Mutual wireless communication
When the current in a coil changes, not only will the self-induced electromotive force be generated in itself, but also the electroacoustic electromotive force generated in the coil that is adjacent to it. The currents of the two coils can provide magnetic induction flux to each other. When the current changes In the other circuit, the phenomenon of stimulating the acoustic electromotive force is called the mutual inductance phenomenon. The mutual dryness is proportional to the number of turns of the two coils, proportional to the magnetic permeability in the coil, and inversely proportional to the distance of the coil. This exhibit provides an audio signal to a coil through a carrier, through the mutual inductance coupling in the air, the signal is transmitted to a coil inside and outside, and then the speaker is provided to play the audio signal.
