What is the soft material in speakers?
If you mean the cone inside the speaker - they're usually made of cardboard. It's light enough to move when the speaker is in use - yet strong enough to support the speakers coil assembly.
How do speaker use electromagnet?
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
Can an electric current move through a electromagnet?
yes.

The slower the coils of an electromagnet move stronger or weaker?
Weaker
How does speakers works?
A speaker consists of one or more magnets, called voice coils, which are mounted at the narrowest part of a cone(s). The cone may be made of paper, cardboard, or Kevlar. When the amplifier receives a signal, it amplifies it, creating current. The current causes the magnet to move, which distorts the cone. When the magnet relaxes, the cone returns to its original shape, after a few oscillations. The cone moving back and forth compresses the air in front of it, causing a wave to travel away from the cone. That wave is the same frequency as the signal the amplifier received.
How do you move cone in twist mountain?
winter
What types of metal can a electromagnet move?
only ferrous metals for example, iron.
What is the purpose for coil in a sound speaker?
The coil is energized by electric current from an amplifier. the current generates a magnetic force that interacts with the loudspeaker's magnet and forces the coil to move this moves the speakers kone to generate acoustic compression waves.
What is one way to move in a large stereo into your house?
One way to move a large stereo into your house is by paying professional movers to help you move it in to insure that it all gets in your house safe and unharmed.
How do I know if my car radio speakers are blown?
Chevy used weak glue to attach the surround to the frame. When you look at a speaker, you see a "bubble" in the middle, that is called the dust cap. From the dust cap the speaker forms a cone to the outside edge of the speaker, this is called the "cone". Surrounding the cone is the "surround". The surround is a convex piece of flexible material that allows the cone to move up and down. If your speaker makes a buzzing noise, it is probably due to the surround breaking away from the frame. If you hear a crackling sound, the speaker is probably blown. The easiest fix is to replace said speaker and its sister. you'll hear a crackling sound in the speakers turn the fade onto the speakers u think r blown and test em individually
Why does a speaker need an electromagnet not a permanent magnet?
One of the main kinds of speakers needs both. Sound in the form of varying electricity is fed through part of the speaker known as the 'voice coil' which is actually just an electromagnet. Since the electricity in it is varying the magnetism produced by this coil varies too. The voice coil is placed close to a permanent magnet and the voice coil is permitted to move back and forth in response to the electricity going through it. A big cone is fastened to the voice coil to transmit the movements of the voice coil to the air more efficiently. Thus overall the permanent magnet and the electromagnet work together to produce the sound waves that we hear from a speaker. For a more detailed explanation go to the How Stuff Works web site and search for speaker.
