The embodiment of the application provides electronic equipment. The electronic device can be a smart phone, a tablet computer and the like. In some embodiments, referring to fig. 1 and 3, the electronic device 100 includes a display screen 10, a middle frame 20, a circuit board 30, a battery 40, and a rear cover 50.

Wherein the display screen 10 is mounted on the rear cover 50 to form a display surface of the electronic device 100. The display screen 10 serves as a front housing of the electronic device 100, and forms a receiving space with the rear cover 50 for receiving other electronic components or functional components of the electronic device 100. Meanwhile, the display screen 10 forms a display surface of the electronic apparatus 100 for displaying information such as images, texts, and the like. The Display screen 10 may be a Liquid Crystal Display (LCD) or an organic light-Emitting Diode (OLED) Display screen.

In some embodiments, a glass cover plate may be disposed over the display screen 10. Wherein, the glass cover plate can cover the display screen 10 to protect the display screen 10 and prevent the display screen 10 from being scratched or damaged by water.

In some embodiments, as shown in FIG. 1, the display screen 10 may include a display area 11 and a non-display area 12. The display area 11 performs a display function of the display screen 10 for displaying information such as images and texts. The non-display area 12 does not display information. The non-display area 12 can be used for setting functional components such as a camera, a receiver, a touch electrode of a display screen, and the like. In some embodiments, the non-display area 12 may include two areas located at the upper and lower portions of the display area 11.

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 comprises only the display area 11 and no 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 rear cover 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.

The circuit board 30 is mounted inside the receiving space. For example, the circuit board 30 may be mounted on the middle frame 20 and received in the receiving space together with the middle frame 20. The circuit board 30 may be a motherboard of the electronic device 100. The circuit board 30 is provided with a grounding point to realize grounding of the circuit board 30. One, two or more of the functional components such as the motor, the microphone, the speaker, the receiver, the earphone interface, the universal serial bus interface (USB interface), the camera, the distance sensor, the ambient light sensor, the gyroscope, and the processor may be integrated on the circuit board 30. Meanwhile, the display screen 10 may be electrically connected to the circuit board 30.

In some embodiments, display control circuitry is disposed on the circuit board 30. The display control circuit outputs an electrical signal to the display screen 10 to control the display screen 10 to display information.

The battery 40 is mounted inside the receiving space. For example, the battery 40 may be mounted on the middle frame 20 and be received in the receiving space together with the middle frame 20. The battery 40 may be electrically connected to the circuit board 30 to enable the battery 40 to power the electronic device 100. The circuit board 30 may be provided thereon with a power management circuit. The power management circuit is used to distribute the voltage provided by the battery 40 to the various electronic components in the electronic device 100.

The rear cover 50 is used to form an outer contour of the electronic device 100. The rear cover 50 may be integrally formed. In the forming process of the rear cover 50, a rear camera hole, a fingerprint identification module mounting hole and the like can be formed in the rear cover 50.

In some embodiments, the back cover 50 may be a metal back cover, such as a metal such as magnesium alloy, stainless steel, or the like. It should be noted that the material of the rear cover 50 in the embodiment of the present application is not limited thereto, and other manners may also be adopted, for example, the rear cover 50 may be a plastic rear cover, and for example, the rear cover 50 may be a ceramic rear cover. For another example, the rear cover 50 may include a plastic portion and a metal portion, and the rear cover 50 may be a rear cover 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 rear cover structure.

In some embodiments, referring to fig. 4, electronic device 100 also includes capacitive sensor 60. The capacitive sensor 60 is mounted within the rear cover 50. For example, the capacitive sensor 60 may be accommodated in an accommodating space formed by the display panel 10 and the rear cover 50. The capacitive sensor 60 is used to detect the proximity of an external conductor.

The external conductor may comprise a part of the user's body, such as the user's hand or head, among others. It can be appreciated that since the hands, head, etc. of the user's body are conductors, when these parts of the user's body are close to the electronic device 100, some performance of the electronic device 100 may be affected. For example, when a user holds the electronic device 100 with a hand, the hand may shield the antenna structure of the electronic device 100, thereby affecting the stability of the electronic device 100 for transmitting and receiving wireless signals.

The capacitance sensor 60 is provided in the electronic apparatus 100 so that the approach of the external conductor can be detected by the capacitance sensor 60. For example, during the use of the electronic device 100, the user's hand may be held on the electronic device 100, and the capacitive sensor 60 may be used to detect the holding position of the user. The electronic device 100 may then respond to reduce the impact of the external conductor on the performance of the electronic device 100.

