounting groove.

[0010] By adopting the above technical solution, since the magnetic block is fastened in the installation groove, the stability of the magnetic block when installed in the installation groove is improved, and the probability of the magnetic block loosening or falling off along the installation groove when the magnetic block is subjected to impact force is reduced.

[0011] Preferably, an undercut structure is provided at one end of the handle facing the striking portion, and the undercut structure is used to block the magnetic block in the mounting groove.

[0012] By adopting the above technical solution, the undercut structure is used to limit the installation position of the magnetic block in the installation groove, 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.

[0013] Preferably, an air relief groove is provided on the groove wall of the mounting groove along the bottom of the mounting groove to the end surface of the mounting groove.

[0014] By adopting the above technical solution, during the process of installing the magnetic block in the mounting groove, the air between the magnetic block and the bottom of the mounting groove is in a compressed state, so that the magnetic block cannot be accurately installed in the mounting groove. Therefore, the air between the magnetic block and the bottom of the mounting groove is discharged through the air discharge groove to reduce the position deviation of the magnetic block when it is installed in the mounting groove.

[0015] Preferably, the outer dimension of the striking portion is smaller than the circumferential dimension of the mounting groove.

[0016] By adopting the above technical solution, when the user applies an external force to the push handle to drive the magnet block carried by the push handle to move towards the striking part, the air between the striking part and the push handle is rapidly compressed. Since the external dimension of the striking part is smaller than the circumferential dimension of the mounting groove, there is a gap between the striking part and the mounting groove, facilitating the rapid discharge of air and reducing the probability of the situation where, at the moment when the magnet block abuts against the striking part, an air flow layer is formed between the magnet block and the striking part, resulting in the magnet block not being able to strike the striking part in time and causing a deviation in the sound emitted when the magnet block strikes the striking part.

[0017] Preferably, a guiding groove is provided on the base, and a guiding block is provided on the push handle. The guiding block is in sliding fit with the guiding groove.

[0018] By adopting the above technical solution, through the cooperation of the guiding groove and the guiding block, the movement path of the push handle when moving towards the base is defined, so as to reduce the yaw of the push handle when moving towards the base, which is beneficial to improving the user's pressing feel.

[0019] Preferably, a fixing cover is detachably provided on the base. The fixing cover is provided with a through hole penetrating along the thickness direction of the upper surface. The push handle is movably inserted into the through hole. When the reset member drives the push handle away from the striking part, the push handle abuts against the fixing cover.

[0020] By adopting the above technical solution, the limit position of the reset member driving the push handle away from the striking part is defined by the fixing cover, so that the position where the reset member finally stops driving the push handle away from the striking part is relatively fixed each time. At the same time, through the blocking effect of the fixing cover, the probability of the situation where the push handle detaches along the base when the reset member drives the push handle away from the striking part is reduced.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. At the moment when the magnet block strikes the striking part, through the cooperation of the magnet block and the striking part, an impact sound is generated. Due to the material characteristics of the magnet block itself, the sound emitted when the magnet block strikes the striking part is relatively clear. And when the magnet block strikes the striking part, the surface of the magnet block abuts against the surface of the striking part. The limit position of the push handle moving along the base is a fixed value when the user presses the push handle each time. Therefore, when the user presses the push handle each time, the sound emitted when the magnet block strikes the striking part is relatively balanced, which is beneficial to improving the sound quality balance of the metal-plastic impact sound generated when the user presses the button each time;

[0023] 2. Since the external dimension of the striking part is smaller than the circumferential dimension of the mounting groove, the probability of the situation where the magnet block cannot strike the striking part in time when the magnet block abuts against the striking part and causes a deviation in the sound emitted when the magnet block strikes the striking part is reduced;

[0024] 3. The guide part reduces the probability that when the handle carries the magnetic block and moves toward the striking part, the magnetic block cannot accurately collide with the striking part due to the position deviation between the magnetic block and the striking part.

