[0001] This application relates to the field of electronic device technology, and in particular to headphones. Background Technology

[0002] With the increasing popularity of electronic devices, they have become indispensable social and entertainment tools in people's daily lives, and people's demands for electronic devices are also getting higher and higher. Electronic devices such as headphones and smart glasses are also widely used in people's daily lives. They can be used in conjunction with terminal devices such as mobile phones and computers to provide users with an auditory feast.

[0003] Ear-hook or clip-on headphones typically have metal parts to connect two different shells. How to achieve a reliable connection between the metal parts and the shells has become a widely concerned technical problem. Utility Model Content

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide an earphone, which includes a first shell assembly, a second shell assembly, and a metal part. The two ends of the metal part are respectively connected to the first shell assembly and the second shell assembly. At least one of the first shell assembly and the second shell assembly includes a first rigid shell and a first soft covering. The first rigid shell is molded to wrap around the end of the metal part and form a first sub-accommodating space. A portion of the metal part is provided to be exposed from the interior of the first sub-accommodating space to form a first exposed portion. The first rigid shell is further provided with a window, and another portion of the metal part is provided to be exposed from the window to form a second exposed portion. The first exposed portion and the second exposed portion are arranged opposite to each other along a predetermined direction, which intersects with the length direction of the metal part. The first soft covering covers the periphery of the first rigid shell and covers the window.

[0005] In some embodiments, the area of ​​the first exposed portion is between 0.2 and 15 mm. 2 between.

[0006] In some embodiments, the first exposed portion has a plurality of first sub-exposed portions, and the first rigid housing has a plurality of exposed windows. The plurality of exposed windows are in communication with the first sub-accommodating space, and the plurality of first sub-exposed portions are exposed to the interior of the first sub-accommodating space through the plurality of exposed windows.

[0007] In some embodiments, the earphone further includes an insert embedded in the window and covering the second exposed portion, the insert being covered by a first soft coating.

[0008] In some embodiments, the area of ​​the second exposed portion is greater than 0.5 to 17 mm. 2 .

[0009] In some embodiments, the metal part is provided in a sheet shape and includes a first main surface and a second main surface disposed opposite to each other in the thickness direction. The first main surface is configured to be exposed from the interior of the first sub-accommodating space to form a first exposed portion, and the second main surface is configured to be exposed from a window to form a second exposed portion.

[0010] In some embodiments, when worn, the second housing assembly is disposed within the concha cavity, the first housing assembly abuts against the back of the auricle, the metal part is wrapped around the periphery of the helix, and the first main surface is disposed facing the auricle.

[0011] In some embodiments, the ratio of the dimension of the second exposed portion along the width direction of the metal part to the width of the metal part is between 0.5 and 1.

[0012] In some embodiments, the earphone further includes an insert embedded in the window and covering the second exposed portion, the insert being covered by a first soft coating, and the metal component further including two side surfaces disposed along the length direction and connecting the first main surface and the second main surface, the window being further configured such that one of the two side surfaces is exposed.

[0013] In some embodiments, at least one of the first housing assembly and the second housing assembly further includes a second rigid housing, a third rigid housing, and a second soft covering. One end of the second rigid housing is detachably connected to the first rigid housing, and the other end of the second rigid housing is connected to the third rigid housing. The second rigid housing forms a second sub-accommodating space communicating with the first sub-accommodating space, and the third rigid housing forms a third sub-accommodating space communicating with the second sub-accommodating space. The second soft covering covers the third rigid housing, wherein the outer surfaces of the first soft covering, the second rigid housing, and the second soft covering are smoothly transitioned.

[0014] The beneficial effects of this application are as follows: In the solution of this application, the metal part connects the first rigid shell in the first shell assembly and the second shell assembly. By setting the first rigid shell to be molded and wrapped around the end of the metal part, the first rigid shell can be more firmly fixed to the end of the metal part. Furthermore, during the molding process of the first rigid shell, in order to reduce the shaking of the metal part during the molding process, two support members can be used to support and fix the metal part from both sides in a predetermined direction intersecting the length direction of the metal part, so that the relative position of the first rigid shell and the metal part is more accurate, which is conducive to further ensuring the reliable connection between the first rigid shell and the metal part. After the first rigid shell is molded, one of the support members supports one side of the metal part through the first sub-accommodating space, and the other support member supports the other side of the metal part through the opening. After the support members are removed, a part of the metal part is exposed from the inside of the first sub-accommodating space to form the first exposed part, and the other part of the metal part is exposed from the opening to form the second exposed part.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0024] The following is an exemplary description of the headphones in the example embodiment.

