DIY Headphone

[AudioTime]

Hi,

Not sure if this the right place.

My Creative aurvana play 2 headband is broken, and I thinking to replace the housing to this: https://www.aliexpress.com/item/1005004041053880.html?spm=a2g0o.cart.0.0.3aae38davtoGEJ&mp=1

Any suggestion on what I should be aware of?

Regards.

I can't find any information about the Creative Aurvana Play 2, only the current Aurvana Live!2, which has a 40mm driver.

If the size (volume) of the cup in the replacement housing does not match that of the Aurvana Play 2, transplanting the drivers is likely to result in a different acoustic performance.

I see that the replacement housings come with a choice of driver diameter mounting plates and has individual cup entry wiring. So hopefully the actual physical transfer would not be too problematical.

It's all down to cost effectiveness versus risk assessment I guess.

Let's see if my reply attracts the attention of someone who has undertaken such a transplant.

My bad, Ya, it is Auravna Live!2.

It is using 40mm driver, and the replacemnent housing has that driver diameter.

I feel that it may be a easy transplant,

Anyway, I managed to push out one of the driver. Hope I did not spoil the membrane.

Like to confirm, is the "red" wire positive, and the green negative?
And is there any effect of the paper? To reduce the resonance in the earphone?

 

[Galu]

Yes, red is usually positive.

By "paper", do you mean material in front of the driver diaphragm or inside the cups?

If inside the cups, it is there to absorb sound reflections.

 

[Galu]

I did an edit there as I wasn't sure where the "paper" was located. I may see better when I view your images on my laptop.

 

[Galu]

Looking more closely at your photos, I suggest the red paint spot indicates that the right hand terminal of the driver is the positive one.

I'm still not sure what you mean by "paper". Perhaps you mean foam material?

If it's the material built into the removable ear pads, then it is there mainly to prevent dust and foreign particles from fouling the driver diaphragm (which is located behind that protective metal mesh).

 

[PRR]

not sure what you mean by "paper".

I see an open "felt" material over the holes in the back of the driver. One in the middle and a dozen? around the edge. Probably damping, and probably different by design, not blindly copied one to the other.

"Works!" headphones are easy. "GOOD!" headphones need a lot of tweaking. It may be wise to just buy new phones.

 

[AudioTime]

With regards to the "paper", in the second photo from the right, there are 2 concentric white circles, where the inner one is thinner in width. I believe it is for damping.

@PRR, I sort of have to agree with you. In fact, the housing that I am looking at is cost more than this headset. But, I feel a quite wasteful when it is just the frame that is broken, not the main component.

 

[Galu]

I see now that the outer ring of "paper" shown in image 2 has been removed in image 3, exposing the openings in the driver frame.

The fibrous material may have been included to provide damping, or simply to exclude foreign particles.

I suppose tissue paper could be used in its place.

Fingers crossed that this random marriage of driver and housing will sound good to you. Do keep us posted.
