Description

[0001] This application claims priority to Chinese Patent Application No. 202110230071.0, filed on March 2, 2021, entitled “An electronic device and a method for manufacturing the same,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal technology, and in particular to an electronic device. Background Technology

[0003] A laptop is a small, portable terminal device. Among the hardware components of a laptop, the keyboard is one of the most important input ports, and the performance of the keyboard greatly affects the user experience.

[0004] Currently, in order to balance the uneven force distribution on large keys (such as the shift key, enter key, space key, etc.) in laptop keyboards, a pair of linkbars are often installed under the keycaps of large keys. The linkbars are usually made of stainless steel, and the two ends of the linkbars are rotatably connected to the mounting slots (i.e., beaks) on the keyboard base plate. The linkbars can play a role in transmitting force, ensuring that the keycaps are evenly stressed when they are struck, so that the entire plane of the keycaps moves almost simultaneously.

[0005] However, during keyboard typing, noise is generated due to the collision between the stabilizer bar and the mounting slot on the keyboard base plate. In addition, when the speakers inside the laptop emit sound, resonance easily occurs between the stabilizer bar and the keyboard base plate, ultimately resulting in significant keyboard noise during use. Therefore, overcoming the keyboard noise problem has become an urgent issue for laptops to address. Summary of the Invention

[0055] In an embodiment of the present application, a laptop is taken as an example of the electronic device.

[0056] Figure 1 A perspective structural schematic diagram of the laptop is shown in FIG. 1. Figure 1As shown, the electronic device 100 can include a display screen 10 and a host body 20, the display screen 10 and the host body 20 can be rotatably connected, for example, the display screen 10 and the host body 20 can be connected through a rotating shaft; or, the display screen 10 and the host body 20 can be rotatably connected through a hinge structure; or, in some examples, the display screen 10 and the host body 20 can be independent devices, for example, the display screen 10 and the host body 20 can be detachable, in use, the display screen 10 is placed on the host body 20, and after use, the display screen 10 and the host body 20 can be separated from each other.

[0057] It should be noted that in order to realize the display effect of the display screen 10, the display screen 10 and the host body 20 are electrically connected, for example, the display screen 10 and the host body 20 can be electrically connected through contacts, or the display screen 10 and the host body 20 are electrically connected through a flexible printed circuit (FPC), or the display screen 10 and the host body 20 are electrically connected through a wire, in addition, the display screen 10 and the host body 20 can also be wirelessly connected through wireless signals.

[0058] Referring to Figure 1 As shown, in order to realize the input of the electronic device, the electronic device 100 can further include a keyboard device 30, the keyboard device 30 can be arranged on the host body 20, for example, as Figure 2 As shown, the host body 20 has a mounting portion 21, the keyboard assembly is arranged on the mounting portion 21 of the host body 20, the keyboard device 30 is electrically connected with the control unit in the host body 20, and the keyboard device 30 serves as an input device of the electronic device 100.

[0059] Referring to Figure 1 As shown, in order to realize the external sound playing of the electronic device 100, a loudspeaker 40 is often arranged in the host body 20, so that the user can listen to the sound emitted by the electronic device 100 through the external earphone or through the built-in loudspeaker 40. Among them, the design position of the loudspeaker 40 needs to be set according to the specific working condition, in some examples of the present application, the loudspeaker 40 is arranged close to the outer edge of the keyboard device 30, it should be noted that when the loudspeaker 40 is arranged close to the outer edge of the keyboard device 30, "close" specifically means that when the loudspeaker 40 is arranged on the host body 20, the loudspeaker 40 is closer to the outer edge of the keyboard device 30 than the center of the keyboard device 30 on the host body 20.

[0060] For example, as Figure 1As shown, the speaker 40 can be two, symmetrically arranged at the lower edge of the keyboard device 30. Of course, the speaker 40 can also be arranged at the upper edge or left and right side edges of the keyboard device 30. The sound outlet (not shown in the figure) of the electronic device 100 can be arranged corresponding to the position of the speaker 40, or opened at the left and right side edges of the main body 20.

[0061] Figure 2 The structure of the keyboard device 30 is shown, referring to Figure 2 As shown, the keyboard device 30 can include a keyboard substrate 32 and a plurality of keys 31 arranged on the keyboard substrate 32. The types of the keys 31 can refer to Figure 2 The structure, for example, the plurality of keys 31 include numeric keys, function keys (such as Delete key, Insert key, etc.), and letter keys, etc. According to the size of the keys 31, they can be divided into single keys and multiple keys. The single key is a square key on the keyboard (the structure of the upper surface of the keyboard is similar to a square), for example, the keys corresponding to each letter and each number. The multiple key is a key other than the single key. The multiple key can be a long strip, for example, the length of the multiple key is greater than the width. Referring to Figure 2 As shown, some keys 31, for example, single keys, are small in size. For example, in one keyboard device 30 of the present application, the length and width of the single key are both 1.6 cm. Some keys 31, for example, multiple keys (such as space key 31a, Enter key 31b, and Shift key 31c, etc.), are larger in size than the single key. For example, in one keyboard device 30 of the present application, the length and width of a part of the multiple keys are 1.8 cm and 1.6 cm respectively, and the length and width of another part of the multiple keys are 10.2 cm and 1.6 cm respectively, etc.

