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.
Step 9: Pre-staining
After it glued up, I took some Minwax Pre-Stain wood conditioner to prepare the speaker for the stain I would put on.
Step 10: Staining
Then after the pre-stain dried up, I added some Minwax 'Golden Oak' wood finish to add some color to the speaker and really help the grain pop.
Step 11: Turn It Up!
Voila, the speaker is complete!
This was a fun and quick project that I think turned out really well.
Let me know if you have any questions, and let me know what you think!
Be sure to watch the video on how this was made, and to hear the speaker in action:
