Default Something a little different: quick-and-easy iPod Horn

Hi guys,

Having seen someone's link to an iPod dock-horn, I figured I might as well see what the noise is about.

So I broke out the cardboard and masking tape (in typical scruffy teenager style), and made myself an exponential horn. Pictures attached. You get maybe 6-9dB gain out of mine, which is nice to have. Sounds reasonable enough - very good when you consider it's cost nothing.

Anyone else done something similar?

Chris

Great job Chris, the quick and dirty jobs are often the most rewarding.

Any plans to make a bigger one?

Fantastic! What did you use to calculate it? Do you feel it is optimal? Really cool.

Lovely Thanks for posting this. Small miracles like this made out of cardboard and tape keep our sense of wonder alive.

Hi guys, thanks for the encouragements.

In order:
Boscoe, no plans were followed. I simply set a compass to its widest radius and went from there: iPod width at one end, 6" across at the mouth. I pretty much made it up as I went along.

Thunk, cheers. I might be thinking about making a bigger one: upon hearing it, my sister asked if a bigger one would be louder. One way to find out.

Rjbond, there were no calculations here. Optimal? Probably not. It definitely works, though. The problem is that I have no idea of the characteristics of the iPod speaker, so Hornresp isn't an option (AFAIK - if someone wants to show me how it can work this out, I'd be happy to learn).

Dave, I'll see what I can do - just don't expect anything as neat as the plans on your 'site.

Kristleifur, thanks again for the encouragement. I was amazed at what this could do, just with the expanding horn section - when I made a proper cradle for the iPod, there was more improvement (I'd guess it was down to sealing the iPod to the horn).

I'll try to get plans done this weekend for those of you that might be thinking of making your own

Chris

Much better than my method of sticking the bottom of the phone between my fingers to use my hand as a horn. I know nothing about building horns but your method looks like a great starting point. Even if you just post the basics of what you built, that would help greatly. Thank you for sharing!
