Strong Neo Ring Neodymium Speaker Magnets

Product Details

Speakers are composed of a cone attached to an electromagnet, and a permanent magnet. Variations in electric charge induce changes in the electromagnetic field at the electromagnet and move the cone relative to the permanent magnet, producing soundwaves. A key factor in the function of the speaker, and the topic of discussion for this poster, is that the permanent magnet needs to produce a strong and consistent magnetic field to interact with the variable field of the electromagnet.

The most common permanent magnet among speakers is an alloy, a mixture of metals that is more stable and resistant to corrosion than the constituent metals. Both iron and neodymium have magnetic moments on every atom, because they have several unpaired electrons with the same quantum spin in their outermost electron shells. These magnetic moments on individual atoms can combine parallel to each other among large groups of atoms to form magnetic domains. These domains contain very many atoms which all contribute to make a strong magnetic force which will remain even in the absence of an applied magnetic field, this is a property known as ferromagnetism. The strong and consistent magnetic field produced by this alloy can interact with the variable field of the electromagnet in a predictable manner which can be used to produce specific sounds with the cone.

How a Speaker Works ?

• The speaker produces sound when the electromagnet is enabled or disabled which will cause it and the permanent magnet to attract or repel each other.

• The back-and-forth motion of electromagnet is controlled entirely by the electric current applied to the electromagnet.

• The more quickly the current changes, the faster the cone moves and the higher the pitch.

• More current will increase the electromagnetic force applied to the electromagnet, which will deform the cone more and produce more sound.