[0062] In order to realize the input function of the keys 31, referring to Figure 2 As shown, the keyboard substrate 32 is provided with a contact 32a. When the key 31 is pressed, the contact 32a is triggered to realize the input function.

[0063] Figure 3 A schematic view of the disassembly of the Enter key 31b, which is one of the multiple keys of the electronic device 100, Figure 4 A schematic view of the disassembly of the Enter key 31b in Figure 3 It should be noted that, Figure 4 The keyboard substrate 32 shown is the part of the keyboard substrate 32 corresponding to one key 31, that is, Figure 4 Only part of the keyboard substrate 32 is shown in Figure 4 The specific disassembly of the Enter key 31b in Figure 2 The specific disassembly of the Enter key 31b in

[0064] Referring toFigure 4 As shown in FIG. 1, each key 31 can include a key cap 311 and at least one spring assembly 312, for example. Figure 4 In some examples, the number of spring assemblies 312 can be one or more than two. The spring assembly 312 is connected to the key cap 311 and the keyboard substrate 32, and is used to drive the key cap 311 to reset after the finger leaves the key cap 311 after pressing the key cap 311.

[0065] In the embodiments of the present application, as shown in FIG. 1, Figure 4 As shown in FIG. 1, each spring assembly 312 includes an upper scissor leg 3121 and a lower scissor leg 3122. The upper scissor leg 3121 and the lower scissor leg 3122 are cross-connected and rotatable. One end of the upper scissor leg 3121 and the lower scissor leg 3122 is connected to the keyboard substrate 32, and the other end of the upper scissor leg 3121 and the lower scissor leg 3122 is connected to the key cap 311. The upper scissor leg 3121 and the lower scissor leg 3122 have elasticity. When the end of the upper scissor leg 3121 and the lower scissor leg 3122 connected to the key cap 311 is compressed, the upper scissor leg 3121 and the lower scissor leg 3122 reset the key cap 311 by relying on the elastic force of the upper scissor leg 3121 and the lower scissor leg 3122 after the external force is removed.

[0066] In the embodiments of the present application, the material of the upper scissor leg 3121 and the lower scissor leg 3122 can be plastic. The upper scissor leg 3121 and the lower scissor leg 3122 can be rotatably connected through a rotating shaft.

[0067] As shown in FIG. 1, the upper scissor leg 3121 and the lower scissor leg 3122 can be connected to the keyboard substrate 32 through a clamping manner. For example, as shown in FIG. 1, Figure 4 As shown in FIG. 1, the keyboard substrate 32 is provided with a clamping piece 322, and the upper scissor leg 3121 and the lower scissor leg 3122 are provided with buckles (not shown). The upper scissor leg 3121 and the lower scissor leg 3122 are respectively connected to the keyboard substrate 32 through the buckles and the clamping piece 322.

[0068] The upper scissor leg 3121 and the lower scissor leg 3122 can also be connected to the key cap 311 through a clamping manner. Of course, in some examples, the upper scissor leg 3121 and the lower scissor leg 3122 can abut against the key cap 311. For example, one end of the upper scissor leg 3121 and the lower scissor leg 3122 abuts against the back surface 3113 of the key cap 311 (see FIG. 2). Figure 6

[0069] In the embodiments of the present application, in order to balance the stress of the large-size key 31 (such as the space key 31a, the Enter key 31b, and the Shift key 31c) during use, as shown in FIG. 1, Figure 4 ​As shown, at least part of the plurality of keys 31 further comprises at least one balance bar 33, for example, Figure 2 The keys 31 with large sizes, such as the space key 31a, the Enter key 31b, the Shift key 31c, etc., further comprise at least one balance bar 33, or each key 31 can comprise at least one balance bar 33 when the size of each key 31 is large.

[0070] In the embodiments of the present application, referring to Figure 4 As shown, the number of balance bars 33 is two, of course, in some other examples, the number of balance bars 33 can also be one, or the number of balance bars 33 can also be three, and the following embodiments will be described by taking one key 31 corresponding to two balance bars 33 as an example.

