The dynamic microphone is one of the major types of microphones. It is a type of microphone in which sound waves cause a movable wire or coil to vibrate in a magnetic field, thereby inducing a current. Dynamic microphones are widely used for live performances, podcasting, vocal recording, streaming, and more.
On the other hand, a condenser microphone is a type of microphone that uses a capacitor (or condenser) to convert sound waves into electrical signals. It consists of a diaphragm placed close to a backplate, forming a capacitor that varies capacitance as sound waves hit the diaphragm. This design allows for greater sensitivity and a wider frequency response, making it ideal for capturing detailed audio. In this article, we will explore the main difference between dynamic and condenser microphones and what is phantom power on a microphone.

Understanding the difference between dynamic and condenser microphones helps you choose the right mic for your specific needs. Each type has unique characteristics, such as sensitivity, durability, and sound pressure handling, which make them suitable for different applications, environments, and audio sources.

Types of Dynamic Mics

There are two main types of dynamic mic: moving coil mics and ribbon mics. Moving coil mics are the most popular and commonly used type of dynamic mic. They are sturdy, and don’t require a power source to work. Maono PD400X is an example of moving coil mics. Ribbon mics are much more delicate and have to be handled very carefully. They are able to record natural sound of instruments.

The price of moving coil mics ranges from 20 USD to 1000 USD. In comparison, the price of ribbon mics are far more expensive. Most of them are 1000 USD or up.

The sensitivity of dynamic microphones, the measure of the microphone's ability for converting acoustic pressure into an electric voltage, generally ranges from -50dB-70dB. Thus it requires 50dB-70dB gain offered by audio card or podcast studio when you are using a dynamic microphone. Otherwise, you won't be able to record with a proper audio signal output level.
