As shown in fig. 10, the contact electrical connection structure is: the upper assembly section 1 is provided with a first conductor 111, a second conductor 112 and a plurality of third conductors 113 which are separated from each other, and because of the separation from each other, there is no electrical connection among the first conductor 111, the second conductor 112 and the third conductors 113, specifically, the first conductor 111, the second conductor 112 and the plurality of third conductors 113 are metal conductive sheets on a circular circuit board 14, and the circular circuit board 14 is arranged on the bottom surface of the inner hole of the inner connector 11. One or more third conductive bodies 113 may be provided according to the actual situation. The microphone is used for acquiring sound signals and generally has two terminals, and the first conductor 111 and the second conductor 112 are respectively used for electrically connecting with the two terminals of the microphone. Two first conductive contacts 211 and two second conductive contacts 212 are arranged on the lower combined section 2, and the two first conductive contacts 211 and the two second conductive contacts 212 are located on the end surface of the external connector 8, so that the electrical contacts and the electrical conductors can be contacted when the external connector 8 is inserted into the internal connector 11, a microphone circuit is naturally arranged in the microphone, the microphone circuit can be a conventional circuit in the existing microphone, two audio input ports are naturally arranged in the microphone circuit for acquiring audio signals generated by the microphone, and meanwhile, the microphone circuit can work only by supplying power and is provided with a power supply input end for being electrically connected with a power supply 23.

Therefore, the two first conductive contacts 211 need to be electrically connected to the first conductive body 111 and the second conductive body 112, respectively, to connect the microphone to the microphone circuit, so that the microphone circuit can acquire the audio signal generated by the microphone. The two second conductive contacts 212 must be electrically connected, so that the power supply 23 supplies power to the microphone circuit and the microphone circuit can work, thereby realizing the corresponding function of the microphone circuit.

In this embodiment, in the process of freely switching between the combined state and the pre-combined state of the upper combined section 1 and the lower combined section 2, the two first conductive contacts 211 are always in contact with the first conductive body 111 and the second conductive body 112, respectively, and the two audio input ports of the microphone circuit are electrically connected to the two terminals of the microphone, respectively.
