The metal material is set the same, the preparation process is the same, the operation is convenient, and silver paste is used, which is low in cost. In some other embodiments, the metal filled in the via 104 is different from the metal type formed by the inner surface conductive area 102. In some embodiments, the aperture range of the via 104 is 1mm-2mm. In some embodiments, the aperture of the via 104 can be 1mm or 2mm. The aperture size of the via 104 should not be set too large or too small. If it is set too large, the amount of metal filled in the via 104 is large, the cost is high, and the process requirements are also high. If it is set too small, the amount of metal filled in the via 104 is small, and the stability of the electrical connection is affected. Therefore, in some embodiments, the aperture size of the via 104 is set appropriately to reduce costs while ensuring the stability of the electrical connection relationship.

[0053] In actual application, the outer surface conductive area 101 and the inner surface conductive area 102 of the shell 10 can be the printing area of ​​the PDS process. The outer surface conductive area 101 of the shell 10 can be located on the outer side wall of the shell 10, and the inner surface conductive area 102 of the shell 10 can be located on the inner side wall and the inner bottom wall of the shell 10. The inner and outer surfaces of the shell 10 are filled with silver paste into the via 104 through the PDS process to make the outer surface conductive area 101 and the inner surface conductive area 102 formed with metal conductive conductive area 101 conductive. During assembly, the middle frame 20 outside the shell 10 is spot welded with the first connecting member 40 (spring sheet structure) to form a whole. After the entire middle frame 20 and the spring sheet structure are assembled from top to bottom to the flange 103 of the shell 10, the first connecting member 40 (spring sheet structure) is interfered with the outer surface conductive area 101 with metal provided on the outer side wall of the shell 10 for contact conduction. Similarly, the circuit board 30 inside the shell 10 and the second connector 50 (mounting structure) patch form a whole. After the entire circuit board 30 and the mounting structure are assembled from top to bottom to the inner bottom wall of the shell 10, the second connector 50 (spring structure) is interfered with and contacted with the metal inner surface conductive area 102 provided on the inner bottom wall of the shell 10 to achieve conduction, thereby achieving conduction between the middle frame 20 and the circuit board 30 to realize the GPS circularly polarized antenna. The above-mentioned middle frame 20 can not only serve as a radiator of the antenna of the wearable device, but also as an external decorative part of the wearable device. The middle frame 20 uses the first connector 40, the metal electrical connection area provided on the inner and outer surfaces of the shell 10, and the second connector 50 to achieve electrical connection between the middle frame 20 and the circuit board 30. In this way, the antenna structure formed is less dependent on the middle frame 20, and the waterproof is reliable through the PDS via process. The structure of the wearable device 1 is simple and the cost is low. Compared with the related art, the middle frame 20 of the present application has a simple structure and low processing cost. The entire middle frame 20 is used as a decorative part to form a circularly polarized satellite positioning antenna, which has better performance than the previous GPS solution with partially attached flexible circuit boards or assembled steel sheets inside the plastic machine.
