这个拆解是不是维修指南。 要维修你的的AirPods,请使用我们的维修手册

  1. 好吧,我们已经拿到了苹果的最新圣诞长袜填塞礼品,它正在在我们的拆解桌上。是时候看看它的构造了。目前已知的信息: 每只 AirPod 重 0.14 盎司(4 克),充电盒重量为 1.34 盎司(38 克)
    • 好吧,我们已经拿到了苹果的最新圣诞长袜填塞礼品,它正在在我们的拆解桌上。是时候看看它的构造了。目前已知的信息:

    • 每只 AirPod 重 0.14 盎司(4 克),充电盒重量为 1.34 盎司(38 克)

    • 每只 AirPod 的大小为 16.5 mm × 18.0 mm × 40.5 mm,而充电盒的大小为 44.3 mm × 21.3 mm × 53.5 mm

    • 利用蓝牙技术和苹果的 W1 芯片进行无线连接

    • 使用麦克风、光学传感器和一个运动加速计来进行入耳检测

    • 采用波束成形技术的麦克风加上一个额外的加速计来过滤外界噪音

    • AirPods 单次充满电可以使用 5 个小时,而配合充电盒使用则可以超过 24 小时

    Has someone checked the battery lifetime in cold (freezing) temperatures?

    Peter Goedtkindt - 回复

    I guess in cold temperature you should have the gear covering your ear or ear is warm enough for airpods. If your airpods are left in cold environment for a while and you pull out to use, that is different story.

    How long does it take to charge the airpods by the case?

    Jim Ngo - 回复

    Do not buy, case will die after the warranty is up, and you will be forced to shell out another $70 for a new one. Buy another brand… AirPods suck, and fall out anyways.

  2. AirPods — 有一个很有特色的电子苹果蛋! 在充电盒的一端,配备了用于充电的 Lightning 接口。 在另一端,则是放置 AirPods 的嵌入式耳机放置槽,放置槽底部分别有两个触点来为耳机电池进行充电。
    • AirPods — 有一个很有特色的电子苹果蛋!

    • 在充电盒的一端,配备了用于充电的 Lightning 接口。

    • 在另一端,则是放置 AirPods 的嵌入式耳机放置槽,放置槽底部分别有两个触点来为耳机电池进行充电。

    • 最后,在充电盒的顶部(两个放置槽中间),我们发现一个小小的 LED 状态指示灯,它可以在三组电池都没电的情况下提醒你。

    • 如果你有一双“X光眼”,那么你可以从头到尾地看清它的全貌。请睁大你的眼睛,跟着我们的拆解一步步地“扫描”一下AirPods吧。

  3. 在充电盒的盖子下方写有产品型号:A1602,也提供了充电盒总的电池容量信息:398 毫安时。 在执行我们最后一个拆解仪式之前,我们快速地看一下后面的设置按钮。如果苹果非常推崇的即时同步(配对)功能失效或者不能用了,通过这个按钮也可以使用传统的蓝牙配对过程。 好吧,不浪费时间了。我们进入正题。

    Your description of the button on the back of the case is incorrect. The instant sync capabilities are actually automatic and happen right when you open the case, the button on the back is just for manual pairing with other bluetooth devices.

  4. 耳机上有一些开孔:栅格是给扬声器的,麦克风开孔是给那些降噪麦克风用的,黑色的孔是红外距离传感器。 左边和右边的耳机产品型号也不同,分别是 A1722 (左)和 A1523(右)。FCC ID 分别是 BCG-A1722 和 BCG-1523。 X 光可以让我们看到其内部构造。一些栅格,以及麦克风,其余的神秘部分会慢慢解开。

    • 为了安全起见,我们接下来使用一个撬具来撬开它。 慢慢转动就可以将扬声器部分从耳机中分离出来,并且可以看看到内部的零部件。

  5. 我们追求拆解电子设备的旅程并没有让我们失望。我们看到了一些精密的元件。 在我们开始拆下主板、线缆和其他一些零碎的东西时,我们感受到了某种可穿戴设备的修复噩梦(*咳* Apple Watch *咳*)。 如果把复杂线缆塞进一个小空间内,接着用大量的胶水密封是个游戏的话,苹果一定会赢。

  6. 此时,我们暂时停滞不前—留在耳塞里面的是一堆混乱的电缆和粘合剂,而且似乎找不到出路。所以我们转向耳机根部,希望能够找到另一个突破口。 这下,我们遭遇到超级多的胶水。 这个闪亮金属盖 在充电时提供触点,而且包围着主要的麦克风。隐藏在一堆胶水之间,我们终于瞄到了电池线缆。

    no it is probably not hot glue.

