Condenser Microphones

Condenser microphones are devices that have high-impedance. They require that the amplification is located near the sensor itself. Usually, an amplifier limits their dynamic range. The most usual material to make them is stainless steel, although there’s the option of other similar metals. This type of microphones is steady at varying temperatures and environmental changes.…

Dynamic Microphones

Through the process of electromagnetism, dynamic microphones are able to convert sound into electrical signals. The assembly of a dynamic microphone is simple and quite similar to the structure of a loudspeaker. Its construction is delicate and it responds to low pressure levels. In fact, these are light enough to react to high frequencies without…

Ribbon Microphones

Ribbon microphones are exceptional. The first ribbon microphone that became commercially available revolutionized the audio recording and broadcasting industries. In particular, history knows this microphone as RCA Photophone Type PB-31. Soon after it appeared, the BBC-Marconi Type A microphone came into being. These facts aside, the development of ribbon mics emanated from field coins and…

USB Microphones

USB microphones are different from conventional ones because they join both preamplification and digitalization stages into one single unit. Its design is to interface perfectly with a computer using only a digital connection. This type of microphones include a sensor component within the same device. There are also ADC interfaces, common in conventional analog microphones.…

Stereo Microphones

Stereo microphones use a specific technique that involves a combination of two microphone capsules into a single housing for conventional stereo recordings. The most common combination for this is condenser microphones, dynamic microphones, and ribbon microphones. Stereo Microphones: Stereo Milking Stereo miking is a widely popular technique. It uses a combination of microphones that create…

Ceramic Microphones

Ceramic microphones are a new version of crystal microphones. They are much more stable and widely shock-resistant, especially when compared to electromagnetic microphones. The operation of this type is fairly simple because it is based on a sound that can move a diaphragm. A bar or a pin connects this diaphragm to a piezoelectric material.…

Carbon Microphones

Carbon microphones are devices with high output levels and low impedance. Plus, they tend to be pretty affordable. Nevertheless, they have a limited frequency response. As dynamic microphones and condenser microphones became more affordable, carbon microphones lost their popularity. Before delving into its features, here’s an interesting fact. Thomas Edison patented the first carbon microphone…

Fiber-Optic Microphones

Fiber-optic microphones are EMI/RFI immune. Electrical, magnetic, electrostatic, or radioactive fields do not impact them. They do not react to these, either. Therefore, their design is ideal for settings where the use of traditional microphones is dangerous or ineffective. For instance, these scenarios include places like industrial turbines and MRI equipment setups. Additionally, Fiber-optic microphones…

Electret Microphones

To talk about electret microphones we first need to talk about electret materials. Electret materials have been known for a long time. Some people suggested they were an important component for condenser microphones. Nevertheless, these seemed impractical before the creation of foil electret. And what is a foil electret, you ask? Well, this material involves…

Laser Microphones

Laser microphones are devices that detect sound vibrations in a distant object. As this suggests, they can be used to eavesdrop with a minimal chance of exposure. For this reason, they are common within the surveillance industry. These microphones originated from the idea of eliminating distortion from old-style microphones. Laser microphones are still in an…
