It is understood that the first control switch 203 may include four inputs 203a and four outputs 203 b.

In another embodiment, as shown in fig. 6, the first control switch 203 is a single-pole multi-throw switch, such as: single pole double throw switch. The number of the first control switches 203 may be two, and one first control switch 203 is electrically connected between the transmitting unit 202 and the first and

second radiators

10 and 11, that is, one end of one first control switch 203 is electrically connected to the transmitting unit 202, and the other end is electrically connected to the first radiator 10 and the second radiator 11; the other first control switch 203 is electrically coupled between the transmitting unit 202 and the third and

It is understood that the first control switch 203 may include two inputs 203c and four outputs 203 d.

In another embodiment, as shown in fig. 7, the first control switch 203 is a multi-pole multi-throw switch, such as: a double pole double throw switch, the number of the first control switches 203 may be one, and the first control switches 203 are electrically connected between the emission unit 202 and the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13. Specifically, the input portion 203e of the first control switch 203 is electrically connected to the transmitting unit 202, and the output portion 203f of the first control switch 203 is electrically connected to the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13, respectively. It is understood that the first control switch 203 may include one input 203e and four outputs 203 f.

The electrical coupling manner of the first control switch 203 and the transmitting unit 202 includes direct or indirect electrical connection, and also includes capacitive coupling or electromagnetic coupling. Optionally, the first control switch 203 is electrically coupled with the firing unit 202 through one of a conductive wire, a conductive pogo pin, an electrical connector, and the like. The first control switch 203 is electrically connected to each radiator in a direct or indirect electrical connection manner, and also includes capacitive coupling or electromagnetic coupling. Optionally, the first control switch 203 is capacitively coupled to each radiator.

The first control switch 203 is configured to switch among the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13, so that at least one radiator is used as a first target radiator and is electrically connected to the transmitting unit 202.

In one embodiment, as shown in fig. 8, the first control switch 203 switches among the first radiator 10, the second radiator 11, the third radiator 12 and the fourth radiator 13, so that one of the radiators is used as a first target radiator and is electrically connected to the transmitting unit 202. For example: when the first control switch 203 switches to the first radiator 10 and the transmitting unit 202 is turned on, that is, the first radiator 10 is the first target radiator, at this time, the first radiator 10 may transmit the second antenna signal. When the first control switch 203 switches to the second radiator 11 and the transmitting unit 202 is turned on, that is, the second radiator 11 is the first target radiator, at this time, the second radiator 11 may transmit the second antenna signal. Similarly, when the first control switch 203 switches to the third radiator 12 and the transmitting unit 202 is turned on, that is, the third radiator 12 is the first target radiator, the third radiator 12 may transmit the second antenna signal. When the first control switch 203 switches to connect the fourth radiator 13 with the transmitting unit 202, that is, the fourth radiator 13 is the first target radiator, the fourth radiator 13 can transmit the second antenna signal.

In another embodiment, as shown in fig. 9, the first control switch 203 switches among the first radiator 10, the second radiator 11, the third radiator 12 and the fourth radiator 13, so that two radiators are the first target radiator and are electrically connected to the transmitting unit 202. For example: when the first control switch 203 is switched to connect the first radiator 10 and the second radiator 11 with the transmitting unit 202, that is, the first radiator 10 and the second radiator 11 are both the first target radiators, both the first radiator 10 and the second radiator 11 can transmit the second antenna signal. When the first control switch 203 switches to the second radiator 11 and the third radiator 12 and the transmitting unit 202 is turned on, that is, the second radiator 11 and the third radiator 12 are both the first target radiators, and both the second radiator 11 and the third radiator 12 can transmit the second antenna signal. Similarly, the first control switch 203 can be switched to the first radiator 10, the third radiator 12 and the transmitting unit 202 to be conducted; or, the first radiator 10 and the fourth radiator 13 are switched to be conducted with the transmitting unit 202, or the second radiator 11 and the fourth radiator 13 are switched to be conducted with the transmitting unit 202, or the third radiator 12 and the fourth radiator 13 are switched to be conducted with the transmitting unit 202.

Of course, in other embodiments, the first control switch 203 may be used to switch among the first radiator 10, the second radiator 11, the third radiator 12 and the fourth radiator 13, so that the three radiators are the first target radiator and are conducted with the transmitting unit 202.

In one application scenario, when one of the four radiators is blocked, for example: a user holds the electronic device 100 with one hand, so that the first radiator 10 is shielded, and at this time, the first control switch 203 can be switched to at least one of the second radiator 11, the third radiator 12 and the fourth radiator 13 to serve as a first target radiator, and the first radiator is conducted with the transmitting unit 202 to transmit a signal, thereby reducing the influence on the communication performance of the electronic device 100 due to shielding and improving the capability of the electronic device 100 to transmit a signal.

