Generally a sound speaker contain following part.
1 . Voice coil (Sound Transuder)
2.Magnet
3. Diaphragm

Function :

Sound speaker is a device which convert the electrical signal into sounds by the sound transuder. By which we are able to hear or understand the electrical signal into sounds by the sound transuder. 

Sound Transuder :

It is a part of speaker which convert the electrical signal into sounds. A transuder is a voice coil in which a wire wrapped on a metal rod and whole voice  coil setup is situated in a magnetic field (permanent magnet) the voice coil is attached to the diaphragm by which when a electrical signal are applied to the voice coil due to Faraday induction law voice coil are push the diaphragm as well as air present,  between the voice coil and diaphragm. 

Due to continuous this process sounds wave generate on the diaphragm. 

Diaphragm :

It is a part of speaker on which sounds wave are generate. Generally a diaphragm is a semi rigid membrane which is attach to the voice coil in sound speaker. Sounds wave are generate on the diaphragm due to continuous push and pulling forces applied on it by air and voice coil.
