Did you know that the best loudspeakers have a sensitivity rating of over 90 decibels?

If you’re like most of the world, you don’t know what 90 decibels sound like. For reference, 90 decibels is about the noise level of a lawnmower or a typical concert. 90 decibels is so loud that you need hearing protection!

The loudspeaker is a remarkable invention. How do these electric sound-making machines produce sound so loud that it can actually hurt our eardrums?

If you buy a speaker from an online store like 10speakers and you’re wondering how a loudspeaker works, you’ve come to the right place. Keep reading to find out.

What is a Loudspeaker?

Let’s start by clearing up a common misconception. A loudspeaker isn’t necessarily loud.

That’s right. A loudspeaker is just another term for a speaker. Radios, smartphones, and computers all have small loudspeakers with a relatively small range of sound.

A loudspeaker is basically just a machine that turns electrical signals into sound waves that travel through the air. It is distinct from headphones or earbuds, which send sound waves directly into your ears.

How Does a Loudspeaker Work?

Now that we know what a loudspeaker is, how does it actually work?

Let’s start by talking about how sound works. Sound travels through the air in the form of waves that move on different frequency levels. High-frequency sound has more waves, while low-frequency sound has fewer.

We measure frequency in something called hertz. The range of frequencies that the human ear can pick up goes from approximately 20 to 20,000 hertz.

Let’s say you connect a loudspeaker to your computer. When you play recorded music, you send an electrical signal to the loudspeaker. This signal contains information about the frequencies in the song.

The loudspeaker then takes that electrical signal and uses a device called a motor, or iron coil, to turn the signal into mechanical energy. The motor is what the speaker uses to vibrate what’s called a diaphragm.

The diaphragm is a thin sheet made of paper, fabric, plastic, or sometimes a metal cone. The motor vibrates the diaphragm so that it can produce sound waves that correspond to the music’s electrical signal.

What If My Loudspeaker Breaks?

There are a lot of moving parts that make up your loudspeaker. If one of those parts breaks, then you won’t be able to use your loudspeaker anymore.

But now that you know how a loudspeaker works, you can look for replacement parts. Is the diaphragm broken? Order a new diaphragm. Did something happen to the coil? You can replace that too.

You can get replacement parts from your local music store, or from online suppliers like PRV Audio Brazil. If you aren’t feeling handy, you could always just replace the loudspeaker entirely.

Now You Know

They say knowledge is power, and now that you know how a loudspeaker works, you can put that knowledge to good use—whether that means entertaining your friends or fixing your own loudspeaker.
