Dynamic Microphones

In dynamic microphones a physical cone acts like a lens to concentrate the incoming sound waves. The concentrated energy of these sound waves moves the cone and its attached coil of wire back and forth inside a magnetic field. The magnetic field induces electricity to flow through the wire to produce an electrical signal which is the microphone's output.

The electrical signal is analogous to the original sound wave: the voltage and current are proportional to the original sound.

Dynamic microphones are well known for their versatility and their durability, but are not the best choice for reproducing high and low frequencies; dynamic microphones require significant energy to move the coil of wire and therefore lose definition at the extremes.


Ribbon Microphones

Ribbon microphones consist of a thin strip of metallic foil suspended in front of a magnetic plate. Sound waves cause the foil to vibrate, producing fluctuations in the electrical current, creating the audio signal.

This extremely sensitive configuration picks up a wide range of frequencies and produces an extraordinarily rich representation of the original sound. The trade off for this sensitivity is the delicacy of the mechanism. These ribbon microphones are also sensitive to physical impacts and therefore are not considered portable and can be easily damaged by power overdrive.


Condenser Microphones

Rather than a vibrating wire coil, condenser microphones have a thin diaphragm and solid back plate which make up an electronic component known as a capacitor. As the diaphragm vibrates, the distance from the back plate to the diaphragm varies accordingly. This is known as fluctuating capacitance. It's the fluctuation that produces an electrical current, resulting in the signal output.

Condenser microphones are used for a variety of applications, making them an optimal compromise between the sound reproduction of ribbon microphones and the durability of dynamic microphones.

As a result of the widespread application of condenser microphones, they have evolved into a number of subcategories including electret condenser, cardioid condenser and even dynamic condenser microphones. These specialized microphones represent the largest single category of microphones currently in use and will be discussed in a separate article at a later date.


Choosing Microphones for your Audio System
In this section of our self-help guide, our AudioLink engineers create a checklist to help you choose the microphone that best suits your needs.

In general, you can differentiate among microphones by sound quality, fidelity in the high and low frequency ranges, ease of use, aesthetics, price and warranty. In fact, these same factors impact any choice among pro-audio equipment or accessories - not just microphones.

Some uses are so specialized that we've prepared specific articles to discuss the pros and cons of different microphones. For example, for DJs, KJs and masters of ceremony we've prepared a special article on which microphone solutions best fit their specific needs and budgets.


CHOOSING MICROPHONES FOR YOUR AUDIO SYSTEM - CHOOSING AMONG THE INTERNAL CONFIGURATIONS OF MICROPHONES

Dynamic, Ribbon & Condenser Microphones
Audio engineers and sound technicians classify microphones by dynamic, ribbon and condenser configurations.

Choose a Dynamic Microphone if:
? You want a microphone that will be versatile
? Your budget is limited
? You need a microphone that will be durable
? You use it for live vocals and recording
? You work with relatively loud sound sources

Choose a Ribbon Microphone if:
? You want to pick up a wide range of frequencies
? You are looking for an extraordinarily rich representation of the original sound
? You seek smooth, detailed sound
? You want to capture the subtle nuances in a recording studio
? You expect and appreciate subtle, sensitive sound

Choose a Condenser Microphone if:
? You need versatility because you work in a variety of applications for example speech as well as music
? You want accurate sound reproduction and clarity
? You like sound that is natural, clean and clear, with transparency and detail
? You need exceptionally sensitive pickup, which requires phantom power for silent audio amplification


CHOOSING MICROPHONES FOR YOUR AUDIO SYSTEM - CHOOSING AMONG MICROPHONES PICKUP PATTERNS
Unidirectional, Bidirectional and Omnidirectional

Choose Unidirectional (also called Cardioid) Pickup Patterns if:
? You want to control the source of input
? You want to reject unwanted sounds such as room acoustics (reverberation), feedback or leakage
? You are a reporter and or DJ and hold the microphone to someone while they are speaking
? You are recording concerts where you are miking amps or instruments separately.

Choose Bidirectional or figure 8 if:
? You want to capture the interplay of two sound sources like a vocal or instrumental duet
? You can position microphones above a sound source for ambient room effect
? You do face-to-face interviews utilizing a stationary single microphone
? You want to be very selective about the peripheral sounds the microphone picks up

Consider Omnidirectional or Boundary if:
? You want to deliver the most accurate representation of the total environment
? You need a microphone for a boardroom conference table
? You want realistic recordings of acoustic instruments
? You record vocal groups with three or more singers
? You want to collect sounds equally well from all directions

Consider Switchable Pickup Patterns if:
? You want maximum flexibility
? You want to expand your versatility
? You work in a variety of different vocal applications
? You want a microphone that can be switched from one pickup pattern to another
? You want an all-in-one microphone

เครดิต > Burning Grooves : Introduction to Dynamic and Condenser Microphones

What is a dynamic Microphone?

