Or FM broadcast voice signals, One of the audio channels of the earphone 2 outputs a voice signal of the incoming call, and the other audio channel outputs a voice signal of the audio file 120 or FM broadcast.

Specifically, in step S04, the call control system 10 can send the first control instruction to the first audio output unit 14 and the second audio output unit 15 through the processor 11 to control the first audio output unit 14. And one input connected to the second audio output unit 15 and the audio processing unit 13 is in an off state, and the other input connected to the processor 11 is in an on state to receive an incoming call voice signal output by the processor 11. For example, the first control command can be a low level enable signal (Enable_A = 0).

In step S05, the call control system 10 can also send the second control command to the first audio output unit 14 or the second audio output unit 15 through the processor 11 to control the first audio output unit 14 and the first One of the two inputs of one audio output unit of the two audio output units 15 is connected to the audio processing unit 13 in an off state, and the other input connected to the processor 11 is in an on state to receive the processor. 11 incoming call voice signals. The other audio output unit maintains a conductive state with the audio processing unit 13 and continues to receive the voice signal of the audio file 120 or FM broadcast. For example, the second control command may also be a low level enable signal (Enable_B=0).

Further, after the step S04, when the call ends, the call control system 10 sends a third control command to the first audio output unit 14 and the second audio output unit 15, and controls the first audio output unit 14 and the second. The audio output unit 15 continues to receive the audio file of the audio file 120 or the FM broadcast output by the audio processing unit 13, and outputs the received voice signal to the earphone 2.

Accordingly, after the step S05, when the call ends, the call control system 10 Sending a fourth control command to the audio output unit that receives the incoming call, controlling the audio output unit to continue receiving the audio file of the audio file 120 or the FM broadcast output by the audio processing unit 13, and outputting the received voice signal to the earphone 2. For example, if the audio output unit that receives the incoming voice signal is the first audio output unit 14, the call control system 10 transmits the fourth control command to the first audio output unit 14. If the audio output unit that receives the incoming voice signal is the second audio output unit 15, the call control system 10 transmits the fourth control command to the second audio output unit 15.

In other embodiments, when the communication device 1 is in a call state, the user can also select to play the audio file 120 or listen to the FM broadcast as needed, so that the user can play the audio file 120 or listen to the FM broadcast while the communication device 1 is talking.
