Hey everyone!

Here's a new Instructables for a fun and quick project I put together, the passive cell phone speaker!

This project was made out of some pine boards I had and a new 16-piece hole saw kit I purchased.

So with out further ado, let's get started!

Step 1: Cutting Out the Wood Sections

The first step I took, was to take the pine boards over to my chop saw and cut out 8 - 6x6 inch pieces.

Step 2: Marking the Centers

Next, I took each of the 8 pieces and found and marked the center on each one of them.

Step 3: Cutting Out the Holes

Then, I took out my 16-piece hole saw kit and picked out eight different sized saws (going from larger to smaller) to cut holes in my pine pieces. I basically wanted to cut stair step holes, in order to sand down the sound funnel later on.

Step 4: Gluing Up the Pieces

After cutting and sorting out my pieces, I glued them all up to create the body of the speaker.

Step 5: One Glue Up Later...

Step 6: Sanding the Edges

Next, I took it and started to sand and smooth down the outside edges.

Step 7: Shaping the Speaker

Next, I started shaping the funnel for the speaker.

This part was a lot more work than I intended and took a few different methods before I finally got the shape down to what I wanted.

Step 8: Cutting Out the Sound Hole

The last piece that I needed to add was the section for the sound to travel through from the phone.

I created another funnel shape for the both the phone to sit into and for the sound to travel down into the speaker. I then glued it to the rest of the speaker, along with the back pine piece.
