The application of neodymium magnets in electrical appliances is very special, just like in electric motors. Neodymium magnets are made of a mixture of iron, boron and neodymium. Their resistance and the diversity of production methods make them so common in daily life that we can find them in almost any field.
As far as electrical appliances are concerned, neodymium magnets are basically used in audio equipment such as speakers, headphones, and microphones. For example, the speaker is controlled by two magnets and a current. The movable electromagnetic coil is suspended near a fixed magnet, and current flows through the coil very quickly.
When the coil is charged, it will be attracted by the magnet and repelled again, causing the vibration to be amplified and turn into music on your ears. The microphone of course works on a similar principle, because when the coil moves in the magnetic field generated by the neodymium magnet, it generates an electrical signal and reproduces itself in the form of sound.Loudspeaker Neodymium Magnet is your good choice.
