[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, an embodiment of the present application provides an electronic device, including:

[0034] A housing 10, wherein an antenna and a camera module are disposed inside the housing 10, a first opening is disposed on the housing 10, and the camera module faces the first opening;

[0035] A plastic decorative piece 21 connected to the housing 10, the plastic decorative piece 21 covers the first opening, and the plastic decorative piece 21 is provided with a lens accommodating hole corresponding to the camera module;

[0036] A metal decorative part 22 disposed on a side of the plastic decorative part 21 away from the housing 10;

[0037] A lens 23 disposed on a side of the metal decorative part 22 away from the plastic decorative part 21, the lens 23 covering the lens accommodating hole;

[0038] The metal decorative part 22 is provided with at least two second openings 221 , and the frequency of the radiation wave formed by each of the at least two second openings 221 does not overlap with the frequency of the antenna.

[0039] For example, optionally, in the embodiments of the present application, Figure 1 As shown, with the side facing the camera lens as the front side, the antenna is usually arranged on the upper side and the left side corresponding to the upper left corner of the shell.

[0040] It should be noted that, in the embodiment of the present application, at least two second openings are arranged on the metal decorative part, and the frequency of the radiation wave formed by each second opening does not overlap with the frequency of the antenna. In this way, when the metal decorative part is not grounded, the interference of the clutter generated by the metal decorative part to the antenna of the electronic device can be avoided.

[0041] It should be noted that the radiated wave formed by the second opening 221 mentioned in the embodiment of the present application refers to the different noises corresponding to the circumference of the second opening 221; in one implementation method, the main wave frequency of the radiated wave does not overlap with the frequency of the antenna; in another implementation method, not only the main wave frequency of the radiated wave does not overlap with the frequency of the antenna, but the frequency of its resonant wave (there may be first harmonics, second harmonics, etc.) also does not overlap with the frequency of the antenna; optionally, the frequency of the antenna mentioned in the embodiment of the present application can be understood as a frequency band range.

[0042] Optionally, in one implementation, the frequency of the radiation wave formed by the second opening 221 is determined by the wavelength, and the absolute value of the difference between the circumference of the second opening 221 and half of the wavelength is less than or equal to a preset value.

[0043] It can be understood here that: the wavelength can be determined by the circumference of the second opening 221, and the wavelength is related to the frequency of the radiation wave formed by the second opening 221, so that the relationship between the frequency of the radiation wave formed by the second opening 221 and the circumference of the second opening 221 can be deduced, and the value of one of the frequency of the radiation wave formed by the second opening 221 and the circumference of the second opening 221 can be determined as long as the value of one of the frequency of the radiation wave formed by the second opening 221 and the circumference of the second opening 221 is known, the value of the other can be determined.

[0044] It should be noted that, in the embodiment of the present application, the absolute value of the difference between the circumference of the second opening 221 and half of the wavelength is less than or equal to the preset value, which can be understood as the circumference of the second opening 221 is approximately equal to half of the wavelength; optionally, the frequency of the antenna of the electronic device is already determined, and the frequency of the radiation wave formed by the second opening 221 can be determined by the following formula:

[0045] Formula 1:

[0046] Formula 2:

[0047] Wherein, χ represents the circumference of the second opening 221; λ represents the wavelength; f represents the frequency of the radiation wave formed by the second opening 221; c represents the wave speed; a, ε r represents the preset value; in the above formulas 1 and 2, λ, c, a, ε r As long as the value of one of χ and f is known, the value of the other can be determined. Based on this, as long as the frequency of the radiated wave formed by the second opening 221 is set not to overlap with the frequency of the antenna, that is, the circumference of the second opening 221 can be determined if the frequency of the radiated wave formed by the second opening 221 is known.

[0048] In the existing design, the length of the antenna radiator of the metal decorative part excites the clutter signal falling within the 23# and 24# antenna bands, while in the embodiment of the present application, the metal decorative part is divided into at least two second openings, so that the resonance point of the metal decorative part itself (that is, the inherent resonant frequency of the metal decorative part itself) is changed, causing its resonance to shift to a higher frequency, and the clutter frequency band is moved out of the 23# and 24# antenna bands by reasonably designing the circumference of the second opening, so that it cannot cause significant performance interference to the antenna.

[0049] Optionally, in one implementation, the metal decorative piece 22 is disposed in the lens accommodating hole, and the shape of the metal decorative piece 22 matches the lens accommodating hole. That is, in the embodiment of the present application, the metal decorative piece 22 is buckled in the lens accommodating hole, and the shape of the metal decorative piece 22 changes with the change of the shape of the lens accommodating hole. When the lens accommodating hole is set to a circle, the metal decorative piece 22 is also set to a circle, when the lens accommodating hole is set to a square, the metal decorative piece 22 is also set to a square, and when the lens accommodating hole is set to a triangle, the metal decorative piece 22 is also set to a triangle.

