简介

苹果再次扩充了他们“专业设备”的规模,这次是一对 AirPods Pro 真无线耳机。苹果的无线耳机已经是我们拆解桌上的常客了——那么这次很“Pro”的迭代会带来什么不同?我们希望这次苹果能让可维修性提高那么一点儿(改过总是不算晚),不过这些只有拆过才知道啦。

想看更多?请关注我们的 YouTube频道,以及InstagramTwitter,还有 Facebook,还可以订阅我们的新闻,获取独家拆解信息。

这个拆解是不是维修指南。 要维修你的的AirPods Pro,请使用我们的维修手册

  1. 伴随着“PRO”这个头衔而来的,是一大堆新特性:
    • 伴随着“PRO”这个头衔而来的,是一大堆新特性:

    • 主动降噪模式以及通透模式

    • 用于自适应均衡器的内向麦克风

    • 定制的苹果H1无线芯片以及第五代蓝牙技术

    • IPX4防水

    • 尽管如此,每一只AirPod Pro只比前一代产品重了三分之一,重0.19盎司(5.4克)

    • 充电盒也变得更加结实,重1.61盎司(45.6克)

    • 更大的重量并不意味着坏事——我们最新的iPhone拆解表明一些体积较大的设备,其电池寿命也相应的得到显著增加。

  2. AirPods Pro 有一个牙线风格的充电盒,打开以后能看到两个小Pods探出头来。 把盒子翻过来,我们可以看到一条产地标识以及一个配对按钮 在前几代的拆解中我们遇到了不少麻烦,因此我们拜托我们在Creative Electron公司的朋友们用X光扫描这个设备,之后我们再开始拆解。
    • AirPods Pro 有一个牙线风格的充电盒,打开以后能看到两个小Pods探出头来。

    • 在前几代的拆解中我们遇到了不少麻烦,因此我们拜托我们在Creative Electron公司的朋友们用X光扫描这个设备,之后我们再开始拆解。

    • 在这之前——既然这是一个专业的设备,我们为何不给它做个专业的X光扫描呢?请看这个精彩的360°环绕式视频。

    • 用这些 AirPods 零件你可以制作以下万圣节装扮:

    • 喷气式飞行背包

    • 宇航员的生命维持系统

    • 拆解工程师的噩梦

    The single magnet in the whole hinge system is a real life saver. No more of those metal shavings being attracted to the Airpods case! A welcome improvement and thanks for the X-Rays!

  3. 摊牌时间!那么到底“专业”二字在台面上带来了什么呢? 可更换的硅胶耳塞带来了专业的隔音效果和更合适的佩戴感受。 一个专业姿态的短且坚固的外观,和一个相似的小型充电盒。
    • 摊牌时间!那么到底“专业”二字在台面上带来了什么呢?

    • 可更换的硅胶耳塞带来了专业的隔音效果和更合适的佩戴感受。

    • 一个专业姿态的短且坚固的外观,和一个相似的小型充电盒。

    • 增加了专业级的网状格栅来平衡压强。

    • 底部的麦克风格栅会收缩和倾斜延伸出来,以进行专业的语音录制和电话通话。

  4. 我们看到了新的充电盒型号——A2190——而两个耳塞的型号被各自标记为 A2083 和 A2084。 这里还有一个“不可随意丢弃”图标,它的意思是(a)这个产品不是垃圾,或者(b)这个产品不能随意扔进垃圾桶里。 提示:“b”——几乎等同于“a”,前提是当几年后电池老化并可以更换掉时。
    • 我们看到了新的充电盒型号——A2190——而两个耳塞的型号被各自标记为 A2083A2084

