Dynamic Microphone: The dynamic microphone is cone-shaped on the top that concentrates the sound waves because of its dome shape that serves as a  lens.   This serves to move the diaphragm which creates the electric current that runs through the wire that is coiled around the magnet. These types of microphones are unidirectional.



       Condenser Microphone: The condenser microphone has no wire or coil, but rather just two parallel plates (poles) with a back plate that serves as a capaticor. This, instead, creates the electrical current from the sound waves.



        Ribbon Microphone: The ribbon microphone has a thin metal strip (ribbon) instead of a diaphragm between two plates (poles), which makes it similar to the condenser microphone.
