Microphone & its types

A microphone is a device that converts vibrations into sound electrical signals or put them into a sealed medium. The microphone allows a wide range of communications-related media, as well as music and electronic broadcasts.

Microphone are  Designed

Microphones are often designed for a specific purpose. The point is, unlike the nature of art, it is a record. The simplicity of the microphone is reflected in the design of the microphone. All directional microphones are good at detecting all ambient sounds, but they are weak enough to focus on the target in background noise. Ideal for guided, two-way and point-and-shoot microphone interviews. However, similar results are often associated with bilateral devices, such as the cartilage microphone unit.

First Microphone

The first was a liquid electric microphone system, attached to the cover using a sulfuric acid solution. It cannot copy hard speech to understand the first microphone.

Types of Microphones

Since then, there are still many types of microphone technology, some of which are described below:

  1. Diaphragm Microphone
  2. Carbon Microphones
  3. Condenser Microphones
  4. Crystal Microphone
  5. Dynamic Microphones
  6. Laser Microphone

1. Diaphragm Microphone

Diaphragm Microphone

The Diaphragm microphone, the first of its kind, uses a needle plate that transmits vibrations to special metal devices. After the needle was filtered and passed through the needle, the process was then converted into sound transmitted through the same metal diaphragm.

2. Carbon Microphones

Carbon Microphones

The Carbon microphones has been used for cell phones for over a hundred years. The machine uses carbon dioxide, which converts atmospheric waves into electrical signals.

3. Condenser Microphones

Condenser Microphones

The Condenser microphones use different types of electrical loads than capacitors and diaphragms which act as a single capacitor. A fixed charge map remains the same, often in combat and increases the signal. The size of the aperture, along with the other bits, varies to find the sound in the electrical signal. The electric microphones used in cells and meters are a type of condenser microphone that uses a polar ferrous material.

4. Crystal Microphone

Crystal Microphone-

The Crystal microphone uses a piezoelectric crystal, which generates a small amount of electricity in the diaphragm to provide a memory signal.

5. Dynamic Microphones

Dynamic Microphones

The Dynamic Microphones use flexible coils suspended in a magnetic field that can be connected to multiple diaphragms for extended frequencies. They use electromagnetic induction to generate signals. These microphones are great for performance.

6. Laser Microphone

Laser-Microphone

The Laser Microphone uses dynamic surfaces to remotely record sound waves in damaged sound waves. The lasers return to different places due to the vibrations and these changes are transmitted to the sound waves.

Due to the similarity in their functions, the microphone can be used as a speaker. In general, microphone-produced speakers are ideal for high-frequency sounds, such as the super twitter microphone received by STC. Although generally designed for greater comfort, speakers can also use a microphone.

Uses of Microphone

Microphones are used in many applications such as telephones, hearing aids, announcement systems for concert courts and public events, production, operating and live sound recording, recording, dual radio, sound and broadcasting, radio and television.

Microphone for Computer

Microphone accessories and input devices were invented by Emil Berliner in 1877. Microphones allow computer users to record sound on their computers. Instructions and support for microphones and templates.