    • 提示:“b”——几乎等同于“a”,前提是当几年后电池老化并可以更换掉时。

    • 在插耳机的管道底部有几个触点——用于充电的弹片触点。

    • 这些“专业的”Pods和与之对应的“业余”Pods比起来,是否会更易于维修和回收呢?相信我们和你一样激动的想要知道答案。

  5. 首先第一步——让我们来换掉最明显的可更换部件!把硅胶耳塞啪的一声揪下来。 大部分硅胶耳塞都会在其外部有一条小缝。苹果的设计使用了一些花俏的工程手法并且 (意外的!) 不兼容任何传统硅胶耳塞。 这就意味着你无法使用你喜欢的第三方耳胶,但是当你耳胶破损或者丢失的时候,至少苹果官方替换耳胶的定价仅仅只要 4 美元。

    • 虽然我们喜欢标准化零件,但是这些花俏的耳塞相比我们在普通耳机上看到的耳塞,确实提供了更大的声音开孔。

    • 现在软硅胶已经取下了,是时候拿出我们的大型(加热)武器了。 我们并不想太过放肆,但是我们相信 我们明白即将进入的地方……

    • 用我们可靠的台钳施加一点压力,就可以打开 AirPod 头部的封印。而我们的切刀可以让我们更容易的打开它。

    • 这事在产品介绍视频里看上去要简单多了。

    Apple's design uses some fancy engineering and (surprise!) isn't compatible

    I know this is just Apple’s usual “Make-Em-Pay-The-Apple-Tax!” strategy.. But I wonder if it’s also because someone else managed to patent a “groove around a fabricated cylinder, and mating circular boss around another fabricated component” (along with 6 or so professional-looking “engineering” diagrams)? If Apple used (“stole”) the same “idea”, they could be sued by some patent troll. I’m guessing they would loose - isn’t that basically a mortise/tenon joint, which has been around forever? But - given our (US, but probably other systems as well) broken patent system, it would probably constitute a not-insignificant legal cost for Apple.

  7. 首先映入眼帘的是封胶(我们一点儿也不意外,最多就是有点嫌麻烦) 第二就是——稍等,竟然用的是一个纽扣电池?这绝对是一个惊喜! 另一个吸引眼球的,是连接耳塞柄到入耳位的排线,设计缜密松紧恰当,接口使用了ZIF类型的连接座。

    • 连接座有轻量级的封胶,要做到安全分离和拆卸是相当精细活儿。我们能搞定吗?那当然可以!

    • 就当拆解进行到这里的时候,这个AirPod发出了一声小小的尖叫——硬要形容的话,大概是“嗷呜——”。我们不敢说这些东西被鬼上身了,但我们的视频团队在同阶段的拆解过程中也遇到了这个现象,他们甚至完整地录下了当时的情况,因此这绝对不是我们的臆想!。

    • 貌似我们拆解过程中的某些操作会导致扬声器驱动暂时过载,抛开理性的想法不谈,这大概是因为闹鬼了吧……

    • 接下来我们再看看那块电池……

    Apple stated that the AirPods Pro contained some sort of pressure device that can control the silicone ear tip, this can adjust the ear tip to fit perfectly into your ear. Possibly, this “awooo“ sound is made by releasing this pressure device? Just asking.

    • 嘿,等等,这看起来很眼熟啊——这是不是和三星 Galaxy Buds上用的电池一样啊?

    • 他们都是德国制造,3.7 V 的锂离子纽扣电池——但是三星 Galaxy Buds 上(稍大一点)的电池写着 CP1254,而 AirPods Pro 上这个标记为 CP1154.

    • 物理上来说,CP1154 的体积比 200 mWh 的 CP1254 小上 14%。 靠着数学的力量,我们估计该电池组约为 168 mWh。

    • 拆解更新:我们花了更长时间把玩了这个神秘电芯之后,我们揭开了上面粘黏的贴纸并发现了细小的瓦时标记!我们的猜测并没差太远——这电池官方标记为 0.16Wh。

    • 相对 AirPods 2 里面那个 93 mWh 的圆柱形电池,这可是一个巨大的提升,更接近于它的专业表亲 PowerBeats Pro

    Package on the left with the package marking that starts “YY” is a 6-axis IMU from Bosch. Package on the right with the “T” marking is a 3-axis accelerometer from STMicro. According to the tech specs the earbuds have “motion-detecting accelerometer” and “speech-detecting accelerometer.” The 6-axis chip would be used for motion so the 3-axis chip must be for speech detection.