[0071] The keyboard substrate 32 has at least two opposite assembly side walls 321, referring to Figure 4 As shown, the keyboard substrate 32 has two opposite assembly side walls 321, and the two assembly side walls 321 are respectively provided with assembly grooves 321a and 321b, and the two ends of each balance bar 33 are respectively arranged in the assembly grooves 321a and 321b, for example, the first end of the balance bar 33 has a hook 331a, and the hook 331a is rotatably connected in the assembly groove 321a (see Figure 5 As shown), the second end of the balance bar 33 has a hook 331b, and the hook 331b is rotatably connected in the assembly groove 321b. The balance bar 33 can rotate longitudinally around the assembly grooves 321a and 321b. In order to ensure that the balance bar 33 is not blocked during rotation, the assembly side wall 321 is generally at an angle with the keyboard substrate 32, for example, the assembly side wall 321 is at an angle of 90° (see Figure 4 As shown), 60°, 45°, etc. with the keyboard substrate 32.

[0072] Referring to Figure 4 As shown, in some embodiments, a through groove 325 can also be provided on the keyboard substrate 32 close to the assembly groove 321a (321b), and the through groove 325 is in communication with the assembly groove 321a (321b). When the balance bar 33 rotates longitudinally around the assembly grooves 321a and 321b, due to the existence of the through groove 325, the hooks 331a and 331b can avoid rubbing or impacting with the keyboard substrate 32, thereby reducing the generation of noise.

[0073] Referring to Figure 5As shown, when the number of the balance bars 33 corresponding to one keycap 311 is two, the hooks 331a of the first ends of the two balance bars 33 respectively extend into two assembly grooves 321a, wherein the two assembly grooves 321a can be separated by a partition plate 321c, so that the hooks 331a of the first ends of the two balance bars 33 do not interfere or collide with each other when rotating in the assembly grooves 321a. The hooks 331b of the second ends of the two balance bars 33 respectively extend into two assembly grooves 321b. The two assembly grooves 321b can be separated by the partition plate 321c, or, in some examples, the partition plate 321c can not be arranged between the two assembly grooves 321a and the two assembly grooves 321b, and the two assembly grooves 321a are communicated with each other, and the two assembly grooves 321b are communicated with each other.

[0074] In the embodiments of the present application, referring to Figure 5 As shown, the keyboard substrate 32 can include a metal bottom plate 324 and a circuit board 323, which can be a printed circuit board (PCB), or the circuit board 323 can be a flexible printed circuit (FPC), wherein the metal bottom plate 324 plays a supporting role, Figure 2 The contact points 32a in the circuit board 323 are arranged on the circuit board 323, and the contact points 32a are electrically connected with the circuit board 323. The metal bottom plate 324 is provided with a protruding assembly side wall 321 (see Figure 4 ), and the assembly side wall 321 is provided with an opening to form an assembly groove 321a (321b). Wherein, the assembly side wall 321 can be integrally formed with the metal bottom plate 324, or the assembly side wall 321 can be fixed on the metal bottom plate 324 by clamping, welding or fasteners and the like.

[0075] In some examples, the keyboard substrate 32 can further include a shielding layer (not shown), which can be located on the circuit board 323 and play a shielding role for the wiring on the circuit board 323.

[0076] Referring to Figure 6 As shown, the balance bar 33 is rotatably connected with the keycap 311, for example, the back surface 3113 of the keycap 311 is provided with a clamping block 3111, and two oppositely arranged clamping blocks 3111 define a clamping groove 3112, the balance bar 33 is clamped into the clamping groove 3112, and the balance bar 33 can rotate in the clamping groove 3112, referring to Figure 6 As shown, each balance bar 33 corresponds to two clamping grooves 3112 arranged on the back surface of the keycap 311.

[0077] Of course, in some examples, the number of card slots 3112 includes but is not limited to two. By setting the balance bar 33 so that the keycap 311 is forced at a certain position, the entire keycap 311 can be lowered as a whole, ensuring that the keycap 311 is evenly stressed when in use.

[0078] Wherein, the keycap 311 can be a plastic keycap, and the clamping block 3111 and the keycap 311 can be integrally formed, or the clamping block 3111 and the keycap 311 can be connected by welding or clamping.

