[0029] The front shell 11 is designed with one or more first limiting portions 11a, and these through holes are used for installing bolts to achieve the detachable connection between the front shell 11 and the rear shell 2.

[0030] The rear shell 2 is designed with one or more second limiting portions 2a, and the second limiting portion 2a is coaxially arranged with the first limiting portion 11a of the front shell 11 to achieve detachable connection.

[0031] The first connecting member 31 is a bolt, the second connecting member 32 is a nut post, the first limiting portion 11a is a through hole, and the second limiting portion 2a is a threaded hole.

[0032] In the present utility model, the steps of installing the earphone 100 are as follows: First, place the battery 4 between the front shell 11 and the rear shell 2. Then, threadedly connect the second connecting member 32 with the first one. Next, align the first limiting portion 11a and the second limiting portion 2a coaxially. Finally, pass the first connecting member 31 through the first limiting portion 11a and threadedly connect it with the second connecting member 32 to fix the front shell 11 and the rear shell 2.

[0033] The steps of disassembling the earphone 100 are as follows: First, loosen the threaded connection between the first connecting member 31 and the second connecting member 32. Finally, separate the front shell 11 and the rear shell 2 and take out the battery 4.

[0034] In another way, the first connecting member 31 is a buckle; one end of the second connecting member 32 is a buckle and the other end is a buckle groove; the first limiting portion 11a is a through hole; the second limiting portion 2a is a buckle groove; the first connecting member 31 is inserted into the buckle groove of the second connecting member 32, and the buckle of the second connecting member 32 is inserted into the buckle groove of the rear shell 2, thus realizing the detachable connection of the earphone 100.

[0035] Users can easily disassemble the front shell 11 and the rear shell 2 of the earphone 100, which is convenient for replacing the battery 4 or repairing the internal components. By replacing the battery 4 instead of the whole earphone 100, the service life of the earphone 100 can be extended and electronic waste can be reduced. This design encourages the reuse and recycling of the battery 4, reducing the situation of discarding the whole earphone 100 due to the end of the battery 4's life, which conforms to the concept of sustainable development.

[0036] Please refer to Figure 5 and Figure 6 and Figure 7 , in an embodiment of the present utility model, a first threaded hole 32a is provided at one end of the second connecting member 32 close to the first connecting member 31, the first connecting member 31 is threadedly connected with the first threaded hole 32a, the second limiting portion 2a is a second threaded hole, and the thread direction of the second threaded hole is opposite to that of the first threaded hole 32a.

[0037] The first connecting member 31 is a bolt and the second connecting member 32 is a nut post.

[0038] In the present utility model, when the first connecting member 31 attempts to be screwed out of the first limiting portion 11a of the front shell 11, due to the opposite thread directions of its thread with the first threaded hole 32a of the second connecting member 32, a locking effect will be generated. That is, the attempt to screw out the first connecting member 31 will be hindered by the reverse thread of the second connecting member 32.

[0039] This design effectively prevents the second connecting member 32 from being accidentally taken out or falling off due to the interaction of the threads when the first connecting member 31 is screwed out, enhancing the stability of the overall structure. The reverse threads provide an additional anti-slip mechanism, ensuring a firm connection even in high-vibration or dynamic usage environments and reducing the risk of structural failure caused by thread slippage. By reducing the damage that may be caused to the threads during the conventional disassembly and assembly processes, the durability of each component and the service life of the product are improved.
