In some embodiments, the non-display area 102 may include two areas located at the upper and lower portions of the display area 101.

In some embodiments, as shown in FIG. 2, the display screen 10 may be a full-face screen. At this time, the display screen 10 may display information in a full screen, so that the electronic apparatus 100 has a large screen occupation ratio. The display screen 10 includes only the display area 101 and does not include the non-display area. At this time, functional components such as a camera and a proximity sensor in the electronic apparatus 100 may be hidden under the display screen 10, and the fingerprint recognition module of the electronic apparatus 100 may be disposed on the back of the electronic apparatus 100.

The middle frame 20 may have a thin plate-like or sheet-like structure, or may have a hollow frame structure. The middle frame 20 can be accommodated in the accommodating space formed by the display screen 10 and the housing 50. The middle frame 20 is used for providing a supporting function for the electronic components or functional modules in the electronic device 100, so as to mount the electronic components or functional modules in the electronic device together. For example, functional components such as a camera, a receiver, a circuit board, and a battery in the electronic apparatus may be mounted on the center frame 20 for fixation. In some embodiments, the material of the middle frame 20 may include metal or plastic.

In some embodiments, the housing 50 may be a metal housing, such as a metal such as magnesium alloy, stainless steel, and the like. 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). At this time, the middle frame 20 and the antenna radiator formed on the middle frame 20 may constitute a middle frame assembly.

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.

The metal frame 62 is formed around the periphery of the substrate 61. For example, the metal frame 62 may be formed by a metal material surrounding the periphery of the substrate 61. The material of the metal frame 62 may include metal such as aluminum alloy and magnesium alloy. For example, in some embodiments, the metal bezel 62 may be a magnesium alloy metal bezel. The width of the metal bezel 62 may be between 2mm (millimeters) and 5 mm.

The slit 63 penetrates the middle frame assembly 60 in the thickness direction of the middle frame assembly 60. That is, the slit 63 is formed as a through hole in the middle frame member 60 when viewed from the outside. The gap 63 includes a first portion 631, a second portion 632, and a third portion 633. The third part 633, the first part 631 and the second part 632 are connected in sequence.

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.

The signal source L1 is connected to the antenna radiator P1. The signal source L2 is connected to the antenna radiator P2. The signal source L3 is connected to the antenna radiator P3. The signal source L4 is connected to the antenna radiator P4. The signal source L5 is connected to the antenna radiator P5. The signal source L6 is connected to the antenna radiator P6. The signal source L7 is connected to the antenna radiator P7.

In some embodiments, the signal sources L1, L2 are each configured to generate signals having frequencies in the range of 700MHz to 960MHz, 1710MHz to 2170MHz, 2300MHz to 2690MHz, i.e., LB, MB, HB. The signal source L3 is used to generate satellite positioning signals. The signal sources L5, L6 are both used to generate signals with frequencies ranging from 1710MHz to 2170MHz, 2300MHz to 2690MHz, i.e. MB, HB. The signal sources L4 and L7 are both used for generating wireless fidelity signals or radio frequency signals with the frequency range of 3399.5MHz to 3531 MHz.

In the signal sources L1, L2, L3, L4, L5, L6, and L7, the electronic device 100 may control some signal sources to operate, and control other signal sources not to operate. That is, the seven signal sources may not necessarily all be in operation at the same time.

In the antenna assembly, the antenna radiators P1 and P2 are used for receiving and transmitting LB, MB, and HB full-band radio frequency signals, the antenna radiators P5 and P6 are used for receiving and transmitting MB and HB radio frequency signals, and the antenna radiators P4 and P7 are simultaneously used for receiving and transmitting WiFi signals or 3.5G radio frequency signals, so that when one or more antenna radiators in the electronic device 100 are interfered by signals, the electronic device 100 can still receive and transmit wireless signals through other antenna radiators. For example, when the antenna radiator P1 is interfered by signals, the electronic device 100 may still transmit and receive full-band rf signals through the antenna radiator P2. Accordingly, the interference resistance of the electronic apparatus 100 can be improved, and the communication stability of the electronic apparatus 100 can be improved.
