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.

The best choice of music man 😍😍

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

i admire how much pride u put into this

That turned out really cool! Nice job Wildman.

Que padre felicidades

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

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

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

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.

凄く良いですね!!!

This is awesome!

frickin' awesome

Very cool and helpful

A like from Brazil!!!

Super cool video

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

Great song choice

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

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

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

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

It worked It worked It made my phone louder

Ben Howard, nice touch!

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. 👍

Need 1 for my XTE smartphone

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

Dude! You should sell these! That would be so cooool :) great vid by the way.

Cool

I wish I could do that haha

what was the title of the music that he played ?

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! :)

damn! its so very amazing :) (Y)

I would have also sanded down the channel inside the box as the roughness dampens the sound a bit, probably not noticeable though

Hola only spanic sory. medidas en español gracias

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

sounds better than PVC that's for sure

Thats legit Bro

You need a spindle sander!

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

1324?

Fuck yeah for only love

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?

"fun little lines".... BAAAAHAHAHAHAHA

Very cool men (y)

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

A holesaw would have made a lot cleaner cut.

Can u make me one

Got a little bit of kermit goin on there brother

If you have one big enough just use a hole saw

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.

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... :)

YOU DON'T NEED THAT MUCH GLUE!

I want one but i have a stupid iphone 3

1324 lol

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

Shut up and take my money !

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
