Truly wooden speakers. They use a pair of transducers to vibrate a thin sheet of hard maple. They sound almost as nice as they look. Perfect for the office.

The transducers are: Dayton Audio DAEX25FHE-4 Framed High Efficiency 25mm Exciter 24W 4 Ohm, from Parts Express

Wow, didn’t even know this was possible. Do the sheets visibly vibrate? And do you think they audio quality will maintain or change with humidity/time? Nice work.

That’s super cool. I wasn’t even aware that this could be a thing. How thin is the vibrating sheet? I’m very impressed.

Instant favorite!
How does the kind, size and thikness of the wood used inflounce the sound?

Thank you guys for the warm response. As far as the technical details I’ll share what I can.
The “exciters” are “here

I’m driving them with this mini amp

They are fun. What I recommend is picking up a pair and playing with them. Just hold them against all sorts or materials. Thinner is louder. Stiffer has more bass. Both only up to point.

Mine are 6” x 9.75” and approx 1/16” thick.

I recommend checking out the video here for more info:

This is really cool! I have one question though – I can’t visibly see anything actually holding the thin sheet to what I’m guessing is the “exciter”? How is it staying put??

edit: nevermind – the exciter has a 3m adhesive already on it. I guess I should try the links first next time!

Too cool! And for no more than the parts cost, why not? Thanks for posting.

I think there were speakers like these back in the 80’s, can’t remember the brand name. The sound was directional, the volume could be cranked up and not seem that loud unless you were seated in the “sweet spot”. Wondering if these are similar?

Great project, nice result!

Do you know if adding a frame around the panel would alter the sound in a good way or bad?
I think this is a great design, now I’m thinking of some different metals to use.

NICE!
