How strong are speaker magnets? Speaker magnet strength ranges from about 0.001 tesla all the way up to about 1.5 tesla (the strongest neodymium magnets). The basic function of speaker magnets is to translate an electrical signal into an audible sound. To achieve this functionality, speaker magnets don’t need to be extremely strong. So why [...]
Some Introduction About Speaker Magnets Speakers are a type of transducer which can transfer the electric signal to the acoustic signal. The sound quality of the speaker is largely depended on the speaker magnets. Speakers can be classified to internal magnetic type and external magnetic type according to the magnetic circuit structure. Speakers also can [...]
Salvaging Magnets from Speakers This is 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 episode ''High [...]
How Speakers Work - Making Sound: Speaker Magnets When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. This changes the magnetic forces between the voice coil and the permanent magnet, moving the coil and attached diaphragm back and forth. How Speakers Work So how does the [...]
