1. A program upgrade method, applied to a true wireless stereo (TWS) headphone, wherein the TWS headphone comprises a first wireless headphone and a second wireless headphone arranged in pairs, and the program upgrade method comprises:

establishing a wireless communication connection between the first wireless headphone and a terminal, and receiving, by the first wireless headphone, a first upgrade file sent by the terminal for upgrade; and

establishing a wireless communication connection between the second wireless headphone and the terminal, and receiving, by the second wireless headphone, a second upgrade file sent by the terminal for upgrade after the first wireless headphone completes upgrade.

2. The program upgrade method according to claim 1 , wherein the establishing a wireless communication connection between the first wireless headphone and a terminal comprises:

receiving, by the first wireless headphone, an upgrade instruction, generating an upgrade response information for entering an over-the-air (OTA) mode, and sending the upgrade response information to the terminal, for the terminal to receive the upgrade response information and establish a Bluetooth low energy (BLE) wireless communication connection with the first wireless headphone.

3. The program upgrade method according to claim 2 , wherein the receiving, by the first wireless headphone, an upgrade instruction and generating an upgrade response information for entering an OTA mode comprises:

performing, by a headphone charging box, a BLE broadcast in a case that the headphone charging box detects a preset event, wherein a broadcast field comprises a field for notifying the headphone to prepare to enter the OTA mode; and

executing an OTA code segment and performing a wireless communication scanning by the first wireless headphone, in a case that the headphone charging box detects that the first wireless headphone is placed at a first preset position, and generating, by the first wireless headphone, the upgrade response information for entering the OTA mode when an OTA signal is scanned by the first wireless headphone within a preset time period.

4. The program upgrade method according to claim 3 , further comprising:

disconnecting, by the first wireless headphone, the BLE wireless communication connection with the terminal, after the first wireless headphone completes upgrade; and

sending an upgrade completion instruction to the terminal, for the terminal to prompt an information display item indicating that an upgrade operation is completed and prompt an operation display information about disconnecting the BLE broadcast of the headphone charging box, after the second wireless headphone completes upgrade.

5. A true wireless stereo (TWS) headphone, comprising: an audio output, a communication interface, a memory and a processor, wherein the processor is configured to upgrade a program of the TWS headphone by applying the program upgrade method according to claim 1 .

6. A method for upgrading a program of a true wireless stereo (TWS) headphone, wherein the TWS headphone comprises a first wireless headphone and a second wireless headphone arranged in pairs, and the method comprises:

establishing a wireless communication connection between a terminal and the first wireless headphone, and sending a first upgrade file for upgrade to the first wireless headphone through the terminal; and

establishing a wireless communication connection between the terminal and the second wireless headphone, and sending a second upgrade file for upgrade to the second wireless headphone through the terminal after the first wireless headphone completes upgrade.

7. The method for upgrading a program of a TWS headphone according to claim 6 , wherein before the establishing a wireless communication connection between a terminal and the first wireless headphone, and sending a first upgrade file for upgrade to the first wireless headphone through the terminal, the method further comprises:

outputting an option for prompting whether to upgrade, when the terminal detects that a program version in a cloud has been updated; and

receiving an option instruction for performing a program upgrade, and prompting an operation instruction information for starting the program upgrade.

8. A system for upgrading a program of a true wireless stereo (TWS) headphone, comprising: a terminal and a TWS headphone, wherein the terminal is configured to:

establish a wireless communication connection with a first wireless headphone, and send a first upgrade file for upgrade to the first wireless headphone; and

establish a wireless communication connection with a second wireless headphone, and send a second upgrade file for upgrade to the second wireless headphone after the first wireless headphone completes upgrade.

9. The system for upgrading a program of a TWS headphone according to claim 8 , wherein the first wireless headphone is configured to: receive an upgrade instruction, generate an upgrade response information for entering an over-the-air (OTA) mode, and send the upgrade response information to the terminal; and

the terminal is configured to: receive the upgrade response information, and establish a Bluetooth low energy (BLE) wireless communication connection with the first wireless headphone.

10. The system for upgrading a program of a TWS headphone according to claim 9 , further comprising a headphone charging box, configured to perform a BLE broadcast in response to detecting a preset event, wherein a broadcast field comprises a field for notifying the headphone to prepare to enter the OTA mode; and

the first wireless headphone is configured to: execute an OTA code segment and perform a wireless communication scanning, in response to detecting that the first wireless headphone is placed at a first preset position of the headphone charging box; and generate the upgrade response information for entering the OTA mode when an OTA signal is scanned within a preset time period.

11. A computer-readable storage medium for storing a computer program, wherein the computer program, when executed by a processor, implements the program upgrade method according to claim 1 .

12. A true wireless stereo (TWS) headphone, comprising: an audio output, a communication interface, a memory and a processor, wherein the processor is configured to upgrade a program of the TWS headphone by applying the program upgrade method according to claim 2 .

13. A true wireless stereo (TWS) headphone, comprising: an audio output, a communication interface, a memory and a processor, wherein the processor is configured to upgrade a program of the TWS headphone by applying the program upgrade method according to claim 3 .

14. A true wireless stereo (TWS) headphone, comprising: an audio output, a communication interface, a memory and a processor, wherein the processor is configured to upgrade a program of the TWS headphone by applying the program upgrade method according to claim 4 .

15. A computer-readable storage medium for storing a computer program, wherein the computer program, when executed by a processor, implements the method for upgrading a program of a true wireless stereo (TWS) headphone according to claim 6 .
