Apple looking into self-adjusting earbud headphones with noise cancellation tech

post #1 of 31
Thread Starter 
An Apple patent application discovered on Thursday describes a set of earbud type headphones that automatically adjust audio output based on seal quality, with necessary impedance data gathered by built-in microphones or electrical current measurements.

Earbud
Source: USPTO


As published by the U.S. Patent and Trademark Office on Thursday, Apple's "Electronic device and headset with speaker seal evaluation capabilities" details a new type of self-calibrating earbud that can deliver enhanced audio reproduction over a wide variety of ear shapes and sizes. Also alluded to in the patent are noise canceling headphones which rely heavily on good earbud-to-ear seals to operate.

Apple's invention is primarily aimed at earbud headphones, which are designed to create a seal in a user's ear that helps reduce ambient noise while retaining a compact form factor. When an earbud does not create a proper seal, however, these properties are negatively impacted.

Earbud

From the filing's description:

The quality of the seals that are formed between earbuds and a user's ears affects performance. For example, satisfactory noise cancellation can become difficult when is high-quality seal is not present. Poor earbud-to-ear seals can also affect audio quality in other ways. For example, left-right balance (volume) and equalization can be affected by seal quality.


To evaluate this seal, the invention proposes measuring the impedance of the speakers by taking current measurements, acoustic measurements with a microphone, or both.

As earbud impedance may vary as a function of signal frequency, impedance-versus-frequency curves can also be mapped and compared against to reveal poor seals. In addition, these curves can be used to adjust speaker output to compensate for inadequate performance.

Earbud

The filing details a number of techniques to measure impedance levels, including current sensing circuitry. Test tones can also be used in conjunction with microphones to assess disparity in output and input amplitudes. In the case of noise-canceling headphones, microphones are disposed near the ear to measure ambient noise, and the amount of required noise cancellation can be used to judge whether a seal is good.

When a poor seal is detected, actions can take the form of warnings displayed on a user's device. Alternatively, self-adjustment steps can include balance, equalization, and noise cancellation circuitry adjustments.

Apple's self-evaluating, self-adjusting earbud patent application was first filed for in February 2013 and credits Victor Tiscareno, Jeffrey J. Terlizzi, Wendell B. Sander and Christopher Todd Beauchamp as its inventors.

It's about time Apple came up with really good in-ear earphones... I don't understand how they have been offering such poor ones up to now, it's so not like them and definitely not what you expect for products of that cost .... Their offering last year was abysmal... Those earphones will NOT stay put in my ears!!

Apple'd better make it as soon as possible. Honestly apple anual upgrade is way behind time.

This audio seal test is a real eye opener (or ear opener) with regards to the difference that a good seal makes in an in-ear earphone. Basically it an all or nothing situation.

The best earbuds that will fit perfectly are the expensive ones that are custom made to fit the user's ears. But most people can't afford them.   Apple will only make something they feel is as good as they can get while still being able to market in the $30 range.

I've don't use Apple earphones but have family and friends who love the earpods. If someone wants quality earphones they don't come cheap!

I've never bothered with the newly designed ones I got with my 5. Probably because the in-ear headphones from Apple that I use are good enough for me. Anyone tried out the one that came with the iPhone5?

Off topic a bit but ear related ... I am hoping Apple or Apple Developer come up with some 'in ear hearing aids' with full audio control, by which I mean something akin to Logic Pro 9 (with simple settings too) via an iPad, iPhone or Mac. I see no reason why such a device could not be 'learning' in the same way a Nest thermostat is so that over time they auto correct for ambient and background noise, an Eagles Live concert (YES!!! Tampa 2013) and anything else we throw at our ears. The knowledge of how to profile the best experience for a specify person and their specific auditory requirements in any audio environment (including noise cancellation when required) and have that stored in the Apple eco system. I have had poor hearing in one ear since childhood after a perforated eardrum and now, with age, have a massive high end drop off, different in each ear. I am a musician, an audiophile and do not want to live in my old age missing music. I have to believe we are very close to my utopian design of highly configurable and intelligent hearing aids.

I have a nice pair of etymotics but have switched to the ear pods since I got my iP5. The ear pods definitely lack the noise isolation of the in ear monitors, but I personally don't like having my sense of hearing effectively shut off from the outside world so that's kind of a plus for me. They also fit much looser which I find more comfortable, and I think the sound quality is rather good for the price.

