Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

As described above, in order to reduce radiation of the antenna to a human body, the antenna of the current mobile phone is mostly disposed at the bottom of the mobile phone, and considering an audio effect, an audio output is also disposed at the bottom of the mobile phone, which often causes two functional modules to seize a space each other. Under this condition, in order to promote the space size in sound chamber, need extrude loudspeaker to the position of antenna as far as possible, but can influence the antenna performance, perhaps the thickness of attenuate support, but can influence the structural strength of whole support, perhaps expose partial loudspeaker to the support outside, production technology is complicated, and the installation is loaded down with trivial details, can increase cost. In addition, the integrity of the sound cavity support must be destroyed in order to contact and connect the antenna with the main board, and the space occupied by the antenna body also needs to sacrifice a part of audio performance. Specifically, please refer to fig. 1, where fig. 1 is a schematic distribution diagram of a bottom acoustic cavity and an antenna of a mobile phone according to an embodiment of the present application.

Referring to fig. 2, in the prior art, a plastic bracket 30 is mostly used, a connecting member 302 penetrates through the plastic bracket 30, and the antenna 40 is connected to the main board 20 through the connecting member 302. The horn cavity 301 is a sound cavity, the horn cavity 301 is disposed in the plastic bracket 30, and a part of the horn is exposed outside the bracket. The structure shown in fig. 2 has the disadvantages that the sound cavity space is small, the support is thin, the integrity of the sound cavity support is damaged, and a part of audio performance is sacrificed.

In order to overcome the above problem, the embodiment of the present application provides a sound cavity support. As shown in fig. 3, a sound cavity 101 is arranged in the sound cavity support 10, the sound cavity 101 is used for mounting a loudspeaker, a part of the sound cavity support 10 serves as an antenna unit, and the antenna unit is connected with the main board 20; the sound cavity holder 10 is a conductive holder.

It should be noted that the material of the sound cavity holder 10 in the embodiment of the present application is a conductive material.

With respect to fig. 2, the antenna 40 is connected to the motherboard 20 via the connector 302, and the connector 302 penetrates the plastic bracket 30, thereby destroying the integrity of the plastic bracket 30. In the scheme provided by the embodiment of the present application, a part of the sound cavity support 10 is directly used as an antenna unit, that is, a part of the support is used as an antenna radiator, and the sound cavity support 10 and the antenna unit are integrated together.

After a part of the sound cavity bracket 10 is used as an antenna unit, firstly, an extra reserved space is not needed, the antenna is installed, and the space originally used for installing the antenna can also be used as a part of the sound cavity bracket 10, so that the size of the space of the sound cavity bracket 10 can be increased. Further, the size of the sound cavity 101 disposed in the sound cavity holder 10 can be increased, and the audio effect can be improved. Secondly, the sound cavity support 10 can not be damaged by the antenna, the integrity of the sound cavity support is guaranteed, and audio performance loss is avoided.

In summary, the embodiment of the present application provides a sound cavity bracket, a sound cavity is arranged in the sound cavity bracket, the sound cavity is used for mounting a loudspeaker, a part of the sound cavity bracket is used as an antenna unit, and the antenna unit is connected with a main board; the sound cavity support is a conductive support. The antenna is installed without additionally reserving space, and the space originally used for installing the antenna can be used as a part of the sound cavity bracket, so that the size of the space of the sound cavity bracket can be increased. Furthermore, the size of the sound cavity arranged in the sound cavity support can be increased, and the audio effect is improved. Secondly, the sound cavity support can not be destroyed by the antenna, has ensured the integrality of sound cavity support, avoids audio performance loss.

On the basis of fig. 3, as to how to enable the antenna to meet more frequency requirements, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 4 and fig. 5. Fig. 4 is a schematic structural diagram of another sound cavity bracket provided in the embodiment of the present application, and fig. 5 is a comparison schematic diagram.