[0031] The following is combined with Figures 1-4 This application is described in further detail.

[0032] The present application embodiment discloses a magnetic axis key 1 with a special sound-generating structure. Figure 1 and Figure 2 as well as Figure 4 A magnetic axis button 1 with a special sound-generating structure includes a base 2, a handle 3 and a reset member 4. The base 2 is recessed along the thickness direction to form a cavity 5. The handle 3 is slidably arranged in the cavity 5. The reset member 4 is arranged in the cavity 5. The reset member 4 is used to reset the handle 3. A magnetic block 6 is arranged at one end of the handle 3 facing the cavity 5. A striking part 7 is arranged at the bottom of the cavity 5. When a force is applied to the handle 3, the magnetic block 6 moves with the handle 3 toward the striking part 7. The magnetic block 6 hits the striking part 7 and makes a striking sound. When the force disappears, the reset member 4 drives the handle 3 away from the striking part 7.

[0033] Specifically, a sliding cylinder 51 is arranged along the geometric center of the cavity 5. The base 2 and the sliding cylinder 51 are integrally formed by injection molding. The sliding cylinder 51 is arranged along the vertical direction of the cavity 5, and the inside of the sliding cylinder 51 is hollow. At the same time, the push handle 3 includes a pressing part 31 and a bearing part 32, which are integrally formed. The pressing part 31 is used for the user to apply a force on it. The contour of the bearing part 32 is adapted to the inner contour of the sliding cylinder 51. Therefore, the contour of the bearing part 32 can be changed according to the inner shape of the sliding cylinder 51, such as a circular shape, a regular or irregular polygon structure, etc., so that the bearing part 32 can slide stably along the sliding cylinder 51.

[0034] Furthermore, for the reset member 4, in this embodiment, preferably, the reset member 4 is a reset spring, and the reset spring is sleeved on the outer side wall of the sliding cylinder 51. When the bearing part 32 is located in the sliding cylinder 51, both ends of the reset spring are respectively abutted against the bottom of the cavity 5 and the end face of the bearing part 32.

[0035] At the same time, the striking part 7 is located at the bottom of the sliding cylinder 51, and the magnet 6 is located at one end of the bearing part 32 facing the striking part 7 located at the bottom of the sliding cylinder 51. Therefore, when the operator applies a force on the pressing part 31, the bearing part 32 bears the magnet 6 and moves towards the striking part 7. At this time, the reset member 4 is in a compressed state. When the magnet 6 collides with the striking part 7 in an instant, through the cooperation of the magnet 6 and the striking part 7, an impact sound is generated. Due to the material characteristics of the magnet 6 itself, and the base 2 is made of plastic material by injection molding, the sound generated by the collision of the magnet 6 and the striking part 7 is relatively clear, and can effectively simulate a clear HiFi (High Fidelity) sound effect. And when the user presses the push handle 3 each time, the limit position of the push handle 3 moving along the base 2 is a fixed value. Therefore, when the user presses the push handle 3 each time, the sound generated by the collision of the magnet 6 and the striking part 7 is relatively balanced, which is beneficial to improving the user experience.

[0036] On the other hand, referring to Figure 1 and Figure 2 , a fixing cover 13 is detachably arranged on the base 2. The fixing cover 13 is provided with a through hole 14 penetrating along the thickness direction of the upper surface. The push handle 3 is movably inserted into the through hole 14. When the reset member 4 drives the push handle 3 away from the striking part 7, the push handle 3 abuts against the fixing cover 13.