Dynamic mics are the standard general-purpose mics like the type you see people singing into on top of the pops. The design of a dynamic microphone is very simple and they have few moving parts. This makes them quite rugged and able to withstand high volumes and abuse from hairy roadies.

Dynamic microphones work using the electromagnet principal. The diaphragm vibrates when sound waves hit its surface and this in turn moves a coil of wire back and forth past a magnet. This generates an electrical current that is sent down two wires and out of the mic.

As mentioned previously, dynamic microphones are able to withstand high SPLs so are ideal for recording loud guitar amps and drums. Their resistance to damage also makes them great for the wear and tear of live use. Unfortunately because they are rugged and have a fairly thick diaphragm that is attached to a wire coil, dynamic mics can?t pick up high frequencies well. They also tend to have a bumpy frequency response, which means they colour the sound.

Examples of dynamic microphones :
- Sure SM57 ? Good general purpose instrument mic.
- Sure SM58 ? Great for live vocals.
- Sennheiser MD421 ? Another good general purpose instrument mic.
- AKG D112 ? Designed specifically for kick drums and bass frequencies.


What is a condenser Microphone?

Condenser microphones are much more expensive and fragile than their dynamic brethren. They can generally record a wider frequency range and have a flatter frequency response. Condenser mics also need power either from a battery or in the form of ?phantom? power (+48v) from a mixing desk or mic pre-amp.

Condenser mics work on the principal of capacitance. They have two plates that have a voltage between them. One of the plates is the diaphragm that is usually only a few microns thick and sputtered with gold to make it electrically conductive. The second plate is called the backplate. This is fixed in position and usually has holes drilled into it to allow air to move freely. Condenser microphones generate a signal when the diaphragm vibrates and moves closer to and further away from the backplate. A fixed charge is placed across the two plates and so when they move closer the capacitance increases and when they move away capacitance decreases. This produces an electrical current that can be recorded.

As condenser mics have much thinner diaphragms, they can pick up much higher frequencies and quieter sounds. This makes them ideal for recording just about anything in the studio. Vocals, guitars (acoustic and electric), cymbals and pianos will really come to life when recorded with a condenser microphone. Care does need to be taken when using them for micing up loud instruments as they can distort with high SPLs. Many condensers have a pad switch that makes them less sensitive and less likely to distort.

The only real downsides of condenser mics are their cost and fragility. They can set you back anything from ?100 to ?3000 and up. Due to their design and extremely thin diaphragm, they are not very robust. If you drop a condenser that may be the last time you use it! For this reason (and the fact that they will pick up everything) they are generally not used as much for live work.

Examples of Condenser microphones :
- AKG C414 ? Excellent all round studio microphone.
- Neumann U87 ? Excellent, but pricey all round studio microphone
- Rode NT2 ? Great budget microphone.


Conclusion
If you?re looking for a general-purpose microphone for your home studio, a decent quality condenser mic would be a good option. You can pick up a very respectable performing condenser such as a Rode NT1000 for around the ?160 mark. If your budget can stretch to it, AKG?s C414 is a great, versatile, multi polar pattern mic for around ?600.

For live use Sure?s dynamic SM58s are great vocal mics and their SM57s will do your amp proud. For instruments that need higher frequencies to be picked up, AKG?s C1000s is a solid performer and is surprisingly rugged for a condenser.

เครดิต > MediaCollege.com : How Microphones Work

Condenser Microphones
Condenser means capacitor, an electronic component which stores energy in the form of an electrostatic field. The term condenser is actually obsolete but has stuck as the name for this type of microphone, which uses a capacitor to convert acoustical energy into electrical energy.

Condenser microphones require power from a battery or external source. The resulting audio signal is stronger signal than that from a dynamic. Condensers also tend to be more sensitive and responsive than dynamics, making them well-suited to capturing subtle nuances in a sound. They are not ideal for high-volume work, as their sensitivity makes them prone to distort.

How Condenser Microphones Work

A capacitor has two plates with a voltage between them. In the condenser mic, one of these plates is made of very light material and acts as the diaphragm. The diaphragm vibrates when struck by sound waves, changing the distance between the two plates and therefore changing the capacitance. Specifically, when the plates are closer together, capacitance increases and a charge current occurs. When the plates are further apart, capacitance decreases and a discharge current occurs.

A voltage is required across the capacitor for this to work. This voltage is supplied either by a battery in the mic or by external phantom power.


The Electret Condenser Microphone
The electret condenser mic uses a special type of capacitor which has a permanent voltage built in during manufacture. This is somewhat like a permanent magnet, in that it doesn't require any external power for operation. However good electret condenser mics usually include a pre-amplifier which does still require power.

Other than this difference, you can think of an electret condenser microphone as being the same as a normal condenser.