    Trevor Yancey - 回复

    If I understand, this means no compass?

    Gavan Wilhite -

    Most likely no compass. An accelerometer suits their needs better for what would it help the Pods to know they face true north? Would be interesting to know whether they relied on ARM architecture (SW based) or whether what we're seeing here is a truly unique/customized low power chip (HW based). Especially in terms of adding and maintaining functionality.

    Dominic Bieri -

    Thanks Trevor.

    But why have they decided to adopt a 6x IMU instead of a “simple” low power accelerometer? And they have removed the tap/double tap function too… Or the gyro is there for some future firmware upgrade? ;)

    Omegauno1 - 回复

    Now I’m pretty sure the shiny apple logo “part” there is really just a shield. Below you should find more components. Looking at the filtered X-Rays (and overlapping them) I would expect to find more&larger caps, a 12-pin, and a 25-pin package at least.

    See the processed images.

    Dominic Bieri - 回复

    Dominic, you’re right! It’s a shield of some kind. We spent a lot of time trying to get it off with our hot-air rework station, but were ultimately unsuccessful. It’s constructed more like the lid of a package than a normal shield that we usually find on a circuit board. We’re going to keep trying though—we’ll update the teardown if we’re ever successful!

    Taylor Dixon -

    G-sensor is at least being used for in-ear detection. The bud turns on noise cancellation if both IR proximity sensors are triggered, and the stem is facing roughly downward. Once it’s turned on, the g-sensor is not being used for the purpose, so as to not make the buds turn off when you’re hanging upside down.

    Maybe it stops charging if humidity is detected, similar to the “moisture in charging port” warning that can appear on the phones.

Nice teardown!

Is there any way to know the wattage of the airpod pro batteries? It looks bigger than the one on the original airpods, but curiously, they’re rated for the same runtime (5 hours with noise cancellation off).

The driver is bigger, but the sillicone tip would provide a tighter seal so you wouldn’t need to pump up the volume that much. I was hoping for the battery life without noise cancelling to be better than 5 hours.

daniel.rey.lopez - 回复

We estimate it to have ~168 mWh. This is much more than the original AirPods (92 mWh), but closer in line with the other wireless earbuds—The PowerBeats Pro, Galaxy Buds, and Sony WF-1000XM3 all use 200 mWh CP1254 batteries.

Arthur Shi -

Thanks for the reply Arthur! That’s a big battery. I’ll wait for real-life battery tests, Apple may be under-reporting the expected battery life. I’m personally undecided about getting these or the Powerbeats Pro… I wish I didn’t have to compromise either in battery life or in noise cancellation :)

daniel.rey.lopez -

We found the marked rating! The battery is rated at 160 mWh. So, we were slightly off :)

Arthur Shi -

Can we get the size of the drivers please?

Bob - 回复

The drivers measure approximately 11 mm in diameter.

Arthur Shi -

Anything in there making the AirPods Pro locatable using the iPhone 11’s U1 ultra wide band chip?

seidtgeist - 回复

Great question!

Chris -

That’s what I was hoping would be announced, but they haven’t officially announced an improved Find My capability for the new iPhones we know have the U1. I think the chip is supposedly cheap enough to include, but whether it fits in such a small package I don’t know. It’s hard to see from the iPhone 11 breakdown how big the U1 chip is, and whether that could fit into the AirPods, or the Watch for that matter.

Sconnie Fella -

I think an ultra wide band chip would need too much energy and would be too expensive.

A more reasonable choice in my mind would be to use the BLE 5.1 angle of arrival feature to find the direction of the head phones, as a ble module is already on board.

But therefore an antenna array would be necessary in the phone which I don’t think is the case, and I am not sure if manufacturers will do in the future.

strat -

Think you guys may have missed something. Check your x-ray video - is there not something with a sideways “H” shape built into the lid? You didn’t look because there’s no wiring to it - so completely passive?

