Description: How to separate a magnet from the rear of a speaker. These are the old speakers from my truck and as you can see they’re in rough shape. These are strong magnets that can be reused on other projects if you wish. These are two-way speakers, so they have a slightly different design than compared to a one-way speaker. The tweeter in the center will need to be removed, a one-way speaker on the other hand just has a dust cover in the center instead. #audio #recycle #OEMTOOLS Heat Gun: mobiledistributorsupply.com/24498-oemtools-24498-dual-temp-heat-gun-oem Website: 4diyers.com Patreon: patreon.com/4diyers Facebook: facebook.com/4diyers Twitter: twitter.com/4DIYers Instagram: instagram.com/4diyers Tumblr: 4diyers.tumblr.com Pintrest: pinterest.com/4diyers Tools/Supplies Needed: -standard screwdriver -hammer -chisel -punch -heat gun -metal blocks -wire cutters Chapters: 00:00 Intro 00:30 Preparation/Disassembly 03:02 Magnet Removal 03:21 Separated Magnet 03:41 Second Example Procedure: First is removing the tweeter. Designs may vary, these just snap into place. Once removed, there are two wires on the rear which need to be cut. Now is removing the speaker surround, these are just glued into place. You can see mine are completely separated. To remove the cone, spider and coil, use a standard screwdriver to break the glue bond between the spider and basket. The basket is the metal exterior frame of the speaker. Depending on the strength of the glue, you may have to assist it all the way around. Cut the two wires going to the voice coil, this can be done from the outside behind the terminals. A view of the cone, spider, and coil once removed. The wires for the tweeter runs on the outside of the magnet, there is a portion of the cover left. Using a standard screwdriver, remove the cover. Using a round punch, remove the insert which is used to snap the tweeter into place. If yours is a one-way speaker, you most likely will not have this feature so you can skip ahead to the next step. The magnet has front and rear caps, it can be removed with those pieces remaining in place depending on its future application. There are four peened over areas, like rivets. These can be ground down or drilled if you wish. I wasn’t having much luck doing this with the assembly cold. This can depend on the speaker quality, it may have a better quality adhesive used. I had to result to using a heat gun to soften up the adhesive to break down the assembly. Here I’m using my OEMTOOLS 24498 dual temperature heat gun which always helps me get the job done whenever heat is required. Get it hot, but not a temperature exceeding 100C or 212F. Depending on the type of magnet used, excessive heat can damage the strength, so be mindful of that. Using gloves or a rag, flip the speaker over when it’s elevated on the edges of the magnet so you’re able to pop off the center cap. It’s easier if you have a nonferrous metal, one bar I have here is a piece of brass and the other is a steel block. The magnetic sticks to the steel which can be a little tedious to work with. Using a punch, hit on the center portion. This will remove the center portion and rear cap as they’re one piece. If you were to use a hammer directly on this piece, the hammer will stick to the magnet causing some problems. And as you can see the one portion is removed. Again is heating the area, we’re onto the final part of removing the magnet. Using a chisel with a sharp edge, separate the area between the magnet and the cap on the rear of the basket. You may need to work in a couple of areas depending on the bond. Once removed, here is the magnet ready to be reused for another application. Any leftover glue residue can be cleaned off with a solvent like a wax and grease remover. It’s also worth noting, magnets are brittle and can chip or crack very easily. Take your time and be patient when removing them. Thank you to all those who watch my videos and support my content.
