[0031] The embodiments of this application are described below with reference to the accompanying drawings. It can be understood that the technical features involved in the different embodiments described below can be combined with each other as long as they do not conflict with each other.

[0032] Firstly, referring to Figures 1 to 4 This application provides an earphone arm comprising a first cover 10 and a second cover 20. The first cover 10 has a first arc-shaped track structure; the second cover 20 has a second arc-shaped track structure, the curvature of which is consistent with that of the first arc-shaped track structure, and the two slide together, limiting the first cover 10 and the second cover 20 along a direction perpendicular to the sliding direction. One of the first cover 10 and the second cover 20 has a limiting groove 108, and the other has a locking assembly, which includes a rotating member 106 and a locking block 107. The rotating member 106 can drive the locking block 107 to rotate. When the locking block 107 rotates to a first position, the locking block 107 locks with the limiting groove 108, limiting the first cover 10 and the second cover 20 along the sliding direction. When the locking block 107 rotates to a second position, the locking block 107 unlocks from the limiting groove 108.

[0033] In this embodiment, both the first cover 10 and the second cover 20 are provided with a track structure. The two cover bodies utilize the arc-shaped track structure for guidance to achieve a sliding fit and to limit the movement perpendicular to the sliding direction, preventing misalignment or displacement of the first cover 10 and the second cover 20. Furthermore, the locking block 107 can lock with the limiting groove 108 to limit the first cover 10 and the second cover 20 along the sliding direction, preventing relative sliding and thus fixing them in place. This application offers convenient assembly, secure fixing, and requires no other tools, improving production efficiency and saving on fastener costs.

[0034] In addition, combined Figures 2 to 4 In this embodiment, the locking component cooperates with the limiting groove 108, which has a simple structure, is easy to operate, and locks firmly, further enhancing the connection effect between the first cover 10 and the second cover 20, and also helps to improve the efficiency of assembly and disassembly.

[0035] Specifically, refer to Figure 3 and Figure 4 The rotating member 106 is at least partially located on the outside of the second cover 20 and is drivenly connected to the locking block 107, that is, the rotating member 106 can drive the locking block 107 to rotate; the locking block 107 is located on the inside of the second cover 20 and corresponds to the limiting groove 108 of the first cover 10; more specifically, the limiting groove 108 is an arc-shaped groove with a deeper middle section. When the locking block 107 rotates to the middle of the limiting groove 108, the locking block 107 locks with the limiting groove 108, that is, the first cover 10 and the second cover 20 are locked together; when the locking block 107 rotates to disengage from the limiting groove 108, the two are unlocked, that is, the first cover 10 and the second cover 20 are unlocked together.

[0036] In some embodiments, refer to Figure 2 and Figure 3 The first arc-shaped track structure and the second arc-shaped track structure are respectively provided with locking parts. When the two slide to the preset position, the locking parts on the two engage with each other and limit the first cover 10 and the second cover 20 along the sliding direction.

[0037] In this embodiment, the locking parts on the first and second arc-shaped track structures are used to lock the first cover 10 and the second cover 20 in the sliding direction, thereby making the first cover 10 and the second cover 20 more firmly fixed and easy to disassemble without additional tools.

[0038] In some embodiments, refer to Figure 2 and Figure 3 The first arc-shaped track structure and / or the second arc-shaped track structure include a plurality of sub-protrusions 101, which are spaced apart along the sliding direction, and at least one sub-protrusion 101 is provided with a locking portion.

[0039] In this embodiment, a first arc-shaped track structure and a second arc-shaped track structure are proposed. Multiple sub-protrusions 101 are spaced apart to facilitate production and molding. It should be understood that the continuous distribution of the limiting protrusions of the first cover 10 and the limiting protrusions of the second cover 20 is also a desirable implementation method, which can also achieve the function of sliding guidance.

[0040] In some embodiments, refer to Figure 2 and Figure 3The first cover 10 and the second cover 20 have a sub-protrusion 101 on the inner surface of the corresponding cover sidewall, and the other cover 20 has a sub-protrusion 101 on the outer surface of the corresponding cover sidewall. The sub-protrusions 101 on the two covers abut against each other in a direction perpendicular to the sliding direction and limit the first cover 10 and the second cover 20 in a direction perpendicular to the sliding direction.

