Hello! I’m William, reporting from WLBCC Headquarters! Have you gotten tired of sharing your airpods? Do you want music for your whole squad to share? Fear not! Today, we’re going to make a speaker! The best thing about it? It actually amplifies your phone! This version is not that portable, but makes for great amplification!

A front view of the first speaker.

   What you’ll need to get started:

A 1-foot paper towel tube

Two plastic cups

First, cut a slim rectangle in the top of the paper towel tube. You should be able to slip the bottom of your phone into there. Now, cut holes into the sides of the plastic cups we made. You should be able to put the open sides of the tube into the hole in the cup. Now, hot glue the cups to the tube and your speaker is done! If it cannot stand, feel free to make a support beam in the back. Voila! Your speaker is done.

Here is the view of the support beam.



As well, you can make a more modest speaker. This one is much more portable but may not be as amplifying.

What you’ll need to get started:

A small cardboard box

Scissors; something to cut with

A pen; something to poke holes with

First, cut a thin rectangle on top of the box. The bottom of the phone should be able to slip right in without falling over. If not, don’t be afraid to make some support beams. Once the box is balanced with the phone inside, poke a hexagon of holes on each side (except the bottom). Make sure to also place a hole in the middle of each hole hexagon. Once that all works out,

 you should have a nice, portable speaker!

   These two speakers make for very handy devices, for being made of cardboard and plastic. Now, how does this all work? It’s actually surprisingly simple.

First, the speaker of the phone produces sound, that, in turn, bounces off of the cardboard tube and into the cup. The sound is very confined in the small cup, so it bundles all up, exits the cup, and produces amplified sound. As well, the shape of the cup gradually becomes wider as it goes upward, so if the sound goes from a confined space to a larger space, it would have greater space to spread out. This helps the process of amplification.

   I hope you have enjoyed this wonderfully enjoyable, not to mention scientific, project! Its considerably helpful for simple science and physics lessons, as well as a nice, casual amp! Thank you all for reading, and I will see you next month!
