Sound is made by pushing air with the cone. A coil of wire is attached to the cone. The "sound"current is passed through the coil. Any current running through magnetic flux causes the coil and cone to move. The larger the magnet the louder the sound. A strong permanent magnet is used. Electromagnets are not used, however

Does a phone use electromagnets?
Yes, phones use electromagnets in various components such as speakers and vibration motors. Electromagnets are used to convert electrical signals into sound waves in speakers and create vibrations for notifications in vibration motors.
What are two common objects which contain electromagnets?
Two common objects that contain electromagnets are speakers and electric door locks. Speakers use electromagnets to convert electrical signals into sound waves, while electric door locks use electromagnets to control the locking mechanism.
How do loud speakers use electromagnets?
yellow cable from pioneer stero to my car which coler have to conect
Do vacuum cleaners make use of electromagnets?
Most vacuum cleaners do not use electromagnets. They typically rely on an electric motor to create suction for cleaning. Electromagnets are typically used in applications like speakers, doorbells, and MRI machines.
What are the objects that use electromagnets?
Speakers! All speakers are is a magnet on the back of a cup to push air. More complex than that, but its a general jist of it. An alternator in a car is another one. Check out http://en.wikipedia.org/wiki/Electromagnets#Uses_of_electromagnets for a good list.
Do TVs use electromagnets?
Yes, TVs use electromagnets in the form of electron beams in a cathode ray tube (CRT) or in the speakers to produce sound. Electromagnets help manipulate the electron beams or produce sound waves, contributing to the functioning of the television.
Where are electromagnets used in the home?
Electromagnets are used in many things such as in televisions, blenders, doorbells, and speakers
What are some objects that contain electromagnets?
Some objects that contain electromagnets are doorbells, speakers, printers, and calculaters
What are some items that use electromagnets?
Some common items that use electromagnets include electric motors, MRI machines, speakers, and relays. Electromagnets are also used in various electronic devices such as doorbells, computer hard drives, and magnetic locks.
Do radios use magnets?
Yes, they do. You need small electromagnets in the speakers so that you can hear the radio station. The incoming radio signal is converted to an electric current by the aerial, boosted by circuit boards in the radio, then transmitted by the speakers by using the current to vibrate the electromagnets.
Examples of electromagnets and their uses?
MRI machines use powerful electromagnets to produce detailed images of the inside of the body. Electric door locks use electromagnets to secure doors when electric current is applied. Maglev trains use electromagnets to achieve high speeds by levitating above the tracks without friction. Speakers use electromagnets to convert electrical signals into sound waves.
How laptops use electromagnets?
Laptops use electromagnets primarily in their hard drives to read and write data. The electromagnets assist in moving the read/write heads over the spinning magnetic disks within the hard drive. Additionally, electromagnets may also be present in components like cooling fans and speakers within a laptop.