[0041] In this embodiment, the sub-protrusions 101 on the first cover 10 and the second cover 20 abut against and limit the movement along a direction perpendicular to the sliding direction, i.e., referring to... Figure 2 and Figure 3 The sub-protrusions 101 on the two are misaligned along the thickness direction of the cover, thereby achieving mutual sliding guidance and preventing the first cover 10 and the second cover 20 from shifting.

[0042] In some embodiments, refer to Figure 2 and Figure 3 The first cover 10 and the second cover 20 have a locking part, one of which is a locking notch 102 and the other is a locking protrusion 103. The locking protrusion 103 can engage with the locking notch 102.

[0043] In this embodiment, the locking protrusion 103 and the locking notch 102 are used to lock together, which is reasonable in design, simple in structure, and firm in connection. Moreover, the connection between the first cover 10 and the second cover 20 can be achieved without additional tools.

[0044] In some embodiments, refer to Figure 2 and Figure 3 Along the sliding direction, the sub-protrusions 101 and 103 with engagement notches 102 are provided with guide slopes 104; and / or, there are multiple engagement notches 102 and engagement protrusions 103, and multiple engagement notches 102 can be engaged with multiple engagement protrusions 103.

[0045] In this embodiment, the engaging protrusion 103 and the engaging notch 102 engage with each other. The engaging notch 102 is provided on the sub-protrusion 101. The sub-protrusion 101 with the engaging notch 102 and the engaging protrusion 103 are respectively provided with guide slopes 104, which facilitates engagement and assembly, making the assembly of the first cover 10 and the second cover 20 more convenient and requiring no additional tools. In addition, the multiple engaging notches 102 and engaging protrusions 103 engage with each other, further enhancing the connection effect of the first cover 10 and the second cover 20, making them firmly fixed and preventing separation due to bumps during use.

[0046] In some embodiments, refer to Figure 2 and Figure 3Along the sliding direction, one of the first cover 10 and the second cover 20 has a first sub-protrusion 1011 at its end, and the other has a corresponding first engaging protrusion 1031. The first sub-protrusion 1011 can engage with the first engaging protrusion 1031.

[0047] In this embodiment, the first sub-protrusion 1011 and the first engaging protrusion 1031 are located at one end along the sliding direction to position the sliding termination position; and the two engage with each other, thereby further promoting the fixing effect between the first cover 10 and the second cover 20.

[0048] In some embodiments, refer to Figure 5 The first cover 10 and the second cover 20 cooperate to form a receiving cavity. The earphone arm also includes a core 30, which is movably inserted into the receiving cavity.

[0049] In this embodiment, the core 30 is movably inserted into the accommodating cavity formed by the first cover 10 and the second cover 20, so that the headphone arm can be extended and retracted to facilitate length adjustment to suit different users.

[0050] In some embodiments, refer to Figure 5 The inner wall of the first cover 10 and / or the second cover 20 is provided with a wave groove 109, and the core 30 is provided with an elastic arm 301, which elastically abuts against the wave groove 109; and / or, the core 30 is provided with a scale line 302, which shows the size of the core 30 extending out of the receiving cavity.

[0051] In this embodiment, the core 30 elastically abuts against the wave groove 109 using the elastic arm 301, achieving a movement of the core 30 along the wave groove 109 with a certain damping force. This ensures that the external force applied to the core 30 must reach a certain level to allow it to extend and retract, preventing the core 30 from becoming too loose relative to the receiving cavity. This ensures both extendable design and structural stability. Furthermore, the core 30 is provided with scale lines 302 to display the length of the core 30 extending beyond the receiving cavity, allowing the user to intuitively adjust the extension size.

[0052] Secondly, embodiments of this application provide an earphone that includes the earphone arm of the first aspect. Therefore, the earphone of the second aspect possesses all the technical effects of the earphone arm of the first aspect, and its specific technical effects will not be elaborated further.

[0053] It should be noted that the headphones in this embodiment only present the structure related to the improvement points. Of course, they may also include other components, such as earcups, sound modules, etc. Other components will not be described here.

[0054] In particular, the term "and / or" in this application should be understood as follows:

[0055] In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.

[0056] In the second case, the term "and / or" between the last two of three or more subjects means including at least any one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject;

[0057] Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.

[0058] Finally, although the embodiments of this application have been described above in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the concept of this application, and such modifications and variations all fall within the scope of protection of this application.