[0025] Combination Figure 1 The headphones 1 are audio converters capable of receiving electrical signals from a media player or receiver and converting them into sound waves that can be heard by the user. In some embodiments, the headphones 1 can be open-back headphones, such as ear-hook headphones, behind-the-ear headphones, or clip-on headphones.

[0026] In some embodiments, as Figure 1 as well as Figure 2 As shown, the earphone 1 may include a first housing assembly 10, a second housing assembly 20, and a metal member 30. The two ends of the metal member 30 can be connected to the first housing assembly 10 and the second housing assembly 20, respectively. As an example, the speaker of the earphone 1 can be placed in the second housing assembly 20, and the battery can be placed in the first housing assembly 10. In some embodiments, the speaker and battery of the earphone 1 may also be placed together in either the first housing assembly 10 or the second housing assembly 20. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0027] In some embodiments, the metal part 30 can be a metal part with high elasticity that is easily bent and deformed, such as a titanium sheet or titanium wire. By connecting the first housing assembly 10 and the second housing assembly 20 at both ends of the metal part 30, the position of the metal part 30 in the earphone 1 can be deformed under the action of external force, thereby allowing the earphone 1 to be hooked or clipped onto the ear. In other embodiments, the metal part 30 can also be a metal part with low elasticity that is not easily deformed, such as a copper strip or iron rod.

[0028] Furthermore, such as Figure 2 as well as Figure 3 As shown, at least one of the first housing assembly 10 and the second housing assembly 20 may include a first rigid housing 110 and a first soft covering 120. The first rigid housing 110 may be molded to wrap around the end of the metal part 30 and form a first sub-accommodating space 111.

[0029] The first rigid shell 110 can be made of a metal, hard plastic, or hard rubber with high hardness. Using a material with high hardness to make the first rigid shell 110 and connect it with the metal part 30 can achieve a more secure connection between the metal part 30 and the first rigid shell 110, making the structure of the earphone 1 more compact and stable.

[0030] The molding method refers to the method of using a mold to shape solid or liquid raw materials into the required shape of the shell. For example, the molding method can include injection molding or thermoforming. By using molding methods such as injection molding or thermoforming to form the first rigid shell 110 at the end of the metal part 30, the formation of the first rigid shell 110 can be simplified, and the connection between the first rigid shell 110 and the metal part 30 can be made more secure.

[0031] However, when the raw materials for the solid or liquid metal part 30 are wrapped around the metal part 30, the metal part 30 is prone to shaking or wobbling, which changes the relative position between the metal part 30 and the first rigid shell 110, thus affecting the subsequent structural assembly and structural stability of the earphone 1. Therefore, during the molding process of the first rigid shell 110, in order to reduce the shaking of the metal part 30 during molding, two support members can be used to support and fix the metal part 30 from both sides, making the relative position between the first rigid shell 110 and the metal part 30 more accurate, which is conducive to further ensuring a reliable connection between the first rigid shell 110 and the metal part 30.

[0032] like Figure 4 As shown, a portion of the metal member 30 may be exposed from the interior of the first sub-accommodating space 111 to form a first exposed portion 310. A window 112 may be further provided on the first rigid housing 110, and another portion of the metal member 30 may be exposed from the window 112 to form a second exposed portion 320. The first exposed portion 310 and the second exposed portion 320 are arranged opposite to each other along a predetermined direction, which intersects the length direction of the metal member 30. In other words, the first exposed portion 310 and the second exposed portion 320 are located on opposite sides of the length direction of the metal member 30.

[0033] As an example, the predetermined direction can be as follows: Figure 4 The direction indicated by the middle arrow D. Corresponding to the locations of the first exposed portion 310 and the second exposed portion 320, the length direction of the metal part 30 can be as follows: Figure 4 The direction indicated by the middle arrow E.

