In addition, the whole welding process is complex, and the welding spot is easy to fall off because the battery needs to be plugged into the lug rod cylinder after being welded. In addition, the main circuit board needs to be pulled out of the ear rod cylinder by a certain length before welding, and the battery and the main circuit board are pushed into the ear rod cylinder after welding, so that the main circuit board needs to be designed with redundant length and occupies the internal space of the ear rod cylinder. Also, the welding operation does not have a flat welding operation surface, resulting in poor reliability of welding.

In order to solve the above problems, embodiments of the present application provide an earphone, which can implement assembly and welding of a battery assembly and a main circuit board in an earphone barrel in a compact structural space, and insulate heat by using a heat insulation support in a welding process, so as to prevent heat generated in the welding process from affecting battery performance, and eliminate potential safety hazards.