[0050] Optionally, in one implementation, the metal decorative part 22 includes:

[0051] An annular receiving groove 222, wherein the lens 23 is covered and disposed in the annular receiving groove 222;

[0052] A connecting piece 223 connected to the annular receiving groove 222 divides the metal decorative piece 22 into at least two second openings 221 .

[0053] Optionally, the annular receiving groove 222 can be understood as a circle of mounting bosses provided on the annular housing, and the lens is placed on the mounting bosses. The connecting member 223 is made of metal, for example, Figure 1As shown, in one implementation, the connector 223 is X-shaped, dividing the metal decorative member 22 into four second openings 221, and the frequency of the radiation wave formed by each second opening is calculated separately, and does not overlap with the frequency of the antenna, such as Figure 2 As shown, the clutter generated by a large circular ring d1 of the metal decorative part falls within the antenna frequency band, which will interfere with the antenna. The large circular ring d1 is divided into four small rings d11, d12, d13 and d14 through a connector. The shapes of the four small rings d11, d12, d13 and d14 are different. Generally speaking, the shorter the length of the ring, the higher the corresponding frequency. The frequencies of the clutter generated by these four small rings are all outside the antenna frequency band, so as not to interfere with the antenna.

[0054] In the embodiment of the present application, the resonant frequency of the metal decorative part is changed by adjusting the circumference of the large circular ring, thereby avoiding affecting the frequency of the antenna.

[0055] Optionally, in a specific application case, if four second openings 221 are included, the size settings of the four small rings are specifically as follows:

[0056] The circumference of the ring corresponding to d11 is 42.2 millimeters (mm);

[0057] The circumference of the ring corresponding to d12 is 30 mm;

[0058] The circumference of the ring corresponding to d13 is 47mm;

[0059] The circumference of the ring corresponding to d14 is 25mm.

[0060] It should be noted that the embodiment of the present application takes the example of a connector dividing the metal decorative part 22 into four openings, which does not constitute a limitation to the embodiment of the present application, and the shape of the openings in the figure is only an example. Any implementation method with more than or equal to two openings falls within the protection scope of the embodiment of the present application.

[0061] Optionally, further Figure 3 and Figure 4 As shown, the plastic decorative part 21 is provided with a boss 211 corresponding to each second opening 221 , and the boss 211 is fitted with the lens 23 through the second opening 221 .

[0062] Optionally, at least one of the at least two bosses 211 is provided with a hole, and each hole corresponds to a lens. It should be noted that the shape of the boss 211 corresponds to the shape of the second opening.

[0063] Optionally, in one implementation, the distance between the first side surface of the boss 211 and the lens 23 is greater than the distance between the first side surface of the connector 223 and the lens 23;

[0064] The first side surface is a side close to the lens 23 .

[0065] It should be noted that, in the embodiment of the present application, the height of the boss 211 is set to be slightly higher than the height of the connecting piece 223, and the boss 211 is fixedly connected to the lens 23 by means of double-sided tape 30, so that the connecting piece 223 can be surrounded between the lens 23 and the boss 211, and each of the second openings is surrounded on all sides, thereby blocking the water inlet path and realizing a waterproof design. Through this form of waterproof design, it is ensured that external water cannot flow into the interior of the shell through the gaps in the metal decorative parts, etc., thereby avoiding the problem of water ingress into the shell.

[0066] It should be noted that, since the side wall of the connector 223 provided on the metal decorative member 22 is close to the camera module, static electricity may be discharged to the camera module through the connector 223, causing damage to the camera module. Optionally, in one implementation, Figure 5 As shown, the plastic decorative part 21 of the embodiment of the present application is provided with a third opening 212, and the third opening 212 is provided at a position corresponding to the metal decorative part 22 except the second opening 221, and the third opening 212 is provided opposite to the metal part for static discharge in the housing 10. In the embodiment of the present application, the third opening 212 is provided at a position opposite to the connecting part on the plastic decorative part 21, and a metal part (such as a mainboard bracket steel sheet) is exposed in the housing 10 (such as a corresponding mainboard bracket area), so that static electricity can be discharged and grounded through the third opening 212 to avoid damaging the camera module.

[0067] Optionally, the metal decorative part 22 in the embodiment of the present application is ungrounded, that is, the embodiment of the present application can address the problem that the conventional ring-shaped ungrounded solution cannot solve the metal decorative part's clutter interference antenna, and proposes an ungrounded metal decorative part with a connecting part, thereby ensuring that the metal decorative part does not generate clutter interference antenna without grounding. Compared with the conventional grounding solution of the pancake-shaped metal decorative part, the ungrounded metal decorative part in the embodiment of the present application has lower design cost and better space design.

[0068] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
