The inner circumferential wall of each of the semi-cylindrical bodies is recessed inwardly to form a recess 242 that is adapted to the shape of the reset member 25. The reset member 25 is two semi-cylindrical magnets 25A, each of which is embedded in the recess 242, and an inner circumferential wall thereof constitutes an inner circumferential wall at the position of the recess 242 of the second insulating casing 24. The magnet 25 产生 generates a magnetic force to the stopper portion 281, and the magnetic force is smaller than the urging force of the resist member 23 to the ferrule 282. Therefore, the magnet 25 不能 can not absorb the ferrule sleeve 282 when the resisting member 23 pushes the ferrule sleeve 282, and can absorb the ferrule sleeve 282 when the ferrule sleeve 282 does not abut against the ferrule 280, so that the ferrule sleeve 282 and the ferrule When the core 280 is assembled separately, 'Firstly, the ferrule 280 and the ferrule sleeve 282 are placed in the body 221 of the first insulating housing 22, and the first ferrule sleeve 282 is fixed on the body 221' while the ferrule sleeve 282 is inserted. The opposite sides of the core 280; then, the two semicircular bodies of the fixing portion 220 are relatively fixed from the outer side of the ferrule sleeve 282 and fixed on the body 221, so that the flange 285 of the ferrule sleeve 282 limits the first insulating shell 22, the connecting portion 286 of the ferrule _282, the flange 287 and the plug portion 283 are located outside the first rotating edge 22; then, one end of the supporting member 23 is pivotally connected to the fixing portion by the opening On the stud 224 of the 220, at this time, the other end of the resisting member 23 is located in the circular hole 222 of the fixing portion 220 and pushes against the ferrule sleeve 282 to bring the ferrule sleeve 282 and the ferrule 280 together; then 'will operate The two semi-cylindrical members of the member 26 are butted from the outside of the connecting portion 286, so that the operating member 26 is sleeved on the connecting portion 286, and the operating member 26 is provided with a push. One end of the fixed portion 266 opposite 220, resist 23 is located two pushing member portions 268 between and through the aperture 266. Finally, the semi-cylindrical body of the second insulative housing 24 with the restoring member 25 is abutted from the outside of the limiting body 281, thereby 098127330 Form No. 1010101 Page 9/24 pages 0982046850-0 201106720 Second Insulation Housing 2 4 Limited between the operating member 26 and the flange 2 § 7. [0023] [0023] [0023] [0023] [0023] The ferrule 280 is affixed to the ferrule 282, and the ferrule 282 is spliced together, that is, the plug 28 is 2. 5mm as an initial state, the headset 50 is described. application. Referring to FIG. 7 and FIG. 8 again, when the plug 28 is used as a 3.5 mm plug, a force is applied to the operating member 26 to rotate the operating member 26 relative to the fixed portion 220 so as to be located on the operating member 26. The pushing portion 266 also pushes the resisting member 23 as the operating member 26 moves, while the operating member 26 urges the lug 223 to deform the lug 223 ''straight::聋_ is released by the lug 2 2 3 during rotation After the generation of a resistance effect. At this time, the resisting member 2 3 is blocked from the side of the pushing portion 266 away from the ferrule sleeve 282. Therefore, the abutting member 23 is released from the occlusion of the ferrule 282. At the same time, the ferrule sleeve 282 is adsorbed on the resetting member 25 under the magnetic force of the re-setting member 25, so that the core sleeve 2 8 2 and the plug 4 2 8 0 are separated from each other', that is, the cross section of the plug 28. The diameter is increased to match the audio interface of 3.5 mm. To restore the plug 28 to a 3.5 mm plug, a force is applied to the operating member 26 to rotate the operating member 26 relative to the fixed portion 220. At this time, the pushing portion 266 rotates with the operating member 26 while the operating member 26 The compression lug 223 deforms the lug 223 until it is subjected to a resistance effect caused by the release of the lug 223 during the rotation. At this time, the resisting member 23 is separated from the pushing portion 266. The elastic action of the re-setting body 230 on which the resisting member 23 is placed returns to the initial position and abuts against the ferrule sleeve 282 in the direction of the ferrule 280. Since the magnetic force of the top abutting force of the abutting member 23 is large, the insertion sleeve 282 is detached from the reset member 25, and is abutted against the ferrule 280 by the abutting member 23, that is, the plug 28 The diameter of the cross-sectional area is reduced to match the audio interface of 2. 5mm 098127330 Form No. A0101 Page 10 / Total 24 Page 0982046850-0 201106720. [0025] [0028] [0028] [0028] [0033] [0033] In the above embodiment, the ferrule 28 is configured to be composed of a semi-cylindrical body. The cylindrical body may be provided as a semi-cylindrical body composed of N 1/2 N cylindrical bodies. Accordingly, the abutting member 23, the returning member 25, and the pushing portion 266 can also be correspondingly provided in an amount corresponding to 1/2 N cylindrical bodies. The above-mentioned earphones can be converted into different specifications of the earphone plugs by driving components such as the operating member 26, the resisting member 23, the resetting member 25, the pushing portion 266, etc., so that the audio interface of different sizes can be connected by one earphone.
