Product Description
Every sound speaker, from the smallest to the most powerful, has a permanent magnet. Located behind the center of the speaker cone, the magnet interacts with a changing magnetic field from an electrical coil. The pushing and pulling forces move the speaker cone rapidly in and out, producing sound. Speaker manufacturers use different kinds of magnets to suit speakers of different sizes and to achieve a range of tone qualities.
To get good sound from a speaker, you need a strong magnet. Neodymium has the greatest field strength of any permanent magnet known. Speakers made with these magnets have good frequency response, and because the magnets are strong, you can use smaller magnets, reducing speaker size and weight.
Neodymium magnets made high-fidelity ear buds possible, as they can pack a strong magnetic field into a tiny package. However, these magnets shatter easily.
Due to the sizes of the magnet, there may be variations on pull strength. Please contact our customer service team for more information.