    But hmmm isopropyl alcohol…thanks for that tip @mfx

    on the other hand, yes, having the ability to having the entire thing be glue-free smells really good.

    Maybe you can just prepare a beaker full of that and dump the entire thing (case, left pod, right pod) in and put it on a … the shaking plate?

    whatever.

    • 如果你厌倦了其它设备,外部都有明显的进入点,那么这个你就兴奋了,因为完全需要采取手术级别的手段。 护士,把手术刀递给我。

    • 使用手术般精确的手段把外盖给切开,我们看到里面是盖在电池上的天线。

    • 好吧,我们没有外科医生的耐心。出来一点之后,我们就暴力地撕开了它。

    I think the way they did it is shoved the battery through the bottom and glued it to the cap. They then microsoldered the contacts to the board. It’s crazy how intricate this is!

    I assume this is a 1.5V battery?

    mdg1111 - 回复

    What is the charging voltage for the headphones?

    Bogdan Mirkac - 回复

    Probably the same as a normal Li-ion

    Oliver Watson - 回复

    Who manufactures these tiny batteries?

    Chaim b. Abraham - 回复

    AirPods charge very quickly. What is the full charge voltage? I assume to maximize lifespan/cycle life and charging speed they don’t actually charge to 4.2 volts or whatever the 100% SOC voltage is for that chemistry. Also any idea what the chemistry is (LCO, LMO, NMC, etc?)

    Kyle Sweeney - 回复

    Without any evidence (from multimeter or “experiment results”) I reason it is a 1.2V cell, type AAAAA.

    From the flange on the battery to the left and the suspecious look of the supposed contact points for it.

    *Very quickly* was a bad unit for charge time. 1 hour full? 30 min full? (FULL, not able to use again)

    if 1 hour full then charge current is 93MA. 30 minute charge is 186MA, so on and so forth.

    I guess Apple had this thing on 1C charge (93MAH—>1 hour @ 93MA). 2C charge will just wreck this battery.

    Xavier Jiang - 回复

    One of my airpods broke, so I pulled the battery. By my measurements so far, and I'm still testing it, The full charge voltage is 4.2v giving it about 22mA. I'm still doing some testing, but I'm capable of rapidly charging it at that voltage and also draining it at that voltage.

    Further testing is required.

    Check out edgewater wireless. They specialize in wifi technology , multichannel wireless , reducing interference, etc. they hold 24 patents. A lot of their tech applies to any wireless protocol. In 2015, apple bought a patent off them for front end power effiency ( us patent 7016654).The deal had “strong commercial terms attached “. I beleive it is Edgewater’s tech that apple used to enhance the airpods when they were designing them with the patents acquired during the passif semiconductor acquisition. Confident that we will see technology from edgewaters patents inside the w1 chip. It would be what gives the airpods the incredible battery life, amazing connectivity, and the ability to sync a seperate signal to each pod with no interference. How do you get to the bottom of the inner workings of a chip in order to discover these patents?

    JD8510 - 回复

    Why is the audio codec stereo? A single 'Pod only puts out one channel of audio, obviously...

    ncb - 回复

    Because if it was mono, the output wouldn’t be stereo, it would be twin-track mono, which isn’t the same thing! Twin track mono is the SAME sounds coming out of both ‘plugs, stereo is DIFFERENT sounds coming out of EACH plug! Chris.

    Christopher Burke -

    @JD8510: "How do you get to the bottom of the inner workings of a chip in order to discover these patents?"

    Well, there are optical techniques to do so after you've striped away the housing with nitric acid. I even heard about tecniques, where layer by layer has been removed from such a chip to get to the inner workings. And if you've the money and therefore the material to do so, you're even able to read out single bits of memory cells. OTPs by optical ways, others by using a scanning electron microscope...

    @ncb: IMHO there are no such small mono codecs on the market, as the additionally used space is much smaller than the advantace you're getting by adding a second channel. Most of the chip area is used by the core functionalities of the codec anyway.

    Simon - 回复

    TPS743 IMHO doesn't exist. Think it's a simple TPS7430 or TPS74301 LDO from TI.

