The sound assembly 100 includes a sound body 110 and a mounting ring 120. The mounting ring 120 is connected to the outer side of the sound body 110. The outer side of the mounting ring 120 is provided with an external thread structure 121. The battery assembly 200 is provided with a receiving groove 201. The inner peripheral wall of the receiving groove 201 is provided with an internal thread structure 211. The mounting ring 120 is located in the receiving groove 201. The external thread structure 121 is threadedly connected with the internal thread structure 211, so that the sound assembly 100 and the battery assembly 200 are detachably connected. The earphone structure 10 also includes a sealing ring 300. The sealing ring 300 is located in the receiving groove 201. The sealing ring 300 elastically abuts against the peripheral edge of the mounting ring 120 and the inner wall of the receiving groove 201, so that the sealing ring 300 seals the connection between the mounting ring 120 and the battery assembly 200.

[0033] like Figures 2 to 4 As shown, in this embodiment, when installing the earphone structure 10, one end of the mounting ring 120 is aligned with the receiving groove 201, and then the mounting ring 120 is rotated to make the external thread structure 121 and the internal thread structure 211 threadedly connected, and the mounting ring 120 is screwed into the receiving groove 201. After the mounting ring 120 is tightened, the sealing ring 300 elastically abuts against the periphery of the mounting ring 120 and the inner wall of the receiving groove 201. When the earphone structure 10 is disassembled, the mounting ring 120 is rotated to gradually screw out of the mounting ring 120, so that the sound assembly 100 is separated from the battery assembly 200.

[0034] In the earphone structure 10, the outer side of the mounting ring 120 is provided with an external thread structure 121, and the inner wall of the receiving groove 201 is provided with an internal thread structure 211. The external thread structure 121 is threadedly connected with the internal thread structure 211, so as to realize the threaded connection between the sound component 100 and the battery component 200. After tightening the mounting ring 120, that is, after the assembly of the sound component 100 and the battery component 200 is completed, the sealing ring 300 elastically abuts against the peripheral edge of the mounting ring 120 and the inner wall of the receiving groove 201, so that the sealing ring 300 seals the connection between the mounting ring 120 and the battery component 200, improves the sealing performance of the earphone, inhibits the adverse effects of external moisture and dust on the inside of the earphone, and prolongs the service life of the earphone. In addition, since the sealing ring 300 is located in the receiving groove 201, it is avoided that the sealing ring 300 is exposed to the outside, inhibits the problem of corrosion of the sealing ring 300 by external substances, and improves the sealing stability of the sealing ring 300.

[0035] like Figures 2 to 4 As shown, in one embodiment, the earphone structure 10 further includes a contact member 400 and a conductive member 500, wherein the contact member 400 is located in the mounting ring 120 and is electrically connected to the sound-emitting body 110, and at least a portion of the conductive member 500 is located in the receiving groove 201 and is electrically connected to the battery assembly 200, and the conductive member 500 is also electrically connected to the contact member 400. In this embodiment, when the external thread structure 121 is connected to the internal thread structure 211, and the sealing ring 300 is elastically abutted against the periphery of the mounting ring 120 and the inner wall of the receiving groove 201, respectively, the conductive member 500 is electrically connected to the contact member 400, so that the sound-emitting assembly 100 is electrically connected to the battery assembly 200, and the battery assembly 200 supplies power to the sound-emitting assembly 100.

[0036] like Figure 3 and Figure 4 As shown, in one embodiment, the contact member 400 is a solder pad, and the conductive member 500 is a spring pin. In this embodiment, after the sound component 100 and the battery component 200 are assembled, the spring pin abuts against the solder pad, thereby achieving electrical connection between the sound component 100 and the battery component 200.

[0037] In one embodiment, the contact member 400 is a pad, and the conductive member 500 is a spring. In this embodiment, after the sound component 100 and the battery component 200 are assembled, the spring abuts against the pad, thereby achieving electrical connection between the sound component 100 and the battery component 200.

[0038] In one embodiment, the conductive member 500 is a solder pad, and the contact member 400 is a spring pin. In this embodiment, after the sound component 100 and the battery component 200 are assembled, the spring pin abuts against the solder pad, thereby achieving electrical connection between the sound component 100 and the battery component 200.

[0039] In one embodiment, the conductive member 500 is a solder pad, and the contact member 400 is a spring. In this embodiment, after the sound component 100 and the battery component 200 are assembled, the spring abuts against the solder pad, thereby achieving electrical connection between the sound component 100 and the battery component 200.

[0040] Of course, in other embodiments, the sound assembly 100 and the battery assembly 200 may also be electrically connected via a wire or other existing connection structures.

[0049] 1. An external thread structure 121 is provided on the outer side of the mounting ring 120, and an internal thread structure 211 is provided on the inner wall of the receiving groove 201. The external thread structure 121 is threadedly connected with the internal thread structure 211 to realize the threaded connection between the sound component 100 and the battery component 200. After tightening the mounting ring 120, that is, after the assembly of the sound component 100 and the battery component 200 is completed, the sealing ring 300 elastically abuts against the peripheral edge of the mounting ring 120 and the inner wall of the receiving groove 201, so that the sealing ring 300 seals the connection between the mounting ring 120 and the battery component 200, thereby improving the sealing of the earphone, suppressing the adverse effects of external moisture and dust on the inside of the earphone, and extending the service life of the earphone.

[0050] 2. Since the sealing ring 300 is located in the receiving groove 201, the sealing ring 300 is prevented from being exposed to the outside, the problem of corrosion of the sealing ring 300 by external substances is suppressed, and the sealing stability of the sealing ring 300 is improved.