In some embodiments, referring to fig. 5, the number of capacitive sensors 60 is at least two. For example, the number of capacitive sensors 60 may be two, three, or more. The at least two capacitive sensors 60 are spaced apart.

For example, as shown in fig. 5, when the number of the capacitive sensors 60 is two, two capacitive sensors 60 may be disposed at the top and bottom of the electronic device 100, respectively. For another example, when the number of the capacitive sensors 60 is three, one may be disposed on the top of the electronic device 100, and one may be disposed on each of the left and right sides of the bottom of the electronic device 100.

In some embodiments, an antenna structure may be formed on the middle frame 20. The antenna structure may be used for transmitting and/or receiving wireless signals. The circuit board 30 may be provided with electronic components such as a radio frequency module and a switch assembly. At this time, the antenna structure formed on the middle frame 20 and the electronic components provided on the circuit board 30 may constitute an antenna assembly.

In some embodiments, referring to fig. 6, fig. 6 illustrates a schematic diagram of the antenna assembly 70. The antenna assembly 70 includes a radio frequency module 71, a switch assembly 72, and at least three

antenna structures

73A, 73B, 73C. The rf module 71 is coupled to the three

antenna structures

73A, 73B, 73C through the switch assembly 72. In some embodiments, the three

antenna structures

73A, 73B, 73C may be antenna radiators.

It should be noted that any one of the three

antenna structures

73A, 73B, 73C may be used as the first antenna structure, any another one may be used as the second antenna structure, and the remaining one may be used as the third antenna structure. For example, antenna structure 73A may serve as a first antenna structure, antenna structure 73B may serve as a second antenna structure, and antenna structure 73C may serve as a third antenna structure. The first antenna structure, the second antenna structure and the third antenna structure are only used for distinguishing different antenna structures and are not used for limiting the specific positions of the antenna structures.

Wherein, the radio frequency module 71 can be disposed on the circuit board 30 of the electronic device 100. The rf module 71 includes a first port 711 and a second port 712. The first port 711 is used for transmitting and receiving signals, and the second port 712 is used for receiving signals.

For example, the first port 711 may be configured to transmit and receive at least one of a Low frequency Band (LB), a medium frequency Band (MB), and a High frequency Band (HB). The second port 712 may be used for receiving at least one of LB, MB, HB.

The at least three

antenna structures

73A, 73B, 73C are used for transmitting and/or receiving signals, respectively. Wherein each of the at least three

antenna structures

73A, 73B, 73C may independently perform transmitting and/or receiving signals.

It should be noted that the antennas in the electronic device 100 can be divided into a main set antenna and a diversity antenna. Wherein the main set of antennas are used for both transmitting and receiving signals and the diversity antennas are used for only receiving signals. The at least three

antenna structures

73A, 73B, 73C may be used as a main set antenna structure of the electronic device 100, or may be used as a diversity antenna structure of the electronic device 100. The actual function of the at least three

antenna structures

73A, 73B, 73C may be set as desired.

Wherein the three

antenna structures

73A, 73B, 73C have an initial state. In the initial state, the first antenna structure 73A is used as a main diversity antenna, and the second antenna structure 73B or the third antenna structure 73C is used as a diversity antenna.

The switch assembly 72 is configured to switch the second antenna structure 73B or the third antenna structure 73C to a main diversity antenna and the first antenna structure 73A to a diversity antenna according to the detected user holding position.

The switch assembly 72 is coupled to the first port 711, the second port 712 and the at least three

antenna structures

73A, 73B, 73C of the radio frequency module 71, respectively. The switch component 72 is configured to control the first port 711 of the rf module 71 to switch on one of the at least three

antenna structures

73A, 73B, 73C and control the second port 712 of the rf module 71 to switch on another of the at least three

antenna structures

73A, 73B, 73C according to the detected user holding position. For example, in some embodiments, the switch assembly 72 is configured to control the first port 711 of the rf module 71 to switch on the second antenna structure 73B or the third antenna structure 73C, and control the second port 712 of the rf module 71 to switch on the first antenna structure 73A according to the detected user holding position.

The above coupling merely indicates a physical connection state between the electronic components, and does not indicate that the electronic components coupled to each other are in an electrically connected state. The above-mentioned connection indicates an electrical connection state between the electronic components, and the electronic components connected to each other can transmit an electrical signal.

Since the first port 711 of the rf module 71 is used for transmitting and receiving signals, when the first port 711 switches on one of the

antenna structures

73A, 73B, 73C, for example, the antenna structure 73B is switched on, the switched-on antenna structure 73B performs transmission and reception of signals, that is, the switched-on antenna structure 73B serves as a main antenna structure of the electronic device 100.

