Building a Passive Speaker for Your Phone

This is a very easy how to. You can do it for nearly every type of phone with a speaker.
You don´t need any electronics or solder iron.
It works and you can fill the room with sound of your mobile!

You need some copper plumbing parts.
A piece of wood for the base plate.
A paper funnel.
Some glue for paper and metal.
Some two component clay.
A brass screw

Cut the end of the paper funnel and glue the copper part on it.
Use wax stain to colour it. Wax stain gives the paper a wooden finish.
I stained it two times and I used a shoe brush to polish it.

Use metal glue to glue the pipes together in that form you like.
For the cradle I used a piece of aluminium.
I drilled a hole in the aluminium profile so the sound of the phone will go trough the hole. See picture 2 and 4.
I flattened a piece of copper pipe so that it fits inside the Aluminium profile.
Than I used two component clay to fasten it.
At least I drilled a hole in the tube for fasten it on the stand.

I the glue is hardened you can mount it one the piece of wood you have chosen as the base plate.
Attach the phone and enjoy the music. :-)