[0079] In some embodiments, the cross-sectional dimension of the hook 331a at both ends can be different, and the cross-sectional dimension of the inner end of the hook 331a (connected to one end of the balance bar 33) is greater than that of the outer end (the other end). For example, as shown in Figure 7 In some embodiments, in order to make the two ends of the balance bar 33 more easily assembled with the assembly slot 321a (321b), the hook 331a and the hook 331a at both ends of the balance bar 33 can also be tapered, and the large end of the tapered shape is connected to the balance bar 33, that is, the outer diameter of the hook 331a and the hook 331a gradually decreases from the end connected to the balance bar 33 to the other end. In this way, on the one hand, it is convenient for the hook 331a and the hook 331a at both ends of the balance bar 33 to extend into the assembly slot 321a and the assembly slot 321b, and on the other hand, when the hook 331a and the hook 331a are tapered, the contact area between the hook 331a and the hook 331b and the assembly slot 321a and the assembly slot 321b is reduced, so that resonance occurs, or the hook 331a and the hook 331b at both ends of the balance bar 33 and the assembly slot 321a and the assembly slot 321b are reduced when the key 31 is struck and collided, thereby achieving the purpose of reducing noise.

[0080] It should be noted that in the embodiments of the present application, the outer diameter of the hook 331a and the hook 331b at both ends of the balance bar 33 can also be set to a constant outer diameter, and the outer diameter of the hook 331a and the hook 331b at both ends of the balance bar 33 is smaller than the outer diameter of the balance bar 33, for example, the outer diameter of the hook 331a and the hook 331b at both ends of the balance bar 33 directly decreases from the end of the balance bar 33 to a constant outer diameter.

[0081] In some schemes, in order to ensure that the balance bar 33 is wear-resistant and has a certain strength, the material of the balance bar 33 is generally stainless steel material, and the metal bottom plate 324 and the assembly side wall 321 are also metal. When the two ends of the balance bar 33 are rotatably arranged in the assembly slot 321a and the assembly slot 321b, during use, as the key 31 moves up and down, the balance bar 33 rotates around the two ends (for example, see Figure 4The first end hook 331a and the second end hook 331b of the middle balance bar 33 rotate, so that when the knock button 31 is knocked, the two ends of the balance bar 33 are easy to collide with the groove wall of the assembly groove 321a (321b), and noise is generated.

[0082] In addition, since the host body 20 of the electronic device 100 is provided with the loudspeaker 40, the loudspeaker 40 is often close to the outer edge of the keyboard device 30, for example, as shown in the figure, Figure 3 two loudspeakers 40 are respectively located on the two sides below the keyboard device 30, and are arranged close to the keyboard device 30, so that when the loudspeaker 40 works, the sound emitted is easy to resonate with the balance bar 33 made of stainless steel, the metal bottom plate 324 and the assembly side wall 321, and during the resonance process, since the balance bar 33 is movable between the assembly groove 321a and the groove wall, the balance bar 33 collides with the groove wall of the assembly groove 321a during the resonance, noise is generated, and finally the noise of the electronic device 100 is large, which greatly affects the use of the user and reduces the satisfaction of the user to the electronic device 100.

[0083] At present, whether it is a mobile phone, a tablet, a personal computer or a television product, in order to improve the sound effect, it has been developed from a single loudspeaker to a double loudspeaker, and even multiple loudspeakers, and the power of the loudspeaker is getting larger and larger, but the loudspeaker itself is mostly still of the voice coil type. There is a large vibration in the vibration direction of the voice coil of the loudspeaker, and the vibration will be directly transmitted to the whole machine. There are many movable parts in the whole machine, such as a camera, a keyboard, a plug-in part, a shell, etc. These movable parts will appear forced vibration when the loudspeaker works, thereby emitting various abnormal noises, which will cause the user to obviously feel the noise in subject, the experience will obviously decrease, thereby affecting the quality of the whole product.

[0084] The basic way to control the resonance noise of the whole machine is first to control the noise source, and second to control the noise propagation and noise reception.

[0085] The present application is to control the vibration body from the noise propagation control, for example, in a notebook computer, the largest vibration body is the keyboard device 30, and there are a large number of resonant components in the keyboard device 30, and the position where the obvious noise is generated is the impact between the balance bar 33 and the assembly side wall 321 (i.e. the hawk mouth). By reducing the impact between the balance bar 33 and the assembly side wall 321, the noise generated by the keyboard device 30 can be obviously reduced. However, the balance bar 33 and the assembly side wall 321 are movable parts and cannot be fixed. The keycap 311 needs to drive the balance bar 33 to achieve the up-down movement of the knock button 31.

[0086] One solution is to wrap the stabilizer bar 33 with a flexible material for shock absorption and protection. For example, thermoplastic tubes can be fitted onto both ends of the stabilizer bar 33. However, the length of the thermoplastic tubes fitted onto the stabilizer bar 33 is limited, and assembly cannot be continuous, often requiring manual installation, resulting in low automation. Furthermore, the thermoplastic tubes need to be bent after being fitted onto the stabilizer bar 33. Figure 6 The shape of the balance bar 33 shown in the figure creates stress concentration at the bend, which can easily cause deformation, breakage, burrs, and looseness between the thermoplastic tube and the balance bar 33.

