[0025] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.

[0026] The same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary illustration, and cannot be understood as a limitation on the present patent, for those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] In the related art, the rotating shaft structure mainly includes: a plug-in part and a plug-in sleeve, the plug-in sleeve has a positioning cavity and an opening communicating with the positioning cavity, and the plug-in part is clamped with the limiting boss inside the plug-in sleeve through the opening. At the same time, the rotating shaft is axially positioned by the spring structure inside the rotating shaft. However, the plug-in sleeve adopts a semi-closed structure, and the plug-in sleeve is provided with only one opening, which causes inconvenience in inserting or removing the plug-in part through the opening, thereby increasing the complexity of disassembling and assembling the earphone as a whole.

[0028] Figure 1 is a schematic diagram of an earphone structure provided by an embodiment of the present disclosure, Figure 2 is Figure 1 The partial exploded view of the earphone is shown. Referring to Figure 1 and Figure 2 , the earphone 000 can include a housing 100, a rotating shaft part 200, and an ear hanging part 300. The housing 100 in the earphone 000 can include a main body part 101 and a positioning shell 102. Among them, the main body part 101 can be used to accommodate a sound generating unit.

[0029] Referring to Figure 3 and Figure 4 , Figure 3 is a schematic diagram of a positioning shell structure provided by an embodiment of the present disclosure, Figure 4 is a cross-sectional view of an earphone provided by an embodiment of the present disclosure Figure 1 . The positioning shell 102 in the housing 100 can have a positioning cavity C and a first opening K1 and a second opening K2 communicating with the positioning cavity C. The main body part 101 in the housing 100 can be detachably connected with the positioning shell 102 through the first opening K1, and the side of the main body part 101 facing the first opening K1 is provided with a first limiting part 1011.

[0030] The first end of the rotating shaft part 200 in the earphone 000 is connected with the ear hanging part 300, and the second end of the rotating shaft part 200 is rotationally connected with the positioning shell 102.

[0031] The second end of the rotating shaft 200 has a first annular protrusion 201. In the state where the first limiting piece 1011 abuts against the first annular protrusion 201, the first limiting piece 1011 limits the rotating shaft 200 from being pulled out of the positioning cavity C.

[0032] In the embodiment, the main body 101 in the shell 100 can be detachably connected with the positioning shell 102 through the first opening K1, and the first annular protrusion 201 in the rotating shaft 200 is located on the side of the first limiting piece 1011 away from the second opening K2. Therefore, when the rotating shaft 200 is removed, the main body 101 only needs to be separated from the positioning shell 102. The first limiting piece 1011 in the main body 101 will no longer limit the first annular protrusion 201, so that the rotating shaft 200 can be smoothly pulled out of the positioning cavity C.

[0033] When the rotating shaft 200 is installed, the rotating shaft 200 can be first inserted into the positioning cavity C through the second opening K2, and then the main body 101 is connected with the positioning shell 102 through the first opening K1. In this way, the first limiting piece 1011 in the main body 101 extends into the positioning cavity C and is located between the first annular protrusion 201 and the second opening K2. In this way, when the rotating shaft 200 tries to be pulled out of the positioning cavity C through the second opening K2, the first limiting piece 1011 can block the first annular protrusion 201, thereby ensuring that the rotating shaft 200 is stably installed in the positioning cavity C.

[0034] Therefore, whether the rotating shaft 200 is installed or removed, the main body 101 only needs to be connected with the positioning shell 102 to achieve convenient installation and removal of the rotating shaft 200, and thus the earphone as a whole is more convenient to disassemble and assemble.

[0035] The earphone provided in the application comprises a shell, a rotating shaft and an ear hook. A main body in the shell can be detachably connected with a positioning shell through a first opening, and a first annular protrusion in the rotating shaft is located on the side of a first limiting piece away from a second opening. Therefore, when the rotating shaft is removed, the main body only needs to be separated from the positioning shell. The first limiting piece in the main body will no longer limit the first annular protrusion, so that the rotating shaft can be smoothly pulled out of the positioning cavity. When the rotating shaft is installed, the rotating shaft can be first inserted into the positioning cavity through the second opening, and then the main body is connected with the positioning shell through the first opening.

[0036] In this way, the first limiting piece in the main body part extends into the positioning cavity and is located between the first annular protrusion and the second opening. In this way, during the process that the rotating shaft tries to pull out of the positioning cavity through the second opening, the first limiting piece can block the first annular protrusion, thereby ensuring that the rotating shaft is stably installed in the positioning cavity. Therefore, whether it is to install the rotating shaft or to disassemble the rotating shaft, only by controlling the connection of the main body part and the positioning shell, the convenient installation and disassembly of the rotating shaft can be realized, and then the disassembly and assembly of the whole earphone become more convenient.