In another application scenario, when two of the four radiators are shielded, for example: the user holds the electronic device 100 with both hands, so that the first radiator 10 and the third radiator 12 are shielded, and at this time, the user can switch to at least one of the second radiator 11 and the fourth radiator 13 as a first target radiator through the first control switch 203 and conduct with the transmitting unit 202 to transmit a signal, thereby reducing the influence on the communication performance of the electronic device 100 due to shielding and improving the capability of the electronic device 100 to transmit a signal.

The conductive middle frame 1 of the electronic device 100 provided by the present application includes a first radiator 10, a second radiator 11, a third radiator 12, and a fourth radiator 13 arranged in a ring shape at intervals, all four radiators being electrically connected to the receiving unit 201, so that when a user blocks (for example, blocks due to being held by one hand or two hands) none, one, two, or three of the four radiators, the electronic device 100 still has another one or more radiators capable of receiving antenna signals, so that the electronic device 100 has better receiving performance, and the first control switch 203 of the electronic device 100 can switch the first target radiator among the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13, so that one or more radiators which are less blocked by the user among the four radiators can be selected as the first target radiator in an application scenario, the second antenna signal is transmitted, thereby enabling the electronic device 100 to have better transmission performance.

Further, as shown in fig. 10, the electronic apparatus 100 further includes a controller 3. The controller 3 is electrically coupled with the first control switch 203. The electrical coupling manner of the controller 3 and the first control switch 203 includes direct or indirect electrical connection, and also includes capacitive coupling or electromagnetic coupling. Alternatively, the controller 3 and the first control switch 203 are electrically connected by one of a conductive wire, a conductive pogo pin, an electrical connector, and the like. The controller 3 is configured to control the first control switch 203 according to a foreground running application of the electronic device 100. Specifically, the controller 3 obtains the foreground running application, and controls the state of the first control switch 203 according to the obtained foreground running application, so that the first control switch 203 is switched to the corresponding radiator to be conducted with the transmitting unit 202. For example, when the controller 3 obtains that the foreground running application is a phone, the state of the first control switch 203 is controlled to conduct the first radiator 10 and the transmitting unit 202, wherein the first radiator 10 is shielded less or not shielded when the user answers the phone. When the controller 3 obtains the foreground running application as the target game (for example, a game requiring two-hand operation), the state of the first control switch 203 is controlled to make the second radiator 11 and/or the fourth radiator 13 conduct with the transmitting unit 202, wherein the second radiator 11 and the fourth radiator 13 are shielded less or not shielded when the user plays the target game.

As shown in fig. 11, the first control switch 203 may include a first sub-switch 230 and a second sub-switch 231.

The first sub-switch 230 may be one of a single-pole single-throw switch, a single-pole multi-throw switch, a multi-pole multi-throw switch, and the like. The first sub-switch 230 is electrically coupled between the transmission unit 202 and the first radiator 10. Alternatively, the input portion of the first sub-switch 230 is electrically connected to the first radiator 10, and the output portion of the first sub-switch 230 is electrically connected to the transmitting unit 202; alternatively, the input portion of the first sub-switch 230 is electrically connected to the transmitting unit 202, and the output portion of the first sub-switch 230 is electrically connected to the first radiator 10. The first sub-switch 230 is used to conduct the first radiator 10 and the transmitting unit 202 under the control of the controller 3. In other words, the controller 3 may realize the connection and disconnection between the first radiator 10 and the transmitting unit 202 by controlling the first sub-switch 230.

The second sub-switch 231 may be one of a single-pole-three-throw switch, a double-pole-three-throw switch, a three-pole-three-throw switch, a single-pole-four-throw switch, and the like. The second sub-switch 231 is electrically connected between the emission unit 202 and the second, third and

fourth radiators

11, 12 and 13, that is, one end of the second sub-switch 231 is electrically connected to the emission unit 202, and the other end of the second sub-switch 231 is electrically connected to the second, third and

fourth radiators

11, 12 and 13. Specifically, an input portion of the second sub-switch 231 is electrically connected to the transmitting unit 202, and an output portion of the second sub-switch 231 is electrically connected to the second radiator 11, the third radiator 12, and the fourth radiator 13, respectively. It is understood that the second sub-switch 231 has at least three outputs. The second sub-switch 231 is used for conducting the transmitting unit 202 with at least one of the second radiator 11, the third radiator 12 and the fourth radiator 13 under the control of the controller 3. In other words, the controller 3 may respectively connect and disconnect the second radiator 11, the third radiator 12, and the fourth radiator 13 to and from the transmitting unit 202 by controlling the second sub-switch 231.

In this embodiment, the connection and disconnection between the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13 and the transmitting unit 202 are respectively realized through two control switches, namely, the first sub-switch 230 and the second sub-switch 231, the number of the control switches is small, and the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13 are controlled by different sub-switches, wherein the first radiator 10 is controlled by the independent first sub-switch 230, which is beneficial to reducing the switching times of the first sub-switch 230 and the second sub-switch 231 when the first radiator 10 is used as a main radiator, and simplifies the control program of the controller 3 on the first sub-switch 230 and the second sub-switch 231.

