The second earpiece 2032c is disposed above the second display screen, and the second microphone 2034c is disposed in the acoustic cavity of the second earpiece 2032 c. A third microphone 2035c is disposed on top of the mobile terminal 20 c. The voice codec 2021c is electrically connected to the detection unit 204c for receiving the detection signal, and is also electrically connected to the first microphone 2033c, the second microphone 2034c, and the third microphone 2035 c. The first electronic switch 2022c is electrically connected between the speech codec 2021c and the first earpiece 2031 c. The second electronic switch 2023c is electrically connected between the voice codec 2021c and the second receiver 2032 c.

When the detecting unit 204c detects that the first display screen is in the call state, the voice codec 2021c controls the first electronic switch 2022c to be turned on, the second electronic switch 2023c is turned off, the first earpiece 2031c is gated by the voice codec 2021c through the first electronic switch 2022c, and the third microphone 2035c is controlled to be the main microphone, the first microphone 2033c is used as the ANC microphone, and the second microphone 2034c collects the ambient noise, i.e., controls the voice call unit 203c to operate in the first on state.

When the detecting unit 204c detects that the second display screen is in the call state, the voice codec 2021c controls the first electronic switch 2022c to be turned off, the second electronic switch 2023c to be turned on, the voice codec 2021c gates the second receiver 2032c through the second electronic switch 2023c, and simultaneously controls the third microphone 2035c to be the main microphone, the second microphone 2034c to be the ANC microphone, and the first microphone 2033c collects the ambient noise, i.e., controls the voice call unit 203c to operate in the second state. In this embodiment, the detecting unit 204c detects the call states of the first display screen and the second display screen, and then the audio control unit 202c controls the first electronic switch 2022c and the second electronic switch 2023c to be turned on or off according to the call states of the first display screen and the second display screen, and selects to gate the first earpiece 2031c or the second earpiece 2032c, and simultaneously controls the first microphone 2033c, the second microphone 2034c and the third microphone 2035c to operate in different states, so that the audio call unit 203c operates in different states according to the call states of the display screens, thereby overcoming the defect that the mobile terminal 20c does not support the call of the two display screens, and improving user experience.

In other embodiments of the present invention, the voice codec 2021c is further configured to set the first state as a default state of the audio telephony unit 203c, and control the audio telephony unit 2023c to operate in the default state when the mobile terminal 20c is started. That is, when the mobile terminal 20c is started, the first electronic switch 2022c is in an on state by default, and the second electronic switch 2023c is in an off state by default, so as to gate the first earpiece, and at the same time, the third microphone 2035c is controlled to be the main microphone by default, the first microphone 2033c is used as the ANC microphone, and the second microphone 2034c collects the ambient noise. The voice codec 2021c is also used to restore the audio call unit 203c to the default state when the mobile terminal 20c ends the call. That is, if the first display screen is in the call state currently, the voice codec 2021c controls the voice call unit 203c to keep the current working state when the call is ended. If the second display screen is in the call state, when the call is finished, the voice codec 2021c controls the voice call unit 203c to return to the default state from the second state where the second display screen is currently located, that is, controls the first electronic switch 2022c to return to the on state from the off state, and controls the second electronic switch 2023c to return to the off state from the on state, so as to return the originally gated second earpiece to the gated first earpiece, and at the same time, the default control controls the third microphone 2035c to be the main microphone, the first microphone 2033c returns to be the ANC microphone from the originally collected environmental noise, and the second microphone 2034c returns to be the ANC microphone from the originally collected environmental noise for collecting the environmental noise.

Referring to fig. 6, fig. 6 is a block diagram of a mobile terminal 20c according to an embodiment of the invention.

In this embodiment, the voice codec 2021c includes EAR _ P pin, GPIOA pin, GPIOB pin, EAR _ N pin, M1 pin, M2 pin, and M3 pin. The first electronic switch 2022c is a MOS transistor Q1, and the second electronic switch 2023c is a MOS transistor Q2. The gate of the MOS transistor Q1 is electrically connected to the GPIOA pin of the speech codec 2021c, the source of the MOS transistor Q1 is electrically connected to the EAR _ P pin of the speech codec 2021c, the drain of the MOS transistor Q1 is electrically connected to one end of the first earpiece 2031c, and the other end of the first earpiece is electrically connected to the EAR _ N pin of the speech codec 2021 c. The gate of the MOS transistor Q2 is electrically connected to the GPIOB pin of the speech codec 2021c, the source of the MOS transistor Q2 is electrically connected to the source of the MOS transistor Q1, the drain of the MOS transistor Q2 is electrically connected to one end of the second earpiece 2032c, and the other end of the second earpiece 2032c is electrically connected to the other end of the first earpiece 2031 c. The first microphone 2033c is electrically connected to the M1 pin of the voice codec, the second microphone 2334c is electrically connected to the M2 pin of the voice codec 2021c, and the third microphone 2035c is electrically connected to the M3 pin of the voice codec 2021 c.

In this embodiment, after the mobile terminal 20c is activated, the GPIOA of the voice codec 2021c outputs a high level by default, i.e., the gate of the MOS transistor Q1 is high, so as to control the MOS transistor Q1 to be turned on, and the GPIOB of the voice codec 2021c outputs a low level by default, i.e., the gate of the MOS transistor Q2 is low, so as to control the MOS transistor Q2 to be turned off.

When the mobile terminal 20c receives the call request, the detecting unit 204c detects the call status of the first display screen and the second display screen. When the first display screen is bright and in a call state, the voice codec 2021c controls the voice call unit 203c to maintain a default state. That is, the GPIOA default output high level of the voice codec 2021c controls the MOS transistor Q1 to be turned on, and the GPIOB default output low level of the voice codec 2021c controls the MOS transistor Q2 to be turned off to gate the first earpiece 2031 c. Meanwhile, the voice codec 2021c sets the third microphone 2035c as the main microphone, the second microphone 2034c collects the ambient noise, and the first microphone 2033c as the ANC microphone.

When the second display screen is in the call state, the voice codec 2021c controls the voice call unit 203c to operate in the second state. That is, the gpio a of the voice codec 2021c outputs low to control the MOS transistor Q1 to turn off, and the gpio b of the voice codec 2021c outputs high to control the MOS transistor Q2 to turn on, so as to gate the second receiver 2032 c. Meanwhile, the voice codec 2021c sets the third microphone 2035c as the main microphone, the first microphone 2033c collects the ambient noise, and the second microphone 2034c as the ANC microphone. When the mobile terminal ends the call, the voice codec 2021c controls the voice call unit 203c to restore the default state.

In addition, the invention also provides a communication method.
