If you love listening to music but don’t have a portable speaker handy, don’t worry! You can easily amplify your iPhone’s sound using simple household items.
This fun and creative DIY project requires minimal materials and effort, yet it significantly enhances your phone’s audio output. Follow these step-by-step instructions to create a stylish and effective DIY iPhone speaker.
Materials You’ll Need:
- Cardboard tube (such as a wrapping paper or paper towel roll)
- Two plastic cups
- X-acto knife or sharp scissors
- Contact paper, duct tape, or wrapping paper (for decoration, optional)
- Hot glue gun and glue sticks
- Gold spray paint (optional for aesthetics)
Step 1: Prepare the Cardboard Tube

Cut the cardboard tube to approximately 8 inches in length.
If desired, cover the tube with decorative contact paper, duct tape, or wrapping paper for a polished look.
Smooth out any air bubbles to ensure a clean finish.
Step 2: Cut a Slot for Your Phone
Place your phone on top of the tube and mark the width of your device with a pencil.
Using an X-acto knife, carefully cut out a rectangular slot where your phone will rest. Make sure the slot is wide enough for your phone to fit snugly but not too loose.
Smooth out the edges with sandpaper or scissors if needed.
Step 3: Create the Speaker Cups

Take one plastic cup and trace the circumference of the cardboard tube onto its side using a scrap piece of paper.
Cut out the traced circle using sharp scissors or an X-acto knife.
Repeat the process with the second plastic cup.
(Optional) Spray paint the cups gold or any color of your choice for a stylish finish. Allow them to dry completely.
Step 4: Assemble the Speaker

Insert one end of the cardboard tube into the hole in one of the plastic cups.
Secure the connection with a hot glue gun.
Repeat the process on the other end of the tube with the second plastic cup.
Allow the glue to dry completely to ensure stability.
Step 5: Test Your DIY Speaker

Place your iPhone into the slot you cut in the cardboard tube.
Play some music and enjoy the amplified sound!
Experiment with different placements to find the best acoustics.
