Fig. 1 is a block diagram of an electronic device according to an embodiment of the present application. The electronic device 100 comprises a first antenna 101, a second antenna 102, a sensor 103 and a switch assembly 104; the first antenna 101 and the second antenna 102 are both connected with the sensor 103, the sensor 103 is connected with the switch assembly 104, and the first antenna 101 and the second antenna 102 are both connected with the switch assembly 104; the sensor 103 receives the electric signals output by the first antenna 101 and the second antenna 102, wherein the electric signals output by the first antenna 101 and the second antenna 102 are associated with a target position where a user touches the electronic device 100; the sensor 103 correspondingly outputs a decision signal to the switch assembly 104 based on the received electrical signal; the switching component 104 controls switching between the first antenna 101 and the second antenna 102 based on the decision signal.
In the embodiment of the application, the antenna is switched by sensing the contact position of the user and the electronic equipment through the sensor, so that the electronic equipment meets corresponding better communication requirements in different application scenes, the problem that the antenna is switched based on the signal strength of the antenna, and data is cut off due to the fact that the signal is repeatedly switched for a short time is avoided, and the experience of the user in using the electronic equipment is improved.
In some embodiments, the first antenna 101 is a top antenna and the second antenna 102 is a bottom antenna, i.e. the first antenna 101 is disposed at the top end of the electronic device and the second antenna 102 is disposed at the bottom end of the electronic device.
In other embodiments, the first antenna 101 is a bottom antenna, and the second antenna 102 is a top antenna, i.e. the first antenna 101 is disposed at the bottom end of the electronic device, and the second antenna 102 is disposed at the top end of the electronic device.
It should be noted that, in the embodiment of the present application, the first antenna 101 and the second antenna 102 may also be located at other positions of the electronic device. For example, the first antenna 101 is disposed at the left end of the electronic device, and the second antenna 102 is disposed at the right end of the electronic device; the first antenna 101 is disposed at the top end of the electronic device, the second antenna 102 is disposed at the right end of the frame of the electronic device, and the application is not limited in particular.

In some embodiments, the target location characterizes the first antenna 101 outputting a first capacitance signal that is less than or equal to a first capacitance threshold when the distance from the first antenna 101 to the user is greater than or equal to the first distance threshold;
When the target position represents that the distance between the second antenna 102 and the user is greater than or equal to the second distance threshold, the second antenna 102 outputs a second capacitance signal smaller than or equal to the second capacitance threshold.
Specifically, the target position is embodied as a near-far relationship of the user with the first antenna 101 and the second antenna 102. The first distance threshold is a distance between the first antenna 101 and the user when the user clings to an area corresponding to the first antenna 101 on the electronic equipment shell; when a user clings to an area corresponding to the first antenna 101 on the electronic device shell, the first antenna 101 outputs a first capacitance signal equal to a first capacitance threshold value, and the state of the first antenna at the moment is defined as 'approaching the user'. If the distance between the user and the first antenna 101 is greater than the first distance threshold, the first antenna 101 outputs a first capacitance signal smaller than the first capacitance threshold, and the state of the first antenna at this time is defined as "far from the user".
The second distance threshold is the distance between the second antenna 102 and the user when the user clings to the area corresponding to the second antenna 102 on the electronic equipment shell; when the user clings to the area corresponding to the second antenna 102 on the electronic device shell, the second antenna 102 outputs a second capacitance signal equal to a second capacitance threshold value, and the state of the second antenna at the moment is defined as 'approaching the user'. If the distance between the user and the second antenna 102 is greater than the second distance threshold, the second antenna 102 outputs a second capacitance signal smaller than the second capacitance threshold, and the state of the second antenna at this time is defined as "away from the user".
In some embodiments, if the first capacitance signal is equal to the first capacitance threshold and the second capacitance signal is equal to the second capacitance threshold, the sensor outputs a low level decision signal; if the first capacitance signal is equal to the first capacitance threshold value and the second capacitance signal is smaller than the second capacitance threshold value, the sensor outputs a high-level judgment signal; if the first capacitance signal is smaller than the first capacitance threshold value and the second capacitance signal is equal to the second capacitance threshold value, the sensor outputs a low-level judgment signal; if the first capacitance signal is smaller than the first capacitance threshold value and the second capacitance signal is smaller than the second capacitance threshold value, the sensor outputs a high-level judgment signal.
Specifically, when the states of the first antenna 101 and the second antenna 102 are simultaneously "close to the user", the first capacitance signal output by the first antenna 101 is equal to the first capacitance threshold, the second capacitance signal output by the second antenna 102 is equal to the second capacitance threshold, and the sensor defines that the holding gesture of the user is in the head-hand mode at this time according to the received first capacitance signal and second capacitance signal, and outputs a low-level decision signal;
when the state of the first antenna 101 is "close to the user", the first capacitance signal output by the first antenna 101 is equal to the first capacitance threshold, the state of the second antenna 102 is "far from the user", the second capacitance signal output by the second antenna 102 is smaller than the second capacitance threshold, the sensor defines that the holding gesture of the user is the head mode at the moment according to the received first capacitance signal and the second capacitance signal, and outputs a high-level judgment signal;
When the state of the first antenna 101 is far away from the user, the first capacitance signal output by the first antenna 101 is smaller than the first capacitance threshold, the state of the second antenna 102 is close to the user, the second capacitance signal output by the second antenna 102 is equal to the second capacitance threshold, and the sensor defines that the holding gesture of the user is a hand mode at the moment according to the received first capacitance signal and the second capacitance signal and outputs a low-level judgment signal;
when the state of the first antenna 101 is "far from the user", the first capacitance signal output by the first antenna 101 is smaller than the first capacitance threshold, the state of the second antenna 102 is "far from the user", the second capacitance signal output by the second antenna 102 is smaller than the second capacitance threshold, and the sensor defines that the holding gesture of the user is a space mode at this time according to the received first capacitance signal and the second capacitance signal, and outputs a high-level decision signal.
In some embodiments, different user gestures may correspond to different modes. For example, the electronic device is set as a mobile phone, the head mode means that the mobile phone is clamped between the head and the shoulder of the user, the space mode means that the mobile phone is far away from the user and placed on a certain plane, the hand mode means that the user holds the mobile phone to browse web pages and watch videos, and the like, the head-hand mode means that the user holds the mobile phone to place beside the ear for conversation or plays games on the lateral screen of the mobile phone, and at the moment, two hands hold two ends of the mobile phone.
