[0026] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0027] Open-back headphones are generally equipped with an ear hook structure, which will generally produce unpredictable deformation after being demolded, which can easily lead to an increase in the product defect rate.
[0028] For the above situation, please see Figure 1-Figure 2 The present application proposes an ear hook shaping jig 1 for placing the ear hook 2 in an open-type earphone, and can shape and correct the ear hook 2 that has just been produced and demolded.
[0029] The ear hook shaping jig 1 includes a base 10, which has a first side surface 11. A placement groove 12 is provided on the first side surface 11. The placement groove 12 is used to place the ear hook 2. A clamping portion 13 is provided on the inner side wall of the placement groove 12. The clamping portion 13 is used to contact the ear hook 2.
[0030] Specifically, the inner side wall of the placement slot 12 and the clamping portion 13 are jointly arranged to form a receiving space 14 for accommodating the ear hook 2. When the ear hook 2 is placed in the receiving space 14, the inner side wall of the placement slot 12 can provide support for the ear hook 2, and the clamping portion 13 can provide a limit for the ear hook 2, thereby making the placement of the ear hook 2 in the receiving space 14 more stable.
[0031] It should be noted that, in the embodiment of the present application, a placement groove 12 having a clamping portion 13 is provided on the base 10, so that the ear hook shaping jig 1 can reduce the deformation of the ear hook 2 after demolding, and play a corrective role for the ear hook 2 after demolding, thereby improving the product yield. In addition, in the embodiment of the present application, only a single ear hook shaping jig 1 is needed to place the ear hook 2 and shape and correct it. The ear hook shaping jig 1 has a simple structure and a low production cost. It is understandable that the ear hook shaping jig 1 in this embodiment can act as a blister tray to store and transport the ear hook 2 while reducing the deformation of the ear hook 2.
[0032] It should also be noted that the base 10 can be a plastic base 10, that is, the ear hook shaping jig 1 can be produced by a vacuum forming process, which not only has a low cost but also a simple production process and can be produced in large quantities.
[0033] In some embodiments, as Figure 1As shown, the base 10 has a top plate 16 and a peripheral side plate 17 connected to the peripheral side of the top plate 16, the top plate 16 and the peripheral side plate 17 are connected by an arc surface or an inclined surface, and the first side surface 11 is located on the upper surface of the top plate 16, that is, the placement groove 12 is located on the upper surface of the top plate 16; wherein, the top plate 16 and the peripheral side plate 17 are jointly arranged to form a stacking cavity, taking two ear hook shaping jigs 1 as an example, the two ear hook shaping jigs 1 can be stacked in sequence along a first direction, and the first direction is a direction perpendicular to the first side surface 11, for example, the first ear hook shaping jig The earhook shaping jig is placed above the second earhook shaping jig, and the top plate 16 and part of the peripheral side plates 17 of the second earhook shaping jig are accommodated in the overlapping cavity of the first earhook shaping jig. Similarly, the placement of multiple earhook shaping jigs 1 is similar. As a result, the earhook shaping jig 1 in this embodiment can not only serve as a transport tray to store and transport the earhook 2 while reducing the deformation of the earhook 2, but also reduce the space required to be occupied by a large number of earhook shaping jigs 1 when multiple earhook 2 are transported (one earhook 2 is placed in each earhook shaping jig 1).
[0034] Please continue to see Figure 1-Figure 2 In some embodiments of the present application, multiple clamping portions 13 are provided, and the multiple clamping portions 13 are spaced apart on the inner sidewall of the placement groove 12. It is easy to understand that the provision of multiple clamping portions 13 can secure the ear hook 2, further ensuring a more stable placement of the ear hook 2 within the accommodation space 14, thereby reducing deformation of the ear hook 2 after removal from the mold and improving the yield rate of the ear hook 2.
[0035] See Figure 2 In some embodiments of the present application, an arc-shaped transition portion 15 is provided between the inner wall of the placement groove body 12 and the first side surface 11, and the inner wall of the placement groove body 12 and the first side surface 11 are connected through the arc-shaped transition portion 15. There are no sharp edges on the arc-shaped transition portion 15, which can reduce the impact and deformation of the ear hook 2 during the process of being placed in the accommodating space 14, thereby providing better protection for the ear hook 2.
