Listening to music on a phone speaker is just awful. A speaker is good, but let's shoot for great! I will show you how to modify a "Hamburger" speaker into a device that will rock the house!
Step 1: Materials
For this, I used an old rechargeable speaker and a small tube.
Step 2: Trace the Speaker
Trace the outline of the speaker on the bottom of the tube.
Step 3: Cut It Out!
Now, we just have to cut out the circle, and secure the speaker in place! Use something that will secure it well. Tape is fine, but hot glue will always work best (in my opinion)
Step 4: Done!
You have successfully made an awesome speaker! Congrats!
