Microphone diaphragms, unlike speaker diaphragms, tend to be thin and flexible, since they need to absorb as much sound as possible. In a condenser microphone, the diaphragm is placed in front of a plate and is charged. [2] In a dynamic microphone, the diaphragm is glued to a magnetic coil, similar to the one in a dynamic loudspeaker.
A typical sound reinforcement system consists of; input transducers (e.g., microphones), which convert sound energy such as a person singing into an electric signal, signal processors which alter the signal characteristics (e.g., equalizers that adjust the bass and treble, compressors that reduce signal peaks, etc.), amplifiers, which produce a ...
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording .
Electret microphones require no polarizing voltage unlike other condenser microphones, but normally contain an integrated preamplifier which requires a small amount of power (often incorrectly called polarizing power or bias). This preamp is frequently phantom powered in sound reinforcement and studio applications. Other types include a 1.5 V ...
A Crown Audio brand PZM, the "Sound Grabber II". It is shown with adapters to enable it to be connected to different mixers and audio devices. The mic has an internal battery so that it can be used with consumer audio devices that do not supply phantom power. Boundary mics may have XLR or 1/4" TRS jacks. Some use mini-XLR or 1/8" TRS jacks.
University Sound US664A dynamic supercardioid microphone. The most common unidirectional microphone is a cardioid microphone, so named because the sensitivity pattern is "heart-shaped" (i.e. a cardioid). The cardioid family of microphones are commonly used as vocal or speech microphones since they are good at rejecting sounds from other directions.
The electroacoustic mechanism most widely used in speakers to convert the electric current to sound waves is the dynamic or electrodynamic driver, invented in 1925 by Edward W. Kellogg and Chester W. Rice, which creates sound with a coil of wire called a voice coil suspended between the poles of a magnet.
The U47 was the first condenser microphone switchable between cardioid and omni-directional pick-up patterns. It incorporated the highly successful 12- micron -thick M7 capsule and VF-14 tube amplifier, which was a metal-clad pre-World War II pentode changed to work as a triode .