Since the second port 712 of the rf module 71 is used for receiving signals, when the second port 712 is switched on another antenna structure of the

antenna structures

73A, 73B, 73C, for example, the antenna structure 73A is switched on, the switched-on another antenna structure 73A performs receiving of signals, that is, the switched-on antenna structure 73A serves as a diversity antenna structure of the electronic device 100.

In some embodiments, as shown in fig. 6, the switching assembly 72 includes a first input port 721, a second input port 722, a first output port 723, a second output port 724, and a third output port 725. The first input port 721 is coupled to the first port 711 of the rf module 71. The second input port 722 is coupled to the second port 712 of the rf module 71, and the first output port 723 is coupled to the first antenna structure 73A. The second output port 724 is coupled with the second antenna structure 73B. The third output port 725 is coupled to the third antenna structure 73C.

The first input port 721 may be connected to any one of the first output port 723, the second output port 724, and the third output port 725. The second input port 722 may be connected to any one of the first output port 723, the second output port 724, and the third output port 725.

In practical applications, when the first input port 721 connects one of the first output port 723, the second output port 724, and the third output port 725, the second input port 722 connects another one of the input ports.

For example, when the first input port 721 connects the first output port 723, the second input port 722 connects the second output port 724 or the third output port 725. Therefore, it is possible to avoid the situation where the first input port 721 and the second input port 722 are connected to the same output port.

In some embodiments, as shown in FIG. 7, the switch assembly 72 comprises a double-pole, multiple-throw switch. For example, the switch assembly 72 may be a double pole, triple throw switch. The first input port 721 and the second input port 722 are input terminals of the double-pole multi-throw switch, and the first output port 723, the second output port 724 and the third output port 725 are output terminals of the double-pole multi-throw switch. The first input port 721 and the second input port 722 may each be connected to any one of the first output port 723, the second output port 724, and the third output port 725.

In some embodiments, as shown in fig. 8, the switch assembly 72 includes a first single pole, multiple throw switch 72A and a second single pole, multiple throw switch 72B. For example, the first and second single-pole,

multi-throw switches

72A and 72B are each single-pole, three-throw switches. The first input port 721 and the second input port 722 are respectively an input terminal of the first single-pole multi-throw switch 72A and an input terminal of the second single-pole multi-throw switch 72B. The first, second and

third output ports

723, 724, 725 include the output of the first single-pole-multi-throw switch 72A and the output of the second single-pole-multi-throw switch 72B.

For example, each output of the first single-pole-multi-throw switch 72A may be connected to a respective output of the second single-pole-multi-throw switch 72B to form the first, second, and

third output ports

723, 724, 725, respectively.

In some embodiments, referring to fig. 9, antenna assembly 70 also includes a wireless fidelity module 74 and a fourth antenna structure 73D.

Wherein the wireless fidelity module 74 comprises a third port 741 and a fourth port 742. The third port 741 is configured to transmit and receive a Wireless Fidelity (WiFi) signal. The fourth port 742 is used for receiving wireless fidelity signals.

Wherein, the WiFi signals transmitted and received by the third port 741 include signals with frequencies of 2.4GHz and 5 GHz. The WiFi signals received by the fourth port 742 also include signals with frequencies of 2.4GHz and 5 GHz.

The fourth antenna structure 73D is used for transmitting and receiving wireless fidelity signals. The fourth antenna structure 73D is coupled to a third port 741 of the wireless fidelity module 74.

The switch assembly 72 is also coupled to a fourth port 742 of the wireless fidelity module 74. The switch component 72 is used to control the fourth port 742 of the wireless fidelity module 74 to connect the first antenna structure 73A, the second antenna structure 73B, or the third antenna structure 73C.

When the fourth port 742 of the wireless fidelity module 74 turns on one of the

antenna structures

73A, 73B, 73C, the turned-on antenna structure performs the WiFi signal receiving function of the electronic device 100. Thus, the fourth antenna structure 73D acts as a WiFi main set antenna for the electronic device 100, and the switched antenna structure of 73A, 73B, 73C acts as a WiFi diversity antenna for the electronic device 100.

In some embodiments, as shown in fig. 9, the switch assembly 72 further includes a third input port 726. The third input port 726 is coupled with the fourth port 742 of the wireless fidelity module 74. The third input port 726 may be connected to any one of the first output port 723, the second output port 724, and the third output port 725.

In some embodiments, referring to fig. 10, the antenna assembly 70 further includes a satellite positioning module 75 and a fourth antenna structure 73D.

