These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0029] Figure 1 is a front view schematic diagram of an electronic device according to an exemplary embodiment. Figure 2 yes Figure 1 A schematic diagram of a side view of an electronic device in FIG. Figure 1 and Figure 2 As shown, the electronic device includes a frame 1, a screen 2, a dustproof net 3 and a handset (not shown), the frame 1 is connected to the screen 2, for example, the screen 2 and the frame 1 can be bonded by glue, the frame 1 can include a middle frame and a back cover, or the frame 1 can be an integrated structure of the middle frame and the back cover. The dustproof net 3 is arranged between the frame 1 and the screen 2, for example, the dustproof net 3 can be fixed relative to the screen 2 and the frame 1 by waterproof glue. For example, the screen 2 may include a depression, and the dustproof net 3 may be partially located in the depression and partially located between the screen 2 and the frame 1. The handset is located inside the electronic device, and the sound outlet of the handset is arranged toward the dustproof net 3, and the sound outlet direction of the sound outlet can be substantially parallel to the thickness direction of the electronic device, so that when the user holds the electronic device for a call, the sound can be directly directed toward the user's face, which is conducive to improving the privacy of the electronic device. Of course, in other embodiments, the sound outlet direction of the sound outlet can be perpendicular to the thickness direction of the electronic device, and the present disclosure does not limit this.

[0030] Based on this, the earpiece of the electronic device can emit sound through the dustproof net 3 set on the screen 2. The sound emitted by the earpiece is basically emitted toward the screen, and is basically emitted toward the user's ear when the user answers the call, which is conducive to improving the privacy of the electronic device, and the dustproof net 3 can block foreign matter and increase the dustproof effect. Among them, the dustproof net 3 can be located in the center of the edge of the screen 2, so that the aesthetics of the electronic device can be improved. In some embodiments, the dustproof net 3 can be located at the top of the electronic device, so that the sound emitted by the earpiece can be transmitted through the dustproof net 3 on the top of the electronic device. When the user uses the earpiece mode to answer the call, the sound can be directly transmitted to the user's ear, reducing the sound exposure and improving privacy. Of course, the dustproof net 3 can also be set on any side of the edge of the screen 2, or the dustproof net 3 can also be set on the side or bottom of the electronic device. It can be designed as needed, and the present disclosure does not limit this.

[0031] Furthermore, the frame 1 includes a radiating branch 11 stacked with the dustproof net 3, that is, in the thickness direction of the electronic device, the dustproof net 3 and the radiating branch 11 are stacked, and the interval between the radiating branch 11 and the dustproof net 3 is X, satisfying 0.15Z≤X≤0.2Z, wherein Z is the thickness of the electronic device, so as to facilitate the assembly of the screen 2 and the frame 1 and avoid interference between the dustproof net 3 and the radiating branch 11 of the frame 1.

[0032] In some embodiments, the dust-proof net 3 may be a soft dust-proof net, such as a plastic dust-proof net, a rubber dust-proof net or a silicone dust-proof net. The length of the dust-proof net 3 is not limited and can be designed according to requirements. In other embodiments, the dust-proof net 3 may include a metal dust-proof net, which is coupled with the radiation branch 11 in a working state to generate electromagnetic waves covering the target frequency band. The coupling of the metal dust-proof net with the radiation branch 11 can also improve the radiation performance of the radiation branch 11. The metal dust-proof net may be a full metal dust-proof net or a semi-metal dust-proof net, wherein the semi-metal dust-proof net can be understood as a dust-proof net containing a metal material, such as the semi-metal dust-proof net includes a metal strip and a plastic part connected to the metal strip, and the metal strip may be an exposed setting or a wrapped setting. The metal strip may be arranged in parallel with the radiation branch 11, which is conducive to the coupling of the metal strip with the radiation branch 11 to form a ring current.

[0033] In the direction perpendicular to the thickness of the electronic device, the length of the radiation branch L1 = 1 / 4λ ε , the length of the dust screen 3 meets 1 / 8λ ε ≤L2≤1 / 2λ n ,in, Where f0 is the operating frequency of the radiation branch, is the dielectric constant of the plastic of the electronic device, and c is the propagation speed of electromagnetic waves in the air. When the length L2 of the dustproof net 3 is within the above range, the performance of the radiation branch 11 can be well improved. Among them, the dustproof net 3 can be set as a dustproof strip structure, and the length direction of the dustproof strip is perpendicular to the thickness direction of the electronic device, that is, the length direction of the dustproof strip is the same as the length direction of the radiation branch 11, which is conducive to the coupling current on the dustproof net 3 flowing in the same direction, thereby forming a ring current with the radiation branch 11.

[0034] For example, the length of the dust screen 3 is equal to the length of the radiation branch 11. Figure 3 As shown, when the radiation branch 11 is in working state, the dust screen is coupled with the radiation branch 11, and the current on the dust screen 3 forms a ring current with the radiation branch 11, thereby forming coupled radiation. Based on this embodiment, the sky efficiency simulation is performed, and the following is obtained: Figure 4 The antenna efficiency curves are shown. Curve S1 is the efficiency curve of the radiation branch 11 when the dust screen is not set, and curve S2 is the efficiency curve when the dust screen 3 is coupled with the radiation branch 11. Comparing curves S1 and S2, the efficiency of the antenna is improved in the frequency band of 3.3GHz-4.8GHz, and the maximum improvement can be about 1.8dB.
