In addition, five connection holes are provided on the circuit board, and each connection segment 33 extends into the corresponding connection hole, and the welding pad is provided in the connection hole for welding with the connection segment 33 .

The manufacturing method of the earphone holder 100 according to the embodiment of the present utility model will be described below with reference to FIGS. 1-11 .

The earphone holder 100 according to the embodiment of the present invention is the above-mentioned earphone holder 100, and the manufacturing method includes:

S10: clamping the first pin 31 and the second pin 32 on the support frame 2 to form a bracket assembly;

S20: Insert the bracket assembly into the installation cavity 12 from the rear end of the installation cavity 12 .

S30: Filling an adhesive layer between the support frame 2 and the shielding cover, and between the housing 1 and the shielding cover.

The following describes a mobile terminal 1000 according to an embodiment of the present invention with reference to FIGS. 1-11 .

The mobile terminal 1000 according to the embodiment of the present invention includes the above-mentioned earphone holder 100. By setting the above-mentioned earphone holder 100, the tails of multiple pins 3 can be connected to the same circuit board, which can not only simplify the structure of multiple pins 3, It can also reduce the number of circuit boards, simplify the structure of the earphone holder 100, reduce the volume of the earphone holder 100, and facilitate the installation of the earphone holder 100.

In some embodiments of the present utility model, the mobile terminal 1000 may be a mobile phone, a tablet computer, or a notebook computer.
