When you hook up the loudspeaker to a stereo, electrical signals feed through the speaker cables (red) into the coil. This turns the coil into a temporary magnet or electromagnet. As the electricity flows back and forth in the cables, the electromagnet either attracts or repels the permanent magnet.
What happens if you put a magnet on a speaker?
The filings trace lines of magnetic force. If another magnet is pushed nearby, it changes the lines of force. Hence, a powerful magnet near your speaker is going to distort the lines of force and distort the sound.
How does a speaker work simple explanation?
Speakers work by converting electrical energy into mechanical energy (motion). The mechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL). When an electric current is sent through a coil of wire, it induces a magnetic field.
Can a speaker work without a magnet?
Abstract: 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.
Does bigger magnet mean better speaker?
The wattage of your speaker is primarily determined by the diameter of the voice coil and the weight of the magnet. Generally a larger voice coil and heavier magnet can handle more power. … This is ideal, but in some cases you may want a speaker with a higher wattage than the amp.
Are magnets bad for your brain?
Studies have shown that it can change the flow of blood in the brain, and turn off neuron groups. Some people, under the influence of high magnetic fields have caused people to have violent seizures, and even lose consciousness, slip into comas, and die.
Are bigger speakers better?
If you have a large room, love bass, and like to listen loud, you need big speakers. It’s not just a matter of louder volume or bass: big speakers just sound better than little ones. When it comes to speakers, size does matter. Big speakers clobber little ones in two ways: they can play louder and make more bass.
Why is the music louder than the talking on my TV?
The louder you turn up your the sound to try and hear it, the more it’s likely to distort over your TV’s speakers, which usually aren’t as capable of handling loud sounds as a stereo system’s. Try adjusting the audio settings on your source (the cable, satellite, or digital receiver) menu.

Do all speakers have magnets in them?
Answer: Every amplifier (speaker) has an electrical current. When the current is changing, it produces a magnetic field. … 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.
Are speaker magnets strong?
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.
How do you make a speaker with a neodymium magnet?

Are Alnico speakers better?
The first crop of speakers in the early 1950s used alnico magnets, which is why some people say they sound more “vintage” than speakers built with ceramic magnets. As the voice coil’s effect lowers the available magnetic field of the alnico magnet, the speaker becomes less efficient, and the voice coil moves less.
