6 Speaker Facts: Explained

Let’s dive deep into each of these speaker facts, so you can learn more!

1. The First Speaker Was Invented To Amplify the Telephone

Did you know that the first speaker was not invented for listening to music but rather to amplify the telephone?

 Let’s take a quick walk through the pages of history and see how speakers slowly evolved into what we know today.

The traditional speaker we know today is the electric loudspeaker. Johann Phillip Reis invented the first iteration of this electric loudspeaker in 1861 and installed it on his telephone. The gadget could reproduce clear tones, but the speech got a bit muffled.

Approximately 15 years later, in 1876, the inventor of the telephone, Alexander Graham Bell, patented his version of the electric loudspeaker and incorporated it into his telephone. 

Bell’s speaker improved upon Reis’ invention by delivering clearer tones and intelligible speech.

Over 60 years later, in 1925, the dynamic speaker was invented by Edward W. Kellogg and Chester W. Rice. 

The dynamic speaker is the most common form of loudspeakers used today.


2. The Most Expensive Speakers Cost $4.7 Million

Do you have around 5 million dollars lying around, burning a hole in your pocket? 

Well, for that much, you can consider buying Hart Audio’s D&W Aural Pleasure to become the proud owner of the world’s most expensive speakers.

The creator of these speakers, David Hart, designed them to look like human ears. If you want two giant gold ears in your living room, there is nowhere else you’ll find them – that is, if you can find them.

There are only 105 pairs of Hart Audio D&W Aural Pleasure in the world. 

99 of these are made using bronze, priced at $62,800 each

Then we have 5, made using sterling silver which increases the price 5 fold to $313,900. And the final piece of the Hart Audio D&W Aural Pleasure is made using 18-carat gold, weighs in at 100kg, and comes with a mere price tag of $4.7 million. 


3. The World’s Smallest Speaker Is the Size of a Quarter

The INSIQ World’s Smallest Portable Bluetooth Speaker is the smallest speaker in the world. The INSIQ speaker measures a diameter of 1.2 inches (3 cm), slightly wider than an American quarter, and weighs 2.1 oz (60 g).

But how loud can these speakers get? Well, it’s loud enough to drown out my iPhone X at max volume. That’s pretty impressive given the small form factor.

Other than that, the device comes with Bluetooth 5.0 for easy wireless pairing. 

There’s also a dedicated button to help you take selfies. How cool is that!

I was also impressed with its battery backup. This tiny thing can offer up to 2 hours of continuous music playback! 

I would have never guessed you could get that much life out of such a small footprint.

Here’s an 8-min YouTube video from Unbox Therapy giving a quick rundown of these speakers:

4. Almost 200 Million Smart Speakers Were Sold in 2021

The smart speaker market is the newest and most innovative sector of the speaker world. 

Ever since companies like Google, Apple, and Amazon started producing these products, the smart speaker market steadily grew every year.

According to SP Global, worldwide shipments grew by about 12% in 2021. The projected smart speaker sales in 2021 were over 186 million units.

Additionally, the smart speaker market is still on a growth track. Statista.com reports market revenues to increase from $15.6 Billion in 2020 to $35.5 Billion in 2025

That’s a 225%+ increase in revenue over five years!

5. The Loudest Speaker in the World Goes Up to 188DB

The loudest speaker in the world is a 60-inch set of subwoofers designed by Richard Clark, Mark Eldridge, and David Navone. 

These 60-inch subwoofers are capable of producing sound up to 188 dB! That’s pretty loud! Especially when you consider that a Jetplane produces just 150dB during take-off, and that’s enough to rupture your eardrums. 

These speakers were never mass-produced for sale, so you’ll struggle to get your hands on them.

However, if you ever manage to come by these subwoofers, be sure to wear some hearing protection, or it can melt your brain!

6. You Can Make a DIY Speaker With Common Household Stuff

At its core, speakers are very simple devices. 

If you’re interested in building a speaker yourself, you can watch this awesome 5-min YouTube video on the subject:

Here’s a quick look at the different parts of a speaker:

  • Dust Cap
  • Cone (Surround)
  • Spider/Damper
  • Basket
  • Top Plate
  • Pole
  • Rear Plate
  • Magnet
  • Voice Coil


You can make objects 1-7 by recycling common household items like plastic bottles, paper, and cardboard. 

For the voice coil, you can make a small cylinder using recycled paper and then wrap it around copper wiring to prepare the coil.

And finally, for the magnets, I recommend getting these super strong Neodymium discs from Amazon.

This isn’t exactly going to produce the next quality speakers that you might want to install into your car.

I loved my car but was frustrated with my media system. So I upgraded my stereo, making silly wires and precarious phone mounts a thing of the past. The Apple Car Play stereo was so good I wanted to show more people how this could be done and truly upgrade their cars multimedia system! Founder StereoUpgrade.com