    Is there someone who understood the working of the antenna? Well, it's attached DIRECTLY on the battery. Normally this won't work, as the antenna would be shortened in a RF-way. But maybe the whole battery compartement is decoupled in a RF way from the rest of the PCB? Means the battery itself would then act as an antenna as well? Clever, if this is working like this. Any comments?

    Simon - 回复

    any one know the sound is generated from W1 or chip of maxim?

    lucas wu - 回复

    Can someone x-ray that part and see whats inside it?

    Subash Patel -

    @ncb: I think that by only using one single AirPod, the incoming bluetooth stereo signal is actually downmixed to mono. In fact you're able to hear both channels on this sole AirPod.

    It's interesting that Apple filed the FCC with request for confidentiality on the antenna..

    So much for “progress of the arts and sciences”.. Only if Apple decides to make such progress, and never in any technological field *other* than what Apple currently uses them (could the technology be useful for antennas attached to pill bottles or as part of some kind of long-distance movement tracker perhaps? Who knows.)

This small chip is according to the Texas Instruments website a programable Start-Up Sequencing chip to control things such as temprature and voltage while starting up. Apple may have a special version of this chip inside of the AirPods. For more information on this chip http://www.ti.com/product/TPS74301

do the airpods feature the same driver as the earpods?

Jason Wilson - 回复

Great question, trying to find this out myself.

SJDragonetti -

It looks like it's a bit different. The EarPod teardown has a pretty nice comparison of the generations of earbuds from Apple in step 11. They look like they mostly have open-back designs while the new AirPods have a black plastic (and mesh?) that covers the back of the driver. Apple EarPods Teardown

I would be interested in seeing these compared to the new PowerBeats 3 since that headphone model also uses a membrane-style speaker in the midsection bulge of the stem.

Josiah Knoll -

It wouldn't really matter. The EarPods had a lot of tuning done to them through the ports on the front, back, and stems (cover with tape and see what happens). The AirPods have ports moved as well as less air in the housings (replaced with logic boards, batteries, and other electronics. So even if they do use the same drivers, they'll sound substantially different.

Marcus Nguyen -

I'm curious if you were to design something that small with the same capabilities how would you A) not use glue and B) make it somehow "easy" to repair

johnnyrotten1 - 回复

I don't think you can get away without any glue. It's a question of using it effectively not over doing it. The kind of glue you use is important as well!

I would have liked to seen bayonet style in the caps with a small touch of glue and/or a snap fit. The inner workings could have used less tacky foam glue so the parts don't move but could be removed if needed (given the price it should be repairable).

Dan -

Not for the headphones themselves, but I guess the case could've been made a lot more repairable.

Christoph Parstorfer -

That was my first question as well. Compared to a lot of other consumer electronics, designing fully wireless earbuds that are easily recyclable would seem to be an interesting (and likely difficult) engineering challenge. Both in terms of the physical design as well as surviving even a rudimentary cost-benefit analysis. Going by the AirPods and Apple Pencil, it seems like glue is the cheap, easy go-to solution when the internal components aren't enough to justify a major recycling effort. Though the case itself might be worth recycling. I'd think that the glue also helps with a better seal as well, but it's not like these are water resistant in the first place.

Manual recycling looks like a total no-go for these. They could probably automate some of the breakdown (ugh), but again, the recoverable materials per item are so low it couldn't be justified economically. Unless Apple ate the costs as part of their marketing efforts, it looks like the AirPods themselves go straight to the landfill.

Tom S -

That's a good question, I can think of quite a few ways. Per example the metal connector base coud be used as a screw to hold the case together, and the internals could be kept in place in a sandwich like fashion by a plastic support. Everything would be tightly secured by the base screw, which could be unscrewed to open the case and grant access to the battery for replacement.

But Apple's engineers aren't really that much into clever internal product design, they're more about the finish, aesthetics and low manufacturing costs. Who cares about recycling when you can just use tape and glue. Leave the environment speech to marketing.

asuma -

Massive glue is used because it is needed for acoustic sealing around the housing and the transducer. No other ways like ultrasonic welding can replace glue in earbuds and headphones.

steve -

The same way watchmakers have done for centuries - captive spring-loaded pins locking a thread.

Kliment -

Samsung seems to have done it without a non-stop glue nightmare, so Apple should be able to, too.

Waiting on objective measures of the sound quality. Given how much they improved Macbook speakers, even the 12" beating many larger laptops, hopefully these didn't miss that love.