[0034] Therefore, during the molding process of the first rigid shell 110, in order to reduce the shaking of the metal part 30 during molding, two support members can be used to support and fix the metal part 30 from both sides in a predetermined direction, so that the relative position of the first rigid shell 110 and the metal part 30 is more accurate, which is conducive to further ensuring the reliable connection between the first rigid shell 110 and the metal part 30. After the first rigid shell 110 is molded, one of the support members supports one side of the metal part 30 through the first sub-accommodating space 111, and the other support member supports the other side of the metal part 30 through the opening 112. After the support members are removed, a part of the metal part 30 is exposed from the inside of the first sub-accommodating space 111 to form the first exposed part 310, and another part of the metal part 30 is exposed from the opening 112 to form the second exposed part 320.

[0035] like Figure 4As shown, the first soft coating 120 can cover the periphery of the first rigid shell 110 and cover the window 112. The first soft coating 120 can be made of flexible materials such as silicone or TPE (thermoplastic elastomer).

[0036] By setting a first soft coating 120 to cover the periphery of the window 112 and the first hard shell 110, the surface of the earphone 1 can be made smoother, improving the aesthetics of the earphone 1.

[0037] In some embodiments, when the earphone 1 is worn, the second shell assembly 20 can abut against the user's concha cavity, the first shell assembly 10 can abut against the back of the auricle, and the metal part 30 is wrapped around the periphery of the helix. The metal part 30 can rest on the auricle to connect the first shell assembly 10 and the second shell assembly 20. Furthermore, the first soft covering 120 wraps around the metal part 30 and has a certain degree of softness, so when the user wears the earphone 1, the body can contact the first soft covering 120 to contact the soft part of the earphone 11, thereby improving the user experience.

[0038] In some embodiments, one of the first housing assembly 10 and the second housing assembly 20 may be provided with a first rigid housing 110 and a first soft coating 120. In other words, the metal member 30 is connected to the first rigid housing 110 in the first housing assembly 10 or the second housing assembly 20 at only one end, and the end of the metal member 30 connected to the first rigid housing 110 forms a first exposed portion 310 exposed in the first sub-accommodating space 111 and a second exposed portion 320 exposed in the window 112.

[0039] In other embodiments, both the first housing assembly 10 and the second housing assembly 20 may have a first rigid housing 110 and a first soft coating 120. The two first rigid housings 110 are respectively formed on the two ends of the metal member 30 and connected to the metal member 30. The two first rigid housings 110 also respectively form a first sub-accommodating space 111 and a window 112. The two ends of the metal member 30 respectively form a first exposed portion 310 exposed to the corresponding first sub-accommodating space 111 and a second exposed portion 320 exposed to the corresponding window 112.

[0040] In some embodiments, the area of ​​the first exposed portion 310 is between 0.2 and 15 mm. 2 between.

[0041] For example, the area of ​​the first exposed portion 310 can be 0.2 mm. 2 0.8mm 2 3mm 2 7mm 2 12mm 2 Or 15mm2 Equal values.

[0042] If the area of ​​the first exposed portion 310 is less than 0.2 mm 2 This would cause the support point of the metal part 30 in the first sub-accommodating space 111 to be too small, thus affecting the fixing effect of the metal part 30. If the area of ​​the first exposed part 310 is greater than 15mm², it will affect the fixing effect of the metal part 30. 2 This will increase the material cost of the metal parts 30, or occupy the volume of the first sub-accommodation space 111, thereby affecting the molding effect of the first rigid shell 110 or the subsequent assembly and use effect.

[0043] Therefore, the area of ​​the first exposed portion 310 is set between 0.2 and 15 mm. 2 This arrangement not only allows the metal part 30 to have a sufficiently large support point, enabling the support member to more stably support the metal part 30, but also reduces the material cost of the metal part 30 and the size of the corresponding first exposed part 310 in the first sub-accommodation space 111, thereby reducing the impact of the metal part 30 on the forming or subsequent assembly of the first rigid shell 110.

[0044] In some embodiments, other components may be added to the first sub-accommodating space 111, or the position corresponding to the first exposed portion 310 may be used to make the first rigid housing 110 and other components snap-fit ​​together to improve the space utilization of the earphone 1.

[0045] In some embodiments, as Figure 5 As shown, the first exposed portion 310 may include a plurality of first sub-exposed portions 311, and the first rigid housing 110 may have a plurality of exposed windows 113. The plurality of exposed windows 113 may communicate with the first sub-accommodating space 111, and the plurality of first sub-exposed portions 311 are exposed to the interior of the first sub-accommodating space 111 through the plurality of exposed windows 113.

