Microphone Parts

Before you start making recordings, you should know how to care for your microphone. There are several important parts to keep in mind. These include the Diaphragm, Capsule, Backplate, and Windscreen. If you are not sure which parts you need, read on to learn more. In addition, here are some tips on how to fix your microphone. Listed below are some of the most common parts:


The diaphragm of a microphone is the structure of the microphone’s sound conduction path. Its two halves are connected by sack-like recesses and the pressure gradient on one half cancels out the other. This explains why a cardioid microphone is cardioid in shape. The other half is circular. These two characteristics produce different output frequencies. The most common types of microphones are cardioid and omnidirectional.

The diaphragm is responsible for converting sound waves into electrical signals. The mics have different diaphragm sizes, ranging from 1/2″ to one inch. If the diaphragm is larger than 1 inch, the mic is known as a large-diaphragm condenser. Small-diaphragm condensers, on the other hand, have diaphragm diameters of 1/2”.


A microphone’s capsule determines the pickup pattern it produces. A cardioid capsule, for instance, receives sound from all sides but is best for frontal sounds. This type is housed in a robust shockmount made of rubberized material and rugged external mic wires. This type of capsule also handles extremely loud sounds. The highest-quality cardioid microphones can handle up to 140 dB SPL.

Several types of microphone capsules exist in the market. The K67 is the most popular type, originating in Asia. Its solid brass construction is similar to that of a CK12. This type is known for having aggressive high and mid frequencies with a peak around five or 12 kHz. It is commonly used in Neumann microphones and is compatible with most cardioid and multi-pattern mics.


The design of a microphone is largely dependent on the backplate. Its structure, in addition to the diaphragm thickness, determines the sensitivity, polar response, and PE. This article will discuss different types of backplates, and what each entails. However, the backplate and membrane are not the same thing. In the end, there are millions of possible combinations. But what makes a backplate better than another?

The SUMMiT V process produces both the diaphragm and the backplate. This process produces a diaphragm that is linearly elastic and exhibits a low total deflection. The process also produces a symmetric backplate that is linearly elastic. It can withstand a pressure up to six hundred and thirty dB. Therefore, it has a high sensitivity range.


A windscreen is an essential part of a microphone. Moving microphones are vulnerable to wind noise, which is an annoying low to mid-frequency sound. Often, it is difficult to get rid of the sound with just a microphone. But a windscreen can help keep unwanted drafts at bay. This article will explain the benefits of windscreens and how to choose the right one for your microphone. A windscreen is an essential part of any microphone.

There are two types of windscreens: those made of foam and those made from faux fur. Foam windscreens are typically foam-based, while furry windscreens are made of synthetic flocked materials attached to the foam windscreen. These windjammers reduce wind noise by dispersing the movement of air around the microphone capsule. Furry windscreens like the Azden SWS-100 and SWS-200 are perfect examples. The fur material is longer, so there is less air friction near the mic capsule.


The diaphragm, which is the component opposite the backplate, is responsible for detecting the changes in air pressure. These variations create the sound waves we hear when we talk or sing. The diaphragm vibrates when these sound waves reach it. The varying distance between the diaphragm and back plate causes a fluctuation in the voltage across the capacitor. This electrical signal rapidly fluctuates to reproduce the original sound waves.

A condenser microphone has a back plate and diaphragm that are charged through a capacitor. The backplate acts as the other plate of the capacitor. Both plates of the microphone are charged to prevent any degrading of the audio signal. The distance between the two plates determines the capacitance of the microphone. These measurements can be made by using an online tool to determine the capacitor size. In addition to capacitor size, you can also find out the voltage rating of the microphone.

Diaphragm housing

The physical dimensions of a microphone can affect its frequency response. For example, a large diaphragm microphone is more effective at capturing sounds with low frequencies. Conversely, a small diaphragm microphone will be more practical for use in other applications. In most cases, the diaphragm of a pressure microphone will not move much. However, this can affect its performance if the diaphragm is not perfectly round.

The diaphragm of a moving coil dynamic microphone is typically made of BoPET or Mylar. The latter is more conductive than the former and is less likely to wear out quickly. Despite these disadvantages, however, copper is the most popular material used in moving coil dynamic microphones. Copper is also light (only 8.96 grams per cubic centimeter) and thus produces a powerful audio signal.
