In some embodiments, the wearable electronic device further comprises a processor electrically connected to the circuit board. And the processor is also electrically connected with the first radiator, the second radiator, the third radiator and the fourth radiator.

When the wearable electronic device works normally, the processor preferentially controls the third radiator arranged on the main body part to radiate wireless signals, so that the communication function of the wearable electronic device is realized. Meanwhile, when the processor controls the third radiator to radiate the wireless signal, the signal intensity of the wireless signal radiated by the third radiator can be acquired. And controls the operating states of the first radiator and the second radiator according to the signal strength of the third radiator 133.

The processor may monitor the signal strength of the wireless signal radiated by the third radiator in various ways, for example, querying a modem (modem) for signal parameter information of a current terminal, where the parameter information includes a signal strength value of a radio frequency signal, and of course, the signal parameter information may also include information such as a network type, a frequency band, and a channel.

When the processor detects that the signal intensity of the wireless signal radiated by the third radiator is greater than or equal to a preset signal intensity threshold, the processor is configured to control the first radiator 131 and the second radiator to be in a sleep state according to the signal intensity. It can be understood that, when the signal strength of the wireless signal radiated by the third radiator is greater than or equal to the preset signal strength threshold, it indicates that the signal strength of the wireless signal radiated by the third radiator reaches the communication standard, and at this time, the communication quality of the wearable electronic device is good.

When the processor detects that the signal intensity of the wireless signal radiated by the third radiator is smaller than the preset signal intensity threshold value, the processor is used for determining a target radiator from the first radiator and the second radiator according to the signal intensity and controlling the target radiator to be in a working state. When the signal intensity of the wireless signal radiated by the third radiator is smaller than the preset signal intensity threshold value, it indicates that the signal intensity of the wireless signal radiated by the current third radiator does not reach the communication standard, and at this time, the communication quality of the wearable electronic device is poor. Therefore, at this time, it is necessary to control the first radiator or the second radiator to be in a working state, and the signal strength of the wireless signal received and transmitted by the wearable electronic device is enhanced through the wireless signal radiated by the first radiator or the second radiator, so as to improve the communication performance of the wearable electronic device.

Further, the preset signal strength threshold at least includes a first signal strength threshold and a second signal strength threshold, and the first signal strength threshold is greater than the second signal strength threshold.

When the processor detects that the signal intensity of the wireless signal radiated by the third radiator is greater than or equal to a first signal intensity threshold value, the processor is used for controlling the first radiator and the second radiator to be in a dormant state according to the signal intensity. It can be understood that, when the signal strength of the wireless signal radiated by the third radiator is greater than or equal to the first signal strength threshold, it indicates that the signal strength of the wireless signal radiated by the third radiator reaches the communication standard, and at this time, the communication quality of the wearable electronic device is good.

When the processor detects that the signal intensity of the wireless signal radiated by the third radiator is smaller than a first signal intensity threshold value, the processor is further configured to detect whether the signal intensity of the wireless signal is smaller than a second signal intensity threshold value.

And when the signal intensity of the wireless signal is greater than a second signal intensity threshold value, the processor is used for determining the first radiator as a target radiator according to the signal intensity and controlling the first radiator to be in a working state. The signal intensity of the whole wireless signal of the wearable electronic device is enhanced through the wireless signal radiated by the first radiation body, and the communication performance of the wearable electronic device is further improved.

When the signal strength of the wireless signal is smaller than the second signal strength threshold, the current wireless signal strength is weak, so that the processor is used for jointly determining the first radiator and the second radiator as the target radiator according to the signal strength and controlling the first radiator and the second radiator to be in a working state. The signal intensity of the whole wireless signal of the wearable electronic device is enhanced through the wireless signal radiated by the first radiation body and the second radiation head together, and the communication performance of the wearable electronic device is further improved.

Further, the processor needs to acquire the signal strength of the whole wireless signal of the wearable electronic device after controlling the first radiator and the second radiator to be in the working state. The processor is further configured to control the fourth radiator to be in an operating state when the signal strength of the wireless signal is less than the first signal threshold. The wireless signal radiated by the fourth radiator enhances the signal strength of the wireless signal of the wearable electronic device again, and then the communication performance of the wearable electronic device is improved.
