from your cellphone with other people, but the sound...
just to LOW!!
The revolutionary WALLET SIZED Whirlwind Speaker
and stand will come to the rescue!"
He he, sorry I just couldn't help myself :D
Joke aside, sometimes I have found myself sharing a video with family and friends, and yes, sometimes the volume is just a bit low.
So, I started to think.
Could I come up with some kind of speaker that could fit in my pocket?
Better yet, in my wallet?
Well, it turned out that I could.
How does it work?
The idea is to redirect sound to you (the viewer) which helps with the volume, but the horn itself will increase the overall acoustic efficiency of the iPhone.
Remember, it's a passive component and does not amplify the sound from the driving element as such, but rather improves the coupling efficiency between the speaker and the air.
Horns used to be called "acoustic transformers" because they help match the impedance between the speaker diaphragm and the air. The result is greater acoustic output from the speaker.
And how does it sound?
Well, in "get you wife and kids to listen to it" tests, it makes the sound out of my iPhone seem twice as loud and deeper.
So, If you use it in a noisy place (like a restaurant) you will be able to hear you video, but without getting the next table to complain.
Now, I'm including the "bone white" version of the Whirlwind, so that you can make your own versions (a steampunk version would look wicked)
Note: It's trivial to modify the horn base to fit any cell, not just the iPhone.
