How to make a Acoustic iPhone Amplifier

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. 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.

I am glad your design worked well for your needs. Here is some things you can do to improve the sound in your next build that would give you even better sound. In your design, the audio feeds to the bottom of circular hole through a wide channel that makes a 90 degree bend into the circle, and then bounces off the walls in the circular hole several times until eventually all the energy in the waves leave the hole. The biggest issue in that design is that it encourages multi path propagation of the sounds waves that result in some parts of a wave arriving at your ear sooner then other parts of the same wave, This means the audio is slightly distorted To improve the audio quality with fewer multi path modes, start with a narrow channel from your phone that gently tapers strait into a rectangular hole that feed the audio out with no bends. When looking down at your project, the bottom of the rectangular hole should be rounded so as to bounce the waves out immediately rather than bounce around several times on the walls of the hole. Less bouncing around also means less energy is absorbed into and dissipated inside your audio director, and more energy gets to the listeners ears in sync (makes it appear even louder) rather than spread out over time because of the bouncing around.

Very cool and helpful

[@WildmanDesignCo]

Thank you.

[@northernwrx]

great job man! i love the plans, thinking of doing it with a smaller opening going from the phone to the circular holes. thoughts?

[@WildmanDesignCo]

+Jamie Fitzpatrick I think that should be fine. Not sure what it would do to the sound.

[@haydendavis382]

Am i the only one who notices his order of the boards? hahaha 1,3,2,4

[@zedekiah04]

"I numbered these so they are in order" 1,3,2 and 4 XD

[@WildmanDesignCo]

+zack23048860 gaming We all make mistakes right?

[@zedekiah04]

WildmanProject oh... i thought it was a joke.... nice vid btw XD

[@WildmanDesignCo]

+zack23048860 gaming Nah, I screwed up, lol. Thanks glad you liked it.

[@zedekiah04]

WildmanProject =D

[@kreynolds1123]

IPhone, I crap... otherwise, way to go. But, there is no amplification. That is, you are not amplifying the amount of energy in the sound coming from our phone. Rather, you are gaining directionality. Phones put their speaker on the back, or in your case, the bottom, thus sending sound away from your ears while you watch youtube videos. Your build redirects and focuses the sound to the listener.

[@WildmanDesignCo]

Thanks for your opinion. Interesting to look at it that way. Just having fun making stuff, didn't put much thought into the science behind it.

[@sonodrome]

@Keith Reynolds I beg to differ: "The horn can be thought of as an "acoustic transformer" that provides impedance matching between the relatively dense diaphragm material and the less-dense air. The result is greater acoustic output power from a given driver." - Wiki

[@Stjarna_Svinsdottir]

If you want to vastly simplify your life, cut the hole on piece 3 with a hole saw (preferably in a drill press), glue on piece two, rough out the hole, and finish with a laminate trim bit in the router, and repeat with piece 1. With denser wood than pine you might not have to do more than finish sanding, assuming you're using sharp carbide router tooling.

[@WildmanDesignCo]

Siouxsin M I am making them now to sell, so I have it down pretty good. I cut the circles out with a jig saw, two half circle cuts each hole. Glue the three pieces together, then finish sand with a orbital spindle sander.

[@alfredosantiago3168]

Great work amma see if i make one for me i build speakers with car radios

[@anthonyhewitt9397]

see I love this kind of stuff as a musician that does alot of d.i.y. when it comes to nik naks. and improving your instraments, hate having to buy everything especially when doing it yourself makes it more satisfying, educational, and cheaper and even somtimes work better

[@taraara5749]

At 0:32 you are showing us how to mark the wood with numbers so we don`t mix it up. I thought this really funny because you have marked the pieces of woods with numbers 1-3-2-4 while saying 1-2-3-4... ;) anywayz It is a good video of a nice project, and of course you fucked up the numbers so we wouldn`t... :)

[@WildmanDesignCo]

Alright you caught me. I was waiting for someone to say something. I noticed it when I was editing the video....opps.

[@xsjadoninja]

Fuck yeah for only love

[@jarboe1000]

Ben Howard, great musician, and it was an awesome project too :P

[@WildmanDesignCo]

Winner!! Love me some Ben Howard.

[@abelmartinez8662]

Hola only spanic sory. medidas en español gracias

[@sidmalicious]

Horn would've been easier, cost less, would have used a bit of brains to master the acoustical physics, but it would have also been as portable as one of those useless iPhone cases. I remember before all these geniuses even thought to amplify a cellphone I refolded a cardboard box on a jobsite and had music and speakerphone conversations in tight spaces of buildings where we couldn't even get a small boom box in. I should become an Etsy entrepreneur and quit my "useless" day job to join the liberal scum... :D

[@badandy2246]

Great choice in music to test it! Love Ben Howard! Nice job

[@WildmanDesignCo]

Thanks Andrew. Big fan of Ben Howard. found out about him on KZbin....wired.

[@tommitchell1570]

I am using a similar design to yours for GCSE and i would like to know how to make it louder. :) :)

[@dangeroustoys5668]

neat idea, im thinking if the channel was a bit straighter and smoothed out it would sound even better. in this case , wood is more denser then pvc , makes it sound richer. 👍

[@EarnieMercerDungeonstiles]

Put some felt in the phone slot might tighten up for ya. Nice job

[@felcastt]

great job bro!! i made it and it works perfectly

[@Hamosaurus]

very good! vou fazer uma caixa dessas para meu Samsung ok thanks.

