Water speakers without the sound output?

Question

I'm not sure if I'm asking this in the right place here, so please forgive me if not. It's a bit of a strange one.

I have a set of water speakers, which I absolutely love, and I'd like to be able to see the water 'dancing' at night with no music. I know that it is possible to physically disconnect the speakers inside, but I'd like to be able to use them as speakers as well sometimes.

I was wondering if it would be possible to use a program like audacity to produce a sound output that cannot be detected by the human ear but still produces a voltage, or something like that. Any suggestions would be appreciated.

Solution

You just need to disconnect the speakers from the water part of the device. It is pretty simple and self explanatory. I was also able to find a Video on YouTube for it. Check it out here.

If they want to also hear some sound , a 4 way slide switch and a resister array (simpler than it sounds) could be mounted on the case. Adding some resistance would lower the total power getting to the speakers.

Thanks for this, I knew it could be done by physically changing the circuitry but I didn't really want to have to take them apart and I also wanted to be able to hear the sound when I wanted to, but from @Psycogeek's answer it looks like it's the only way so I'll just have to implement a switch

Thank you for your detailed answer. My main issue was that I wasn't actually sure on the technical details even though I knew about the physics of the sound. I knew I could produce sound of a frequency outside the human hearing range, but I didn't think about the limitations of the circuitry in the speakers... there was me thinking I was being clever.
