Salvaging Magnets From Speakers.: ''Tis the season to salvage junk! Where I live, poeple put out big piles of trash every year in April. It''s amazing what one can find. Last year I must have found 15 or 20 speakers. I first found out about rare earth magnets from the Smash Lab
To separate one magnet from another, you''ll need to pull with a force equal to the listed Pull Force Case 1 number. This can be difficult if the magnet is strong, or if there isn''t much area to grab onto the magnet. Most methods of separating these magnets do two things:
6/15/2008· The old 80''s JBL speakers had a real problem with the bonding coming loose, but to actually break a magnet you had to let the raw speaker have a hell of a drop onto concrete to break the magnet in half, even then it would have to hit right on the magnet. Are these Neodymium magnets? G. Guest Guest. Jun 17, 2008
4/16/2014· This 4 minute tutorial will show how you can safely and easily remove any magnet from a speaker housing using only basic tools.
6/6/2005· The magnets are magnetized prior to assembly. One magnet geometry can be used for different speaker geometries while requiring only one set of fixtures for the magnet type. Otherwise, more fixtures would be needed. For remagnetizing, try forming your own coil and putting the speaker in (after checking poles with a compass).
7/30/2007· If the magnet(s) really have fallen off, you''re out of luck. There''s no real way you can reattach them in a way will work the alignment of the magnet to the voice coil is absolutely critical, and it''s almost impossible you''d be able to do it even if the coil wasn''t already damaged as the magnet came off, which it may be.
What Is Speaker Magnet? The neodymium speaker magnet produces a magnetic field, and the speaker''s voice coil motor is placed in the magnetic field. When the voice coil passes through the audio current, the current will be acted by the magnetic field, which causes the voice coil to vibrate, and drives the paper basin that sticks to the voice coil to produce sound.
Using a balloon, magnet, and wire, you will see how to make a speaker. The sound quality is impressive, and volume can be increased with stronger magnets.
Building a round magnet structure makes sense because all the modern tooling is set up for the parts and round magnets are readily available. In short, the product of the magnet structure is a ringshaped radial magnetic field in a round gap. There is nothing about a square magnet structure that can do this any better than a round one.

4/2/2013· Certainly a heavier magnet is not ideal for an already heavy amp or mutlispeaker cabinet and 10 is not much money for a) neo and b) to match sensitivity more appropriately. I want to pair a "Blue" and "V30" and I want to go ceramic for the cost and the articulation (les compression than Alnico with an already compressed Mesa).
Some of our magnets are strong, really strong. If you''ve ever ordered any neodymium magnets from us, or have simply experimented with high powered magnets, you know that once opposite poles attract, it can be tough to separate them. Also, getting in the way of two attracting poles is dangerous and could result in broken glass or bones. When using strong magnets it is important to follow
This extra wire will be used to attach your speaker to a music source. Tape the second coil on top of the first. Next, place your disc magnet on top of the two coils. It doesn''t have to touch all of the wire for your speaker to work, it just has to be attached in some places.
1/19/2010· Car speakers usually have around 20 W rms capacity. Most of them would use Alnico magnets which are powerful enough for your intended purpose if you can find a small enough magnet. You can remove the magnet glued to the body of the speaker by immersing the speaker
6/26/2007· The easiest way to determine the kind of magnet it is, is to heat it to 180 degrees farenheit. If it loses its strength mostly or completely then it has neodymium in it. 0 1. Anonymous. 1 decade ago. It''s a very powerful magnet. be careful, when you put it next to your computer or credit cards. can erase data, permanently. 0 0.
12/17/2008· A speaker will average the electrical energy of a square wave as the fundamental period of a sine wave, with discordant third harmonic resonances. A speaker responds only to the resultant energy of an electrical signal, but not to the separate characteristics of
9/17/2020· my 1930 echophone s3 has a shot speaker that i made sort of work but i would really like to replace. i think it has an electrodynamic speaker thoigh i did not do much research. is there any way i could replace it with a new permanent magnet speaker. the old speaker has a coil on the back with 3 wires coming out and going into the chassis somewhere, and two more for the output transformer
Place the speaker on a heatresistant surface and apply heat with the heat gun gradually, making sure to heat the rear of the speaker evenly. This is where the magnets are located, which you can test by seeing if they will attract your screwdriver.
The speaker is held in place by a large bolt on the back side of the speaker box that attaches the box to the magnet on the speaker. The only way to get it out is to remove the entire box from the
3, the speaker magnet is bigger, the louder the sound Many people will definitely answer, that''s for sure, in fact, the speaker of the stereo is not the bigger the magnet, the better: because the magnet is divided into high density, low density, strong magnetic, weak magnetic, etc.
The best way to do it is by turning the screwdriver between the magnet and the basket and the speaker and with a lot of strength pry them apart. it will be hot,,so heavy gloves..a puddy knife rather than a screw driver once the outer casing is off will work to separate the magnets.
Alex''s Fix loose wires rips in Mylar Magnepan. Remove/separate the magnet/Mylar (the metal frame that holds the is the central part of the speaker), separate it from the frame Carefully pull off the metal braces that run across the width of the front side of the speaker (this allows the speaker to curve a little more You may even want to flex the speaker, or brace or have someone flex the
To remove a magnet in a speaker, first detach the grill in the front of the speaker, second unscrew the speaker after that remove the speaker from the cabinet and cut the speaker cone. Lastly