Wherein the satellite positioning module 75 comprises a fifth port 751 and a sixth port 752. The fifth port 751 is used for transmitting and receiving satellite positioning signals, and the sixth port 752 is used for receiving satellite positioning signals.

The Satellite positioning signal transmitted and received by the fifth port 751 comprises at least one of a Global Positioning System (GPS) signal, a BeiDou Navigation Satellite System (BDS) signal, and a GLONASS Satellite Navigation System (GLONASS) signal. The satellite Positioning signal received by the sixth port 752 also includes at least one of a Global Positioning System (GPS) signal, a BeiDou navigation satellite System (BDS) signal, and a GLONASS satellite navigation System (GLONASS) signal.

The fourth antenna structure 73D is used for transmitting and receiving satellite positioning signals. The fourth antenna structure 73D is coupled to a fifth port 751 of the satellite positioning module 75.

The switch assembly 72 is also coupled to a sixth port 752 of the satellite positioning module 75. The switch assembly 72 is configured to control the sixth port 752 of the satellite positioning module 75 to connect to the first antenna structure 73A, the second antenna structure 73B, or the third antenna structure 73C.

When one of the

antenna structures

73A, 73B, 73C is switched on by the sixth port 752 of the satellite positioning module 75, the switched-on antenna structure performs a satellite positioning signal receiving function of the electronic device 100. Thus, the fourth antenna configuration 73D serves as a satellite positioning main set antenna of the electronic apparatus 100, and the antenna configuration switched on among the

antenna configurations

73A, 73B, 73C serves as a satellite positioning diversity antenna of the electronic apparatus 100.

It is noted that in some embodiments, antenna assembly 70 may include both a wireless fidelity module 74 and a satellite positioning module 75. At this time, the fourth antenna structure 73D is used for transmitting and receiving both the wireless fidelity signal and the satellite positioning signal.

In some embodiments, as shown in fig. 10, the switch assembly 72 further includes a fourth input port 727. The fourth input port 727 is coupled to the sixth port 752 of the satellite positioning module 75.

In some embodiments, a ground point 763 is provided on the antenna carrier 76, as shown in fig. 11. The ground point 763 may be connected to a ground point on the circuit board 30 of the electronic device 100 to enable grounding of the antenna carrier 76. The first antenna structure 73A, the second antenna structure 73B, and the third antenna structure 73C are connected to the ground point 763, respectively. Thereby, the grounding of the at least three

antenna structures

73A, 73B, 73C, respectively, may be achieved.

In some embodiments, as shown in fig. 11, the antenna carrier 76 includes a first end 761 and a second end 762 disposed opposite one another. For example, the first end 761 may be a top portion of the antenna carrier 76 and the second end 762 may be a bottom portion of the antenna carrier 76.

Two of the at least three

antenna structures

73A, 73B, 73C are disposed at a first end of the antenna carrier 76 and another one of the at least three

antenna structures

73A, 73B, 73C is disposed at a second end of the antenna carrier 76.

For example, the first and

second antenna structures

73A and 73B of the at least three antenna structures are disposed at the first end 761 of the antenna carrier 76. The third antenna structure 73C is disposed at the second end 762 of the antenna carrier 76.

In some embodiments, as shown in fig. 11, the first end portion 761 of the antenna carrier 76 includes a first side 761A and a second side 761B that are oppositely disposed. For example, the first side 761A may be a right side of the first end portion 761, and the second side 761B may be a left side of the first end portion 761. The first antenna structure 73A and the second antenna structure 73B are respectively disposed on the first side 761A and the second side 761B.

In some embodiments, as shown in fig. 11, the number of capacitive sensors 60 in electronic device 100 may be equal to the number of antenna structures included by antenna assembly 70, with each capacitive sensor 60 disposed at the location of one antenna structure.

For example, if the antenna assembly 70 includes three

antenna structures

73A, 73B, 73C, the number of capacitive sensors 60 may be three. Also, three capacitive sensors 60 are provided at the

antenna structures

73A, 73B, 73C, respectively. Thus, each capacitive sensor 60 can detect the presence or absence of an external conductor (e.g., user hand, head) proximity at the antenna structure at the location. For example, capacitive sensor 60 at antenna structure 73A may detect whether the user's grip position is located at antenna structure 73A, capacitive sensor 60 at antenna structure 73B may detect whether the user's grip position is located at antenna structure 73B, and capacitive sensor 60 at antenna structure 73C may detect whether the user's grip position is located at antenna structure 73C. Thus, the three capacitive sensors 60 can detect the holding position of the user on the electronic device 100.