[0046] The plurality of exposed windows 113 can correspond one-to-one with a plurality of first sub-exposed portions 311. The first rigid housing 110 can be interlocked with other components through at least one exposed window 113, and the shape of the exposed window 113 used for interlocking can be set to the shape required by the interlocking structure. The sum of the areas of the plurality of first sub-exposed portions 311 is set between 0.2 and 15 mm. 2 between.

[0047] The arrangement of multiple exposed windows 113 not only allows the first rigid housing 110 to connect with other structural components via the exposed windows 113, but also allows for greater freedom in the shape design of the exposed windows 113, reducing the likelihood that the exposed windows 113 will be too large to be easily snapped and fixed with other structural components. If some of the exposed windows 113 are designed with a smaller area to accommodate the snap-fit ​​structure, the other exposed windows 113 can further supplement the area that can expose the first exposed portion 310, so that multiple exposed windows 113 can correspondingly expose a sufficient area of ​​the first sub-exposed portion 311.

[0048] Therefore, the arrangement of multiple exposed windows 113 allows the first exposed portion 310 to have a sufficient exposed area to be supported by the support member, so that the metal part 30 has a sufficiently large support point position. Thus, during the molding process of the first rigid structure, the support member can more stably support the metal part 30 through the corresponding positions of the multiple exposed windows 113.

[0049] For example, such as Figure 5 As shown, the number of exposed windows 113 and the number of first sub-exposed portions 311 can both be two. The two first sub-exposed portions 311 are exposed inside the first sub-accommodating space 111 through the two exposed windows 113 respectively. The first rigid housing 110 can be snapped into other housing components through one exposed window 113, and the other exposed window 113 is used to supplement the exposed area of ​​the first exposed portion 310, so that the sum of the areas exposed in the two exposed windows 113 is between 0.2 and 15 mm. 2 between.

[0050] Of course, in other embodiments, the number of exposed windows 113 may also be one, with the first exposed portion 310 exposed to the interior of the first sub-accommodating space 111 through the exposed window 113, and the area of ​​the exposed window 113 being between 0.2 and 15 mm. 2 between.

[0051] In some embodiments, as Figure 4 As shown, the earphone 1 may further include an insert 40, which can be embedded in the opening 112 and cover the second exposed portion 320. The first soft coating 120 can cover the insert 40. The insert 40 can be made of flexible materials such as silicone or TPE (thermoplastic elastomer), or it can be made of rigid materials such as plastic or metal. The insert 40 can fill the opening 112.

[0052] Specifically, during the assembly of the earphone 1, after the first hard shell 110 is formed at the end of the metal part 30, an insert 40 can be added to the window 112, and then a first soft coating 120 is added to the periphery of the first hard shell 110. The first soft coating 120 wraps the insert 40 and the periphery of the first hard shell 110.

[0053] This design facilitates the first soft coating 120 to wrap around the insert 40 and the outer periphery of the first hard shell 110, and makes the surface of the first soft coating 120 smoother after wrapping around the insert 40 and the outer periphery of the first hard shell 110. The first soft coating 120 is less likely to be dented at the position corresponding to the window 112, thereby making the surface of the earphone 1 flatter.

[0054] In some embodiments, the area of ​​the second exposed portion 320 may be between 0.5 and 17 mm. 2 Between. For example, the area of ​​the second exposed portion 320 can be 0.5 mm. 2 1.32mm 2 4.5mm 2 6mm 2 13mm 2 Or 17mm 2 Equal values.

[0055] If the area of ​​the second exposed portion 320 is less than 0.5mm 2 If the area of ​​the window 112 corresponding to the second exposed portion 320 is too small, it will increase the difficulty of forming the window 112, the difficulty of preparing the insert 40 embedded in the window 112, and the difficulty of assembling the insert 40 into the window 112. If the area of ​​the second exposed portion 320 is greater than 17 mm, it will be difficult to form the window 112. 2 If the area of ​​the window 112 corresponding to the second exposed part 320 is too large, the window 112 will occupy a large space volume in the first rigid shell 110, thereby affecting the molding effect of the first rigid shell 110 or the subsequent assembly and use effect.

