What can you use speaker magnets for?
When it comes to speaker drivers, combining permanent magnets and some sort of conductive diaphragm design would allow us to turn audio signals into sound waves. It is possible to send an electrical audio signal through a conductor and have it move an electromagnetic diaphragm to produce sound.
Can you scrap speaker magnets?
Magnets like ceramic magnets from speakers are low scrap value, but are great and handy tools to have when you are on the road scrap hunting, so make sure not to just throw them out. While most of these magnets have a steel plate attached to them, they still can be worth money to sell to the right scrap yard.
How do you salvage a speaker magnet?
Salvaging Magnets From Speakers. Step 1: Open ’em Up. Okay, now that you’ve found some some speakers (you have found some, haven’t you?) get out a hatchet and knock in the back and then the sides. Step 2: Pry the Magnet Off. This part’s simple. Step 3: Do It Again! Now that you’ve got one magnet, try for 20!.
What can you do with old speaker?
If the Speakers Still Work Turn Old Desktop Speakers Into a Loud Charging Station. You aren’t alone. Make an Internet Radio. Turn Car Speakers Into a Boombox. The Lethargic Option: Add a Chromecast. Repurpose Grills as Earring Holders. Speakers Make Excellent Bookshelves and Wooden Furniture.
What happens if a speaker magnet touches metal?
The magnet is there to keep the coil in place and moving freely to allow wave forms to be produced (music, sound). If the magnet is touching a metal structure (outside force), then the magnetic force is being drawn to that instead of focusing its energy keeping the coil in its place or in motion if that make sense.
What common type of magnet is used in speaker?
Neodymium magnet is commonly used permanent magnet in speakers because of high magnetization and demagnetization, and small-size. electromagnet, which will deform the cone more and produce more sound.
How much are scrap magnets worth?
That means the “melt value” of scrap alnico magnets can be anywhere between $4 / Lb and $7 / Lb (as of December 2019). You will never get paid this much for the scrap, but it should give you an idea of what the value is for the end refiner that buys them.

How do you make a speaker magnet stronger?
If you can find a very strong magnet, repeatedly rub it across your weakened magnet. The strong magnet will realign the magnetic domains inside the weakened magnet [source: Luminaltech]. Magnet stacking One way to make weak magnets stronger is by stacking more of them together.
How do you pull a magnet out?
The easiest method to separating magnets is to slide them apart. When separating magnets keep in mind shear force. Magnets are measured on pull strength, so are up to five times easier to move if they are pushed apart instead of pulled apart. Small magnets slide relatively easily, even without spacers.
What can I do with old wired speakers?
We suggest that you turn your old wired speakers into… wireless speakers! By choosing a Bluetooth adapter to make them Bluetooth enabled, you can connect your smartphone, laptop, and even television to them, making it easy to use them to stream music, movies, podcasts, and other audio.
Are old speakers still good?
No, but there is a lot to say about many things of older speakers. They’re not better simply because they were made to be powered from weaker amplifiers (in general), so they have higher sensitivity, but this usually sacrifices quality somewhere.
What do you do with old speakers and receivers?
Disposing of old or broken home theater systems Give it to Goodwill or the Salvation Army. Recycle broken equipment. Check out Greener Gadgets. Use it as a backup system. Sell it on eBay. Build yourself an internet radio. Continue using the speakers. Sell the equipment yourself.
How do you get neodymium magnets from speakers?
What kind of magnets are used in speakers?
The three different types of materials used in speaker magnets are Alnico, Ceramic (Ferrite) and Neodymium. Each material has a different effect on the tonal characteristics of the speaker. Alnico, the original magnet material used in speakers, produces a classic tone.
