Creating a mini JBL speaker box using cardboard is an exciting and educational project for school. It teaches students about sound systems, engineering, and creativity, while using simple, affordable materials. In this guide, you will learn how to make a working mini JBL-like speaker box at home using cardboard and a few electronic components.
Materials Needed for Mini JBL Box
- Thick cardboard sheets
- A small Bluetooth speaker module (or a mini amplifier board and speaker)
- 3.7V rechargeable battery (or use the battery from an old phone)
- Hot glue gun and glue sticks
- Scissors or a craft knife
- Ruler and pencil
- Colored paper or paints for decoration
- Wire, soldering iron (optional for better connections)
- Double-sided tape
- USB charging module (optional)
- Small pieces of plastic or transparent sheet for logo display (optional)
Step-by-Step Guide:
Design the Box
Start by sketching the design of your mini JBL box. Measure your Bluetooth speaker module and speakers carefully. Based on their size, draw a simple box template on the cardboard. A typical mini speaker might be about 10 cm wide, 5 cm tall, and 5 cm deep. Make sure to allow space for the battery and wiring.
Cut the Cardboard
Using your scissors or a craft knife, carefully cut out the cardboard according to your design. You will need pieces for the front, back, sides, top, and bottom of the box. Be precise so the box fits together snugly.
Create the Speaker Holes
On the front piece of the box, mark and cut out holes for the speakers. These should be just slightly smaller than the diameter of the speakers so they fit securely. You can also make a small hole at the back or side for the charging port if you are adding one.
Assemble the Box
Use a hot glue gun to attach the sides of the box together. First, glue the bottom to the back and sides, then attach the top and front. Leave the front panel loose for now, so you can easily insert the speaker and electronics later.
Install the Electronics
Place the Bluetooth speaker module and the speakers inside the box. Use hot glue or double-sided tape to secure them in place. Connect the speakers to the module. If needed, solder the wires to ensure strong connections. Connect the battery to the module and carefully place it inside the box, securing it with tape or glue.
Test the Setup
Before sealing the box, test your speaker setup. Turn on the Bluetooth module, pair it with a phone, and play some music to check if the sound works properly. If there are issues, recheck the wiring and battery connection.
Seal the Box
Once everything is working properly, glue the front panel to the box. Make sure all the components are well-fitted inside and that there are no loose parts. Press the box firmly while the glue dries.
Add Finishing Touches
Now it’s time to decorate! Use colored paper, paint, or markers to make your mini JBL box look attractive. You can print a small JBL logo and paste it on the front. If you have a transparent sheet, you can cut it into the shape of the logo and glue it on for a more professional look.
Conclusion:
Making a mini JBL box setup using cardboard is a fun, hands-on school project that combines creativity, basic electronics, and craftsmanship. It’s a great way to recycle old electronics and learn how speakers work. Plus, when you’re done, you’ll have a cool custom Bluetooth speaker to show off to your friends and teachers.
