Building a passive speaker for your phone

This is a very easy how to. You can do it for nearly every type of phone with a speaker.
You don´t need any electronics or solder iron.
It works and you can fill the room with sound of your mobile!

Step 1: What you need

You need some copper plumbing parts.
A piece of wood for the base plate.
A paper funnel.
Some glue for paper and metal.
Some two component clay.
A brass screw

Horatius,
Here are the changes that I made to your instructable for my version:
The iPhone cradle I made of wood. I tried metal at first, and found that I didn't have the right tools to cut the somewhat precise hole for the copper tubing. I ended up cutting some 3/16" Luan plywood into pieces to glue together. First assemble the entire cradle - THEN mark, drill, and shape the hole. A Dremel tool and side-cutting drill bits work very well for those precise adjustments you may want to make. Also, I felt that it may be good to have the cradle in a material which is easier to remove/reposition, in the event that the speaker on the iPhone moves positions in future models. I did stain, and apply a couple layers of a clear polyurethane to protect it.

I used brass #8/32 screws to adhere the copper tubing to the base. On the underside of the wood base I recessed the holes with a spade drill bit so the heads of the screws would not be an issue. I used a tap to thread the holes in the copper. I did use Locktite to help assure the screws stayed in place.

I really enjoyed making this speaker, and was wonderfully surprised at how well it amplified my iPhone. I plan to make other designs in the near future. Thank you.

Very impressive work on the cone.  It really looks like wood.  That said, I would just like to point out that this isn't actually a "passive speaker".  A passive speaker is a speaker that is directly connected to the input without any sort of amplification.  This is more of an acoustic amplification horn. Just wanted you to know.

Other than that, great work!

Aha......

Simple, Functional, Artistic, and its even Green! No batteries, for the speaker anyway. You just keep churning them out! Keep up the good work Sir.

Thank You for sharing.

Is that right, you drilled a hole in your phone?
Is that really necessary?
If so, what precautions should be taken?

[Horatius.Steam]

No I don´t drilled a hole in my phone. The hole is still there, the speaker outlet.
I drilled a hole in the aluminium proile, that joined the speaker out of my android phone.

Sorry for the misunderstanding. :-)


With kind regards,

Horatius Steam

PS
I will edit my instructable.....

[Horatius.Steam]

Instructable changed!

[bricabracwizard]

Hi Horatius, I enjoyed your instructable so much that I have created a link from my instructable (http://www.instructables.com/id/iPhonograph/) to yours I hope you don't mind. I also noticed that you were featured at the same time as my instructable 'easy PCB holder - so weird. Kind regards, Michael

[Dhunter1469]

I may try this for my iPod later! It looks so real and how loud is it.
PS: I live in South Africa and can make the cone insterd of buying it????

[Horatius.Steam]

Hi, you can use a piece of thick paper and roll a cone by yourselves. Use white glue and work in layers to produce a cone. The original cone has 8 layers.

You can follow this CLICK instruction.

With kind regards,

Did Theo Jansen ( tay-o yan-son) also influence you?

[Horatius.Steam]

I really like his work. This man is great! :-) Here is something more about hie work: CLICK

[astrong0]

So glad you also know who he is.

The look of the cone completely caught me off guard. I was feeling sorry for you for having to roll wood-veneer up like that (I know, i'm a hobby woddworker) until i saw the picture of the paper cone. Did you use any particular techniques for the brushwork or is the varnish you used simply magic?

[Horatius.Steam]

:-)
The magic is the wax stain. It gives nearly every surface a wooden finish.
You use the stain, wait a bit (10 - 15 minutes) then use the brush to give the surface the finish. Sometimes I have to use the stain for a second time.
Its a bit trying. :-)

With kind regards,

Horatius Steam

I have another comment, what if you made one that would probably be a bit to complicated so that you put the phone in a flap and then it folded into the body of it and still did the same thing but looked like a normal lp player.

[MitBrown]

I will be making this tonight. ill update with how it turns out!
after i try the paper cone, im going to see if i cant spot weld together a replica phonograph cone to fit it.

[agis68]

really a nice wedding of the high end technology with the steam victorian age....I love it.....5^n/5

[clockworkdoorbell]

Really lovely bit of work, I put up an instructable in a similar vein last year, but I cannot compete with your aesthetics.

elegant and effective work

[wallerps]

I have a question about the Wax Stain. Is this a product used in wood working something like a Minwax product?

Thank You,

God Morning from Germany, I used this product: CLICK  this a stain, not a protective wax.

If nothing else, it looks incredible. Makes a great phone stand

[Mrs c3po]

Nice Nice Nice!!

[wcgems]

Very neat idea... may have to give it a try.

[Thereyouhaveit]

Ahh , great idea .
Thankfully isn't a stupid dog on a old gramophone ( if you watched top gear , you know what i mean )

[Horatius.Steam]

In Germany you can buy it in nearly every store for "hobby" equipment. There is an on line store as well in Germany: HERE   
Or make it: HERE  if you make a basic form as shown in the "HowTo" you can use water based glue and pieces of an old newspaper to make thicker.

With kind regards,

Great job, your work looks awesome! Where does one find a paper cone like that??

[mdog93]

Did you make or buy the paper cone?

[Horatius.Steam]

I bought it.

Regards,

H. Steam

[mdog93]

Where can you buy such cones?

Dear Sir Hortius Steam

It is really unbelievable this creativity
Just a very good work indeed
Take a bow!!
Yours Aeon Junophor

[Winged Fist]

Amazing design! True work of art! The wax stain really gives a beautiful wood-like finish to the paper funnel. I may use this for future projects... Thanks!
