Permanent Magnet Used in Electronics Industry

Rare earth permanent magnet has the most excellent magnetic properties. Its application makes the size of many electronic products further reduced and the performance greatly improved, so as to adapt to the development trend of light, thin and small electronic products.The magnet creates a magnetic field in which the speaker's voice coil is placed. When an audio current is passed through the voice coil, the current is subjected to the magnetic force, causing the voice coil to vibrate, driving the paper bowl attached to the voice coil to vibrate and produce sound.
