Currently, commercially available speakers are developed to imitate what human beings speak by
the resonance of the throat, but the speakers convert electric energy into mechanical vibration
and propagate sound using air as a medium That is, after the speaker is connected to the current
of the audio frequency through the cable, the current is supplied to the coil in the speaker to
generate the magnetic field effect, and the positive electrode is generated by the permanent
magnets provided at both ends of the coil. When corresponding to the positive electrode, the