I think he is referring to what looks a little like tiny bubbles within each of the pads in the array (But I could be mistaken... an arrow would help a LOT!)

The chip utilizes a Ball Grid Array. (BGA) Each dot is a contact. To attach it to the board a special solder/flux ball is placed on each contact. The chip is then placed on the board by a robot and heated with air hot enough to melt the solder. When it works it will result in a nice solid connection. When it fails it won't. The problem is that many times it will work fine during testing and for a period of time after. Once the connection breaks then you will either get intermittent problems or sudden failure. A common do it yourself fix for a circuit board with a failed BGA chip connection is to put it in an oven at around 400 degrees for 5 to 10 minutes to remelt the solder. This was a common fix on the HP LJ 3005. To properly fix this problem the chip has to be removed from the board, the solder balls are removed and replaced with new ones and then re attached to the board and baked. This obviously will never happen on airpods as it would be more expensive to repair then to just scrap the entire device.

Any ideas what the gold ink is doing connecting the speaker grilles to the circuit?

"The cable weaves into an intricate speaker assembly that houses a proximity sensor and some antenna lines."

Maybe using the speaker grilles as antennae?

Any chance you could 3D print the housing in order to complete a repair?

Rob Link - 回复

Hyperthetically you could, but would be near impossible without a 3D scan of the internals of the housing to do so. You would also need to use a 3D printing technology that has a high resolution such as sla or Sls, which firstly comes with their inherent surface finishes, but secondly are quite pricey as processes (not something you print on a home printer). And then even if you get around those issues, you would then have to remove the existing components without further damaging them and assembling them in the correct order and then apply your own glue. It's all possible, but much better off spending your money on a new pair...

According to IPC-A-610 Rev. E chapter 8.3.12.4 "BGAs" 30% Voiding is okay. In very level. So normal industry standard. There is no solderpaste reflowing without voids. And voids are not automatically a problem. That is the reason why production and customer are allowed to negotiate a own border for that value. Head-In-Pillow-Defects were be a problem. But you have to lower the x-ray angle to see them. So from that Picture: Everything is fine for me.

Dan - 回复

I agree 100% about the acceptability of the voiding seen in the x-ray images of the reflowed BGA solder joints. Perfectly normal.

I'm actually more interesting in how the ear buds plastic housing component is made....it's seamless on the outside, yet houses a complex assembly inside. Injection moulding can't do this in one piece, and there is too much air inside to be over moulded. Maybe two pieces glued together then polished?

Brad stebbing - 回复

I would think the flashing is ground off and then the casings are polished up :)

Does ifixit do chip teardowns, or does anyone else for that matter ? Would like to understand the inner workings of the w1 chip in terms of sending and receiving signals and power saving methods.

Someone needs to tell Apple that ALL EARS are ANALOGUE - it doesn't matter how the sound gets up to the transducers, because they just turn it back into analogue sound pressure. What a fools errand all round.

Gives the fanboys something to spend money on and coo about, I suppose...

I am an Apple user, I love most of their products, but this is just utterly STUPID.

I have one perfectly working iPhone 5S, a perfectly working set of EarPods with Remote and Mic (and two more brand new, sealed, for spares) and I have ZERO intention of "upgrading" to anything "better". In fact, I'll shortly be going back to a Nokia 3510i I would think (no, I am not joking) because this obsession with a "central distraction hub" is shortening my attention span, STEALING my time and to be honest, it's all just overrated, non-vital guff that people have become seduced by for no good reason.

I would like to add a little resin to the earpods to improve the fit in my ears. The problems is they then won't fit in the housing to charge.

I'm interested in the charging contacts for the airpods. It looks like any 1.5v source would get them charging without a negotiation pin. Can you confirm that or is there some kind of 2-wire communication happening?

Also what do the contact points inside the charging case tubes look like? Are they just beryllium-copper springs? Are they spring loaded? Are there magnets to hold the airpods in?

Will - 回复

Why such a small battery? Weight or just space? I think they could have (and may well one day) double the size of the battery and double the battery life. Ten hours on a charge would be awesome.

From the pics, it looks like the antenna is just a thin flex stuck to the side of the battery. However, on the video it looks more like a flex on a 2mm ? substrate. Is this correct and if so, is the substrate plastic or ceramic ?

Hi Folks,

I'm pretty interesting how does apple earpods connects to between each earphone? Does it Bluetooth connection?

asimpl3ns - 回复

Yes, I think they use Bluetooth. I think your iPhone establishes a connection with each Airpod for music relay. The AirPods connect with each other to synchronize audio perfectly and do other stuff like that. At least that’s what I’d assume.

