How Do Microphones Work?

Performers of all walks of life consider microphones one of the most essential tools for their trade. Standing microphones are a classic for singers. A wireless microphone is appealing for houses of worship. Cordless microphones like those sold at Musical Nerd help broadcasters present without worrying about cord interference. No matter your trade, microphones are one of the most essential tools in the modern world. It’s a wonder how microphones work because finding a good one is so intrinsic to the success of performances from tv bands to singers. Read on to find out a few answers and how you can extend your knowledge of performance technology in general.

Most microphones have a diaphragm

Wireless microphones, dynamic microphones, and similar devices have a diaphragm that picks up sound waves. The diaphragm is connected to an amplifier. When a sound wave hits the mic’s diaphragm, it vibrates and causes the electric current flowing into the microphone to respond and carry your voice. For example, dynamic microphones have a coil of wire within the mic that vibrates when sound hits its diaphragm.

The way sound affects the diaphragm of a microphone varies depending on how much sound is delivered into the microphone. This sound wave carries to the speaker, which carries the voice through places like large venues and concert halls.

Condenser microphones control sound differently

Some microphones are condensers, and they’re more sensitive to sound waves than your standard microphone. They use a capacitor or two metal pieces that rest close together, to store energy until it’s needed. When the sound hits the diaphragm of one of these microphones it requires less sound to carry farther.

Cordless microphones function a bit differently

Cordless microphones function a bit differently

A cordless microphone like a lavalier microphone can be clipped to the front of your clothes or held in your hand. These don’t require extensive cords but instead use batteries and tend to have a high battery life, making them a good choice for public speakers and singers who have to move around a stage at performances, speeches, and festivals. A transmitter sends sound waves to the receiver, which connects to the diaphragm.

You can buy cordless microphones and other mic accessories from sites like Musical Nerd, which was mentioned at the beginning of the article. They sell portable options that are less expensive than traditional or dynamic microphones.

Become an electric engineer to learn more

If this small walkthrough of the different types of microphones and how they work sparked something in you, consider getting a bachelor’s degree or higher in electrical engineering. You’ll be able to design and oversee the construction of electric systems including how microphones are made and how energy systems work in the electronics field.

You can join an electrical engineer online program if in-person isn’t something you’re able to do. The online program probably is just as accredited as an in-person degree program. Tuition for online programs tends to be less costly, and there are plenty of scholarship options. You can earn and develop practical experience and train with experts in your specialization. Earning your online degree as an electrical engineer can open up many career paths for you, and maybe you’ll be making cool wireless microphones for sites like Musical Nerd to sell and performers, singers, public speakers, and more to use.

Ultimately, Microphones are important to our society, workplaces, and personal projects. They allow people to communicate with each other over long distances, which is essential for businesses, governments, and other organizations, especially in a world where computer communication is at a high. Entertainers, students, and music mixers working the radio waves can use a good microphone.
