Types of Microphone Parts and How to Replace Them

If you’ve ever had to repair a microphone, chances are you’ve had a hard time figuring out which parts are responsible for the varying sounds that you produce. The following article will take a look at Windscreen, Diaphragm, Capacitor, and Series resistor. In addition, we’ll go over the different types of parts and how to replace them to get the best possible sound. Here are some tips:


A windscreen for microphone parts is used to prevent unwanted noise and vibration from the wind and other factors. It is the most effective way to reduce “pops” or plosives, which are speech sounds produced by a small blast of air. These noises can cause distortion in the final audio output. Most windscreens are designed to minimize pops and plosives, but some users misapply them in other situations.

Before choosing a windscreen, you need to determine if you want a pop-filter or a windscreen. Both are essential accessories for recording, but they serve different purposes. A pop-filter filters out unwanted sounds while a windscreen is designed to fit tightly on a microphone. Before buying a pop-filter, it is helpful to consult with a professional to learn which type of windscreen is best for your particular recording environment.


A microphone works by transmitting sound waves from the source. Sound waves move both diaphragms, but they move in opposite directions. The pressure gradient between the diaphragms is greatest at the front and rear of a microphone. The pressure gradient causes one diaphragm to move away from the electrode and the other toward it. This change in pressure produces a change in the capacity of one diaphragm.

Microphones come in two types: condenser and omnidirectional. Dynamic microphones work on the principle of capacitors, in which the diaphragm acts as one of two capacitor plates. When a voice is sung, the vibrations of the diaphragm change the distance between the two plates, transforming it into sound. Dynamic microphones are highly sensitive and have a wide frequency response and transient response. They are most commonly used for live performances, such as singing or playing guitar. However, they can be expensive.


A microphone can’t produce sound without a capacitor, and a good one will need to be able to handle the highest audio frequencies. Capacitors are much more sensitive than their dynamic counterparts, and they require much less amplification. This makes them ideal for quiet sound sources, where a louder sound will cause the capacitor to go into overdrive. These capacitors can also be thinner than the diaphragms of most microphones. The typical capacitor mic has a thin gold coating on the back plate and diaphragm.

Microphones, like any other electrical device, have two different types of capacitors: electret and non-electret. Both types of microphones have stationary and moving parts, and each plays a vital role. In general, microphones convert acoustic energy into an electrical signal by applying a small voltage across a high-load resistor. This voltage is then converted to an electrical signal by a buffer amplifier. The amplifier uses an internal battery or phantom power line to convert the signal.

Series resistor

A series resistor for microphone enables you to record your voice with a high level of quality. Unlike a microphone preamplifier, which can only receive AC signals, the series resistor provides an output voltage threshold. The voltage VTH sets the maximum swing of the output signal. In addition, the output is locked to this level until the input signal is reduced. This feature can be disabled by connecting the TH to the microphone preamplifier’s input terminal, MICBIAS.

Most electret microphones have two terminals – the Positive and Negative. Some electrets have lead wires attached, while others are soldered to the microphone’s surface-mount pad. When you’re soldering, be sure to pre-tin the ends of the resistor. Then, connect the leads to the microphone’s pad. Be sure not to overheat the microphone’s pad, as too much heat can damage the sensor.