Upon detecting the presence of an external conductor proximity at an antenna structure, electronic device 100 may control antenna assembly 70 to switch between performing a main set antenna function and performing a diversity antenna function in a plurality of antenna structures. For example, when the capacitive sensor 60 at the antenna structure 73B detects the approach of the external conductor, it indicates that the external conductor is close to the antenna structure 73B. At this time, the electronic device 100 may control the antenna assembly 70 to switch the main set antenna for transmitting and receiving radio frequency signals to the antenna structure 73C, and switch the diversity antenna for receiving radio frequency signals to the antenna structure 73A, so as to reduce or avoid the influence of the external conductor on the communication performance of the electronic device 100, thereby improving the communication stability of the electronic device 100.

It should be noted that the above is merely an example. In other embodiments of the present invention, the electronic device 100 may also control the antenna assembly 70 to switch the main set antenna to the

antenna structure

73A or 73B and the diversity antenna to the other antenna structure according to the detected actual situation.

In some embodiments, capacitive sensor 60 in electronic device 100 may be implemented by functional multiplexing of certain electronic components in electronic device 100. For example, the

antenna structures

73A, 73B, 73C of the antenna assembly 70 need to be connected by a Flexible Printed Circuit (FPC) when coupled to the switch assembly 72 and grounded. At each antenna structure, the FPC connected to the antenna structure may be used as one electrode of the capacitive sensor 60, and the adjacent outer conductor may be used as the other electrode of the capacitive sensor 60, the outer conductor being looped with the FPC of the antenna structure through the ground, thereby forming the capacitive sensor 60. When the distance between the external conductor and the antenna structure changes, the capacitance value of the formed capacitive sensor 60 changes accordingly. So that when the change in capacitance value of the capacitive sensor 60 reaches a preset value, it indicates that the approach of the external conductor is detected.

In some embodiments, when at least one of the plurality of capacitive sensors 60 detects the proximity of an external conductor, the electronic device 100 may control the antenna assembly 70 to reduce the transmit power of the antenna structure to reduce electromagnetic radiation to the user when the electronic device 100 transmits signals.

In some embodiments, the electronic device 100 may also include a processor. The processor may be disposed on a circuit board of the electronic device 100. The processor is coupled to the antenna assembly 70 and the capacitive sensor 60, respectively.

When the electronic device 100 includes a plurality of capacitive sensors 60, the processor is coupled to the antenna assembly 70 and the plurality of capacitive sensors 60, respectively.

The processor is configured to control the switch assembly 72 in the antenna assembly 70 to switch the second antenna structure 73B or the third antenna structure 73C to a main diversity antenna and to control the switch assembly 72 to switch the first antenna structure 73A to a diversity antenna according to the user holding position detected by the capacitive sensor 60.

The embodiment of the application also provides an antenna switching method. The antenna switching method is applied to the electronic device 100 according to any of the embodiments.

The electronic device 100 includes an antenna assembly 70 and a capacitive sensor 60, wherein the antenna assembly 70 includes a first antenna structure 73A, a second antenna structure 73B, a third antenna structure 73C, a radio frequency module 71, and a switch assembly 72. The antenna assembly 70 has an initial state. In the initial state, the first antenna structure 73A serves as a main diversity antenna, and the second antenna structure 73B or the third antenna structure 73C serves as a diversity antenna.

The antenna switching method comprises the following steps:

acquiring the holding position of the user detected by the capacitive sensor 60;

and controlling a switch assembly 72 in the antenna assembly 70 to switch the second antenna structure 73B or the third antenna structure 73C to a main set antenna according to the holding position, and controlling the switch assembly 72 to switch the first antenna structure 73A to a diversity antenna.

Specifically, in some embodiments, controlling the switch assembly 72 in the antenna assembly 70 to switch the second antenna structure 73B or the third antenna structure 73C to a main set antenna and controlling the switch assembly 72 to switch the first antenna structure 73A to a diversity antenna according to the holding position includes:

when the holding position is located at the position of the first antenna structure 73A, the switch component 72 in the antenna component 70 is controlled to switch the second antenna structure 73B or the third antenna structure 73C to be a main diversity antenna, and the switch component 72 is controlled to switch the first antenna structure 73A to be a diversity antenna.

Therefore, when the user holds the hand at the first antenna structure 73A, the electronic device 100 may switch the main antenna to the second antenna structure 73B or the third antenna structure 73C, so as to reduce the influence of the hand of the user on the main antenna to receive and transmit the radio frequency signal, thereby improving the signal stability of the electronic device 100.
