Acoustic IPhone Amplifier

About: I have a little DIY YouTube channel. My channel will feature DIY project that I do around my house. Everything from making a twin bed for my daughter to working outside in the backyard. I hope you will stick...

I came across this Acoustic iPhone Amplifier on Pinterest and had to make one. The awesome part is, no power required, just 4 pieces of wood glued together. I was surprised on how well it amplified the sound. I did this all for free, didn't have to but anything. I used materials that I already had in my garage. This would be great to use outside, camping, etc. Also you can adapt this to any phone, just change the measurements for the phone slot to fit your phone.
If I had to make this again, I would find a better way to cut out the three circles. Probably make some short of jig for my router. After I glued the three pieces together, it took a little bit of time to sand and make the circle(speaker) smooth. But in the end, it turned out great. I was very surprised how well it amplified the sound. Pretty amazing what 4 pieces of wood glued can do.

    ever use a non-electric megaphone? this is the same concept. it doesn't actually amplify the sound it just redirects it in a specific direction. instead of the speaker trying to project sound 360 degrees around the phone the "amplifier" focuses the sound in a certain direction. something like this should work great in my kitchen! GREAT INSTRUCTABLE!

    Nifty. you could probably find a hole saw that size, but jig saw works too. unless you've got a scroll saw hidden away somewhere. that'd be the best.

    Very nice work! I could imagine reducing the thickness of the back piece would even increase the resonance similar to a guitar case.
