What inspired me?

After only a few minutes of searching for some great ideas for phone holders, I noticed a substantial amount of acoustic sound amplifiers. This amplifies the volume of sound using a cone shaped piece directly under a speaker. I thought I would try it out.

What will you need?

-Wooden block (60mm by 40mm by 70mm)

-Jig saw, tenon saw, other wood working saws

-Files

-sander

-32mm speed bit

-13mm speed bit

-chisel or knife

Step 1: Step 1- the Notch

First, the notch. If you have a long piece of wood that you want to cut down, cut it to length after cutting the notch. This makes thinks a lot easier as you have a stronger grip. However, before I cut the notch, I had to mark it on. I decided upon the notch being 40mm away from the end to allow room for the amplifying cone. I made the notch 14mm wide. I then used the jig saw to cut these lines and cut out the notch.

Step 2: Step 2 - Cutting the Size

Second, I used the jig saw to cut the piece out. I cut a couple of millimetres from the end so I knew it was square and then cut a 45 degree line in the front of the holder. This angle was for design and styling purposes only and didn’t affect the practicality of the product as a phone holder.

Step 3: Step 3 - the Cone

I then used the orbital sander to sand all of the surfaces. This was a very time consuming process and very messy, so, I would advise anyone using the sanding process I chose to wear goggles and a mask as the tiny particles play havoc with you lungs and nose. Make sure you sand every bit and use a file to get rid of any saw lines from inside of the notch. Now its time to make the cone. This was the stage I wish I could change as it was very time consuming and not the most practical. First, I found the centre of the 45 degree side and marked this with an x. I then inserted the 32mm speed bit into my drill and drilled a 15mm depth in the centre. I then switched to the 16 and 13mm speed bit to get that effect. I used my dremel to clean it up but you won't have to, I just messed up a little bit and wanted to lightly sand it. I then used the 13mm speed bit to drill holes directly under the notch, so the sound from the speaker can go straight into the cone. Once all of that was done, I used a small chisel to just neaten up the holes in the notch and began to sand once again. I then decided to use some very dark stain to finish off the product.

Step 4: Finished