I, too, suffer non-compliant ear hole syndrome (nCEHS), a much understudied deficiency to the pleasures of music listening, audio books and under cover surveillance. Why this affliction has not been addressed sooner is a puzzle. Coming on the date of Douglas C. Engelbart's death is a fortuitous coincidence, which should not over shadow Apple's latest little miracle.

I don't understand comments like this.  This is purest bullshit.  

 

Whether you like the earphones or not, and whether or not they can be improved, it's crystal clear that they are far from "poor" or "abysmal."  

 

Apple's pro earbuds were in fact some of the best in class and the regular ones that they distributed for years with the iPods were good, basic earbuds.  The asymmetrical ones they came out with last year were better than their former "pro" ones and many times better than the standard ones they've been selling for years.  The choice to make these the new standard and to give them away for f*cking FREE should also be applauded.  

 

It goes against all logic to say that Apple's earbuds are not good, because if they weren't good, they wouldn't have been so popular for so long.  It's just idiotic pseudo-elitism to constantly harp on the earbuds when clearly, they are actually pretty damn good.  Again, they are FREE.  

 

The latest ones are fantastically engineered, comfortable, have excellent base and clarity and are easily as good as all the tacky black and chrome plated replacements that sell for a hundred dollars or more.  Just because you are the one in a million that can't fit them in your ears for some reason, doesn't mean they aren't a great product.

If you mean the asymmetrical ones, they are great IMO.  I was previously buying the Apple in-ear ones at over a hundred bucks a pop (usually twice a year), and the new free ones are better than those.  They have better base response and clarity, and because your ear isn't sealed you can still hear outside noises and talk without having to take them out all the time.  When others are wearing them it completely eliminates that "whispery music coming out of their head" problem too, so the sooner everyone else switches to them the better for me.  I don't like listening to other peoples music on the train.  

 

I especially like how you can be listening to your music on volume 11, yet when you take out the buds and lay them on the table, you can't hear anything at all.  

You never have to worry about whether you are bothering anyone with your music (although again, judging by the passengers on my train, I am the only one that actually cares if I'm bothering others with my music).

So according to Mikey, a good seal is necessary to maintain a compact form factor. Does that mean the if the seal is poor the earbuds grow larger? 1oyvey.gif

That's true. Unfortunately the amplifiers in iOS devices and portable Macs are probably not able to deliver the power required for those adjustments. They're sufficient for full-scale, brick wall-limited pop music, but not for anything delivered with nominal levels that leave room for dynamic range like movies or classical music.

 

What would really benefit listening on iOS devices is a hard limiter with make-up gain. That would raise the level of quiet passages to where they're audible without the loud parts either clipping the amp or overloading the earbuds.

Saying "honestly" does not negate the insincerity of this concern troll post. And a patent filing doesn't mean this is going to become a product.

No they're not. They're part of the cost of the package. That's like saying the screen is free because it's included when you buy the device.

 

I'm of two minds on this one. On one hand, Apple goes to great lengths to ensure other parts of the user experience are top-notch -- things like aluminum enclosures and Retina screens -- so it seems inconsistent and disappoints me that they settle for "good enough" when it comes to the earphones.

 

On the other hand, the supplied earphones ARE good enough for the vast majority of buyers, and including better earphones out of the box to satisfy the minority would raise the cost for everybody. Unlike the enclosure or screen, the user can choose their own earphones, so maybe its better to keep the base cost more reasonable and let those who want something better buy their own aftermarket upgrade.

What I want are Apple Bluetooth ear buds that generate energy by using the temperature difference inside your ear and the air. If not that then wireless charging (just leave them on a small charging device when you are not using them).

The cords on Apple's current ear pods snag on everything. The soft rubber texture of the cords make them feel great but also make them super snag magnets. I have already destroyed the first set by using them when I work outside. It is painful and very annoying when they rip out of your ears. I am constantly untangling them as well. It is time for the cords to go!

The problem with Apple earphones in general is that they leak sound like crazy. This creates two problems: the user has to jack up the volume very high in noisy environments and everyone can hear their music. Obviously the former problem only exacerbates the latter. 

 

Apple headphones are the bane of anyone wanting a peaceful commute on public transport or plane journey.

Then buy some earbuds that are custom fitted.  These things are inexpensive products to satisfy basic needs.  There are hundreds of other brands/models to choose from.  I know some people that like the newer design that's only $30.  But you can choose whatever you want.   If you want to buy $1,000 earbuds, there are companies that do offer that kind of earbud.

