Speaker magnet structure creates the standing magnetic field. A strong standing magnetic field potentially allows greater cone motion. The stronger the magnetic field is, the further it spans thus allowing a voice coil’s field more to push off. The voice coil and standing magnetic field are what makes the cone move. In a loudspeaker, the structural displacements of the voice coil impose a 20Hz-20 KHz vibration of the speaker cone membrane, which leads to pressure changes in the surrounding air and creates the sound signal heard by the listener. neodymium speaker driver magnet
Magnetic circuit is composed of one or more closed loop paths followed by magnetic flux. The magnetic flux is usually generated by permanent magnets or electromagnets and confined to the path by magnetic cores, although there may be air gaps or other materials in the path.