In one embodiment, as shown in fig. 12, the first sub-switch 230 is one of a single-pole double-throw switch and a double-pole double-throw switch, that is, the first sub-switch 230 includes at least two output units, and the single-pole double-throw switch is taken as an example in this embodiment. Specifically, the first sub-switch 230 includes a first input part 230a, a first output part 230b, and a second output part 230 c. One end of the first input portion 230a is electrically coupled to the transmission unit 202. The other end of the first input portion 230a is used to electrically couple one end of the first output portion 230b or one end of the second output portion 230c under the control of the controller 3. In other words, the first input portion 230a can be switched to be conductive with the first output portion 230 b; alternatively, the first input portion 230a may be switched to be conductive with the second output portion 230 c. The other end of the first output portion 230b is electrically coupled to the first radiator 10. The other end of the second output portion 230c is electrically coupled to the second sub-switch 231.

The present embodiment can achieve the connection and disconnection between the first radiator 10 and the emission unit 202 by controlling the first sub-switch 230, and at the same time, since the second output portion 230c of the first sub-switch 230 is electrically connected to the second sub-switch 231, the electrical connection state between the second radiator 11, the third radiator 12, and the fourth radiator 13 and the emission unit 202 can be controlled by controlling the first sub-switch 230.

For example, when the first radiator 10 is connected to the transmitting unit 202, that is, the first input part 230a of the first sub-switch 230 is connected to the first output part 230b, and the first input part 230a is disconnected from the second output part 230c, no matter what state the second sub-switch 231 is in, the second radiator 11, the third radiator 12 and the fourth radiator 13 are all disconnected from the transmitting unit 202, so that when the first radiator 10 is required to be used as a main first target radiator, or when the first radiator 10 is required to be switched to be used as a first target radiator, the switching times of the first sub-switch 230 and the second sub-switch 231 are reduced, and the control procedures of the first sub-switch 230 and the second sub-switch 231 are simplified.

In addition, when any one or more of the second radiator 11, the third radiator 12 and the fourth radiator 13 is/are connected to the transmitting unit 202, that is, the first input part 230a and the second output part 230c are connected, and the first input part 230a and the first output part 230b of the first sub-switch 230 are disconnected, the connection or disconnection between any one or more of the second radiator 11, the third radiator 12 and the fourth radiator 13 and the transmitting unit 202 can be realized by controlling the second sub-switch 231. Of course, the common state of the second sub-switch 231 may also be set, so as to reduce the number of times of switching between the first sub-switch 230 and the second sub-switch 231 when any one or more of the second radiator 11, the third radiator 12, and the fourth radiator 13 is required to be switched to serve as the first target radiator through the cooperation of the first sub-switch 230 and the second sub-switch 231, and simplify the control program of the first sub-switch 230 and the second sub-switch 231.

When the second control switch 204 is the first control switch 203 in the above embodiment, it is different from the above embodiment in that the first control switch 203 (the second control switch 204) is used for switching among the first radiator 10, the second radiator 11, the third radiator 12 and the fourth radiator 13 when in the first operating state, so that at least one radiator is used as a first target radiator and is conducted with the transmitting unit 202, and the first target radiator is used for transmitting the second antenna signal; when the first control switch 203 (the second control switch 204) is in the second operating state, the first control switch is configured to select one or two radiators in turn among the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13, so that the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13 are alternately used as a second target radiator to be conducted with the transmitting unit 202, and the second target radiator is configured to transmit a third antenna signal under excitation of the transmitting unit 202. The first operating state and the second operating state are operating states of the first control switch 203 at different times.

When the second control switch 204 is independent of the first control switch 203 in the above embodiment, the structure of the second control switch 204 is the same as that of the first control switch 203 described above. At this time, if the first control switch 203 is in the working state, at least one of the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13 is conducted with the transmitting unit 202 as a first target radiator, and transmits a second antenna signal; if the second control switch 204 is in the working state, one or two radiators among the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13 are alternately conducted with the transmitting unit 202 as a second target radiator, and transmit a third antenna signal.

In this embodiment, by setting the second control switch 204, the electronic device 100 can transmit SRS signals on four radiators in turn, and one antenna is selected at a time to transmit, that is, the function of 1T4R is realized; or, the electronic device 100 transmits SRS signals by turns on four radiators, and selects two antennas to transmit at a time, that is, the 2T4R function, so that the information obtained by the base station is more comprehensive, more accurate data transmission is performed, and the efficiency of receiving the first antenna signal by the first radiator 10, the second radiator 11, the third radiator 12, and the fourth radiator 13 is improved.
