The elastic member 225 can be a spring.

[0034] See also Figures 1 to 7 When the earphone battery tab welding fixing device of the present embodiment is used, the fixed pressing plate 3 is first rotated open from the fixing seat 1; then the fixed pushing block 222 is manually pushed to push the mounting seat 221 and the fixed pressing head 223 to slide and make way on the fixing seat 1, so as to facilitate the placement of the earphone main board and the battery 4 into the positioning groove of the positioning fixture 21; after the earphone main board and the battery 4 are placed into the positioning fixture 21, the fixed pushing block 222 is released, and the fixed pressing head 223 presses the tab 43 of the battery 42 onto the welding position of the earphone main board 41 through the elastic force of the elastic member 225; then the fixed pressing plate 3 is rotated closed from the fixing seat 1, and the earphone main board and the battery 4 are pressed into the positioning fixture 21; thus, the tabs 43 of the earphone main board 41 and the battery 42 to be welded are exposed from the exposure opening 31, and the tabs 43 of the battery 42 are welded to the earphone main board 41 through the welding equipment. After welding is completed, the fixed pressure plate 3 is rotated open from the fixing seat 1, and the fixed push block 222 is manually pushed to push the mounting seat 221 and the fixed pressure head 223 to slide on the fixing seat 1 to make way, and the welded earphone motherboard and battery 4 can be taken out of the positioning fixture 21 as a whole.
