It should be noted that the material of the housing 50 of the embodiment of the present application is not limited to this, and other manners may also be adopted, such as: the housing 50 may be a plastic housing. Also for example: the housing 50 may be a ceramic housing. For another example: the housing 50 may include a plastic portion and a metal portion, and the housing 50 may be a housing structure in which metal and plastic are matched with each other. Specifically, the metal part may be formed first, for example, a magnesium alloy substrate is formed by injection molding, and then plastic is injected on the magnesium alloy substrate to form a plastic substrate, so as to form a complete housing structure.

In some embodiments, an antenna radiator may be formed on the middle frame 20. The antenna radiator may be used to radiate a wireless signal outward or to receive a wireless signal transmitted from another device (e.g., a base station).

In some embodiments, referring to fig. 4, fig. 4 is a schematic structural diagram of a middle frame assembly 60 provided in the embodiments of the present application. The middle frame assembly 60 includes a substrate 61, a metal frame 62, and a gap 63.

The substrate 61 may have a thin plate-like or sheet-like structure. In some embodiments, the substrate 61 may have a hole or a groove formed thereon. Holes or slots formed in the substrate 61 may be used to mount other electronic components of the electronic device 100. For example, electronic components such as a camera, a circuit board, and the like of the electronic apparatus 100 may be mounted on the substrate 61 through holes or slots. The material of the substrate 61 may include metal or plastic. For example, the substrate 61 may be an aluminum alloy substrate.

Wherein the first portion 631 is positioned on the metal frame 61, and the first portion 631 penetrates the metal frame 631. Thus, the first portion 631 divides the metal bezel 62 into at least a first metal part 621 and a second metal part 622. The first and

second metal parts

621 and 622 are spaced apart from each other at the first portion 631 of the slit 63. The other end of the first metal part 621 and the other end of the second metal part 622 may be connected together.

The second and

third parts

632 and 633 of the gap 63 are located between the substrate 61 and the metal frame 62, and the second and

third parts

632 and 633 are located at two sides of the first part 631, respectively. For example, the second portion 632 corresponds to the position of the second metal part 622, and the third portion 633 corresponds to the position of the first metal part 621. Thus, a position of the first metal part 621 corresponding to the third portion 633 of the slit 63 may form a tip. The second metal portion 622 may also form a tip at a position corresponding to the second portion 632 of the slit 63. The tip of the first metal part 621 and the tip of the second metal part 622 may form an antenna radiator, respectively.

In some embodiments, the antenna radiators formed on the first metal part 621 and the second metal part 622 may be respectively used for transceiving at least one of a radio frequency signal, a satellite positioning signal (e.g., a GPS signal), and a wireless fidelity signal (WiFi signal). At this time, the first metal part 621 and the second metal part 622 of the middle frame assembly 60 respectively form antenna radiators for transmitting and receiving wireless signals, so that the middle frame assembly 60 may be formed as an antenna assembly.

In some embodiments, the antenna radiators formed on the first metal part 621 and the second metal part 622 may be grounded, respectively. For example, the antenna radiators formed on the first metal part 621 and the second metal part 622 may be respectively connected to grounding points on the circuit board 30 of the electronic device 100 to realize grounding.

It should be noted that the sending and receiving of the wireless signal may include at least one of receiving the wireless signal, transmitting the wireless signal, and simultaneously receiving and transmitting the wireless signal.

The middle frame assembly 60 may form an antenna radiator through the first metal part 621 and the second metal part 622, and transmit and receive wireless signals through the formed antenna radiator, so that the electronic device 100 may stably transmit and receive wireless signals without separately providing an antenna radiator in the electronic device 100, and thus, communication stability of the electronic device 100 may be improved.
