Microphones can be classified both according to transducer principle and by directivity or polar pattern.  Transducer principle is the method of converting one form of energy to another. Since we have already covered transducer principle of an electret condenser microphone (ECM) in a previous blog article , we shall focus on types of electret condenser microphones … Continue reading “Types of Electret Condenser Microphones (ECM) by Polar Pattern”

Operation of an Electret Condenser Microphone (ECM) As we discussed in our last blog Anatomy of an Electret Condenser Microphone, the basic structure of an Electret Condenser Microphone (ECM) is a pair of parallel plates, one of which is a moveable diaphragm, and another is a fixed back plate. A special layer of material called … Continue reading “Operation of an Electret Condenser Microphone (ECM)”

What is a Waterproof Microphone A waterproof microphone is a microphone that could work normally in a certain water environment. Waterproof microphones must meet a set of standards, called IPX, to be classified as waterproof microphones. For example, a waterproof microphone can be rated to IPX7 or IPX8. An IPX7 rating means that a Waterproof … Continue reading “Audio Dictionary: What is a Waterproof Microphone?”

Microphones are transducers. Electret Condenser Microphones (ECMs) have both moving and stationary parts. Each part of an Electret Condenser Microphone (ECM) plays a significant role. Simply put microphones are transducers. As a transducer a microphone converts acoustic energy into electric energy. This is quite the opposite of a loudspeaker driver which converts electric energy into acoustic energy. … Continue reading “Anatomy of an Electret Condenser Microphone (ECM)”
