Intro: Fabric-protected Cardboard Speaker
Do you want new professional looking speakers? Here you have stylish, easy and cheap speakers from recycled and remaining materials... and protected by fabric.
You can change size, fabric, shape,... pictures of your own work are welcome!
SAFETY ADVICE: This instructable uses sharp tools. Be careful using them. If you are not sure how to use, don't continue. For kids, it is mandatory adult supervision.
Step 1: Materials and Tools
You will need the following materials:
- Thick cardboard
- Decorated paper
- 2 or 4 screws with nut and washer
- 4 nails or wood stick
And the following tools:
- Pencil or marker
- Cutting mat
- Soldering iron and solder (if needed)
- Screwdriver or crescent wrench (for screws)
- Scissors and awl (not in picture)
Step 2: Cutting Cardboard
Cut three pieces of cardboard, as you can see in picture: one for the body and two for fabric protection.
Measures are calculated for a driver with 10 cm of external diameter and 0.8 cm of cardboard thickness. Adjust them to yours.
Notice that right section is narrow: it will overlap left section, so two layers of cardboard will hold the driver.
Fold by dotted lines. Help scoring with cutter and making pressure with scissors.
Next cut a circle in the centre of the left section and try the driver into. Once it works fine, mark the holes you need. Now mount the body and mark the circle and holes in the right section.
Step 3: Mounting Driver
Sold wire to driver if needed. Then glue both sections with circle and mount the driver with screws. Finally make a hole in back edge to take out wire.
Step 4: Making Fabric Frame
Now glue both square pieces, taking care to be in different cardboard direction: the frame will be strong. Make four holes, put the nails and attach to body to try.
Now put the fabric on (you can use any piece of fabric remaining), cut to fit size and then staple it, always starting from the middle to the corners.
If you are using a sheer sock (lycra) like me -that I think is very similar to professional speakers- be careful with nails and staples. Also, I recommend you to paint nails with a similar colour. Notice I'm using the sock as is, so two layers of fabric will be opaque.
SAFETY ADVICE: Do not use nails if children at home can catch up with. Change it by wood sticks or somehing soft that holds frame on speaker body.
Step 5: Decorating and Finishing
Finally, glue decorated paper. For best result, consider the top triangle the first part to glue. Let it dries and attach the fabric protection frame
Enjoy your original creation!
