Intro: Passive Cell Phone Speaker
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!