[0037] Specifically, a buckle 131 is provided at one end of the fixed cover 13 that abuts against the base 2, and a buckling position 21 is provided on the base 2. At the same time, an extension 321 is provided on the outer circumferential side wall of the bearing part 32. Therefore, when the reset member 4 is sleeved on the sliding cylinder 51 and the bearing part 32 is located inside the sliding cylinder 51, the push handle 3 is covered by the fixed cover 13. At this time, the pressing part 31 of the push handle 3 passes through the through hole 14 and extends to the outside of the cavity 5. At this time, the buckle 131 and the buckling position 21 are buckled with each other, and the push handle 3 is subjected to the reset force applied by the reset member 4, driving the bearing part 32 away from the striking part 7. When the extension 321 abuts against the fixed cover 13, it is the limit distance that the reset member 4 can drive the push handle 3 to move along the sliding cylinder 51.

[0038] Therefore, through the cooperation of the buckle 131 and the buckling position, it is convenient to assemble and disassemble the push handle 3 and the base 2. The fixed cover 13 limits the limit position where the reset member 4 drives the push handle 3 away from the striking part 7, so that the position where the reset member 4 finally stops driving the push handle 3 away from the striking part 7 is relatively fixed each time. At the same time, through the blocking effect of the fixed cover 13, when the reset member 4 drives the push handle 3 away from the striking part 7, the probability of the push handle 3 detaching along the base 2 is reduced.

[0039] Refer to Figure 2 and Figure 3 , an installation groove 8 is formed at one end of the push handle 3 facing the striking part 7 from the geometric center of the push handle 3 to the edge, and the magnet 6 is fastened in the installation groove 8.

[0040] Specifically, the installation groove 8 is formed by recessing from the end face of the bearing part 32 facing the striking part 7 along the height direction of the bearing part 32. The shape and size of the installation groove 8 need to be set according to the shape and size of the magnet 6 to meet the purpose of fastening the magnet 6 in the installation groove 8.

[0041] Correspondingly, an air release groove is formed on the groove wall of the installation groove 8 from the bottom of the installation groove 8 to the end face of the installation groove 8. Its function is: during the process of installing the magnet 6 in the installation groove 8, the air between the magnet 6 and the bottom of the installation groove 8 is in a compressed state, so that the magnet 6 cannot be accurately installed in the installation groove 8. Therefore, the air between the magnet 6 and the bottom of the installation groove 8 is released through the air release groove to reduce the position deviation when the magnet 6 is installed in the installation groove 8.

[0042] Refer to Figure 3 and Figure 4 , the groove depth of the installation groove 8 is greater than the thickness of the magnet 6, so as to form a guiding part 9, and the external contour of the striking part 7 is the same as the contour of the guiding part 9.

[0043] Specifically, the striking part 7 is formed by the bottom of the sliding cylinder 51 protruding toward the barrel mouth of the sliding cylinder 51, and the striking part 7 is integrally formed with the base 2, thereby reducing the probability of the striking part 7 falling off along the sliding cylinder 51 as the number of collisions of the magnetic block 6 with the striking part 7 increases.

[0044] Therefore, the movement path of the magnetic block 6 toward the striking part 7 is limited by the guide part 9, thereby reducing the probability of the magnetic block 6 being unable to accurately collide with the striking part 7 due to the deviation in the positions of the magnetic block 6 and the striking part 7 when the handle 3 carries the magnetic block 6 to move toward the striking part 7, resulting in the impact sound produced by the cooperation between the striking part 7 and the magnetic block 6 not meeting the design requirements.

[0045] Correspondingly, the outer dimension of the striking part 7 is smaller than the circumferential dimension of the mounting groove 8, so that the dimension of the striking part 7 is smaller than the dimension of the mounting groove 8, which can bring the following beneficial effects: when the user applies external force to the button handle 3 to drive the button handle 3 to carry the magnet 6 to move toward the striking part 7, the air between the striking part 7 and the button handle 3 is rapidly compressed, because the outer dimension of the striking part 7 is smaller than the circumferential dimension of the mounting groove 8, so that there is a gap between the striking part 7 and the mounting groove 8 to facilitate the rapid discharge of air, thereby reducing the probability of an air flow layer being formed between the magnet 6 and the striking part 7 at the moment when the magnet 6 abuts against the striking part 7, resulting in the magnet 6 being unable to collide with the striking part 7 in time, and causing a deviation in the sound produced by the collision between the magnet 6 and the striking part 7; at the same time, at the moment when the magnet 6 collides with the striking part 7, the impact sound produced is propagated in the narrow space between the striking part 7 and the mounting groove 8, which is beneficial to increase the volume of the impact sound.

