What is a microphone? You all must have seen the microphone, also known as the mic. But many of you may not know this. What is the type of microphone? How does a microphone work? And what are the pros and the microphones?
In the article What is the microphone? I will give complete information about the microphone and share related information; after reading this, you will understand the microphone well.
The microphone is essential in today’s period of computers and the age of digital resources. With the help of the Internet and various applications, you can make video calls, call people far away, any function, and share your voice in noisy places.
People know it as a voice input device. So, without taking up much of our time, let’s first learn about this important article of today: What is the microphone?
What is a microphone?
microphone (mic) A computer Input device (input device) to convert sound into digital form. Through the microphone, we can make sounds on the computer, and through it, we can also type on the computer.
A microphone is often known as a microphone. A sound card is used to connect the microphone to the computer.
Microphones are used for speeches, live performances, and weddings. We can define a microphone as –
Definition of microphone
A microphone is an input device that converts sound waves into electrical and analogue signals. It is used in weddings and speeches, which causes noise pollution.
Inventor of the microphone
Emile Berliner, along with Thomas Edison, invented the microphone in 1876.
How Microphones Work
First, the microphone (mic) must be connected to the computer. To connect a microphone to a computer, your computer must have a sound card and its driver installed. You can install one if your computer doesn’t have a sound card.
After connecting the microphone to the computer, our voice produces sound waves when we speak into the microphone. Inside it is a diaphragm. When sound waves hit the diaphragm, it vibrates, causing the coil to move.
Attached to it is a magnet. An electric current starts flowing when the coil passes through the magnetic field. An amplifier is also connected to the coil. This amplifier amplifies the power coming from the coil. With the help of this amplifier, sound can be sent anywhere, like a computer.
Types of Microphones
microphone (mic) Here are the following types.
- Condenser microphone
- Kinetic microphone
- Ribbon microphone
- Carbon microphone
- Piezoelectric microphone
- Fiber optic microphone
- Laser microphone
- Liquid microphone
All types of microphones are divided into three categories.
Dynamic microphone
The most commonly used dynamic microphone, a moving coil microphone, consists of a magnet, diaphragm, and coil. The diaphragm is connected to the coil, and a permanent magnet is used. The diaphragm is a non-magnetic material.
When sound waves fall on the diaphragm, it vibrates, causing the coil to vibrate out of the magnetic field.
Now, the coil’s vibration causes electricity to flow, which converts the sound waves into electronic waves. These types of microphones are used to handle high volumes.
They are cheap and durable and do not require external electrical power to operate. You must have seen this type of microphone in a live performance.
Condenser microphone
Condenser microphones are susceptible microphones used for tasks such as voice recording. Most are used in the studio, and singers use this type of microphone, which requires a battery.
It comprises a front plate and a parallel back plate called the diaphragm. When sound waves hit the diaphragm, these two plates convert the sound waves into electrical waves.
These types of microphones are susceptible and hence have background noise. Their recording quality is excellent.
Ribbon microphone
Ribbon microphones are high-quality microphones used for piano, horn, and guitar. They use a thin aluminium ribbon to generate a magnetic field.
When sound waves hit this fragile ribbon, it vibrates. The sound starts moving very quickly.
A transformer was needed to increase the voltage, but today’s microphones use magnetic poles.
Advantages of Microphones
Microphones have many advantages, some of which are mentioned below.
- Sound waves can be converted in real time.
- Microphones are cheap.
- Most microphones can withstand loud sound levels.
- Most microphones do not require a power supply.
Loss of microphone
Microphones have advantages as well as disadvantages.
- More memory is required to store the sound file.
- The sound quality of the microphone is not that great.
- Some microphones are so sensitive that they also pick up the background noise.
