    Microphones
    A microphone is a device that captures audio by converting sound waves into an electrical signal. This signal can be amplified as an analog signal or may be converted to a digital signal, which can be processed by a computer or other digital audio device.
    Dynamic
    Dynamic - Dynamic microphones are the most widely used microphones. They have a simple design that includes a magnet wrapped by a metal coil. A thin sheet called a diaphragm is placed on the front end of the magnet and transmits vibrations from sound waves to the coil. The coil then transfers these vibrations to electrical wires that transmit the sound as an electrical signal. Since dynamic microphones use a simple design, they are typically very durable and do not require electrical power.

    Condensor
    Condenser - Condenser microphones are commonly used for audio recording purposes. They are known for their sensitivity and flat frequency response. Each condenser microphone includes a front plate (the diaphragm) and a back plate that is parallel to the front plate. When sound waves hit the diaphragm, it vibrates and alters the distance between the two plates. This change is transmitted as an electrical signal. Unlike dynamic microphones, condensers require electrical power. This current may be provided by an internal battery, but is most often provided as 48 volt "phantom power" from an external preamp or mixing console
    Ribbon
    Ribbon microphones are also known for their high fidelity. They contain a thin ribbon made of a aluminum, duraluminum, or nanofilm, which is suspended in a magnetic field. Incoming sound waves make the ribbon vibrate, generating voltage proportional to the velocity of the vibration. This voltage is transmitted as an electrical signal. While early ribbon microphones required a transformer to increase the output voltage, modern ribbon mics have improved magnets that provide a stronger signal – in some cases even stronger than dynamic microphones. Though ribbon mics have been largely replaced by condensers, several models are still manufactured and used today.
