Can speakers work without magnets?
A lightweight speaker is constructed without permanent magnets by providing two coils, one of which is mounted on a movable membrane and the other of which is mounted on a fixed frame. The other coil receives the source signal only indirectly, preferably via a bridge rectifier.
What happens if a speaker magnet touches metal?
The magnet is there to keep the coil in place and moving freely to allow wave forms to be produced (music, sound). If the magnet is touching a metal structure (outside force), then the magnetic force is being drawn to that instead of focusing its energy keeping the coil in its place or in motion if that make sense.
Do speakers have permanent magnets?
One of the speaker’s magnets is a permanent magnet (meaning that it is always magnetized) and the other is an electromagnet. Speakers have two magnets. An electromagnet is just a coil of wire wrapped around a hunk of iron.

Can a magnet damage a speaker?
The filings trace lines of magnetic force. Hence, a powerful magnet near your speaker is going to distort the lines of force and distort the sound. Keep your magnet away and the speaker should be fine, unless you are keeping very powerful magnets around the house.
Can you mount speakers to metal?
The most common practice is to add a layer or two of butyl damping material (sound deadening) to the metal around the speaker. If your installer is constructing a set of speaker mounting adapters, then ask if they are using a material that has some mass to it.
What do magnets do to speakers?
To make the cone (or panel) of the speaker move, magnets are used to create an opposing magnetic field which creates vibrations. Speakers often contain large magnets inside of them, as a larger opposing magnetic field creates more vibrations. The larger the magnet, the louder the speaker.
Is a bigger speaker magnet better?
The bigger the magnet, the stronger the potential driving force of the speaker (assuming the magnetic strength of the magnet is constant). Small magnets are for small speakers and produce, by nature, “weaker sound”, while bigger magnets make bigger speakers capable of producing louder sound.
What is the best magnet for speakers?
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.
