How did you make it? It makes noise or what? Does it sound good?
What kind of box do you have it in our are you just running it like how it shows in the picture. |

| Hi BudP: the sound is clear enough,only problem is the Valley,you mean paint the acrylic on the cone? it well make the cone heavy,High frequency will down, not good idea,i tried already. |

Hi Chinese,
Very small thickness of paint. Flat, clear, acrylic paint, very thin, applied with calligraphy pen, so control amount of paint Make pen strokes only where black blocks are shown on conic section. Add very little mass, not mistreat high frequencies, remove standing waves and reflected waves at end of cone. Also at beginning, even less paint, much smaller pen tip, much smaller stroke. Only to control area at cone surface and air, boundary layer, not control piston with mass, only bending surface where all energy is emitted.
Try or not, your decision, works well on other side of the planet from you on all speaker types available. Maybe learn and try on regular cone speaker, cheap, maybe 200 cm diameter.
Bud |
|
|
| chinese |
BudP: 200 cm diameter?!!
here we call "Damping rubber"
you send it to me? why you need the measurements? |
|
|
| BudP |
Chinese,
Sorry meant 200 mm
Dimensions to put into my program to provide marking template for correct position of pen strokes. Need final diameter, beginning diameter and length of cone wall, not height of cone, actual length of surface.
This is not damping rubber. This is a thin paint, dries hard, 80% moisture which evaporates. Stiffens paper fibers on surface and just under surface. Not mass damping. surface control of ends of cone area and also the entire cone surface, just from ends of cone, where ringing begins and reflects.
Bud |

| now i'm making a 8 inch full ranger unit, the High frequency will more than 22000HZ, lower frequency reach 100HZ,blow 100HZ giveup,user can add a sub woofer or use Labyrinth box,because the full ranger can't be Perfect,like lowther's Mentality . :bawling: |
|
|
| BudP |
Chinese,
Close. I will mark up your diagram for dimensions preferred and one more I must have. This will take a small amount of time.
Would you trade expert information on paper technology? I do not want to make your cone, I have other ideas and other projects but paper is only made in factory in USA, or by hobby people for celebration cards. Speaker cone makers are very secretive and do not want to have my expert ability in trade.
Bud |
|
|
| BudP |
Chinese,
Here is your drawing marked with one dimension I need and one I prefer. I would have to rewrite a part of program to use cone vertical height. It is now written for cone surface height as shown.
Bud |
|
|
| chinese |
| It's very very difficult to made this cone,and only can made by Human hand, Machine can't do it, 14 inch only 17g with Very good Rigidity and Suitable Damping,it is Secret. |
|
|
| BudP |
Chinese,
I do not need to know your secret of damping. Funny looking dots on surface will take care of that. I only want to know how to make cones by hand, not with machine. Want to make different, very shallow depth and smaller diameter. Maybe only one step, not three cone steps like yours.
Trade my knowledge for yours, I keep some secrets for you to discover if you need to know them, you keep some secrets I do not need to know.
Bud |
|
|
| chinese |
| i made it only by hands,can reach 20000hz. |
|
|
| BudP |
Much more interesting to me. I prefer to make conventional cone without ribs, but with light weight paper, made by hand.
I have a conic section completed to your dimensions. Do you have a program that will read Auto Cad DWG or DXF file format? If not I will send a full size JPG to you via email tomorrow. It will take some time to convert and do a good job.
Bud |
|
|
| chinese |
| if not three cone steps,maybe the High frequency can't reach 20000HZ, because each steps are Mutually cooperates:D |
|
|
| chinese |
| JPG is better, i don't have Auto cad |
|
|
| BudP |
Chinese,
I will put it into jpeg format tomorrow. Will your email address from here be best or do you want to send me a direct email and I will send direct back to you?
The pattern is called EnABL here in the USA, just so you know. I am not worried about 20 k Hz as the pattern will allow cone to produce this frequency and down to below piston point also.
Maybe steps will be needed. I would need to experiment, but do not have the skill. Can you transfer enough knowledge with pictures and simple explanations? It would be better if we could work together but the pacific ocean does not get smaller.