[0087] Another solution is to add shock-absorbing protection at the points where the mounting slots 321a and 321b collide with the balance bar 33. For example, a buffer layer (such as foam, Mylar film, etc.) can be added at the contact points between the two ends of the balance bar 33 and the mounting slots 321a and 321b. However, this reduces the gap between the two ends of the balance bar 33 and the mounting slots 321a and 321b, resulting in the key 31 moving unsmoothly up and down. Users need to press the keyboard with a large force or the key 31 becomes unresponsive. In addition, the process integration of adding a buffer layer between the two ends of the balance bar 33 and the mounting slots 321a and 321b is low, often requiring manual completion, which is inefficient and costly.

[0088] The third solution is to assemble sidewall 321 (see...) Figure 4 The assembly grooves 321a and 321b are made of plastic, which reduces the collision noise between the balance bar 33 and the plastic when the balance bar 33 moves up and down, thus playing a role in shock absorption and noise reduction when playing music or videos. However, since the metal base plate 324 is metal and the assembly side wall 321 is plastic, when the two are injection molded together, the metal base plate 324 and the assembly side wall 321 have a weaker bonding force at the interface due to the different materials. After the balance bar 33 moves up and down with the keycap 311, it is easy for delamination to occur between the assembly side wall 321 and the metal base plate 324.

[0089] To address the above problems, in some embodiments, see [reference] Figure 8 As shown, it also includes at least one magnetic part 50, wherein the magnetic part 50 may be located on at least one of the balance bar 33 and the keyboard base plate 32. For example, the magnetic part 50 is provided on the balance bar 33, or, as shown... Figure 8 As shown, a magnetic part 50 is provided on the side of the keyboard base plate 32 facing away from the balance bar 33, or a magnetic part 50 is provided on both the balance bar 33 and the keyboard base plate 32.

[0090] When the magnetic part 50 is arranged on the balance bar 33, the magnetic part 50 can be used to attract or repel the keyboard substrate 32, or the magnetic part 50 can be used to attract part of the keyboard substrate 32 (for example, the inner wall top end of the assembly groove 321a) and repel part of the keyboard substrate 32 (for example, the inner wall bottom end of the assembly groove 321a). When the magnetic part 50 is arranged on the keyboard substrate 32, part of the magnetic part 50 can be used to attract the two ends of the balance bar 33 (i.e. the end portions including at least the hooks 331a and 331b), and part of the magnetic part 50 can be used to repel the two ends of the balance bar 33. When the magnetic part 50 is arranged on both the balance bar 33 and the keyboard substrate 32, the magnetic part 50 on the balance bar 33 can attract or repel the magnetic part 50 on the keyboard substrate 32, or the magnetic part 50 on the balance bar 33 can attract part of the magnetic part 50 on the keyboard substrate 32 and repel the rest of the magnetic part 50 on the keyboard substrate 32.

[0091] By using the principle of magnetic force, a constraint relationship is formed at the contact position of the balance bar 33 and the keyboard substrate 32, the free vibration of the balance bar 33 is limited by using the attraction or repulsion between the two components, so that the balance bar 33 is not easy to produce resonance and forced vibration, but the movement stroke of the keycap 311 is not limited. Therefore, in the embodiment of the present application, the purpose of reducing vibration and noise of the keyboard can be achieved, the problem of keyboard noise can be improved, and the problem of large noise of the keyboard during use due to the collision and resonance between the assembly groove 321a (321b) of the balance bar 33 and the keyboard substrate 32 can be solved. In addition, the above design will not affect the user's experience.

[0092] In addition to adding the magnetic part 50, the structure of the keyboard substrate 32, the rebound assembly 312 and the keycap 311 in the keyboard device 30 is not changed, and the resistance of the keycap 311 when typing the keycap 311 is not greatly changed, so that the purpose of reducing vibration and noise is achieved without changing the structure of the keyboard device 30. In addition, the related process and assembly of the magnetic part 50 can be continuously produced and assembled, improving the efficiency of assembly and production.

[0093] The magnetic part 50 can be magnetic glue, magnetic sheet, magnetic film, magnetic plating layer, magnet or magnetic powder, etc. The arrangement mode of the magnetic part 50 includes plating, coating, doping, manual assembly, mechanical assembly, etc.

[0094] The plating magnetic material can be, but is not limited to, ferrite, neodymium iron boron, samarium cobalt alloy, etc., and the plating magnetic method includes, but is not limited to, atomic layer reaction plating film, magnetron sputtering, electron beam evaporation, etc.

[0095] The combination between the magnetic sheet and the keyboard substrate 32 or the balance bar 33 includes, but is not limited to, welding, glue spraying, self-attaching glue, etc.

