The iPhone SoundFrame was created from a need to watch videos in landscape mode on the iPhone. All iDevices project sound out of the side mounted speaker in a direction at right angles to your ears. You tend to hear more ambient noise than sound from the speaker. There are solutions on the market and other Instructables that detail creation of a passive amplifier for the iPhone to overcome this, but none of them focus on the landscape mode of operation and my personal preference for the sound to be projected from the middle of the device, rather than the right side. Watching videos with a person speaking while standing on the left of the screen and having the sound projecting out of the right is just wrong!

I experimented with a simple layered construction foam model (building on the fly with nothing more than scissors and glue) and was surprised at how effectively the sound could be “bent”. I am no acoustics expert so can’t help you out with the science other than to confirm that sound reflects down the channel and out of the front of the frame.  This rough prototype showed that the concept was feasible. The second consideration was the aesthetics – the balance between form and function. Using a 3D Modeling tool allowed multiple iterations before arriving at a final solution without wasting materials and time. An important design aspect was what to do with the SoundFrame when not in use. Designing the frame to have a secondary function as a picture frame provides utility when the iPhone is not present. It also makes a great holder for your iPhone at night if you use your phone as an alarm clock.
I also made a SoundFrame for the iTouch. For this unit I included a slot in the side for the charging cable and inlaid a thin piece of wood to block the top surface of the sound channel to increase volume even more.

Step 1: Setting the Scene - the Process

The iSoundFrame was created using Alibre Design Personal Edition software for the 3D modelling, followed by CamBam for converting the design to g-code, which is interpreted by Mach3 Machine Controller software to cut the SoundFrame out of a block of plywood using a CNC Router. The CNC Router was designed and built by me ( construction details here : http://dlsprojects.blogspot.com/ )so it would make little sense to build this tool and then have to resort to hand tools every time I wanted to prototype something. But, given that a CNC Router is not typically available in your home workshop (though through places like TechShop and other hacker spaces, access to these precise and capable machines is easily possible), I will also detail a manual technique using layered construction at the end of this instructable. To do this I used 123D Make Software from Autodesk to slice the model into layers that you can cut out using hand tools. The iPhone SoundFrame  is then constructed by gluing the layers together. But first you are going to have to suffer through the CNC method, so here goes!
I would really like to make this sound frame by hand using the stacked slices method and a jig saw. You mention importing the soundbox.stl file into 123D Make but I dont see that file anywhere on here. Could you possibly upload it? In the mean while I will try to model my phone!
I uploaded the file to step 10. You will need to remove the .pdf from the file to get Soundbox.stl <br> <br>The file is not a PDF file - I do this to avoid complaints from the Iinstructables file uploader
&gt;hand to forehead&lt; Thank you!
Ok so who doesn't have a laser cutter?
Awesome! I have to try one. Maybe I'll leave an opening for charger cable.
Thanks - one of the later steps shows a version I made for the iTouch. For this one I cut the slot in the side for the charger cable. The wood gets very thin on the side of the sound channel so you have to work carefully!
Awesome idea!, my current phone stand is a business card holder. I will attempt one of these it will be a big improvement. <br>
