Regardless of where, how, and when you use your speakers – in your car, against your wall, on a stage, or beside your bed – nearly all speakers have magnets in them.
Knowing why speakers have magnets in them will help you understand your current speakers or assist you in purchasing your next set of speakers.
This article will address why speakers have magnets and how they work. It will also answer common follow-up questions about electromagnetism in speakers and provide information regarding different speaker magnets.
By the end of this article, you will know a lot more about magnets in speakers.
What are the Main Parts of the Speaker?
The permanent magnet is permanent because it is always magnetized.
The electromagnet is a free-moving coil wrapped around iron. This coil is only magnetized when an electric current is passing through.
The driver is the cone-shaped element of the speaker that has both the electromagnet and permanent magnet attached at the base.
Why Do Speakers Have Magnets?
The purpose of speakers is to produce sound. To do so, they need to be able to create and transmit audible vibrations. Magnets help them to do so.
Speakers have two magnets – a permanent magnet and an electromagnet – that work together within a speaker’s driver to convert and amplify the sound you hear.
They work by helping to produce vibrations when an electric current passes through the speaker and eventually transmits sound waves out into the air.
The following questions and answers will help you understand the functionality of these magnets more deeply.