[0056] Therefore, the area of ​​the second exposed portion 320 is set between 0.5 and 17 mm. 2 This not only allows one side of the metal part 30 to have a sufficiently large support point, so that the support can more stably support the metal part 30, but also reduces the size of the window 112, thereby reducing the size of the first rigid shell 110, and thus reducing the impact of the metal part 30 on the forming or subsequent assembly of the first rigid shell 110.

[0057] In some embodiments, as Figures 2 to 7As shown, the metal part 30 can be arranged in a sheet shape and includes a first main surface 330 and a second main surface 340 arranged opposite to each other in the thickness direction. The first main surface 330 can be configured to be exposed from the interior of the first sub-accommodating space 111 to form a first exposed portion 310, and the second main surface 340 can be configured to be exposed from the opening 112 to form a second exposed portion 320. As an example, the thickness direction of the metal part 30 can be as follows: Figure 4 The direction indicated by the middle arrow F.

[0058] The metal part 30 is sheet-shaped, which allows it to occupy less space. When the first rigid shell 110 is formed at the end of the metal part 30, the space occupied by the metal part 30 in the first rigid shell 110 can also be reduced, thereby reducing the size of the first rigid shell 110. For example, the metal part 30 can be a titanium sheet.

[0059] Of course, in other embodiments, the metal part 30 may also take the form of other shapes such as a bar, an S-shaped spring, or a sheet-like hollow shape.

[0060] Furthermore, the thickness direction F of the metal part 30 is perpendicular to the length direction E. By setting the first exposed portion 310 and the second exposed portion 320 on two opposing main surfaces in the thickness direction F of the metal part 30, the support assembly can more stably fix the metal part 30 through the first main surface 330 and the second main surface 340 during the molding of the first rigid shell 110, so that the end of the metal part 30 is less likely to shake or swing and shift.

[0061] In some embodiments, when worn, the second housing assembly 20 may be disposed within the concha cavity, the first housing assembly 10 may abut against the back of the auricle, the metal part 30 may be disposed around the periphery of the helix, and the first main surface 330 may be disposed facing the auricle.

[0062] The metal part 30 can be attached to the ear to connect the first housing assembly 10 and the second housing assembly 20. The metal part 30 is sheet-shaped and the first main surface 330 faces the ear, which allows the non-end portion of the metal part 30 to easily undergo elastic deformation and bend, so that the user can put on or take off the earphone 1 by bending the metal part 30.

[0063] In some embodiments, the ratio of the dimension of the second exposed portion 320 along the width direction of the metal member 30 to the width of the metal member 30 is between 0.5 and 1. The width direction, length direction E, and thickness direction F of the metal member 30 are all perpendicular to each other.

[0064] As an example, the width direction of the metal part 30 can be as follows: Figure 7As indicated by the middle arrow H, the dimension of the second exposed portion 320 along the width direction H of the metal part 30 can be as follows: Figure 7 As shown in the mid-width L1, the width of the metal part 30 along the width direction H can be as follows: Figure 7 The width L2 is shown.

[0065] For example, the dimension of the second exposed portion 320 along the width direction H of the metal part 30 can be 1.4mm, 1.56mm or 3mm, etc., and the width of the metal part 30 along the width direction H can be 2.24mm, 2.8mm, 2.24mm or 3mm, etc., and the ratio of the two can be 0.5, 0.696 or 1, etc.

[0066] If the ratio of the dimension of the second exposed portion 320 along the width direction H of the metal part 30 to the width of the metal part 30 is less than 0.5, it means that the dimension of the second exposed portion 320 along the width direction H of the metal part 30 is small, which will make the position of the support point of the metal part 30 in the window 112 too small, thus affecting the fixing effect of the metal part 30.

[0067] Therefore, by setting the ratio of the dimension of the second exposed portion 320 along the width direction H of the metal part 30 to the width of the metal part 30 to be between 0.5 and 1, the second exposed portion 320 can have sufficient support points in the width direction H, so that the support assembly can more stably support the metal part 30, thereby reducing the displacement phenomenon such as shaking or swaying of the metal part 30.

[0068] In some embodiments, as Figures 5 to 7 As shown, the metal part 30 further includes two side surfaces 350 disposed along the length direction E and connecting the first main surface 330 and the second main surface 340, and the window 112 is further configured such that one of the two side surfaces 350 is exposed.