[0036] For further information, please see Figure 2 In some embodiments of the present application, the clamping portion 13 is located on the inner sidewall of the placement slot 12 and is disposed near the arc-shaped transition portion 15. It is easy to understand that the opening of the placement slot 12 faces the arc-shaped transition portion 15, that is, the clamping portion 13 is closer to the opening of the placement slot 12. As a result, after the ear hook 2 is placed in the accommodating space 14, the clamping portion 13 can contact the side of the ear hook 2 facing the outside of the accommodating space 14, thereby achieving a clamped and fixed connection with the ear hook 2 and preventing the ear hook 2 from falling out of the accommodating space 14.
[0037] See Figure 3-Figure 4In some embodiments of the present application, the open-type earphone includes an ear hook 2 and an earphone body. The ear hook 2 includes an ear hook body 20 and a connecting portion 30 that are connected to each other. The ear hook body 20 is arc-shaped to adapt to the user's auricle. The connecting portion 30 is used to be fixedly connected to the earphone body. At this time, the ear hook body 20 surrounds and is worn on the user's auricle, thereby fixing the open-type earphone on the user's ear.
[0038] The placement groove 12 has a first groove 121 and a second groove 122. The projection shape of the first groove 121 on the first side surface 11 is an arc. The first groove 121 is used to place the ear hook body 20. That is, the shape of the first groove 121 is adapted to the shape of the ear hook body 20 to provide a more stable placement base for the ear hook body 20. The second groove 122 is connected to the first groove 121 and is used to place the connecting portion 30. The specific shape of the connecting portion 30 is related to the connection structure between the connecting portion 30 and the earphone body. Therefore, the shape of the connecting portion 30 can be different from that of the ear hook body 20. In order to ensure the integrity of the shape of the ear hook 2 after demolding, the present embodiment provides a corresponding second groove 122 for the connecting portion 30, so that the connecting portion 30 has a placement space different from the ear hook body 20. Even if the shape of the connecting portion 30 is different on different models of open-earphones, the ear hook shaping jig 1 can adapt to various shapes of connecting portions 30 on the ear hook 2, thereby improving the universality of the ear hook shaping jig 1.
[0039] Alternatively, as Figure 3 As shown, the projection shape of the second groove 122 on the first side surface 11 is square; optionally, the projection shape of the second groove 122 on the first side surface 11 can also be circular or elliptical. As long as the space of the second groove 122 is large, the second groove 122 can provide a larger placement space for the connecting part 30, reducing the restrictions of the space size and shape of the second groove 122 on the connecting part 30.
[0040] Furthermore, since the outer peripheral surface of the ear hook body 20 of the open earphone is generally a curved surface, Figure 4 As shown, the inner side wall of the first groove 121 is an arc-shaped surface, so that the shape of the first groove 121 is more adapted to the outer shape of the ear hook body 20. When the ear hook body 20 is placed in the first groove 121, the compression deformation of the shape of the ear hook body 20 caused by the inner side wall of the first groove 121 can be improved.
[0041] See Figure 3 In some embodiments of the present application, three clamping parts 13 are provided, and the three clamping parts 13 are arranged at intervals in the first groove 121 to constrain the position of the ear hook body 20. After the position of the ear hook body 20 is fixed, the ear hook 2 as a whole can present a more standard ear hook 2 shape under the correction effect of the placement groove body 12.
[0042] Among them, one end of the ear hook body 20 is connected to the connecting part 30, and the intervals between the three clamping parts 13 are evenly arranged. The first clamping part 13 is used to contact the part of the ear hook body 20 close to the connecting part 30, the second clamping part 13 is used to contact the middle part of the ear hook body 20, and the third clamping part 13 is used to contact the part of the ear hook body 20 away from the connecting part 30, thereby making the placement of the ear hook body 20 more stable under the action of the clamping part 13.
[0043] Furthermore, if Figure 4 As shown, the first groove 121 has a first inner wall 1211 and a second inner wall 1212 arranged opposite to each other, the first inner wall 1211 is used to contact the outer side of the ear hook 2, and the second inner wall 1212 is used to contact the inner side of the ear hook 2, wherein, when the open earphones are worn, the inner side of the ear hook 2 refers to the side surface of the ear hook 2 that contacts the user's auricle, and the outer side of the ear hook 2 refers to the side surface of the ear hook 2 that faces away from the user's auricle.
[0044] Specifically, the clipping parts 13 are all located on the first inner side wall 1211, or the clipping parts 13 are all located on the second inner side wall 1212, that is, the clipping parts 13 are all arranged on the same side of the ear hook 2. In this embodiment, the installation position of the clipping parts 13 in the placement groove body 12 is uniformly set to reduce the difficulty of placing the ear hook 2 and prevent the ear hook 2 from being significantly deformed due to the obstruction of the clipping part 13 when placed in the accommodating space 14.