Liam Powell -

Like Brendan, I use the rubber ear hooks so that they fit into my ears better. I wanted to use a dremel to shave a bit out of the charging case where the airpods sit, and some also out of the cap of the charging case, so they will fit into the charging case with the rubber ear hooks still on. I was wondering if damage anything by doing this? Or will I just be removing plastic from the case, without any risk of cutting into something important? For instance, is there something in the cap to indicate to the iphone that the cap of the charging case has been opened?

Ron Schriner - 回复

After a bit of messing about with the case, I worked out how it knows if its closed or open. Its the little magnet at the front centre. If you leave the lid open, and your iPhone on, you can trick the case to think its open or closed by holding a magnet to the top middle just in front of the headphones.

So, yes, I think that making the gap for the top of the airpods bigger would be ok as long as you don't damage the LED or cable, plus keep the magnet working.

I'm going to try just leaving the lid open all the time and make a magnet attachment out of sugu that fits will to "close" the case to charge.

Tim - 回复

The AirPods sound OK by themselves but sound much better when pushed into your ear canal. I want to try one of the silicone sleeves but they obviously don’t fit into the case. I’m wondering if there is an easy (relatively speaking) way to remove the lid and replace it with one that would accommodate the larger profile. It would be nice to see some photos with a little more detail of the hinge mechanism. Has anyone built an accurate 3D model of the case? A surface model is probably good enough to work with.

Crazy question: How would one go about soldering a 3.5mm female headphone jack into the case? Any thoughts at all? I want to add a female headphone jack to the case in order to plug any music source, like a laptop with no bluetooth, into the airpod case via a 3.5mm male to male cable into the airpod case and hear it thru the airpods.

Notwithstanding the case damage to expose the electronics, does it appear that this would be possible at all? Or is all the bluetooth handled in the actual airpods themselves, negating the practicability of this idea?

Thanks for any productive answers, and bite my shiny mettle ass for any nonproductive ones.

Not possible, audio is streamed over BT from the device directly to the AirPods.

Buy a $5 bluetooth-USB adaptor off ebay… Airpods can work with bluetooth.

Weilai -

You can pair AirPods with any Bluetooth audio source, but the sound quality isn’t good. I paired them with my Surface Pro and it was downright atrocious, worse than any other Bluetooth I had tried. I suspected it was intentional to keep them in the Apple ecosystem. It also loses all other functionality, like the prox sensor and tap control.

If you must, get a USB Bluetooth dongle for the computer, or a universal 3.5mm AUX to Bluetooth adapter. But you might have better luck with a competitor’s earbuds; unless you are listening to them on an Apple device, they’re horrible.

Every cut out of the AirPods earphone is protected by a water restricting mesh. Same mesh is used in iPhones to make them water resistant. Find a video of EverythingApplePro on Youtube where Philip send AirPods for a complete cycle of washing machine. Do you want to know what happened? AirPods survived and were still in working condition.

So yes, there are no Water Indicators…

I seem to have bent one of the charging contacts in my case - only very slightly but apparently enough to not allow charging the pod anymore.

That sounds like a difficult prospect! If you’re out of warranty or just want to DIY: The tools that immediately come to mind are these thin probe tools.

After months of satisfactory use, my left one is putting out less audio than the right one. Audio quality is still fine.

Finding a lot of questions about ways to charge the airpods without a case. Knowing that the case provides is a 3.81V 1.52Wh cell, would it be possible just to hook up a power source (e.g., three AA batteries) to the contacts on the bottom of the airpods to charge them without the case? I’m not an EE, but could someone help me understand if this would work, and if not, what else needs to be considered? Thanks.

What would be the best (safest) place to drill 2 small holes for a tether?

My best guess from studying your excellent teardown would be the bottom corners… thoughts?

The intention here is to pass a small, high tensile strength string (like spider wire for ex) in, then out (essentially through) the casing, or, even a metal ring… Loosing these things is a real thing.

The case can send battery-status info to the iPhone when the lid is flipped open and held within a few inches of the phone — more than a few inches and it doesn't work. This sending status seems to work even if BlueTooth & Wi-FI are turned off. All this taken together seems to indicate it’s using NFC for this function. Know the iPhone has NFC (it’s used for ApplePay).

Does the W1 chip have imbedded NFC ?
