IPhone Passive Speakers (powerless)

My 1st DIY project shared here using scrap materials
& left over materials from past projects i made,(this my 12th project now ).
I'ts my hobby & it's my  first time to share it here knowing that
there are lots of project that exist like this here..
But this one were all  made of scraps & excess materials only.. Just shared
here to make their iPhones plays music much better
without spending money...In this project i used my
old iPhone 4 (Jailbroken)...But this project applies
to any iPhone models (Jailbroken or not)..Of course
anybody knows that...
I enjoy listening to my old iPhone 4 now without
attaching it to my amplifier...

Steps:
1.Prepare the following materials shown in photos.
2.Cut the PVC for iPhone slot
according to your device width & thickness.
in this project i made it suitable for iPhone
with case protector.
3.Glue the welding goggle's Air Vents to PVC elbows.
4.Connect all together using glue,i use rubber cement for this project
5.This passive speaker can standalone without the help
of any iPhone stand.,but much better if you have one.,so you
can switch between Portrait & Landscape playing music & video.
6.It only cost me P 150.00 pesos  = $ 3.50 on currency exchange.
  that includes the  Black Spay ( Bosny no.39 )paint for finishing touches.
7.Hoping this project help any hobbyist looking for a
low cost passive speaker.Video link show the result of this project.
