Answer 2

Here is a novel approach . Instead of answers taken straight from a text book or an advertisement ( see Mallimar ) . Get hold of an old loudspeaker ! note the cone of cardboard or material ? if you press it gently it will move in both directions in and out !. there are two wires that connect to the cone , you can`t see where they go but if you pulled the cone apart you would see that they are connected to a coil of wire which is wound around the narrow end of the cone which fits closely around a heavyish magnet that is part of the large magnet that makes the speaker so heavy, you can see what I mean when you look at it !Now for the good bit , when the audio from an amp is connected to the two wires then this causes the cone to move in and out in sympathy to the music or speech or whatever. The air pressure waves set up from the cone are detected by your ears as sound , enjoy the music !! Don`t poke your fingers through the cone as this spoils the sound . Don't drop the speaker as this will move the cone off centre and then it will sound scratchy ! Have fun..

In any sound system, ultimate quality depends on the speakers. The best recording, encoded on the most advanced storage device and played by a top-of-the-line deck and amplifier, will sound awful if the system is hooked up to poor speakers. A system's speaker is the component that takes the electronic signal stored on things like CDs, tapes and DVDs and turns it back into actual sound that we can hear.

Electric pulses are sent to a coil of wire which moves a rod of metal -- through a process of electro-magnetism -- attached to a "diaphram" or sheet of material. The vibrations this causes in the air are sound.
