Referring to fig. 3 to 6, fig. 6 is a schematic structural diagram of a wristwatch body 1000 according to an embodiment of the application, in which a second module 200 is fixed to a first module 100. Specifically, the first mounting portion 111 and the main board 210 are both provided with threaded holes, and the first fastener is a threaded fastener. When assembled, the battery 220 is adhered and fixed to the main board 210, and then the threaded fastener passes through the threaded hole of the main board 210 and the threaded hole of the first mounting portion 111, so as to fix the main board 210 to the first mounting portion 111, thereby realizing the detachable connection of the second module 200 to the first module 100.

The first mounting portions 111 and the second mounting portions 112 are each plural, and as shown in fig. 5, each first mounting portion 111 is located at an upper end of the upper case 110, and each second mounting portion 112 is located at least partially at a lower end of the upper case 110.

In another embodiment, only one first mounting portion 111 and only one second mounting portion 112 may be provided, and the first mounting portion 111 and the second mounting portion 112 are both in a ring structure, and the length of the first mounting portion 111 extending laterally toward the inner side of the upper case 110 is longer than that of the second mounting portion 112, so that the main board 210 may be placed into the upper case 110 from the end of the first module 100 having the second mounting portion 112, and the main board 210 may be fixed to the first mounting portion 111, and the first fastener may not be interfered by the position of the second mounting portion 112, so that the first fastener may pass through the threaded hole of the main board 210 and the threaded hole of the first mounting portion 111.

In another embodiment, the first mounting portion 111 and the main board 210 may be provided with light holes, and the first fastener may be a press-type fastening fastener, and the press-type fastening fastener may be pressed into the holes of the main board 210 and the first mounting portion 111, so as to fix the main board 210 to the first mounting portion 111.

The bottom case 310 and the second mounting portion 112 may each be provided with a threaded hole, and accordingly, the second fastener may be a threaded fastener. The bottom case 310 and the second mounting portion 112 may each be provided with a light hole, and accordingly, the second fastener may be a push-type snap fastener. As shown in fig. 5, the second mounting portion 112 extends from the lower end of the upper case 110 to the upper end of the upper case 110 such that the second mounting portion 112 is longer in size in the longitudinal direction Z. It will be appreciated that the second mounting portion 112 may also be located only at the lower end of the upper case 110, i.e. the dimension of the second mounting portion 112 in the longitudinal direction Z may be shorter than in the previous case.

Component 230 may be one or more of a single chip, a bluetooth chip, a flash memory chip, a WIFI chip, and a GPS chip. Most of the electromagnetic field on the wristwatch body 1000 is generated by the component 230.

The electromagnetic shielding member 240 is used for shielding electromagnetic interference generated by the components 230 on the main board 210 in the use environment of the wristwatch body 1000 or electromagnetic interference generated by the components 230 on the main board 210 for the equipment in the use environment of the wristwatch body 1000, so as to satisfy electromagnetic compatibility. The electromagnetic shield 240 may be an integral structure, and may be fixed to the main board 210 by welding.

Therefore, the buzzer 2431 fixed to the electromagnetic shield 243 is electrically connected to the main board 210 via the elastic member, so that the electromagnetic shield 243 cannot be or is difficult to be engaged with the electromagnetic shield frame 242, or the buzzer 2431 cannot be electrically connected to the main board 210 can be reduced, and the reliability of the electrical connection between the buzzer 2431 and the main board 210 can be improved.

By fixing the buzzer 2431 to the electromagnetic shield 243, the empty space in the electromagnetic shield 243 is utilized, and the space occupation is reduced compared with the case where the buzzer 2431 is provided at the other positions. Since the buzzer 2431, the main board 210 and the battery 220 are integrated into one module, the integration level of the internal modules of the wristwatch body 1000 is improved. By fastening the electromagnetic shielding cover 243 to the electromagnetic shielding frame 242, the electromagnetic shielding cover 243 can be detached from the electromagnetic shielding frame 242, so that the first elastic member 250, the second elastic member 260, the component 230 or the buzzer 2431 fixed to the electromagnetic shielding cover 243 in the electromagnetic shielding frame 242 can be maintained and replaced.