[0037] In the present application, since the second end of the rotating shaft 200 is designed with the first annular protrusion 201, and forms effective axial positioning with the first limiting piece 1011 on the main body part 101, the stability and reliability of the rotating shaft 200 during rotation are ensured. In addition, the split structure design is adopted, the open structure is added to the side surface of the positioning shell 102, and in the state that the first limiting piece 1011 and the first annular protrusion 102 abut, the first limiting piece 1011 on the main body part 101 forms axial positioning on the first annular protrusion 201 on the rotating shaft 200 at the position of the open structure. While realizing the function of the rotating shaft of the earphone, it can be adjusted as needed at different assembly stages, improve the flexibility of product assembly, and reduce the complexity of product assembly.

[0038] In the present embodiment, after the main body part 101 and the rotating shaft 200 in the shell 100 are connected with the positioning shell 102 through the first opening K1 and the second opening K2 respectively, the first limiting piece 1011 abuts against the first annular protrusion 201. In this way, the relative displacement of the rotating shaft 200 and the first limiting piece 1011 in the axial direction can be prevented, thereby improving the stability of the whole structure.

[0039] Figure 5 Another positioning shell structure diagram provided by the present embodiment is shown in FIG. 10B. Figure 5 The positioning shell 102 in the shell 100 can include a cylinder 1021 and a pin shaft 1022. The cylinder 1021 in the positioning shell 102 forms a positioning cavity C, a first opening K1 and a second opening K2. The first opening K1 is distributed on the outer side surface of the cylinder 1021, and the second opening K2 is distributed on the end surface connecting the cylinder 1021. The axial direction of the pin shaft 1022 in the positioning shell 102 intersects with the axial direction of the cylinder 1021, the first end of the pin shaft 1022 is connected with the cylinder 1021 at the first opening K1, and the pin shaft 1022 extends out of the positioning cavity C through the first opening K1. The main body part 101 is connected with the part of the pin shaft 1022 extending out of the positioning cavity C.

[0040] In this case, through the precise fit of the main body 101 and the pin shaft 1022, the assembly accuracy between the main body 101 and the positioning shell 102 is improved, so that the stable connection between the main body 101 and the positioning shell 102 can be ensured, and the shaking or loosening that may occur during the use of the earphone 000 is reduced, and the wearing comfort is improved.

[0041] Reference Figure 6 , Figure 6 is a schematic diagram of a main body structure provided by an embodiment of the present disclosure. The main body 101 in the earphone 000 is provided with a positioning hole M, wherein the second end of the pin shaft 1022 is in interference fit with the positioning hole M.

[0042] In this embodiment, the pin shaft 1022 and the positioning hole M are both two, and the two pin shafts 1022 and the two positioning holes M are oppositely arranged. In this way, through the interference fit of the pin shaft 1022 and the positioning hole M, the close connection between the main body 101 and the positioning shell 102 is ensured, and the stability of the structure of the earphone 000 is further enhanced.

[0043] In some embodiments of the present application, the second end of the pin shaft 1022 is connected to the positioning hole M on the main body 101 in the form of interference fit. Due to the close fit between the pin shaft 1022 and the positioning hole M and the stability provided by the cylinder body 1021 as a support structure, the positioning shell 102 can resist the influence of external vibration and impact and maintain long-term stable positioning effect.

[0044] Reference Figure 7 and Figure 8 , Figure 7 is a schematic diagram of a rotating shaft piece structure provided by an embodiment of the present disclosure, Figure 8 is a cross-sectional view of a positioning shell provided by an embodiment of the present disclosure. The first annular protrusion 201 in the rotating shaft piece 200 can have a notch slot N. The inner wall of the cylinder body 1021 is provided with a second limiting piece 1023, and the second limiting piece 1023 is matched with the notch slot N.

[0045] In the state that the rotating shaft piece 200 is arranged in the positioning cavity C, the first limiting piece 1011 and the second limiting piece 1023 are located on the same side of the first annular protrusion 201. In this embodiment, after the rotating shaft piece 200 in the earphone 000 is arranged in the positioning cavity C, when the rotating shaft piece 200 rotates relative to the positioning shell 102, the first annular protrusion 201 abuts against the side of the second limiting piece 1023 away from the second opening K2, so that the rotating shaft piece 200 and the positioning shell 102 are connected together.

[0046] Figure 9 is a cross-sectional view of an earphone provided by an embodiment of the present disclosure Figure 2 . Reference Figure 9The first limiting member 1011 and the second limiting member 1023 are oppositely arranged after the main body part 101 in the shell 100 is connected with the positioning shell 102. In this way, the first limiting member 1011 and the second limiting member 1023 can be in abutment with the side of the first annular protrusion 201 facing the second opening K2, so as to further improve the stability of the structure of the earphone 000.

[0047] As shown in Figure 7 and Figure 8 , the inner wall of the cylinder body 1021 in the positioning shell 102 is provided with a third limiting member 1024.