Frank O -

I take that back. Seems to be a spring loaded mechanism for opening the lid. But that then begs the question - Why doesn’t the “aluminum” hinge itself show in the x-ray?

Frank O -

Where’s the new custom high dynamic range amplifier

marty - 回复

Why does’t the “Pro” AirPods case have a matching stainless steel hinge versus the decidedly less pro aluminum?

Chris - 回复

The ghost sound was likely the gasket that helps equalize pressure, methinks? Reviews said you can hear them blocking your hearing like normal IEMs for a second, and then they “release”, and then you feel unblocked.

tipoo - 回复

We are pretty certain that the driver produced the shrieking sound—the sound was not the result of a mechanical phenomenon. If I were to guess, it might be from feedback by the noise cancellation mics in close proximity to the driver, especially as we were taking the casing apart.

Arthur Shi -

I think they are made to be easier to recycle, but not repair.

David K. - 回复

On Apple’s webpage where the inter mic is explained, it appears that the speaker grills are detachable (and thus washable separately). Can you please confirm?

Jeffrey - 回复

Unfortunately, none of the speaker grilles are detachable/removable. They are glued from within the case.

Arthur Shi -

Can you share any details on the battery? Assuming it is Varta… but what capacity do you find the 1154 to coming in at?

Brian Spatocco - 回复

There are no markings that could allude to what the capacity is, other than a data matrix that’s really hard to read.

I measured the batteries, and compared to the Galaxy Buds’ CP1254 batteries, these CP1154s are 1 mm smaller in diameter (12 mm vs. 11 mm). They have the same thickness—5.4 mm.

If you calculate the volume, the CP1154 has 16% less volume than the CP1254. Considering that these are the same battery chemistries and forms, I’m estimating that they have similar energy densities, and thus would scale with volume.

From those measurements, I would estimate that the CP1154 would have ~168mWh (compared to the Galaxy Buds’ CP1254 having 200mWh).

This is much bigger than the AirPods 2, which has 93mWh.

Arthur Shi -

Thanks Arthur! That number makes a lot of sense to me, too.

It’s curious that they didn’t include any capacity/energy markings on the device considering the fact that other Varta SKUs do tend to have this. For example, CP1254 Varta cell in the WF-1000XM3 (https://hifigo.com/blogs/tws/deep-dive-t...) provides the nominal at .2 Wh (as you noted).

Makes me wonder if this was a unique production run just for Apple.

Brian Spatocco -

Did you find an IMU in the earbuds?

Gavan Wilhite - 回复

A comment in Step 10 seems to point them as Bosch and STMicro IMUs.

Arthur Shi -

Can’t help you on the chips, but the microphones are from Goertek, as they have the “GW” marking.

See page 6 of this confidential datasheet for another mic in the same range. If you can get a high enough picture of the datamatrix code on the microphone, it should contain the part number, but the photos are too low resolution for me to read it myself.

chris - 回复

Thanks for the tip!

Arthur Shi -

Found out that this tool does it with the available resolution:

https://demo.dynamsoft.com/dbr/barcodere...

DATAMATRIX DTV93715PEKL8141N+DC

Unfortunately it doesn’t align with any of their known part numbers.

chris -

For what it’s worth, the battery probably adheres to the following logic in it’s nomenclature:

xxyy, where xx is the diameter in mm, and yy is the height in 1/10th mm (which ist why the 1154 is slightly smaller than the 1254).

Michael - 回复

You are correct! The 1154 has an 11 mm diamter, while the 1254 has a 12mm. They both have 5.4mm thickness, as you predicted.

Arthur Shi -

I am just gonna add this comment real quick cause I got redirected her from a local newspaper. Repairing the air pods, regardless of model, will be far more affordable and practical depending on where you live. In Norway for instance, we have a legally required “warranty” which lasts for five years. The batteries are covered for two years. That means that if the pods fail at any point during those five years, and Apple cannot prove the user is to blame for the fault, they have to either repair it, refund the purchase, or provide a new pair, free of charge. The battery is covered for two years, beyond which point Apple must provide repairs for an affordable price.