|
| hm |
Hello,
cool, very cool, congratulation.
Yes to do it better as Lowther is possible,
cheaper as AER also.
My question:
works it also as a bending wave transductor, like DDD
and Manger?
Did you make measurements to find the 2kHz problem.
Is it more a problem of membran contur, or a partial
effect of the membran itself? |
|
|
| chinese |
| i will solve the problem, the frequency line not mean the result,if you saw lowther unit frequency line, you will never buy it,but it's sounds very nice, why? something we can't explain. |
|
|
| hm |
You are right, don´t believe in frequency lines.
What is about step response?
Bending wave ?
The 2 kHZ problem might be a problem of the
dimension of the membran construction and or
mechanical membran lack, search for this part
of the membran, thin second adhesive might help.
good luck |

Interesting and serious :cool: with your chinese paper art, it looks like you can do almost anything you like
http://www.diyaudio.com/forums/atta...tamp=1175318306
Very inventive but I am also kind of a conservative guy.... look at the shape of a violin, havent been changed fore hundreds of years and cant be improved
I would like to see a small membrane made with integrated surround, to be used as mid/tweeter - made with your paper artwork
Or the "ringradiator" like you show in the picture, could be interesting in a small version.... without the surround |

| gamma |
| chinese: so light and big cone ....Impressive. I hope i will see moro of your creation in the future. |
|
|
| chinese |
the steps is very Important,when it work in High frequency i hope only the first inside cone working,when in low frequency the whole cone working, it is my design Mentality and it seems working well.
i can do almost any size of full ranger unit what i want. i also done an Earphone before,it's a small full ranger speaker. |

Interesting about the Gif. The full size jpeg's are 250k and 530 k files. If they become Gif.s is there a way to make them available here on the forum rather than as an email attachment to Chinese? I have to admit ignorance about the abilities of Gifs and would really preffer mounting the full scale file here so all can share. I will export them to GIF. They are currently Corel vector files and only about 35k but not everyone has Corel or the original program they are created in, Auto Cad.

The Gif of the 530 k jpeg is 145k. |

Gif is a non-lossy format, and given the nature of your drawing, you should be able to save out a 1-bit (ie B&W) gif... i grabbed one of your patterns which was 48 k as a jpg... removed the noise (which unfortunatly also means a bit of detail loss on the edges (which would not occur if you start from the vector-artwork). I ended up with a 13k file at 2 bits (necessary because it started out as a jpg) but a 1 bit file was ~10k. So not only is it smaller, the quality will be better (if not passed thru jpg)
I can help you work thru this, i can read & write an aweful lot of formats. I'll send you an email so you can attach a sample dwg and we can see what can be accomplished)

hi there, sorry to hijack the thread, but BudP, if you're doing it in ACAD you can automatically "print" to desired Bitmap format (try for instance .Tif) and then in photoshop or similar to .gif like planet10 said.
regards and chinese by the way, congrats on your design!!
Bruno H.
ps. you've got to add a printer in autocad for "raster file formats", you do have Jpg and tif as well already there! |
|
|
| BudP |
Chinese,
I have the cone pattern placed on an A4 letter size sheet of paper, 216 mm wide X 280 mm long, except it is 25 mm longer, so you will need to set your printer for 305 mm and hand cut a piece of paper. I cannot send this GIF file to you through this forum, and cannot mount it as an attachment as it is too large at 145 kb.
Can you send me an email so I may return the file to your email address. I will not pass this email out to spam makers or to other people.
Bud |
|
|
| BudP |
Carcass,
Thank you for your comments. I do use the Auto Cad rasterize for some bit maps and have used it for very high quality Tiff's from 3d solids machine designs for assembly instruction manuals and the like. In this case I need to use Corel as an intermediate step so that I can scale and stretch the conic section cut out to exactly fit the cones in question as some will be applied to the normal front and some to the normal back.
I have not produced templates like this before, having always used a calligraphy pen to apply the blocks. In another thread we are working on actual templates, made from sunlight exposed photo resist coated silkscreen material, that appears to have the properties needed for applying the pattern with a foam brush and using the silkscreen, with appropriate holes opened in the coating, as a mask.
If this works as expected it will open up many different finished drivers to treatment with the EnABL process.

