The sound source processor 108 transmits the sound source signal AS1 to an external speaker (not shown) through the switching device 104 and the sound source socket 102, so that the speaker plays the sound.

The resistor R1 has a first end coupled to a voltage source VDD, and a second end coupled between the switching device 104 and the switching device SW1 for When the switching device SW1 decouples the control terminal of the switching device 104 from the processor 106, the first level is provided by the voltage source VDD as the control signal CS2. It is worth noting that the first level provided by the voltage source VDD is the same as the first level of the control signal CS2. For example, in one embodiment of the invention, the first level is a high level, such as 3.3 volts, although the invention is not limited thereto.

When the sound source socket 102 is coupled to the four-ring sound source plug, the microphone pin MP is in contact with the four-ring sound source plug. Therefore, the microphone pin MP generates the control signal CS1 and supplies the control signal CS1 to the switching device SW1. When the switching device SW1 receives the control signal CS1, the switching device SW1 decouples the control terminal of the switching device 104 from the processor 106. It should be noted that when the control end of the switching device 104 is decoupled from the processor 106, the control signal CS2 is at the first level.

In the audio output mode, the switching device 104 receives the sound source signal AS1 from the sound source processor 108, and transmits the sound source signal AS1 to the left ear pin LP and the right ear pin RP of the sound source socket 102, and the left ear connector of the sound source socket 102 The foot LP and the right ear pin RP transmit the sound source signal AS1 to the four-loop sound source plug. Therefore, it can be ensured that when the four-loop audio source plug is inserted into the sound source socket 102, the mobile device 100 must be in the sound source output mode. In addition, when the sound source socket 102 is coupled to the three-ring sound source plug, the microphone pin MP is not in contact with the three-ring sound source plug. Therefore, the microphone pin MP does not generate control Signal CS1. When the switching device SW1 does not receive the control signal CS1, the switching device SW1 couples the control terminal of the switching device 104 to the processor 106. It should be noted that when the control terminal of the switching device 104 is coupled to the processor 106, the processor 106 provides the control signal CS3 as the control signal CS2. In other words, the mobile device 100 is in the sound source output mode or the software update mode depending on the control signal. For example, when the control signal CS2 is at the first level, the mobile device 100 is in the sound source output mode. In the audio output mode, the switching device 104 receives the sound source signal AS1 from the sound source processor 108, and transmits the sound source signal AS1 to the left ear pin LP and the right ear pin RP of the sound source socket 102, and the left ear connector of the sound source socket 102 The foot LP and the right ear pin RP transmit the sound source signal AS1 to the three-loop sound source plug. When the control signal CS2 is at the second level, the mobile device 100 is in the software update mode. In the software update mode, the left ear pin LP and the right ear pin RP of the sound source socket 102 receive the software code SC1 from the three-loop sound source plug, and the switching device 104 is connected to the left ear pin LP and the right ear pin RP of the sound source socket 102.