[0096] The magnetic layer plated on the surface of the balance bar 33 and the keyboard substrate 32 has the advantages that the film-base bonding force between the metal or metalized layer and the stainless steel is higher than that between the polymer layer and the stainless steel, the plating process is atomic deposition on the stainless steel balance bar, which can ensure that the plated layer is thin and uniform, and no additional parts are generated, and the original installation process can remain unchanged.

[0097] In some embodiments of the present application, the magnetic part 50 can be arranged on the corresponding area of the keyboard substrate 32 and the two ends of the balance bar 33. For example, as shown in Figure 8 In general, the balance bar 33 itself is a magnetically attractive stainless steel, and in special cases, if the balance bar 33 itself does not have magnetism, magnetic powder or other magnetic materials can be added to the balance bar 33. In this way, the magnetic part 50 is attracted or repelled to the two ends of the balance bar 33, and when the balance bar 33 moves up and down, the two ends of the balance bar 33 and the assembly groove 321a (321b) of the keyboard substrate 32 form a constraint relationship (for example, the magnetic force blocks the movement of the balance bar 33), thereby reducing or avoiding the collision between the two ends of the balance bar 33 and the inner wall of the assembly groove 321a (321b), and further reducing or avoiding the noise generated by the collision, thereby improving the problem of relatively large noise.

[0098] It can be understood that, Figure 8 As shown in the figure, the magnetic part 50 is arranged on the side of the keyboard substrate 32 away from the balance bar 33. Of course, in other embodiments of the present application, the magnetic part 50 can also be arranged on the side of the keyboard substrate 32 facing the balance bar 33.

[0099] Alternatively, the magnetic part 50 can also be inlaid in the keyboard substrate 32, for example, as shown in Figure 9 As shown in the figure, the magnetic part 50 can be arranged in the through groove 325, so that the magnetic part 50 is attracted or repelled to the two ends of the balance bar 33, and the assembly groove 321a (321b) between the two ends of the balance bar 33 and the keyboard substrate 32 forms a constraint relationship, thereby improving the problem of relatively large noise. Moreover, the magnetic part 50 is arranged in the through groove 325, so that the magnetic part 50 does not affect the surrounding structure, and does not increase the thickness of the entire keyboard structure.

[0100] It should be noted that the magnetic part 50 can be in the form of a separate component, such as a magnetic sheet, a magnet, etc., or can be in the form of one or more continuous magnetic layers formed by one or more of a magnetic adhesive, a magnetic film, a magnetic plating layer, etc., or can be in the form of one or more discontinuous magnetic layers formed by one or more of a magnetic adhesive, a magnetic film, a magnetic plating layer, etc.

[0101] Of course, in some embodiments of the present application, the magnetic part 50 can be provided on the side of the keyboard substrate 32 facing or away from the balance bar 33, for example, as shown in Figure 10 , the magnetic part 50 is provided on the bottom of the keyboard substrate 32, i.e., on the side of the keyboard substrate 32 away from the balance bar 33. Alternatively, part or all of the keyboard substrate 32 contains the magnetic part 50, which can be understood as part or all of the keyboard substrate 32 being made of a magnetic material.

[0102] It is easy to understand that the main cause of the noise is often due to the collision between the two ends of the balance bar 33 and the assembly slots 321a and 321b, so in some embodiments of the present application, the magnetic part 50 can be provided on the assembly slot 321a (and / or 321b), for example Figure 11 , the magnetic part 50 can be provided on the inner wall of the assembly slot 321a or the assembly slot 321b, so that the two ends of the balance bar 33 and the assembly slot 321a (321b) form a constraint relationship.

[0103] In some embodiments of the present application, the top end of the two opposite assembly side walls 321 can also have opposite convex edges 321d, for example, as shown in Figure 4 , the top end of one of the two assembly side walls 321 is provided with a convex edge 321d, and the top end of the opposite assembly side wall 321 is also provided with a convex edge 321d, and the two convex edges 321d are opposite. The top end of the assembly slot 321a and the assembly slot 321b extends to the bottom surface of the convex edge 321d, and the hooks 331a and 331b at the two ends of the balance bar 33 are also prone to collision with the convex edge 321d to generate noise, in this case, the magnetic part 50 can be provided on the bottom of the convex edge 321d, as shown in Figure 12 .

