Supersize your sound Pump up the volume on your phone with an easy-to-make speaker
Pump up the volume of the speaker on your phone
if you love listening to music, but the tiny speaker on your phone just doesn’t cut it, give it a boost with this low-tech solution. A simple plywood echo chamber does the trick. Slot your phone into one end and give it the deeper sound it deserves.
No power? No worries! You can still enjoy your music without the need for cords or charging, unlike a bluetooth speaker.