[0069] Specifically, if one of the two side surfaces 350 is exposed in the window 112, it means that both the second main surface 340 and one of the two side surfaces 350 are exposed in the window 112. Therefore, during the process of forming the first rigid shell 110 at the end of the metal part 30, the second main surface 340 and one of the two side surfaces 350 of the metal part 30 can be fixed or clamped by the support.

[0070] This configuration allows the support member to fix and limit the two surfaces of the metal part 30 at the position corresponding to the window 112, thereby strengthening the fixing effect of the metal part 30 and making it less likely for the metal part 30 to shift.

[0071] In some embodiments, as Figure 2As shown, at least one of the first housing assembly 10 and the second housing assembly 20 may further include a second rigid housing 130, a third rigid housing 140, and a second soft covering 150. One end of the second rigid housing 130 is detachably connected to the first rigid housing 110, and the other end of the second rigid housing 130 is connected to the third rigid housing 140. The second rigid housing 130 forms a second sub-accommodating space 131 communicating with the first sub-accommodating space 111, and the third rigid housing 140 forms a third sub-accommodating space 141 communicating with the second sub-accommodating space 131. The second soft covering 150 covers the third rigid housing 140.

[0072] Specifically, by configuring at least one of the first housing assembly 10 and the second housing assembly 20 as a plurality of rigid housings connected together, it is convenient to assemble at least one of the first housing assembly 10 and the second housing assembly 20, and it is also convenient to assemble other components in the first sub-accommodating space 111, the second sub-accommodating space 131 and the third sub-accommodating space 141, and it can also make the structure of the headphones more robust.

[0073] The outer surfaces of the first soft coating 120, the second hard shell 130, and the second soft coating 150 transition smoothly. Specifically, a smooth transition means that the height difference at the seam is less than or equal to 0.5 mm. This design makes the surface of the earphone 1 smoother, thereby improving the aesthetics of the earphone 1.

[0074] The second soft covering 150 can also be made of flexible materials such as silicone or TPE (thermoplastic elastomer). During the use of the earphone 1, the corresponding position of the third rigid shell 140 abuts against the auricle. Therefore, by providing the second soft covering 150 to cover the third rigid shell 140, the user's body can come into contact with the soft part of the earphone 1 when wearing it, thereby improving the user experience.

[0075] In some embodiments, one of the first housing assembly 10 and the second housing assembly 20 may be provided with a first rigid housing 110 and a first soft coating 120, which are disposed at one end of the metal member 30. Corresponding to the first rigid housing 110 and the first soft coating 120, one of the first housing assembly 10 and the second housing assembly 20 is provided with a second rigid housing 130, a third rigid housing 140, and a second soft coating 150, with the second rigid housing 130 correspondingly connected to the first rigid housing 110 and the first soft coating 120.

[0076] In some embodiments, both the first housing assembly 10 and the second housing assembly 20 may have a first rigid housing 110 and a first soft coating 120, with the two first rigid housings 110 and the two first soft coatings 120 respectively disposed at the two ends of the metal part 30. Corresponding to the two first rigid housings 110 and the two first soft coatings 120, both the first housing assembly 10 and the second housing assembly 20 may be provided with a second rigid housing 130, a third rigid housing 140, and a second soft coating 150, with the two second rigid housings 130 respectively connected to the corresponding first rigid housing 110 and the corresponding first soft coating 120.

[0077] In summary, in the solution of this application, the metal part 30 connects to the first rigid shell 110 in the first shell assembly 10 and the second shell assembly 20. By forming the first rigid shell 110 around the end of the metal part 30, the first rigid shell 110 can be more firmly fixed to the end of the metal part 30. Furthermore, during the forming process of the first rigid shell 110, in order to reduce the shaking of the metal part 30 during the forming process, two support members can be used to support and fix the metal part 30 from both sides in a predetermined direction, so that the relative position of the first rigid shell 110 and the metal part 30 is more accurate, which is conducive to further ensuring the reliable connection between the first rigid shell 110 and the metal part 30. After the first rigid shell 110 is formed, one of the supports supports one side of the metal part 30 via the first sub-accommodating space 111, and the other support supports the other side of the metal part 30 via the opening 112. After the support is removed, a part of the metal part 30 is exposed from the inside of the first sub-accommodating space 111 to form a first exposed portion 310, and another part of the metal part 30 is exposed from the opening 112 to form a second exposed portion 320.