 

If they put anything more expensive bundled with the product, then the price of the product goes up.  i don't think any other mfg bundles anything much better.

Your analogy breaks down because a screen is an integral part of the device. Headphones are not; they are an included accessory and can therefore be considered free when you purchase the device.

There is nothing "good enough" about the ear pods. The old earphones were good enough, and apple completely redesigned them. They now have sound quality that beats headphones that cost 10 times as much. How much more "top notch" can you get?

These!!!!

They actually have an even more expensive model at $1999, but they don't make earbuds with microphones.  Oh well, gotta pay extra for that.

 

Ultimate Ears.  http://pro.ultimateears.com/en-us/home/ue-personal-reference-monitors

 

UE makes iPhone ready earbuds and sells them through Logitech for $399, but the other models listed above are in ear monitors for musicians and they don't have any microphone.

Well, since you're saying the ear pods are free, 10 x 0 is 0 so yes they might be better than other headphone that cost nothing. If you're going with their retail price of $29 and stating their better than $290 headphones, you're starting to spout nonsense. Outside of their actual electronic device core (Mac, iPod, iPhone, iPod), Apple is pretty dreadful at hardware.

It doesn't cost Apple $0 to make them. It cost them money in R&D and mfg cost plus packaging to make them.  But they bundle something in with the product so you have at least SOMETHING to use.

 

Apple is just trying to make the best product while keeping the price point down to an affordable price.  I haven't tried the newer $29 models that ship with the iPhone 5, but I know people that have and they like them a LOT.


For what it is, I'm sure it's better than the previous generation models.   For some, they'll buy more expensive models from a variety of brands.  It's whatever floats your boat.


But for $29 for a set of earbuds, Apple probably has the best set for the $29 price range and they just include it in the price of the iPhone 5.  Get over yourself.

 

Who includes a better set of earbuds with their smartphone?   Anyone?

The earbuds are NOT free, and while they many not be poor or abysmal, Imeould hardly call them 'good'. Fair, yes. Good, no. The only reason they are so 'popular' is because the iPhone is .

Thr latest ones are indeed a major improvement, however, there are many people who difficulty fitting them comfortably in their ears-- More than one would think. Which is why I am sure they are working on finding a better solution.
post #24 of 31
I bought the new ones - I have to say that they are far superior to the old round models in so far as audio is concerned.
I too suffer from nCEHS - so they just, fall out no matter how I try to lodge them in.
Back to Senny cans for me.

Try before you buy (if you can).

I beg to differ. A pair phillips she9550 can be had for $20 and i find them to be better than a pair of $200 sony xba-30 and the superfine silicon used works better than sony's, seals better and is more comfortable

I don't see how attached vs. separated makes any difference, but fine, let's say the analogy is flawed. The point is still rather obvious though -- the included earphones cost Apple something to make, and they recoup that cost plus markup as part of the device selling price so they are not free, period.

However Beats
Ones (which I personally compare to apples) are $100+ vs the $30. I use a $5 pair from walmart and have used free ones free have 0 quality and 1 month use. The $5 pair have a C quality and a 6 to 12 month use. Apples earphones (not pods) have B+ quality and 3+ year length. Apples earpods have A quality plus (hopefully) 5 year length. Beats have A+ quality (I do not know lifespan) but these are pointing out that (my pearsonel use) finds apple earphones worth it.

This patent looks for the (+) in my rating scale and a hopefully easier experience.

My point is that they come with the package and that they are equal in quality to many brand name add-ons that cost $100-$150.  Therefore, any criticism of them as "crap" (or words to that effect) is just beyond the pale.

This is only true of the discontinued (old) ones.  This is exactly the opposite of true when describing the new asymmetrical ones.  

 

They are specifically designed not to leak and as I noted, you can crank up the volume to the top, take them out of your ear and lay them on the table in front of someone and they cannot be heard.  How is that "leaking" sound?

post #30 of 31
The earpods are at $29 among the top in their price range, and beat quite a few worth a fair bit more. Certainly not ones costing 10x as much as stated up thread, but probably at least twice as much.
For myself, I only used them once when they were new, but have continued to use my A-Jays as I like the sound and the non tangling flat cable is a bonus.

This is a helpful invention from Apple.

 

New users of in-ear, noise-canceling earphones sometimes complain that the sound they get is terrible.  This is usually the result of not getting a good seal.  Having an alert or adjustment to the sound would help to alleviate this problem.
