What is an electret condenser microphone used for?
Electret condenser microphones are used to convert sound into an electrical signal and are used in a wide variety of consumer electronic products, including mobile phones, GPS devices, and speech recognition equipment.
What is the difference between electret and condenser microphones?
The difference between the two is that the DC-biased condenser requires an external power supply to provide polarizing voltage while the electret condenser uses a pre-polarized diaphragm or back plate. Most condenser microphones used today are electret.
Do electret condenser mics need phantom power?
Phantom Power While the electret condenser microphone doesn’t need a power supply to provide polarizing voltage, an FET impedance matching circuit inside the microphone does require some power. This may be supplied by a small low-voltage internal battery or by an external “phantom” supply.
What is the difference between electret and dynamic microphones?
Electret Condenser Microphone The thin, lightweight diaphragm makes modern ECMs very sensitive when compared to dynamic microphones, with high-resolution capabilities and an ultra-wide frequency response. Most ECMs feature a housing design that is very small, making them easy to place within many different products.
How do I connect my electret microphone to my computer?
Since the microphone port of a computer provides about 2.3V of power, this will perfectly power the electret microphone. You can connect jumper wires from the 3.5mm audio plug cable and connect the positive side to the 2.2KΩ pull-up resistor and connect the negative side to the ground terminal of the microphone. ‘
Does screaming into your mic break it?
Mics are very resistant to high sound pressure levels and would not break due to yelling. However, some mic diaphragms (like ribbons) are sensitive to blasts of air like vocal plosives. Although yelling is very unlikely to break a mic, plosives (which are common with yelling) may damage the mic.
Do microphones degrade over time?
Microphones, like all electrical devices, naturally wear out. The components within a microphone slowly wear out over time. Time is a major factor in microphone “health,” as is the normal wear and tear of actually using the microphone.
Are electret microphones dynamic?
The dynamic Mic needs an integral amplifier to match the aircraft system; Electret mics include a single stage amplifier in the basic design, hence the higher output, some designs also include an additional amplifier before connecting to the aircraft system.

What is a good electret microphone for recording?
Dynamic Microphones. Dynamic mics work in much the same way as a loudspeaker but in reverse.
How do I Check my electret mic?
with a true condenser mic a relativity large voltage (48 v) Phantom Power powers the mic. an electret mic the metal plates have a static charge applied so the only power required is low voltage to power a transistor amplifier. you know what a capacitor is right? 2 metal plates seperated by air or other di electric.
How to build an electret microphone circuit?
LM386
What are the attributes of a condenser microphone?
– OFF-AXIS RESPONSE & TRANSIENTS. A sound arriving from directly in front of the microphone, perpendicular to the diaphragm, is considered to be on-axis, and is said to be arriving at – EQUIVALENT NOISE LEVEL. – RESONANCE. – INTERNAL ELECTRONICS.
