With the rapid development of scientific technology and the continuous improvement of living standards of people, in recent years, with the market competition of smart phones, considering that the cost of a 3.5mm audio interface on the smart phone is high, and the 3.5mm audio interface occupies more space in the smart phone, in order to improve the competitiveness of products at home, all large mobile phone manufacturers begin to avoid providing the 3.5mm audio interface for the smart phone, but replace the 3.5mm audio interface with a USB interface, when the smart phone plays audio information or collects audio information, one end of an earphone serving as a USB (Universal Serial Bus) device is connected with the USB interface of the smart phone, and the audio information is output or collected through the USB interface.

The switch module 202 is configured to control the first end 2021 of the switch module 202 to be conducted with the third end 2023 of the switch module 202, and control the second end 2022 of the switch module 202 to be conducted with the fourth end 2024 of the switch module 202 when it is determined that the USB Type-C male connector of the earphone is not inserted into the USB Type-C female connector 201.

The switch module 202 is further configured to control the first end 2021 of the switch module 202 and the second end 2022 of the switch module 202 to be conducted with the I2C bus and the I2S bus when it is determined that the USB Type-C male plug of the earphone is inserted into the USB Type-C female socket 201, so that the AP module 204 transmits audio data to the first end 2021 of the switch module 202 and the second end 2022 of the switch module 202 through the I2C bus and the I2S bus.

Exemplarily, the commutation module can determine that the USB Type-C male plug of the earphone is inserted into the USB Type-C female socket when the seventh end of the commutation module and the eighth end of the commutation module are grounded simultaneously.

In the technical scheme provided by the embodiment of the disclosure, by setting the switch module, when it is determined that the USB Type-C male head of the earphone is not inserted into the USB Type-C female seat, the first end of the switch module is controlled to be conducted with the third end of the switch module, and the second end of the switch module is controlled to be conducted with the fourth end of the switch module, so that when the USB Type-C male head of the earphone is not inserted into the USB Type-C female seat, the com1 end of the USB Type-C female seat is conducted with the DP end of the PMIC module, the com2 end of the USB Type-C female seat is conducted with the DM end of the PMIC module, and data can be transmitted from the com1 end/com 2 end of the USB Type-C male head to the DP end/DM end of the PMIC module when the USB Type-C male head of the earphone is not inserted into the USB Type-C female seat; and when the USB Type-C male connector of the earphone is inserted into the USB Type-C female connector, the first end of the switching module and the second end of the switching module are controlled to be communicated with the I2C bus and the I2S bus, so that the AP module transmits audio data to the first end of the switching module and the second end of the switching module through the I2C bus and the I2S bus, and the earphone can normally play audio.