[0048] The side surface of the rotating shaft member 200 in the earphone 000 has a second annular protrusion 204, and the second annular protrusion 204 has a limiting groove J matched with the third limiting member 1024.

[0049] In the axial direction of the rotating shaft member 200, the first annular protrusion 201 and the second annular protrusion 204 are arranged at intervals, and the limiting groove J is close to the first annular protrusion 201.

[0050] In the circumferential direction of the rotating shaft member 200, the width of the limiting groove J is greater than the width of the third limiting member 1024; and the third limiting member 1024 is at least partially located in the limiting groove J.

[0051] In this way, during the rotation of the positioning shell 102 around the rotating shaft member 200, the third limiting member 1024 on the inner wall of the positioning cavity C in the positioning shell 102 can be in abutment with the second annular protrusion 204 in the limiting groove J. And in the circumferential direction of the rotating shaft member 200, the width of the limiting groove J is greater than the width of the third limiting member 1024, so as to ensure that the positioning shell 102 rotates within a fixed rotation range, thereby effectively limiting the relative rotation range between the shell 100 and the rotating shaft member 200.

[0052] In the embodiment, as shown in Figure 6 and Figure 7 , the rotating shaft member 200 in the earphone 000 has a cylindrical rotating shaft member body 202, and the first annular protrusion 201 and the second annular protrusion 204 protrude from the circumferential surface of the rotating shaft member body 202. The first limiting member 1011 in the main body part 101 can have an arc-shaped groove P, and the curvature radius of the arc-shaped groove P is equal to the curvature radius of the rotating shaft member body 202.

[0053] In some embodiments of the present application, since the curvature radius of the shaft member body 202 and the arc-shaped groove P match, during assembly, the shaft member 200 only needs to be inserted into the barrel 1021, and the first annular protrusion 201 and the second annular protrusion 204 are aligned with the corresponding limiting structures. This design reduces the adjustment steps and errors during assembly, and improves the assembly efficiency. Through precise matching design and optimized structure layout, the wear and impact between the shaft member 200 and the barrel 1021 are reduced. The first annular protrusion 201, the second annular protrusion 204, and the arc-shaped groove P work together to disperse the stress and load of the shaft member 200 during rotation or force.

[0054] Thus, after the shaft member 200 is arranged in the positioning cavity C through the second opening K2 and connected with the main body 101, the side surface of the shaft member body 202 can completely match the arc-shaped groove P on the first limiting member 1011, so that the shaft member 200 can be stably positioned in the positioning cavity C and smoothly slide during rotation.

[0055] As shown in Figure 6 and Figure 7 , the shaft member 200 in the earphone 000 can have a first through hole Q1 extending in the axial direction of the shaft member 200, and the side of the main body 101 facing the first opening K1 has a second through hole Q2. The first through hole Q1 and the second through hole Q2 are used to pass the earphone wire, so that the earphone wire is electrically connected with the sound generating unit arranged in the main body 101. In this way, through the design of the first through hole Q1 and the second through hole Q2, the earphone wire can pass along a predetermined path, avoiding the disorder of the cable, and making the cable layout more neat.

[0056] In some embodiments of the present application, the first through hole Q1 extending in the axial direction is arranged on the shaft member 200, and the second through hole Q2 is arranged on the side of the main body 101 facing the first opening K1, which effectively utilizes the limited space inside the earphone, so that the earphone wire can pass through the inside of the earphone in a more compact and orderly manner and be connected to the sound generating unit, simplifying the connection path of the earphone wire, enabling the earphone wire to directly and smoothly pass through and be connected to the sound generating unit, and reducing the design difficulty and manufacturing cost.

[0057] As shown in Figure 7 and Figure 9 , the first end of the shaft member 200 in the earphone 000 has a third annular protrusion 203. The ear hook 300 in the earphone 000 has an annular groove H. After the shaft member 200 is connected with the ear hook 300, the third annular protrusion 203 is at least partially located in the annular groove H.

[0058] In the embodiment, after the shaft member 200 is connected with the ear hook member 300, the third annular protrusions 203 are all located in the annular groove H. In addition, the third annular protrusions 203 and the annular groove H are both three, and the three third annular protrusions 203 are correspondingly arranged with the three annular groove H. In this way, the shaft member 200 can be firmly connected with the ear hook member 300 through the third annular protrusions 203.

[0059] In some embodiments of the present application, the third annular protrusions 203 are designed at the first end of the shaft member 200, and the annular groove H is correspondingly arranged on the ear hook member 300. When the shaft member 200 is connected with the ear hook member 300, the third annular protrusions 203 can be at least partially embedded in the annular groove H. This design forms a physical locking mechanism, effectively preventing the relative movement or loosening between the shaft member 200 and the ear hook member 300, thereby enhancing the stability of the connection.
