The upper slot ιΐ2 is inserted in 112, the second detecting circuit 104 detects the inserted slot connector type by using α; the audio processing circuit _ is used to process the sound source signal on the receiving module; and the operation signal output circuit 106 is used. The control signal outputted by the processing circuit 1〇2 determines the signal to the slot 丨12. In the case of the output embodiment, the slot 112 on the receiving module 1357269 110 is a slot of four-terminal signals, and the slot of the four-terminal signal is used to receive a connector 114 of a digital microphone. The connector 114 includes a first working voltage terminal DVDD, a clock signal terminal clk, a data signal terminal and a second operating voltage terminal gnd. The operation principle of the first embodiment will be described in more detail below. Please refer to FIG. 1 again. When the connector 114 of the digital microphone is not inserted into the slot 112, the contact 5 in the slot 112 is short-circuited with the contact ό. State, in this case, the switch Q coupled between the audio processing circuit 丨〇2 and the receiving module has a gate voltage of 0V, that is, the switch Q1 is in a state of being turned off (Turn_〇ff), therefore, A detecting circuit 8 outputs a corresponding first detecting voltage Vdetl to the sensing pin sense_b of the audio processing circuit 1〇2 for the audio processing circuit 102 to determine whether the slot 112 has a connector inserted. Then, the audio processing circuit i 〇 2 can determine that the slot 112 has no connector insertion by the internal hardware circuit or the system software according to the voltage value of the first detection voltage Vdetl. When it is determined that there is no connector insertion, the audio processing circuit 1〇2 outputs a control signal to the switch Q2 in the operation signal output circuit 1〇6 through the control pin UNE2_vrEF〇 to turn off the switch Q2, the switch Q3 and the switch q4, The disable operation signal is output to the slot 丄12. It should be noted that, in the embodiment of the present invention, the operation signal can be a clock signal or a working voltage signal, wherein the clock signal is output by the DMIC-CUC pin _, and the working power signal is powered by The crystal Q4 is output, but the invention is not limited thereto.

In this state, since the connector 114 of the digital microphone has been inserted into the slot 112, the second detecting circuit 104 also outputs a corresponding second detecting voltage Vdet2 to the data pin DMIC_DATA t ' It is judged by the audio processing circuit i 〇 2 to judge the type of the connector to be inserted. According to an embodiment, the second detecting circuit is a resistor Ri, and one end thereof is coupled between the audio processing circuit 102 and the receiving module 11A, and the other end is coupled to the operating voltage 33V. As described above, when the audio processing circuit 1〇2 determines that the connector 114 of the digital microphone has been inserted into the slot 112 according to the first detection voltage Vdetl, the hardware circuit of the internal microphone and the system software re-detect the data pin. The second detection voltage of C_DATA is used to judge the type of connector to be inserted. In the embodiment, the inserted connector is a digital connector; then, the audio processing circuit 102 is controlled by the control pin UNE2_vref〇. In the signal-to-operation signal output circuit 1G6, the enable or turn-on switch Q2 and the switch Q3 are turned off q4 to output the clock signal CLK and the operating voltage 3.3V to the connector 114 of the digital microphone to read the sound source signal on the microphone. In addition, in order to drive the microphone smoothly, the amount of current supplied to the microphone is larger than the amount of current in the general integrated circuit. Therefore, the switch Q4 in the operation signal output circuit 206 can be powered by a power according to an embodiment. The crystal realizes (Pt)wei· _) to provide a large amount of current to the microphone and prevent the phenomenon that the transistor Q4 is burned out when the current is overdated.
