In a specific embodiment, the weld 20 includes an axis, the first projection 23 is disposed about the axis, and the first projection 23 is rectangular in cross-section. Specifically, the welded portion 20 is formed by turning, that is, the welded portion 20 is in a solid of revolution structure, so the welded portion 20 is circumferentially arranged with the axis as a reference; the first protruding portion 23 may be an interference rib position set by the welding portion 20 during turning forming, and is annular and rectangular in section; meanwhile, in the present embodiment, the number of the first protruding portions 23 is one; in other alternative embodiments, the number of the first protruding portions 23 may be two, three, or other numbers, that is, a plurality of annular first protruding portions 23 may be provided on the first end portion 21. In other alternative embodiments, the first protruding portion 23 may be machined in other manners, for example, the first protruding portion 23 may be formed by milling, where the first protruding portion 23 may not be annular, and may be a protrusion extending along the axis of the first end 21.

Further, the welding portion 20 is further formed with a second protruding portion 24, and the second protruding portion 24 is disposed outside the mounting groove 11 and between the first end portion 21 and the second end portion 22. Wherein, the second protruding portion 24 can be formed on the welding portion 20 by turning, and serves as a positioning component of the split earphone charging pad structure, so that the split earphone charging pad structure is integrally installed in the earphone.

Further, the first end 21 abuts against the bottom of the mounting groove 11, and a gap is left between the second protruding portion 24 and the stainless steel mounting portion 10. By way of example, a gap of 0.1mm is left between the stainless steel mounting portion 10 and the second protruding portion 24, so that after the welding portion 20 is connected with the stainless steel mounting portion 10, the end face of the first end portion 21 is abutted to the bottom of the mounting groove 11, so that the inner surface of the stainless steel mounting portion 10 can be strongly supported, the split earphone charging pad structure cannot be deformed when being pressed, and stability of the split earphone charging pad structure is improved.

Further, a first chamfer 12 is formed at the notch edge of the mounting groove 11.
