Hello all, I have an interesting personal project that I am hoping to work on, I just need some guidance as to how to go about it.

Has everyone seen those really crappy water speakers that Spencer's gifts sells? Well, I really like the idea of the light/water show incorporated into the speaker and I really want to try and take this idea to the next level.

Here are the speakers that Spencer's sells:

Now I want these speakers pretty big. Enough to fill my small house with some booming bass for a party. I want them to be the centerpiece of the room when it comes party time.
Big sound and a big light show, get my picture?

I am currently working at the engineering workshop at Penn State University and have access to most if not all the tools that I would need. My boss said that he thought I should run a rubber membrane over the drivers to separate the water from the speaker, but I'm not sure that it would give the bounce of the water that I would want.

Any ideas on where to start or how to go about it would be most helpful.

Thanks, Alex

I am stuck watching these things. What a killer thing to miniaturize. I hope you can figure this out.

It seems like the water feature is entirely separate from the drivers, so you don't have to worry about waterproofing the speakers. You'll probably end up with a normal speaker on bottom, and simultaneously feed the audio signal to a microcontroller to control the water jets in a separate enclosure on top.

Sounds Good to Me... keeping track of my audio projects.

Plus, being a teen in the 70's, the simple mentioning of Spencer's Gifts, just makes me smile smile.gif

Lol - I was writing an almost identical response when I saw yours come in! Totally agree, in order to shift the volume of water I think Hick's planning, will require something more heavy-duty than a speaker diaphragm.

I couldn't see how well this was happening from the video, but having the water's behavior closely correlate to audio frequency would be cool. I would investigate some kind of piston arrangement (powered by linear actuators?) to shift the water - using a microcontroller to control amplitude and 'attack'. I've seen threads where the color of background lighting is controlled by what's playing, so it wouldn't take much to emulate this capability.

Good luck with the project - Bellagio beware!

Exactly the type of reply I was looking for. Thanks guys, I'll look into the microcontroller and piston idea. Sounds great to me though. I'll keep the thread updated on my progress.

I know you're not looking at "dancing fountains" but here are a few links I found that might have ideas that could be adapted to fit your project:

Those are awesome! I'll definitely think about how to incorporate something like that. Thanks for the links!

Maybe use some marine audio speakers. Have them facing up and pour water onto the cone.

That might work but I feel like the water might just muffle the sound a good amount.

That's why you use a second forward facing speaker. You could also use a passive radiator with water.

Not sure water on top of a cone is all that interesting. But oobleck + UV dye + UV lighting on top of a second driver might be fun.
e.g. http://www.youtube.com/watch?v=3zoTKXXNQIU
or http://www.youtube.com/watch?v=7v0c0Al5X0g
