With the advancement of globalization process, the cross-regional traffic volume continues to increase, and people have more and more demands on multi-party teleconferencing, and in this background, teleconference takes place. Compared with the traditional conference, the teleconference has the characteristics of rapid arrangement, no regional limitation, low cost and the like. Today, telephone conference is not limited to two-party call in traditional telephone communication, but communication between three parties or multiple parties can be realized through a communication device such as a conference telephone set, and multiple persons can intervene in communication between each party.

In a situation where multiple participants participate in a conference, it is often necessary for the communication device to have a certain sound pickup range to meet the requirement of picking up voices of multiple participants at different locations. In the case of a large number of conference sites and a large number of participants, it is difficult for one telephone equipment, for example, one conference telephone, to meet the above requirements for use, and therefore, in order to extend the sound pickup range of the telephone equipment, it is usually implemented by connecting an extension telephone equipment, for example, an extension microphone.

Conference telephones on the market today typically cascade microphones in such a way that an RJ9 interface is used to connect the audio lines when connecting the extension microphones. However, such a connection line is generally no more than 2.5m, and the analog signal received by the microphone is easily interfered during the wiring transmission process, and especially in the case of long wiring or weak received analog signal, the sound quality of the finally transmitted sound is greatly influenced. Therefore, the current cascade expansion mode is limited by distance and environment in use, and brings inconvenience to users.
