Microphone Used
For details of microphones for you
Although modern microphones follow the same principle, they do it electronically. And it starts wave pressure in the air and converts them into electrical signals. The microphones are of different types, and they differ in their operation. In general, there are five common types of microphones for different purposes.
Microphones: You are known as capacitors, since the membrane acts as a plate a capacitor that responds to sound waves. The movement is happening that changes the capacitance of the capacitor and is amplified to produce a signal. However, These microphones operate on a small battery to provide a voltage across the capacitor. These microphones produce high quality audio signal, and are often used in studio recording.
Dynamic microphones: These microphones work via electromagnetic induction. In this system, the sound wave creates a vibration in the membrane, making the magnet or the coil to move and this movement generates a small current. However, the microphones very robust and resistant moisture and are very economical. And they are often used for the stage.
Ribbon microphones: These microphones are exposed a thin metal strip in a magnetic field. And by the sound wave in motion that changes the current through it. Ribbon microphones do not require usually no phantom power, but there are ribbon mics and preamps that if the phantom power.
Carbon Microphones: These are perhaps the oldest and simplest microphones that were once used in phones. Carbon microphones used coal dust and they have a membrane thin metal on one side. As the membrane is struck by sound waves, it pushes the coal dust that changes the resistance. By running a current through the carbon, changing resistance changes the amount of current flow and thus generates an electrical signal. Although not not robust enough, they can reproduce high sound quality and have a defined frequency. But this can be used as a kind of amplifiers.
Crystal microphones: These microphones have a diaphragm to a crystal, a signal boxes, when the sound changes affected the diaphragm. Generally, the microphone crystal, the theory of piezoelectricity. However, they are often associated with vacuum tube equipment as tape recorders domestic used.
Apart from these types of microphones, there is another type of microphone is that nowadays commonly used. It is called Wireless Microphones. They are portable and are a versatile way of recording and radio broadcasting without a cable connection.
