Powerful underwater speaker

[LEO1982]

I think it's relatively easy to do. If you put a power supply, a vibration speaker of suitable power, and an economical class D amplifier in a reliable sealed case, all you have to do is connect it via a sealed connector to the DRS-100. Perhaps you could then add a volume control.
I assume that there are many similar designs, for example this one: Using a vibration speaker allows you to significantly increase the volume or reduce power consumption, increase battery life.

Great! We have successfully connected the underwater speaker to the DRS-100! This speaker really helped solve a big problem! Next step is to shoot some underwater martial arts style short films in our underwater production center! Thank you again for your solution! Cheers!

This is a cool project.
I just got a pressure cooker as well.

But what do you do about the pressure release holes in the lid? Do you block them?

We unscrewed the standard pressure relief valves (emergency and working) and plugged these holes with stainless steel bolts with O-rings.

If there is no suitable screw to replace the original one, you can try to use a metal gasket to replace the spring. A rubber gasket can be added on top of the gasket to increase the sealing performance. The specific implementation plan should be adjusted according to the structure of the pressure relief valve. I hope it can help you.

Please keep your music noise pollution out of the tranquil water.

I admit it. I'm an old man and I'm set in my ways. I'll try new stuff only if can see a benefit in trying it. So when it comes to underwater speakers, I have to ask why? Where is the benefit?

I worked with a group in Norther Florida who had a super high tech signaling device that worked like a charm. It never failed, never required maintenance, was probably heard by submarines a thousand miles away and did not require batteries. It was a steel pipe hanging in the water with a hammer hanging next to it. We all had codes written down on slates. Two bongs..squall coming...three bongs....seas rising....four bongs...emergency surface now...etc.

So what can a speaker do that that old steel pipe could not do? Play music? Forward calls from the wife? No thanks. I'll pass. I could see a use in the pool during training but on real dives? Nope! I like the sound of the sea from underneath. If I wanted to listen to music, I'd sit in the car. I would not be surprised if the underwater speaker had continuous issues with people cutting the cord!

Well thank god for Bluetooth then.
I plant to connect my phone in a diving case with bluetooth to a vibration speaker inside the pressure pot.

The music will be a mix of Britney and Shakira. I heard it helps the reef.

No, for Shakira, just the video, no audio.

Pass on all things Brittney (at least the nowadays Brittney).

How much pipe was submerged? What was the approximate length, diameter, and wall thickness?
