The grounding assembly 5 provided by the present disclosure is suitable for being installed between equipment components having coupling effects in electronic equipment, for example, may be disposed between an antenna component and an audio component to eliminate the coupling effects of the equipment components, or installed on equipment components having strong electric points to assist the equipment components in achieving grounding. Since the adapter part 51 of the grounding component 5 is formed into the groove-shaped structure y, when the grounding component 5 is arranged in the electronic device, only the space required by the middle adapter part 512 is reserved between the original device components, and the first grounding part 52 and the second grounding part 53 which are actually used for grounding are only required to be electrically connected with the first adapter part 511 and the second adapter part 513 of the adapter part 51 respectively, so that excessive change of the space distribution in the electronic device is not required, the space utilization rate of the electronic device is ensured, and meanwhile, the working performance of the original device components is not negatively influenced.

In some embodiments, referring to fig. 1, a first ground member 52 is attached to a side of the first adapter member 511 remote from the second adapter member 513, and a second ground member 53 is attached to a side of the second adapter member 513 remote from the first adapter member 511. In this way, the electrical connection area between the first grounding member 52 and the second grounding member 53 and the adapter 51 is ensured to be larger, the electrical connection effect is better, and meanwhile, the space required by the first grounding member 52 and the second grounding member 53 is ensured to be smaller, so that the space utilization efficiency of the electronic equipment is further improved.

In some embodiments, the adapter 51 is a sheet-like structure of conductive material; the first grounding element 52 or the second grounding element 53 is double-sided conductive foam. Based on the above arrangement, the space required by the grounding assembly can be effectively reduced, the cost is effectively reduced, and the grounding effect of the grounding assembly 5 is ensured.

Alternatively, the adapter 51 may be a conductive cloth. Based on this, the space occupied by the adapter 51 can be ensured to be smaller, which is beneficial to further improving the space utilization efficiency of the electronic device. Alternatively, the conductive cloth may be 7×8.5mm in size.

Alternatively, the size of the first grounding element 52 or the second grounding element 53 may be 6×1.5mm.

It should be noted that, the first grounding member and the second grounding member and the first switching member and the second switching member referred to in this disclosure are only used to distinguish between two grounding members and two switching members describing the grounding assembly, and do not mean that the structures or dimensions of the two grounding members or the two switching members are necessarily different or necessarily the same. In practice, the structures or dimensions of the two ground members or the two adapter members may be set to be the same or different depending on the arrangement space or the like in the electronic apparatus; when the two grounding members are identical in structure and size and the two adapter members are identical in structure and size, the installation direction of the grounding assembly relative to the audio assembly can be changed, and only the opening of the grounding assembly is required to be ensured to face the audio assembly. For example, when the first and second ground members 52 and 53 are identical in structure and size, and the first and second switching members 511 and 513 are identical in structure and size, either one of the first and second ground members 52 and 53 may be used for electrical connection with the metal back cover 1, and the other may be used for electrical connection with the screen steel plate 2.

In some embodiments, referring to fig. 3, the audio component 4 has a strong electrical point 46 and the ground component 5 is less than a second threshold from the strong electrical point 46.

It should be noted that the position of the strong electric point 46 in fig. 3 is merely illustrative, and the position may be changed based on different formation reasons of the strong electric point. In one case, the strong electrical point 46 of the audio component 4 is formed by coupling between the audio component 4 and the antenna component that is located closer to the mounting location. By setting the distance between the grounding element 5 and the strong electric point 46 to be smaller than the second threshold value, the grounding process of the strong electric point 46 by the grounding element 5 can be ensured, and the audio element 4 is prevented from being damaged.

In some embodiments, referring to fig. 2, the first and second adapters 511 and 513 of the adapter 51 are attached to opposite sides of the audio component 4, respectively;

In some embodiments, referring to fig. 2, the audio assembly 4 includes a sound cavity bracket 41, and the first and second adapters 511 and 513 are attached to opposite sides of the sound cavity bracket 41, respectively.

