In one embodiment, please refer to fig. 2, which provides a schematic diagram of a mobile terminal with an antenna resonance state adjustment function in another embodiment. The mobile terminal includes: detection component 101, processor 102, and resonant state switch 103.
The detection assembly 101 includes a detection sensor 101a and an auxiliary sensing element 101b, the detection assembly 101 is connected to the processor 102, the detection sensor 101a is electrically connected to the auxiliary sensing element 101b, and the detection sensor 101a is configured to detect a capacitance value of the auxiliary sensing element 101b, obtain a communication state of the mobile terminal, and send the communication state to the processor 102.
In a specific implementation, when the auxiliary sensing element 101b is in different connection states, the capacitance value may be different, and the detection sensor 101a is configured to detect the capacitance value of the auxiliary sensing element 101b, so as to obtain the connection state of the mobile terminal. For example, when the terminal is located on the left side of the head of the user and is in the direction of the left ear, and is held by the left hand, the capacitance of the auxiliary sensing element 101b is within a range greater than or equal to 19000 units and less than or equal to 22000 units, for example, the capacitance of the auxiliary sensing element 101b is 20000 units; when the terminal is positioned on the right side of the user's head and is in the direction of the right ear, and is held by the right hand, the capacitance of the auxiliary sensing element 101b is within a range larger than 22000 units, such as 32767 units. The detection sensor 101a can thus detect the capacitance value of the auxiliary inductive element 101b to obtain a different communication state and send this communication state to the processor 102. It should be noted that, for the above capacitance values, corresponding different unit values are preset, for example, 1pf is preset to 10000 unit values, and this example is only for illustrative purposes and is not meant to be a limitation of the present application. It should be noted that a detection chip, such as an SX9235 chip, may be used in the detection sensor 101 a.
In addition, in one embodiment, the detection sensor 101a is further provided with a detection signal line, the detection signal line is connected to the auxiliary sensing element 101b through a coaxial line, and the detection signal line detects the capacitance value of the auxiliary sensing element 101 b. Further, the detection sensor 101a is provided with a main detection signal line and a standby detection signal line, and the auxiliary sensing element 101b may be connected to the standby detection signal line through a coaxial line, and the detection sensor 101a detects a capacitance value of the auxiliary sensing element 101b through the standby detection signal line to obtain a communication state of the mobile terminal. The main induction line can be used for detecting the general state of the mobile terminal in the free space, so that the detection sensor sends the general state to the processor, namely the general state is the state of other uses, such as the state of using network data. In this embodiment, the spare signal line of the detection sensor 101a is directly connected to the auxiliary sensing element 101b, that is, the spare signal line that is not used by the detection sensor 101a can be used, so that the structure is simple, and the cost can be saved.

In this embodiment, the detection component 101 in the mobile terminal employs the detection sensor 101a and the auxiliary sensing element 101b, and the detection sensor 101a detects the capacitance value of the auxiliary sensing element 101b to obtain a connected state, so that the cost can be saved.
In one embodiment, the mobile terminal having the antenna resonance state adjustment function may further include: an offset state sensor. And the offset state sensor is connected with the processor, and may be in communication connection with the processor, and the offset state sensor is configured to detect an offset state sensing value of the mobile terminal and send the offset state sensing value to the processor. The processor is used for receiving the offset state induction value sent by the offset state inductor and judging the offset state of the mobile terminal according to the offset state induction value.
Further, the processor may be configured to use the offset state as a supplementary determination condition for generating the switching instruction, that is, to generate the switching instruction according to the offset state and the connection state of the terminal, and send the switching instruction to the resonance state switch. The processor is configured to generate a switching instruction and send the switching instruction to the resonant state switch when the offset state and the connected state both indicate that the mobile terminal is in the same state when the offset state is used as a supplementary determination condition for generating the switching instruction; when the offset state or the connected state indicates that the mobile terminals are not in the same state, the switching instruction is not generated. For example, when the offset state and the connected state both indicate that the mobile terminal is in the same direction of the head of the user, and the mobile terminal is held in the same direction of the head, and a call is made, a switching instruction is generated and sent to the resonance state switch. When the offset state and the connected state indicate that the mobile terminal is in an opposite state, the handover command is not generated.
