Technical Field

[0001] The utility model relates to the technical field of intercoms, in particular to an intercom with an anti-electromagnetic interference function. Background Art

[0002] There is no need for a network connection between walkie-talkies. Different walkie-talkies can be tuned to a certain channel to transmit and receive different signals through radio. Therefore, the walkie-talkies are equipped with FM knobs and antennas to connect people in different regions in a timely manner, coordinate things and transmit information.

[0003] If there are too many walkie-talkies in a certain area, the signals will easily be mixed together when outputting and receiving signals, which will then cause interference. The stability of the walkie-talkie output signal cannot be guaranteed, and the voices spoken will be intermittent, making it difficult to hear clearly, which will hinder communication.

[0004] Now, a new intercom with anti-electromagnetic interference function is proposed to solve the above problems. Utility Model Content