Based on the above arrangement, it is ensured that the ground assembly 5 is in contact with the sound cavity bracket 41 only, without affecting other elements in the audio assembly 4. For example, referring to fig. 2, a speaker placement site 45 may be formed in the audio component 4, a speaker 44 may be mounted within the speaker placement site 45, and the sound cavity bracket 41 encloses the speaker placement site 45. The grounding assembly 5 is arranged in the electronic device only by means of the sound cavity bracket 41, without affecting the normal operation of the speaker 44.

In summary, the audio component provided by the embodiment of the disclosure can be grounded by means of the grounding component, so that the audio component is not easy to be damaged by strong electricity, and the grounding component is not required to be excessively abdied, so that the working performance of the audio component is ensured to be better.

In the embodiment of the present disclosure, the antenna assembly 3 and the audio assembly 4 in the electronic device are arranged side by side between the screen steel plate 2 and the metal back cover 1. Because the current value of the antenna assembly 3 at the feeding point is larger, the audio assembly 4 which is closer to the antenna assembly 3 is easy to couple with the antenna assembly 3, absorbs the energy emitted by the antenna assembly 3, and reduces the performance of the antenna assembly 3. To eliminate this coupling effect, the presently disclosed embodiments provide a grounding assembly 5 in the electronic device. The switching part 51 of the grounding component 5 is arranged between the antenna component 3 and the audio component 4 in a penetrating way, so that the antenna component 3 and the audio component 4 can be at least partially isolated; the first grounding piece 52 and the second grounding piece 53 of the grounding component 5 are respectively and electrically connected with the switching part 51, the first grounding piece 52 is electrically connected with the screen steel plate 2, and the second grounding piece 53 is electrically connected with the metal back cover 1, so that the effect of grounding current can be realized, the coupling effect between the audio component 4 and the antenna component 3 can be effectively eliminated, and the performance degradation of the antenna component 3 is avoided. In addition, the first grounding member 52 and the second grounding member 53 are respectively located at two opposite sides of the audio component 4, so that the opening of the groove structure of the adapting portion 51 faces the audio component 4, and the partial structure of the audio component 4 is actually located in the groove structure of the adapting portion 51, so that the space occupied by the grounding component 5 is smaller, and excessive abdication of the audio component 4 and the antenna component 3 to the grounding component 5 is not required, so that the space utilization rate of the electronic device is higher.

In some embodiments, referring to fig. 1, 2 and 4, the first adaptor 511 is attached to the side of the audio component 4 near the screen steel plate 2, and the second adaptor 513 is attached to the side of the audio component 4 near the metal back cover 1;

Based on the above arrangement, the space required for the grounding element 5 can be further reduced, so that the electronic device can eliminate the coupling effect between the audio element 4 and the antenna element 3 without reserving too much space between the audio element 4 and the antenna element 3.

In some embodiments, the antenna assembly 3 is a resonant cavity antenna and the metal back cover 1 is a seamless metal back cover. Through setting up antenna assembly 3 for resonant cavity antenna for electronic equipment need not to additionally set up fracture or opening for antenna assembly 3, and metal back of body lid 1 can be for the no fracture formula back of body lid, is favorable to improving electronic equipment's pleasing to the eye degree. Alternatively, the antenna component 3 may be a resonant cavity wifi2.4G antenna, i.e. a resonant cavity antenna with a main operating frequency band of 2.4G.

In some embodiments, referring to fig. 3, the antenna assembly 3 has a feed point 31, and the ground assembly 5 is less than a first threshold distance from the feed point 31.

the intermediate adaptor 512 is disposed between the target audio component x and the antenna component 3, and the first adaptor 511 and the second adaptor 513 are respectively disposed on opposite sides of the target audio component x.

In the present embodiment, the antenna assembly 3 is located between two sub-audio assemblies, but the coupling strength between different sub-audio assemblies and the antenna assembly 3 may be different due to the difference in the positions of the feeding points 31 of the antenna assembly 3. By determining one of the first sub-audio component 42 and the second sub-audio component 43, which is smaller in distance from the feeding point 31, as the target audio component x, the intermediate adapter 512 is inserted between the target audio component x and the antenna component 3, so that the strong coupling effect existing in the electronic device can be eliminated in a targeted manner.
