How to Make an Underwater Speaker


Many home audio companies claim development of their own superior underwater sound technology, alluding to the fundamental differences of underwater versus open-air acoustics. The quality of these speaker systems vary, but inevitably, they are all more expensive than standard above-water speakers. Luckily, if sound quality is not your top priority, you can build your own underwater speaker system fairly cheaply and easily using only a battery powered iPod speaker system and any plastic, waterproof container. Throw this contraption in your pool, bathtub, or take it with you swimming in and ocean or lake.

Things You'll Need

  • Battery-powered iPod speaker system
  • Super glue
  • Screwdriver
  • Water-proof plastic container
  • Unscrew the iPod speaker system so that you can completely remove the speaker cones. Do not cut or damage the wires. Portable iPod speaker systems are built in many different ways and it is important to use one with easily located screws. The speaker cones themselves are usually just positioned in place, though in some cases, you may need to unscrew them from the shell, as well.

  • Screw the speaker system back together so that it functions. The speaker cones should now by outside of the plastic frame itself but still connected by the speaker wire.

  • Apply glue to the outer edges of the speaker cones and attach them face down to the bottom of your waterproof container. Once the glue has dried, put the rest of the speaker system inside the container without placing it on the speaker cones themselves.

  • Plug in your iPod and place it in the container with the rest of the speaker system. Hit play, and close the latch on the container.
