How to remove the magnet from the horn

First of all, it is not recommended that you remove the ring magnet of the undamaged speaker.

When the speaker is damaged, you can remove it like this:

1. Remove the paper basin and spring leaf (also called centering bracket or elastic wave, just like waves swinging in water) and voice coil of the speaker, leaving only an empty shelf for the speaker.

2. Remove from between the upper magnetic plate of the magnet and the basin frame. Insert a screwdriver and pry up the basin frame from different angles, leaving only the ring magnet with upper and lower magnetic plates and columns.

3. Find a cylindrical iron block (preferably the lower magnetic column left when dismantling the waste speaker), and the cross-sectional area should be equivalent to that of the removed speaker. If it is too large, it will get stuck on the upper magnetic plate; if it is too small, it will slip unsteadily.

4. After finding it, suck it on the removed speaker pole. Then let the found cylindrical iron block go down, the ring magnet go up and knock it on the ground (cement floor, not on the floor), and the magnetic pole of the lower magnetic plate and the removed speaker will come down. Only the magnetic plate and the ring magnet are left.

5. At this time, from the bottom up, you will find that the inner side of the upper magnetic conduction plate will be one more turn than the ring magnet. Therefore, you can put the lower magnetic plate and the magnetic column that have just been removed back and insert them obliquely into the center of the ring magnet (it will be inconvenient at this time due to the influence of magnetic force). Then, the original magnetic column will be close to the extra circle of the upper magnetic plate. A little is enough. At this time, there will be a gap between the lower magnetic conduction plate and the speaker. Otherwise, the ring magnet is likely to be damaged.

6. Put the magnetic pole of the lower magnetic plate downward. When you knock on the ground, the upper magnetic plate will separate from the ring magnet and make a crisp sound!

7. Finally, you can separate them one by one with a little effort!
