The bass speaker, also known as the bass speaker, is one of the affordable speakers that many families often have. There are numerous maintenance methods for the woofer on the Internet, but they all involve peeling off the paper basin or the support. Such methods are not only very difficult to operate, but also particularly easy to damage the paper box and the support. It is not easy for ordinary people to re bond the two. Today, I have summarized several simple methods for you. If you are interested, you can come and have a look!
1. How to remove the dust cover
Most of the woofers were burnt out mainly because the current of the voice coil was too high and was gradually burnt out. This method is to deal with such problems. First of all, we need to find two seemingly simple tools: the straight knife and the scimitar. Both of these knives can be self sharpened by using scrap saw blades. When sharpening, the curved knife should have a greater slope than the straight knife. Don't forget to burn red on the charcoal fire before bending the shape. After the two knives are made, use a straight knife to carve a circle along the paper basin, and then use a machete to peel off the dust cover.
2. How to take voice coil
After removing the dust cover, we can see that the voice coil is glued to the paper basin. At this time, we can use a straight knife to scribe along the adhesion trace from the outside. At the same time, we can feel that the lead of the voice coil is also scratched off. At this time, the gap of the opening has gradually become larger, and the voice coil is easy to take out. Now we can see that the voice coil has been burnt or simply broken. At this time, we should use double-sided adhesive tape to remove all the debris.
3. Rewind voice coil
The next step after removing the voice coil is to rewind the voice coil. Before rewinding, remember to find an object smaller than the original voice coil as the mold. At this time, the original coil is removed. Before and after the process, mark the position and count the turns. Then use the same specification of enamelled wire to start the winding of the new voice coil. Remember to leave enough lead wires, and fix them with adhesive tape at the starting point until the end point. We can use adhesive tape for temporary fixing and apply glue on the surface of the enamelled wire. The same method is used for another layer. Then apply glue to fix it. Then we take out the mold, and a new coil is successfully wound.
So it seems that the maintenance of the woofer is very simple. Today, the small editor only provides you with the repair work of winding the horn voice coil.