[@FoxThaStoner]

I like this bro. Probably could do this better n easier if I was still in HS. That's somethin

[@WildmanDesignCo]

+Mista Fox Thanks!

[@primozmiklic1366]

Shut up and take my money !

[@WildmanDesignCo]

I am guessing you would buy one to?

[@quicksilver1263]

what was the title of the music that he played ?

[@taroyamada3249]

It worked It worked It made my phone louder

[@georgenettlesjr1466]

Need 1 for my XTE smartphone

[@jackmartin7140]

The best choice of music man 😍😍

[@podoz]

"fun little lines".... BAAAAHAHAHAHAHA

[@marvinmann2711]

A holesaw would have made a lot cleaner cut.

[@WildmanDesignCo]

Sure, but you still would have to sand it after gluing all three together.

[@marvinmann2711]

@@WildmanDesignCo You are correct. But I find using a jigsaw for anything other than straight cuts (regardless of how slow I go) is a pain the butt. I prefer the holesaw for three reasons. 1) Faster cuts 2) Cleaner cuts 3) I'm not as likely to get angry.

[@redping]

That turned out really cool! Nice job Wildman.

[@WildmanDesignCo]

Thanks Amy!

[@MsAlaskanGirl907]

This is really impressive- I don't think I would have ever thought of doing this! Do you think you could make a list of all the tools you used? Thanks! :)

[@WildmanDesignCo]

Yeah sure, here is the list: Miter Saw - cut the pieces of wood to length Router - to cut the groove for the sound and round over the edge of the circle Jig Saw - Cut out the circle Belt Sander - make it nice and smooth Dremel Tool - clean up the inside of the circle

[@MsAlaskanGirl907]

WildmanProject Thank you!!

[@werleylima859]

A like from Brazil!!!

[@mikeyshelton6771]

I wish I could do that haha

[@LilQuickScopeBear626]

Nice im going to follow you u make some nice things bro

[@WildmanDesignCo]

Sounds good. Send me some pictures!

[@bassim_77Wjets]

Can you make Acoustic Amplifier for Samsung Galaxy Note 3 with hidden charger inside?

[@WildmanDesignCo]

Are you asking me to physically make one? If so, I don't have need for one and I dont have a Note 3. I am sure it can be done though. The charger part might be a little tricky.

[@bassim_77Wjets]

All I think of was to make sure that width is wider to fit perfectly with the otterbox installed on the phone. :)

[@bassim_77Wjets]

By the way, you did a great job on the amplifier. :)

[@WildmanDesignCo]

***** Yes you would make the slot the phone sits wider to fit the Note 3.

[@mrrohrig2]

1324 lol

[@migzgarcia3095]

it was to cover the sketch :3

[@wdbaudio]

This is awesome!

[@WildmanDesignCo]

I thought so to.

[@kukalkan]

Que padre felicidades

[@rodneykupcs2305]

Great song choice

[@Brandon-zn1qd]

If you have one big enough just use a hole saw

[@WildmanDesignCo]

Brandon Earles I didnt, used the tools that I had.

[@pohshimin8564]

what wood did you use? :) doing a research on music and wood

[@WildmanDesignCo]

poh shimin On this one I used pine. I am sure there is a better species of wood for this.

[@dimitheodoro]

WildmanProject i make also those boxes..i used Cypress and had amazing result!!!

[@greenmarine5]

sounds better than PVC that's for sure

[@WildmanDesignCo]

Thanks!

[@theonewholearns2711]

hey wildman, i'm gonna use this and make instructions out of this on how to make a passive amplifier (year nine and making amplifiers), but i'm not gonna do this, i have my own plan, pretty simple and might not work, unfortunately, since it's got about 4 layers, layer 2 and 3 will be hollowed out (layer 3 will be slightly different from layer 2 so that it can hold the phone inside), the top is going to be rounded, also we had to make another thing, forgto what they called it, had to make what i was going to make at home, with anything i had at hand, and made it out of cardboard and celetape or something, and the top was rounded, so i had to work with 2 times pi times r, needed my dad to help. can you help me, have trouble remembering, is pi 3.14?

[@theonewholearns2711]

+why on earth would anybody well, maybe not use you're video for intructions, but i will recommend it in the link, because you have to leave a link to the video

[@WildmanDesignCo]

+why on earth would anybody That works!

[@kickboxer99]

+why on earth would anybody hey pawel. its fynn from school. don't know how I found you on the web lol. maybe check out my videos.

[@theonewholearns2711]

kick boxer99 might delete this post, change my name, profile pic, and stuff, and this'd never have happened. are you doing last minute DT homework?

[@kickboxer99]

[@pinterelectric]

Nice project but, for less than the price of the wood, you can get a little Bluetooth speaker

[@WildmanDesignCo]

Jeff Pinter where can you get a Bluetooth speaker for $2.50?

[@MarkTillotson]

And indeed one with an everlasting battery at that!