For example, the mobile terminal further includes an offset state sensor, which is in communication connection with the processor, and the offset state sensor may detect an offset state sensing value, may be provided with an offset state sensing coordinate, and use the detected offset state sensing coordinate as the offset state sensing value, and send the offset state sensing value to the processor. The offset state sensor may be an acceleration sensor, a gravity sensor, a gyro sensor, or the like.
In this embodiment, the mobile terminal further includes an offset state sensor, and the offset state sensor may be in communication connection with the processor, so that misjudgment of occurrence of a connected state, which is detected only by the included detection component, may be avoided.
In one embodiment, the mobile terminal may further include a distance sensor, and the distance sensor is connected to the processor, and may be in communication with the processor. And the distance sensor is used for detecting the communication distance value of the mobile terminal and sending the communication distance value to the processor. Wherein, the communication distance value can be the distance value between the user and the mobile terminal.
Further, the processor is configured to receive the communication distance value sent by the distance sensor, and the processor is further configured to determine a relative distance between the mobile terminal and the user according to the communication distance value, where the relative distance is the communication distance. That is, the processor may be configured to determine a relative distance between the mobile terminal and the user according to the communication distance, so as to determine whether the mobile terminal is in a call state.
Further, the processor may be further configured to use the communication distance as a supplementary determination condition for generating the switching instruction, that is, to generate the switching instruction according to the communication distance and the connection state of the terminal, and send the switching instruction to the resonance state switch. The processor is configured to generate a switching instruction and send the switching instruction to the resonance state switch when the communication distance or the connection state indicates that the mobile terminals are in the same state when the communication distance is used as a supplementary determination condition for generating the switching instruction; when the communication distance or the connected state indicates that the mobile terminals are not in the same state, the switching instruction is not generated. For example, when the connected state indicates a call connection state when the mobile terminal is held by a hand in a direction corresponding to a direction of the head of the user in a direction different from the direction of the head, and the communication distance indicates that the mobile terminal is in a call state, a switching instruction is generated and transmitted to the resonance state switch assuming that the connected state and the call state are the same state indicating that the mobile terminal is in the same state. When the connected state indicates that the mobile terminal is in a direction different from the head of the user, and the communication distance indicates that the mobile terminal is not in the call state, the switching instruction is not generated. It should be noted that the distance sensor may be a distance sensor or the like.
The processor may be configured to generate the switching instruction using the communication distance, the connected state, and the offset state as the determination conditions. When the communication distance, the offset state and the connection state are used as the judgment conditions, the processor generates a switching instruction and sends the switching instruction to the resonance state switch when the communication distance, the offset state and the connection state indicate that the mobile terminals are in the same state; when the communication distance, the offset state, and the communication state indicate that the mobile terminals are not in the same state, the handover command is not generated. For example, when the offset state and the connected state both indicate that the mobile terminal is in the same direction of the head of the user, and the mobile terminal is held by a hand in a direction corresponding to the direction of the head to perform a call, and the communication distance indicates that the terminal is in the call state, a switching instruction is generated and sent to the resonance state switch. When the offset state and the connected state indicate that the mobile terminal is in an opposite state, the handover command is not generated. When the communication distance, the offset state, and the communication state indicate that the mobile terminals are not in the same state, the handover command is not generated.
In this embodiment, the mobile terminal further includes a distance sensor, and the gravity sensor may be in communication connection with the processor, so that it is possible to avoid erroneous determination caused by detection only by the detection component.
In one embodiment, the resonant state switch is a radio frequency switch with multi-resonant state switching functionality. The radio frequency switch is a circuit structure consisting of different switches and circuit elements, so that the radio frequency switch can adjust the capacitance value and the inductance value of the radio frequency circuit by adjusting the on-off state of the switch, thereby adjusting the resonant frequency of the antenna and adjusting the resonant state. The switches included in the rf switch may be single-pole double-throw switches, etc. The radio frequency switch chip used for the resonant state switch is QM13119, and may also be RF1694, etc.