As shown in fig. 4, the sound cavity support 10 includes at least two partial supports 106, a non-conductive material filling band 104 is disposed between adjacent partial supports 106, and each of the adjacent partial supports 106 is provided with a connection contact 105, and the connection contacts 105 are used for realizing conduction with each other.

It can be understood that the first part support 106-1 is used as the antenna body, the second part support 106-2 is used as the grounding metal of the sound cavity support 10, and the connection relationship between the antenna body and the ground can be changed by adjusting the position and number of the connection contacts 105, so as to change the electrical length of the antenna body to meet more frequency requirements.

In a possible implementation manner, the second part support 106-2 may also be used as the body of the antenna, and the first part support 106-1 may be used as the grounding metal of the sound cavity support 10.

It should be noted that, the embodiments of the present application do not limit the components of the sound cavity holder 10, and the sound cavity holder 10 may be a complete metal with a gap in the middle and then filled with plastic. Or the antenna can be formed by combining a plurality of sections of supports to realize a plurality of frequencies or a plurality of antennas.

Compared with the plastic bracket 30 shown in fig. 5, the antenna is directly connected to the main board through the connecting piece 302, and the plastic bracket 30 is fixed to the main board through the screws 303, which makes it difficult to achieve the above-mentioned functional purpose.

In one possible implementation, the antenna unit is connected to the main board 20 through the contact spring 102.

In one possible implementation, the sound cavity support 10 is fixed to the main board 20 by conductive screws 103, and the antenna unit is connected to the main board 20 by the conductive screws 103.

Optionally, the sound cavity support 10 is directly locked to the main board 20 or the chassis through the conductive screws 103, so as to enhance the grounding strength. The antenna unit is connected with the main board 20 or the casing through the conductive screws 103, so that the number of contact spring pieces can be effectively reduced, and the structural strength of the whole machine is improved.

In one possible implementation, the sound cavity holder 10 is a metal holder.

It will be appreciated that a metal bracket of the same thickness is structurally stronger relative to a plastic bracket. Under the same structural strength requirement of satisfying, the thickness of metal support is less than the thickness of plastic support, can effectively reduce the thickness of support wall, increases the sound chamber volume.

And moreover, the sound cavity in the metal support is used for shielding electromagnetic interference of the outside to the loudspeaker, and the quality of audio is improved.

Meanwhile, the metal sound cavity can be directly grounded, so that electromagnetic interference of the outside to the loudspeaker can be shielded, and the metal sound cavity can also be used for shielding the electromagnetic interference of the loudspeaker to the antenna.

Optionally, the metal stent is an alloy stent.

The conductive screw 103 may be a grounding point of the antenna unit or an antenna feeding point of the antenna unit. By selecting different conductive screws 103 as the grounding points or antenna feeding points of the antenna unit, the characteristics (including shape structure and electrical length) of the antenna unit can be changed, so that more frequency requirements can be met.

Regarding the layout of a part of the sound cavity support 10 as an antenna unit, the embodiment of the present application also provides a possible way, please refer to fig. 6. Fig. 6 is a schematic layout diagram of a sound cavity support as an antenna unit according to an embodiment of the present application. As shown in fig. 6, the screw at the lower right corner is used as the antenna feeding point of the antenna unit, the second part of the bracket 106-2 is used as the body of the antenna, the first part of the bracket 106-1 is used as the grounding metal of the sound cavity bracket 10, and the second part of the bracket 106-2 is in contact with the ground (the first part of the bracket 106-1) through the connecting contact 105. In this case, the antenna element is equivalent to an inverted F-shaped antenna.

It can be understood that when different screws are selected as the feeding points of the antenna, different numbers of connecting contacts 105 are selected, and different grounding points are selected, the characteristics (including shape, structure, electrical length, etc.) of the antenna unit are changed, so as to meet more frequency requirements.

The embodiment of the application also provides terminal equipment, and the terminal equipment comprises the sound cavity support.