[0104] In some embodiments of the present application, the number of magnetic parts 50 is two, one of which can be located in the keyboard substrate 32, for example, as shown in Figure 9 , one magnetic part 50 can be located in the through slot 325, or as shown in Figure 8As shown, one magnetic part 50 is located on the side of the keyboard substrate 32 away from the balance bar 33, and another magnetic part 50 can be located on the inner wall of the assembly slot 321a (321b), so that one of the magnetic parts (for example, the magnetic part 50 located in the through slot 325) is attracted to both ends of the balance bar 33, and the other magnetic part 50 (for example, the magnetic part 50 at the top end of the inner wall of the assembly slot 321a) is repelled from both ends of the balance bar 33. This ensures that both ends of the balance bar 33 can be attracted more tightly to the keyboard substrate 32 under the action of magnetic force in the same direction of the attractive and repulsive forces, avoiding the impact between the two ends of the balance bar 33 and the interior of the assembly slot 321a (321b) during the up and down movement, thereby generating noise.

[0105] Of course, the present application is not limited to this. Instead of providing a magnetic part 50 on the assembly slot 321a (and / or 321b), a magnetic part can also be provided on both ends of the balance bar 33. For example, Figure 13 As shown, the area where the magnetic part 50 is provided is the end region of the balance bar 33, including the hooks 331a and 331b. At this time, the interior of the assembly slot 321a and the assembly slot 321b (which can be understood as the inner wall of the assembly slot 321a and the assembly slot 321b) is a magnetically conductive inner wall that is attracted or repelled by the magnetic part 50, so that a constraint relationship is formed between the two ends of the balance bar 33 and the inner wall of the assembly slot 321a (and / or 321b).

[0106] Considering the implementation process and assembly convenience of the magnetic part 50, the magnetic part 50 can also be provided on the outer surface of the hooks 331a and 331b, for example, Figure 14 As shown, the magnetic part 50 is attracted or repelled by the assembly slot 321a (321b), so that a constraint relationship is formed between the two ends of the balance bar 33 and the assembly slot 321a (321b). Of course, the hooks 331a and 331b are also magnetic parts made of magnetic material, which can also achieve the same effect.

[0107] Of course, the present application is not limited to this. In some embodiments of the present application, in order to further strengthen continuous production and rapid assembly, and to improve production and assembly efficiency, the entire surface of the balance bar 33 can be provided with a magnetic part 50, as shown. Figure 15 Alternatively, part or all of the balance bar 33 contains a magnetic part 50, which can be understood as part or all of the balance bar 33 being made of magnetic material.

[0108] It should be noted that in embodiments where the balance bar 33 has a magnetic part 50, in general, the keyboard substrate 32 itself is stainless steel with magnetic attraction, and in special cases, if the keyboard substrate 32 itself does not have magnetic attraction, a magnetic material can be added to the keyboard substrate 32, for example, an iron block is provided in the through slot 325 of the keyboard substrate 32.

[0109] In some other embodiments of the present application, the magnetic portion 50 can also be provided on the balance bar 33 and the keyboard substrate 32 simultaneously, or part or all of the balance bar 33 and part or all of the keyboard substrate 32 are made of magnetic material.

[0110] In the embodiments of the present application, the magnetic portion 50 can be two, and the two magnetic portions 50 can be a first magnetic portion and a second magnetic portion. One of the first magnetic portion and the second magnetic portion is located at the two ends of the balance bar 33, and the other of the first magnetic portion and the second magnetic portion is located on the keyboard substrate 32. The first magnetic portion and the second magnetic portion attract or repel each other, or part of one of the first magnetic portion and the second magnetic portion repels the other, and the remaining part of one of the first magnetic portion and the second magnetic portion attracts the other. For example, part or all of the balance bar 33 is the first magnetic portion, or the surface of part or all of the balance bar 33 is provided with the first magnetic portion; part or all of the keyboard substrate 32 is the second magnetic portion, or the surface of part or all of the keyboard substrate 32 is provided with the second magnetic portion. The arrangement of the first magnetic portion and the second magnetic portion on the balance bar 33 and the keyboard substrate 32 respectively can be referred to the description of the above embodiments. Figure 8 - Figure 15

[0111] By respectively providing the magnetic portion 50 on the balance bar 33 and the keyboard substrate 32, the magnetic portion 50 causes the balance bar 33 and the keyboard substrate 32 to generate attractive force, repulsive force, or attractive force and repulsive force in the same direction, so that the balance bar 33 is not easy to produce resonance and forced vibration, thereby reducing the noise of the two ends of the balance bar 33 colliding with the groove wall of the assembly groove 321a (321b).

[0112] The embodiments of the magnetic portion will be described in detail through several experimental examples.

[0113] Embodiment One

[0114] Referring to FIG. 1, Figure 15 In this embodiment, a 100 μm thick ferrite thin layer is evaporated on the entire surface of the balance bar 33 by using an atomic layer evaporation process, and other structures on the keyboard device 30 remain unchanged. The ferrite thin layer and the assembly groove 321a (321b) of the keyboard substrate 32 with magnetic attraction generate attractive force, so that the balance bar 33 is not easy to produce resonance and forced vibration, thereby reducing the noise of the two ends of the balance bar 33 colliding with the groove wall of the assembly groove 321a (321b).

