DIY Phone Speaker

In a world where electricity is not always available, having access to simple and reliable technology can make a big difference. This is where my project, a DIY Off-the-Grid Speaker, comes in.

The project aims to create a functional speaker using affordable and accessible materials while reducing the need for conventional power sources. It demonstrates how creativity, basic electronics, and resourcefulness can be combined to create a useful device even in places where electricity may be limited or unavailable.

More than just a speaker, this project represents the idea that technology does not always have to be expensive or complicated. With determination and innovation, we can build practical solutions using what we have around us.

1. 2 paper cups
2. 1 craft tube
3. knife
4. marker
5. hot glue

Measure the width and depth of the music playing device you plan to use, like a cell phone. Using these dimensions, cut out a slot in the kraft tube to fit the phone. The speaker portion will need to fit into the tube when you’re finished.

Now it’s time to decorate! There’s no one way to do this! We painted our kraft tube with acrylic paint, added polka-dots with a circular sponge brush, and dip-dyed our cups by dunking them into a bowl of liquid watercolors. Get creative with your crafting techniques, this speaker could make a great accent to any room!

Hold your craft tube to the side of the cup near the bottom. Use a marker to trace the edge of the tube on the cup. Do this to both cups. Using a craft knife, cut out the holes you just traced. If needed, an adult should do any major cutting.

Insert the kraft tube into the holes in the both of cups. Angle the kraft tube so that the slot is pointing almost directly upright, but slightly backwards. When the kraft tube positioned in the cups, use hot glue to secure it in place.

Now insert the music device into the slot and crank up the tunes. You should hear music playing from the cups louder than the device can do on its own.
