I wanted to make something that could allow people to listen to their iPod with a little more style than a pair of plastic speakers. I used maple and mahogany wood—both work well as its stiff and doesn’t vibrate.

Acoustically sealed, this speaker provides ample listening possibilities without needing to bring extra batteries or worrying about finding a plug to put it in. All you need i your charged iPod, iPhone, Walkman or even a Zune! It uses a standard headphone jack for input.

Want to listen to Rachmaninoff while sipping your morning cafe au lait in your Pied-à-terre? This speaker can handle that.

Want to relax to some Joni Mitchell while painting or sewing? This speaker can handle that.

Want to blast some tunes from Metallica, Black Sabbath or Iron Maiden? This speak can’t handle that. Since it’s not a powered speaker it’s limited in what it can handle. It’s never going to get too loud or fill more than a small or medium size room with music. I find that you need to have the volume at a minimum of halfway to hear it. Typically you’d have it set to 80-90% max for general listening.

Try setting your iPod or iPhone’s equalizer to ‘Small Speakers’ and it works wonderfully. Some may anthropomorphise this speaker and think it’s staring at you. Maybe it is.

Another awesome project!

Speakers have a spec known as sensitivity (or, incorrectly, as efficiency) that indicates how many Decibels the speaker will produce when given one watt of input, and measured on-axis from (IIRC) one meter away.

For an application like this (NON-powered), pay particular attention to getting a good quality speaker with a HIGH sensitivity spec.

thanks for the info neil, i’m aware of sensitivity specs, but just wanted to know where the source was for these type so i could see if it’s even worth it…

I don’t know that high sensitivity automatically equates to high cost.

I think you could find higher and lower sensitivity speakers at almost any price range, so … I was just thinking that it was a good factor to be aware of when evaluating drivers in your price range.

Taking a /quick/ look, I see, for example, that there are LOTS of full-range drivers with SPL (Sound Pressure Level) ratings of 87 (dB/W/M), and that there are a good handful with an SPL of 90+ dB

That difference … is pretty huge, functionally. Even Radio Shack offers what /appear/ to be decent full-range drivers with an SPL rating of 91.

Again … big difference in volume for a low-powered application.

I think, for me, I’d shoot for a minimum of 90dB.

You could probably also buy a fairly inexpensive in-line amplifier that would let you drown out the Unisaw, if you so desired ;-)

Thanks for all the nice comments. There is certainly an art to speaker design—it’s not a trivial thing to do (and I’m not implying I have it perfect either!). To make it easier there’s a lot of places that have calculators to help aid you in the process. I used these for my project:

I’m sure there’s others too.

Thanks!
