The paper cones of most speakers are very flimsy and not suited for being submerged in water. Even marine speakers available on the market today are meant to be placed beside a pool, not in it. So if you would like to waterproof your speakers, you will need to seal them so that water cannot get in. This can be done with some discarded pieces of plastic you may have lying around your home.

Make an outline of the speakers on the front of the plastic container by placing the speakers flat on the surface of the front of the plastic container and tracing an outline of it using a black marker.
Cut the two outlines you just made with a dremel cutting tool.
Cut two round patterns from the rubber gloves that are slightly bigger than the two holes you made previously. These will serve as the membrane through which sound will travel while keeping water from entering the speaker cones.
Epoxy the inside edges of the holes of the container and place the two round rubber glove patterns into the holes from the inside. They should be cut slightly larger than the holes, so they should be placed on the inside of the container. Let the epoxy set and dry.
Seal the outside edges of the rubber membrane with silicone. This procedure should waterproof the edges where the rubber glove pattern makes contact with the plastic container. Do not do anything afterward to let the silicone dry.
Install the speakers in the holes. Secure the fit by using epoxy on the edges of the speakers. Install the electronics board by placing it inside the plastic container. Connect the wires from the electronics board to the speakers using solder and cover it with electrical tape.
Place a 9-volt battery clip inside the container. Solder the battery clip with the wires of the electronics board. Cover the soldered part with electrical tape.
Place magnets on the battery clip and on the inside of the container to hold it in place.
Hot glue all the dangling wires and the electronics board onto one side of the container. This will ensure the internal parts of the waterproof speaker do not move around and that the wires will not get tangled or detached. Install the 9-volt battery into the battery clip.
Tape the plastic mesh onto the speakers. Put your music device (MP3 player) into the container and plug it into the input jack of the speaker. Turn the speaker on by pressing the "On" switch on the electronics board. Close the lid.
Test your waterproof speaker by letting it float on the water.
Tips and warnings
- Do not submerge these speakers in water. Although they will be water resistant, they may not be 100 per cent waterproof.