[0046] In another embodiment, referring to Figure 5 , an inverted buckle structure 16 is provided at one end of the handle 3 facing the striking portion 7, and the inverted buckle structure 16 is used to block the magnetic block 6 in the installation groove 8. The inverted buckle structure 16 is formed by bending the end of the handle 3 facing the striking portion 7 toward the geometric center of the installation groove 8, and the geometric area of ​​the space enclosed by the inverted buckle structure 16 is smaller than the cross-sectional area of ​​the magnetic block 6. Therefore, when the magnetic block 6 is installed in the installation groove 8, the inverted buckle structure 16 is used to block the magnetic block 6. Since the geometric area of ​​the space enclosed by the inverted buckle structure 16 is smaller than the cross-sectional area of ​​the magnetic block 6, the inverted buckle structure 16 is used to lock the magnetic block 6 in the installation groove 8, thereby reducing the probability of the magnetic block 6 falling off or loosening along the installation groove 8.

[0047] On the other hand, a cavity 15 is provided at one end of the base 2 away from the striking part 7. As mentioned above, the base 2 is integrally formed of a plastic material by injection molding. When the magnetic block 6 collides with the striking part 7, a chamber for sound wave transmission is formed through the cavity 15, which facilitates the conduction of the impact sound and is beneficial to further enhance the crispness of the impact sound emitted when the magnetic block 6 collides with the striking part 7.

[0048] Reference Figure 2 Or Figure 4 On the base 2, a guiding groove 11 is provided, and on the pressing handle 3, a guiding block 12 is provided. The guiding block 12 is in sliding fit with the guiding groove 11.

[0049] Specifically, the guiding groove 11 is formed by opening from the side wall of the cavity 5 along the bottom of the cavity 5 to the end face of the cavity 5, and guiding grooves 11 are opened from the geometric center of the cavity 5 to both side walls of the cavity 5.

[0050] Correspondingly, the guiding blocks 12 are located on both side walls of the extension part 321 in the width direction. Therefore, through the cooperation of the guiding groove 11 and the guiding block 12, the movement path of the pressing handle 3 when moving towards the base 2 is limited, so as to reduce the yaw of the pressing handle 3 when moving towards the base 2, which is beneficial to improving the user's pressing feel.

[0051] The implementation principle of the magnetic axis key 1 with a special sound - generating structure in the embodiment of the present application is as follows: when a user applies a force to the pressing handle 3, the pressing handle 3 moves towards the striking part 7, so that the magnetic block 6 follows the pressing handle 3 to move towards the striking part 7. When the magnetic block 6 collides with the striking part 7 at a moment, through the cooperation of the magnetic block 6 and the striking part 7, an impact sound is generated. Due to the material characteristics of the magnetic block 6 itself, and the base 2 is made of plastic by injection molding, the sound generated by the collision of the magnetic block 6 and the striking part 7 is relatively clear, and can effectively simulate a clear HiFi (High Fidelity) sound effect. Moreover, when the magnetic block 6 collides with the striking part 7, the surface of the magnetic block 6 abuts against the surface of the striking part 7. When the user presses the pressing handle 3 each time, the limit position of the pressing handle 3 moving along the base 2 is a fixed value. Therefore, when the user presses the pressing handle 3 each time, the sound generated by the collision of the magnetic block 6 and the striking part 7 is relatively balanced, which is beneficial to improving the sound quality balance of the metal - to - plastic impact sound generated when the user presses the key each time.

[0052] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
