Mr. Speakers ETHER Flow Headphone(?) Upgrade(?)

Agreed will be interesting to see if incriminating posts are being deleted.

 

I've been a moderator on a few boards, I wasn't able to see if someone visited a post. That was several years back, maybe things changed.

 

Ppl reporting back from a meet say the ether C is less bright w more bass.

 

I've been curious about fazors before but not to the point a running an acoustic simulation. This time, given the promised changes in ether's response, I am very interested in trying to use simulation to get a grip.

For one, this air flow simulation makes no sense whatsoever to me, acoustics isn't just like breeze going through holes...

Then, there was mention of acoustic waveguide but someone rightfully pointed that this can't be real in the audio range given the small changes in geometry relative to acoustic wavelength.

Along the same lines, I can't imagine acoustic diffraction effects being large at frequencies of interest.

So that leaves us with one last aspect of perforated panels: their ability to focus sound absorption at specific frequencies (helmholtz resonator type behavior with the entrapped air in the perforations acting as mass).

The audio/acoustic nerd in me wants to understand this one so I asked him if he was interested in sharing a bit more details. Really all I need is a single dimension like the rail width or length and can run with this.

In the end, just modeling the perforated grill may not be enough (for instance if it's affecting the effective damping of the diaphragm), but only way to make sure of this is trying different simulations.

I read before that perforation on estat stators influences effective damping of the (very thin and light) diaphragm so I wonder if this is the connection Dan is making.

Cheers,

Edit: sp.

 

C or O?

Edit: assuming O since the title of the thread isnt for the C
I better look at the qualifications for these programs .to see if I would make the cut

 

If the modder files for a patent as he's saying he'll do, does it mean mrspeakers may have to license this tech from him?

 

HF won't. And it's really not needed. The modder's own publication of the design on the internet dating back a year ago should qualify as establishment of a "prior art". Dan has also likewise stated that he'll exclude the overlapping elements of his own design from the Mr Speakers patent. As he should.

If these guys are going to lawyer up and take it that far, anything could happen. There would need to be a judgement for the modder, though. Or some settlement. And getting to that point would probably involve non-trivial expense for both parties.

Me, I can understand the shock and anger on the part of this modder to see what appears to be his design suddenly appearing in a commercial product. But on the other hand, he clearly wasn't trying to keep his design a secret. And at the same time, he also doesn't seem amenable to being given credit for the design by someone who appears to be using elements of it. So I wonder WTF he *does* want and why he posted it publicly in the first place with seemingly no intent to patent it until now.... Who knows. What I do know is that, at this point, I'd much rather be talking about audio.

 

Would be cool if we could get the Ether Flow and Elear loaners at the same time. I for one think it would be amazing to be able to compare the two side by side.

 

Not really that odd. Again, taking Dan at his word, he built the headphones not knowing of the other modder, thought he had something unique, applied for a patent, released his info, learned of the other modder's work, then acknowledged it and wants to give credit where credit is due. The sequence of events is entirely plausible.

Idle chat disclaimer applies

 

Sorry, do you mean the Ether C Flow vs. the "classic" Ether C? Or do you mean the Ether C vs. the Ether?

 

ether c flow less bright and more rich than ether c

 

You auditioned the ether C flow gbeast?

 

no was clarifying a post of mine. Please read above

 

There was someone in the thread that mentioned acoustic compliance/impedance and that was one of my first thoughts as well.

Perhaps another way to look at things is as a diffraction grating rather than a "waveguide", because as you mentioned the features seem too small to have any effect on sounds within the hearing range. Having the tapered holes basically moves you a couple wave iterations up and decreases the time/distance to achieve a more uniform wave front. Here's a nice animation:

edit blargh 3am too sleepy to think properly

 

Lmfao. Well done bro.

 

Credit to greenwiki on HF, but for those that recently purchased an Ether or Ether C and are feeling the pinch of the lower price, check your credit card. Some have price matching protection. It's a little hassle to claim it, but it may be worth the time for you.
