Difference Between a Loudspeaker and a Microphone?

A loudspeaker and a microphone are two very different things. A loudspeaker is an electronic device that converts electrical signals into sound waves, while a microphone is an opposite – it captures sound waves and turns them into an electric signal. Despite their differences, both devices have similarities as well. In this blog post, we will discuss the difference between loudspeakers and microphones to help you understand what each does for your business!

What Is The Difference Between A Loudspeaker And A Microphone?

The short answer is this. Loudspeakers are used to create sound through acoustic or mechanical means. Microphones, on the other hand, convert sound into an electric signal that can be transmitted over a wire or electronically sent from one place to another.

What Is A Loudspeaker?

A loudspeaker is an electronic device that converts electrical signals into sound waves. The most common type of loudspeaker is the cone speaker, which uses a paper or plastic cone to move air and create sound.

How Does A Loudspeaker Work?

When an electric current passes through a wire coil in the loudspeaker, it creates a magnetic field. When the current passes through a second coil of wire, also in the loudspeaker, it creates an electric field that interacts with the magnetic filed and causes changes to air pressure around the speaker cone. The changing air pressure pushes and pulls on neighboring particles creating sound waves which become amplified when they leave the open-air frame of the device.

What Is A Microphone?

A microphone is the opposite – it captures sound waves and turns them into an electric signal. The most common type of microphone uses a thin diaphragm that vibrates in response to the air pressure changes created by sound waves. This causes a conductive coil attached to the diaphragm to move near another magnetically polarized coil, creating a fluctuating magnetic field that corresponds with the sound waves from the original source.

How Does A Microphone Work?

This is a very simple process, and it involves electromagnetism. The two coils in question allow for an electrical charge to travel through them and create an electric current that can be transmitted over wire or electronically sent from one place to another. This current is what captures the sound waves and turns them into an electronic signal.

The Differences Between A Loudspeaker And A Microphone

Now that you know a little more about how each device works, let’s take a look at some of the key differences between loudspeakers and microphones:

  • Loudspeakers are used to create sound, while microphones are used for capturing it.
  • A loudspeaker is an electronic device that converts electrical signals into sound waves, but a microphone does the opposite – it captures them.
  • Loudspeakers typically use paper or plastic cones to move air and create sound waves by pushing on neighboring particles in open space; microphones use a thin diaphragm to vibrate in response to sound waves and create an electric current.
  • Loudspeakers are used for live performances, speeches, concerts, etc.; microphones are used more often than not with recording equipment.
  • A loudspeaker is typically found on stage during live events; mics can be located anywhere there is a need to capture sound.
  • Loudspeakers are typically installed in groups; mics can be used alone or as part of an installation.

Can A Speaker Be Used As A Microphone?

A loudspeaker can technically be used as a microphone, but it won’t work very well. This is because the speaker itself isn’t designed to capture sound waves in open space or convert them into an electric signal. The amount of signal they will produce will be minute.

It’s much more common to use a microphone for recording purposes, and they typically produce much better results.

Conclusion – Difference Between a Loudspeaker and a Microphone

Now that you know the difference between loudspeakers and microphones, you can make better decisions about what type of audio equipment is right for your business!