| the different way to make the cone.;) |
|
|
| BudP |
Chinese,
Would you make cones to order, with motor and spider? I am very interested in a Walsh cone tweeter, following Lincoln Walsh's cone angle profile. I am also interested in a Walsh mid range / tweeter. This was the reason I asked you if you could teach enough about your paper making skills, to someone on the other side of the pacific ocean, to allow making these small simple cones.
I am certain that if the price was affordable, many people would be interested in these products. The cone tweeter would not need a support on the large diameter end and it would stand up, with the open end pointed at the sky.
perhaps 100mm tall
The midrange would be a more normal story. We would still be listening to the backside of the cone, with the more normal inside being damped in a box.
I have attached a picture of a full range pair of Walsh speakers for you to look at, so that my comments make more sense.

BudP: i saw the two pics already, In fact i can't Completely understood your email letters, i use Translator already ,what do you want me to do? if i can ,i will help you. can you Translat your letter to chinese so i can Completely understood.
i am also interesting with this speaker. |
|

| chinese |
| and this speaker, very interesting, i want make it. |
|
|
| BudP |
Chinese,
Sorry, I forgot you use translation software. I want teaching in paper making. I want to make 100mm tall Walsh cone from light rigid paper. I have no skill, no knowledge. Can you teach by pictures?
If teaching is not a good idea, can you make 100mm tall Walsh cones? Can they fit on your current voice coil and magnet motor, with flexible connection but not top piece? Open cone, empty. I can assemble voice coil with cone into magnet here. I have made many speakers from parts but have not made cones. You can make a small business out of this Walsh tweeter idea.
I like your ideas and want to know enough to make my ideas real. Please think how you can teach with pictures, and a few words. I can show how to apply EnABL to help with small details not corrected by your paper with damping. I do not need to know about secret damping material.
Bud |

Hi Chinese,
Are you aware that this speaker is completely different from traditional cone speakers? With this speaker, the object is not to try to make the cone pistonic. The principle is to have bending waves travel from voice coil to rim, and while doing it radiate sound. So, in this case the material and its bending modulus are the important characteristics, not weight and stiffness.
The principle is similar to teh Wash concept. Most people are not aware that the Wash (and DDD) principle is completely different from traditional cone principles; there is a whole thread on Wash rebuilt somewhere here where that issue is ignored or unknown.

| Kensai |
chinese,
Very exotic and wonderful looking stuff. Thanks for sharing.
I don't think the dip in the upper mid frequency response is going to be that big of a problem in practice. Ever since I got the capability to very finely equalize my sound, I have a tendency to notch out around 2200Hz on everything I own, (Kenwood KFC-6949s, Pioneer B20s, even my Grado SR80 headphones). There's just something distinctly unpleasant, IMO, about too much energy in that region, so maybe the reason your 14 inch cones sound nice is that their natural problems with reproducing this frequency range is actually a good thing.
Good luck.
Kensai |
|
|
| chinese |
hello Kensai: thanks for your reply.
i always thinking one thing: the speaker has a frequency line, but dose people's Ear has a Listening line? because Ear has different Sensitivity with different sounds, so i think Ear must has a listening line and the line is not Straight. it's a curve,the more Complex thing is different people has different curve,and the curve will changed with people's age.so when the speaker's frequency line can fit people's listening line, people will feel the sound very nice,if can not fit,even the frequency line is so good,people will not feel good, am i Correct?
so i think in the future, maybe speaker "Quantity body custom make",one sound system is only for one person.:D |
