[0046] The earphone assembly provided in the embodiment includes a rechargeable earphone and a charging box for accommodating the rechargeable earphone.

[0047] Referring to Figs. 1-3 The rechargeable earphone includes an earphone shell 1, a main board 2, a charging column 3 and an elastic clamping part 4.

[0048] The earphone shell 1 includes a front shell 101 and a rear shell 102 that surround a content storage cavity. The main board 2 is located in the content storage cavity. The elastic clamping part 4 is welded and fixed on the main board 2 for supplying power to the main board 2. The end face of one end of the charging column 3 is exposed outside the earphone shell 1 to be electrically connected with a power supply probe of the charging box. The other end of one end of the charging column 3 extends into the content storage cavity and elastically abuts against the elastic clamping part 4 to electrically connect the power supply probe to the main board 2, so that the charging box can charge the rechargeable earphone.

[0049] The elastic clamping part 4 comprises two oppositely arranged inclined elastic sheets 401, and the distance between the two inclined elastic sheets 401 gradually decreases from the first end to the second end to form a V-shaped space 402 for inserting the charging column 3.

[0050] Before the charging column 3 is inserted into the V-shaped space 402, the distance a between the first ends of the two inclined elastic sheets 401, the diameter b of the part of the charging column 3 inserted into the V-shaped space 402, and the distance c between the second ends of the two inclined elastic sheets 401 satisfy a >= b > c.

[0051] The charging earphone and the earphone assembly provided by the embodiment are characterized in that the V-shaped space 402 for inserting the charging column 3 is arranged between the two inclined elastic sheets 401, the distance a between the first ends of the two inclined elastic sheets 401 is greater than the diameter b of the part of the charging column 3 inserted into the V-shaped space 402, the larger opening size a provides sufficient clearance, allowing the charging column 3 to smoothly enter without complete alignment, thereby reducing the assembly difficulty and improving the assembly convenience and success rate, and the distance c between the second ends of the two inclined elastic sheets 401 is less than the diameter b of the part of the charging column 3 inserted into the V-shaped space 402, so that the two inclined elastic sheets 401 can tightly abut against the charging column 3 after the charging column 3 is inserted into the V-shaped space 402, thereby realizing good contact and ensuring the reliability of the electrical connection.

[0052] Therefore, the charging earphone and the earphone assembly provided by the embodiment can effectively solve the problem of large alignment difficulty of the elastic clamping part 4 and the charging column 3 of the existing wireless earphone, thereby improving the assembly yield and reducing the production cost.

[0053] Optionally, the elastic clamping part 4 further comprises a U-shaped frame connecting the two inclined elastic sheets 401. Specifically, the U-shaped frame comprises a transverse bottom plate 403 and two longitudinal connecting plates 404. The transverse bottom plate 403 is arranged in a spaced manner with the second ends of the two inclined elastic sheets 401, and each end of the transverse bottom plate 403 is connected to the first end of one of the two inclined elastic sheets 401 through one of the longitudinal connecting plates 404.

[0054] Further, the surfaces of the two inclined elastic sheets 401 close to each other are provided with limiting bosses 4011 for limiting the charging column 3 from sliding towards the first end. After the charging column 3 is inserted into the V-shaped space, the charging column 3 is located below the limiting bosses 4011, thereby limiting the charging column 3 from being separated from the elastic clamping part 4 through the opening of the first end under the elastic action of the inclined elastic sheet 401.

[0055] In this embodiment, the charging column 3 includes a first column 301 abutting against the elastic clamping part 4 (the diameter of the first column 301 is the diameter b of the part of the charging column 3 inserted into the V-shaped space 402), and a second column 302 located at the end face of the first column 301, wherein the diameter of the first column 301 is larger than the diameter of the second column 302.

[0056] Correspondingly, the outer surface of the rear shell 102 is provided with an outer containing groove 1021 for accommodating the second column 302, and the groove bottom of the outer containing groove 1021 is provided with a communication hole 1022 communicating the inner containing cavity and the outer containing groove 1021 and allowing the first column 301 to pass through.

[0057] When assembling, the elastic clamping part 4 can be first welded and fixed on the main board 2, then the assembly of the main board 2 and the earphone shell 1 is completed, and finally the charging column 3 is inserted into the V-shaped space through the communication hole 1022. Using the assembly method of first welding and fixing the elastic clamping part 4 on the main board 2 can bring significant advantages in the subsequent assembly process. This step ensures the accurate position of the elastic clamping part 4 on the main board 2, avoids additional adjustment of the elastic clamping part 4 during the assembly of the earphone shell 1, and simplifies the overall assembly steps. Such a process not only improves the assembly efficiency and reduces the operation difficulty, but also improves the product yield due to the stability of the fixed parts. In addition, this assembly method facilitates automated production, reduces manual intervention, improves production efficiency, and enhances the stability and durability of the product. Overall, this assembly method brings convenience to the production of electronic products such as wireless earphones, ensures product quality, and improves production efficiency.

[0058] Optionally, the first column 301 is provided with a tapered boss 303 for limiting the first column 301 from being pulled out of the communication hole 1022. The tapered boss 303 limits the movement of the charging column 3 in the axial direction (i.e. the direction of insertion or pulling out), thereby maintaining the stability of the charging column 3, and can also play a guiding role during assembly, helping the operator to more accurately position the charging column 3, reducing the alignment error, and improving the assembly efficiency.

[0059] In summary, the chargeable earphone and earphone assembly provided by the embodiment have the following advantages:

[0060] ① Reduce assembly difficulty: by designing the V-shaped space 402 and appropriate size relationship (a≧b>c), the charging column 3 can be smoothly inserted without accurate alignment, thereby reducing the assembly difficulty, improving the success rate of assembly and the yield of products;

[0061] 2. Ensure the reliability of the electrical connection: the inclined elastic sheet 401 can be tightly abutted after the insertion of the charging column 3, ensuring good electrical connection and improving the reliability of the product;

[0062] 3. Simplify the assembly process: the elastic clamping part 4 is first welded and fixed on the main plate 2, avoiding additional adjustment during the assembly of the earphone shell 1, simplifying the assembly steps and improving the assembly efficiency;

[0063] 4. Enhance the stability and durability of the product: the fixed elastic clamping part 4 and the structure design of the conical boss 303 improve the stability and durability of the product.

[0064] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, they do not limit the scope of the patent protection of the present application.