In case anyone is wondering, this issue has repeatedly gone through the Norwegian court systems. Apple has lost every single time.

Why would Apple use a cell battery here?

nickkiran - 回复

Perhaps they went with a larger battery so they can limit it to 70-80 percent charging cycles in order to increase lifespan before it croaks, say discharge to 10 or 20 percent, charge to 90 percent so it doesn’t kill the battery as quickly? You’d have to tear one apart at full charge and at empty to measure the voltage to get an idea but its a thought. Since the battery is almost double the capacity, sacrificing 20-30% of that capacity for increased cycles still gives you a larger battery capacity than before. I’d think it would be foolish not to do this, but who knows if they thought that.

The video of X-ray is soooo cool

it helps a lot in understanding the 3D structure

that feels amazing! it really give a sense of “so it’s constructed in this way…”

please do it with iPhones and other stuff next time!!

By the way, if that’s a pressure sensor not a real physical button that mean Apple has created a virtual feeling of clicking of the button :0 I thought it was a button, the click feeling of the antenna feels so real..

Could…we give future devices like this negative repairability scores? Because trying to repair things like this will take away your time AND break the device.

Great teardown! Do you have the batteries weight by any chance?

Luis Vollbracht - 回复

Hey Luis, thank you! The battery weighs 1.2 grams.

Is it still Knowles making the microphones? And there are 3 each?

Nice teardown!

Is it in anyway possible to change the shape of the indent in the case holder to fit a right airpod in the left hole? I ask because I am deaf on one ear and will team up with a friend who is deaf on the left, swap one airpod to get a set of two (right/left - you get the idea). But will it be impossible, possible with, say a bit of drilling/scraping/… or easy to fit two right airpods in one case?

Why don’t your teardown other earbuds ? I guess you just wanna some easy pesos with Apple bashing . Like you guys often seems to do…

will - 回复

I’ve never heard of anyone having a pair of ear buds repaired.

Being cordless, and because Apple will sell each of the 3 replaceable components separately, repair couldn’t be easier.

I think you guys have completely lost the plot.

A single Pod will cost about 90 USD to replace with Apple. So yes, repair couldn't be easier if you just go and buy a new Pod at the Genius Bar. But it's going to be pricy.

To be honest the case deserve a score more than 0. The case along should get a score like 4.

The two pods, well … those get scores of 0.

This battery is a German-made VARTA Valta CP1254 high capacity A3 60mah3.7v lithium battery

Deng lei - 回复

They are probably made by VARTA as you guessed. However, they are CP1154, rated for 160 mWh, so ~43 mAh @3.7v.

Arthur Shi -

As per your experience, can we disassemble them safely and fix it into another body (planning to make a Gold Airpod Pro). I can make the Gold body and close it also. But, should be able to dissemble it safely and put things back. You think its possible ?

Does anyone know what sort of flash memory is being used in the Airpods Pro? I know the AirPods 2 had the following memory chip serial number in it 25SL 128A 1820.

Does anyone know the maker or serial number for the flash memory being used in the Airpods Pro?

ApplePro - 回复

Do the AirPods Pro or the case itself house liquid contact indicators?

Edward Anguiano - 回复

What MEMS motion sensor is in there?

andrew mcneil - 回复

I have been thinking about switching to Android for a while. Get a half decent phone from OnePlus for half the price. I ended up getting the iPhone X 2 years ago because I had the Airpods for 6 months by then and absolutely loved them. With my batteries so crappy on the Airpods, I don’t think I will get a new set, specially considering their latest creation is no better for fixability. I just retired and can’t afford the extra premium for Apple products anymore. Apple is really losing its shine.

'“This little silver guy lives near the top, right between the charging pockets for the 'Pods. What's it for? It looks a bit like a microphone. “

…so what is it?

Si Brindley - 回复

This might have been asked, is there a water Water damage sensor?!?

Shashank - 回复

Do they come with a wireless charging case?

Trevor - 回复

Yes, the case supports both wired and wireless charging.
