Coils of copper wire are wrapped around the magnets. The music in your radio is converted to electrical pulses that move thru those copper wires wrapped around those magnets. The direction and strength of those electrical pulses causes them to have a magnetic reaction with the flowing electricity. This magnetic reaction is connected to a moving mechanism that is attached to your speaker cone. The way the cone moves back and forth from this coil reacting to the magnet recreates the sound coming from the radio station
So the magnet is just to turn your speaker into a big electromagnet that moves like a solenoid in response to changing electrical impulses that duplicate the sound generated. The magnet has a constant field, but the coil of wire is the electromagnet but it reacts to permanent magnet. Usually the bigger the permanent magnet the bigger the sound the speaker can produce because it can generate stronger pulses from that solenoid coil that reacts to the magnet under electrical impulses

Why bar magnet is not used in speakers?
Bar magnets are not typically used in speakers because they are relatively large and heavy compared to other types of magnets, making them less practical for the size constraints of speaker designs. Additionally, bar magnets can lose their magnetism over time due to demagnetization, which could affect the performance of the speaker. Instead, smaller and more powerful magnets, such as neodymium magnets, are commonly used in speakers.
Do stereo sets have magnets?
The speakers in a stereo contain powerful magnets.
What are the uses of super magnets?
Super magnets are used to help produce sound in speakers. They also help pick up vibrations in electric and bass guitars. These magnets come in many different forms.
Does a radio have any magnets in it?
Yes, just look in the speakers
Do pianos use magnets?
An acoustic piano does not. I do not know about digital pianos. An electronic piano does not need actual magnets. The speakers used to produce the sounds do have magnets in them. Additionally, the electronics may include transformers and wire coils which do become magnetic to some extend while they are functioning.
How do magnets work in telephone?
Magnets are used in telephones' speakers to make vibrations of air (sounds)

Are the magnets on back of speakers neodymium magnets?
no
What do magnets have to do with cell phones?
just the magnets in the built in speakers
What are two devices in a household that use permanent magnets?
Refrigerator doors use permanent magnets to keep them closed and magnets are commonly used in speakers to convert electrical energy into sound by causing the driver (cone) to vibrate.
Where in the cars magnets are used?
Magnets are used in every vehicle built. They are found in the alternator, starter, and speakers of the vehicle. They may also be found used as devices to keep things closed.
What would you use magnets for at home?

Do stereo sets have magnets?
The speakers in a stereo contain powerful magnets.
What is magnetism used for like anything?
Magnets are widely used in motors, generators. speakers and many other things.
What things are in your m3player speakers?
magnets
What are some items that uses magnets?
Sound speakers, metal chip indicators in engines, iphone: compass, refrigerator magnets speakers...
How are magnets used in speakers to produce sound?
Magnets in speakers create a magnetic field that interacts with an electrical current, causing the speaker cone to move back and forth. This movement creates sound waves that we hear as sound.