[0115] The keyboard structure provided with the magnetic portion 50 in this embodiment will be compared with the keyboard structure without the magnetic portion 50. After multiple noise tests, it is found that the collision noise of the experimental example of the present application is reduced by about 3.2 dB.​

[0116] Embodiment Two

[0117] Reference Figure 9 As shown, the magnetic part 50 is arranged in the through slot 325 of the keyboard substrate 32, and the magnetic part 50 is specifically an N48 neodymium boron-iron magnetic sheet. For example, in this embodiment, an N48 neodymium boron-iron magnetic sheet with the same size as the through slot 325 is attached in the through slot 325 of the keyboard substrate 32, and other structures of the keyboard device 30 remain unchanged. The neodymium boron-iron magnetic sheet and the balance bar 33 with magnetic attraction generate an attractive force, and the balance bar 33 is not prone to resonance and forced vibration, so that the noise caused by the collision of the two ends of the balance bar 33 with the slot wall of the assembly slot 321a (321b) is reduced.

[0118] The keyboard structure provided with the magnetic part 50 in this embodiment will be compared with the keyboard structure without the magnetic part 50, and it is found through multiple noise tests that the collision noise of the experimental example of the present application is reduced by about 10 dB.

[0119] Embodiment Three

[0120] Reference Figure 10 As shown, the magnetic part 50 is arranged on the bottom of the keyboard substrate 32, and the magnetic part 50 is specifically an iron oxide magnetic film. For example, in this embodiment, a continuous layer of iron oxide magnetic film is attached to the bottom surface of the keyboard substrate 32, and other structures of the keyboard device 30 remain unchanged. The iron oxide magnetic film and the balance bar 33 with magnetic attraction generate an attractive force, and the balance bar 33 is not prone to resonance and forced vibration, so that the noise caused by the collision of the two ends of the balance bar 33 with the slot wall of the assembly slot 321a (321b) is reduced.

[0121] The keyboard structure provided with the magnetic part 50 in this embodiment will be compared with the keyboard structure without the magnetic part 50, and it is found through multiple noise tests that the collision noise of the experimental example of the present application is reduced by about 5 dB.

[0122] Embodiment Four

[0123] The magnetic part 50 is arranged on the balance bar 33 and the keyboard substrate 32, and the magnetic part 50 is specifically magnetic powder. For example, in this embodiment, magnetic powder is added to the composition of the balance bar 33 and the keyboard substrate 32, and the structure of the keyboard device 30 remains unchanged. The balance bar 33 and the keyboard substrate 32 generate an attractive force, and the balance bar 33 is not prone to resonance and forced vibration, so that the noise caused by the collision of the two ends of the balance bar 33 with the slot wall of the assembly slot 321a (321b) is reduced.

[0124] The keyboard structure provided with the magnetic part 50 in this embodiment will be compared with the keyboard structure without the magnetic part 50, and it is found through multiple noise tests that the collision noise of the experimental example of the present application is reduced by about 5 dB.

[0125] Example Five

[0126] Reference Figure 11 And Figure 12 As shown in FIG. 1, the magnetic part 50 is arranged on the inner wall of the assembly groove 321a and the assembly groove 321b and the bottom surface of the protrusion 321d. For example, the magnetic part 50 is specifically a magnetic glue. In this application, the magnetic liquid (i.e., the magnetic glue) is attached on the inner wall of the assembly groove 321a and the assembly groove 321b and the bottom surface of the protrusion 321d by the point coating method, and the structure of the keyboard device 30 is unchanged. The balance bar 33 with magnetic attraction generates an attractive force between the assembly groove 321a and the assembly groove 321b, and the balance bar 33 is not easy to produce resonance and forced vibration, so as to reduce the noise that the two ends of the balance bar 33 collide with the groove wall of the assembly groove 321a (321b).

[0127] The keyboard structure provided with the magnetic part 50 in this embodiment will be compared with the keyboard structure without the magnetic part 50. After multiple noise tests, it is found that the collision noise of the experimental example of this application is reduced by about 5dB.

[0128] In summary, several experimental examples fully illustrate that arranging the magnetic part on at least one of the balance bar and the keyboard substrate can reduce the noise generated by the collision between the balance bar and the keyboard substrate or the assembly groove, achieve the purpose of reducing vibration and noise of the keyboard, improve the keyboard noise problem, and solve the problem that the existing keyboard has relatively large noise during use due to the collision and resonance between the balance bar and the assembly groove of the keyboard substrate.
