Univ alberta research (Richmond) a loudspeaker consists of three main parts a cardboard or plastic cone a speaker coil which is essentially an electromagnet insulated with paper and wrapped in magnetic wire and a permanent magnet sound is transmitted through speakers when electrical signals pass through the wire generating a magnetic field creating vibration the speaker coil is positioned at the base of the speaker and near a permanent magnet the magnetic field generated by the wiring attached to the base of the speaker cone and the electromagnet is oppositional to the magnetic field generated by the electromagnet and the permanent magnet these opposing forces move the speaker coil and the speaker cone attached to it causing vibration and thus sound Weill Cornell Medical College. https://PaperHelp.space
