欢迎来到另一轮拆除对决!本周,我们介绍了两个手表的故事。
No, we’re not pitting a 42mm Apple Watch against a 38mm Apple Watch; what’s the point of that? Instead, this showdown is between a real apple watch and afake一。
再次查看图片:这些手表中只有一张是真正的交易!您能说出哪个真实的照片?
这是我们对参赛者的了解:
There are a lot of fake Apple watches available for purchase in Shenzhen; I’d like to think we picked a pretty good one. These knock-off magicians did a great job with the top side appearance; it could fool someone from a moderate distance!
当您翻转手表时,伪装散落的地方。假Apple Watch仍然依靠物理接触销来充电,而真正的Apple Watch则由归纳收取。
我们以同样的方式打开了两个手表:通过将它们加热高科技设备to loosen adhesives and prying their screens off with a sharp blade.
It was a lot easier to pry the screen off the Fake Apple Watch. The aluminum case on the Fake Apple Watch is soft and feels like regular Al-6061; it was no match for my trusty Leatherman.
但是,真正的Apple Watch Case明显更加困难,并进行了相当大的战斗。苹果宣传其自定义合金比标准合金强60%。我们怀疑它与7000系列铝相当。
We could also tell that the Fake Apple Watch’s screen was held on with formerly liquid adhesive.
In contrast, the Real Apple Watch’s screen is attached by pressure-sensitive adhesive tape.
And we’re in!
Display Module Comparison
Let’s look at the screens first. It’s quite obvious that the Real Apple Watch has a lot more going on.
The Fake Apple Watch has a fairly standard LCD—it’s the kind of LCD screen you used to find on old iPhones. The build quality is awful; all of these layers peeled off without any effort on our part.
In contrast, the Real Apple Watch features technology that you only find in high-end electronics. The flexible OLED display is super thin and makes traditional LCD screens look outdated.
力触摸传感器实质上是屏幕和外壳之间的垫圈,由环形柔性电路板(FPC)制成。那两个小手臂曾经固定在连接器上 - 我得到了将它们撕下来的停靠点。
Fake Apple Watch Internal Components
假Apple Watch的肠道被钣金支架隐藏在我们身上。实际上,它是在下面的金属老板上焊接的。不过,撬开这件事并不需要太多。
Now, we can see both watches’ organs side-by-side. The Fake Apple Watch was quite possibly designed by someone who had never seen the inside of a real Apple Watch—there are no similarities!
The Fake Apple Watch’s PCB is small, but it’s not crazy miniaturized. It has a MediaTEK ARM processor, and the battery has a capacity of 100mAh. Silkscreen markings indicate that this was made in July 2015, just a few months after the Real Apple Watch started shipping.
Here, you can see the FPC that holds the heart rate sensor and internal charging contacts. It’s impressive that there is even a heart rate sensor; that’s real attention to detail. We tried this feature before the teardown and minutes after, but my heart rate still didn’t produce a reading.
Here’s the vibrating disk motor. This is a very common component used in prototyping; if you have a project that needs some haptic feedback, you can get one fromAdafruit.
当您旋转时,数字冠实际上不起作用。这只是一个荣耀的按钮。O形圈将其保留给案件。
The buttons are CNC aluminum with an elastomer soft backing.
The side buttons’ switches are on the same PFC, tacked onto a plastic bracket with pressure-sensitive adhesive. Notice that one of the dome switches has a piece of masking tape over it. Hey, if your button top isn’t hitting the switch, just add some more material!
The watch strap release has twosnap-fit cantilever arms;Tiny Springs将它们返回位置。
皮带释放组件实际上是塑料的,涂有金属涂层以匹配铝制外壳。
将塑料后盖与铝制外壳分开,花了很多力量。使用的胶水量令人印象深刻。用于充电的铜触点和连接充电器的磁铁也粘在后盖中。
Now, let’s take a look at the Real Apple Watch’s internal components!
真正的Apple Watch内部组件
The battery in the 38mm Apple Watch has 205mAh of capacity. The Real Apple Watch’s battery volume is almost the same as the Fake Apple Watch’s, but it has twice as much capacity. Apple magic!
Extra component bonus: The Real Apple Watch has a diagnostics/programming flex board tucked into one of the side walls.
这是真正的Apple Watch的扬声器,不是全范围的Prima Donna,但肯定比假苹果手表所拥有的任何东西都要好。
The Taptic Engine is one of the most interesting components in the Apple Watch. In iPhones, we’ve seen rectangular-and disc-shaped LRA (linear resonant actuators) motors give way to cylindrical ERM (eccentric rotating mass) motors.
Taptic Engine是下一代的触觉反馈组件。在Apple Watch首次亮相后,它进入了iPhone,iPad和MacBook。
The Taptic Engine is a custom-designed electromagnetic linear actuator. Electric current passes through copper windings, which generates magnetic force. This magnetic force moves permanent magnetic masses along a center rod.
The side button switch and its mounting bracket are attached to the button top by a screw. The engineers can really dial in the tactile feel in this configuration.
The side button assembly itself is an intricate multi-part assembly. The complication comes from the need to prevent water ingress at a moving interface.
它的工作原理:按下按钮顶部时,它会轻推一个小圆柱体,然后将圆顶按钮开关在手表外壳的内部。同时,固定支架永远不会移动,其O形圈在手表盒上形成紧密的密封。
注意,这些微小的精密金属部件aren’t for mere mortals’ BOM budgets. The stationary bracket part is zinc, formed by metal注射成型(MIM)。按钮顶部可能是MIM铝。
The digital crown’s shaft is wrapped in O-rings, again to prevent water ingress. The sleeve bearing is the secret behind the amazingly smooth turn feel. The sleeve bearing is welded to a bracket on the inside of the case.
Here’s one more look at the button flex assembly. The Digital Crown’s tactile switch is on the left.
The Apple Watch has both Bluetooth and WiFi connectivity. Here’s its antenna, tucked into the twelve o’clock sidewall.
We didn’t find a conventional-looking main PCBA inside the Apple Watch, because that would be boring. The Apple Watch is powered by苹果S1, a “System in a Package”, also known as a circuit board completely encased in resin.
S1脱落后,我们终于可以看到心率传感器板和后盖。LED和传感器组件的大小使在假Apple Watch和其他腕部可穿戴设备上发现的LED接收器对相形见war。
复合封底中只有一个磁铁。您可以看到使用多少胶将其固定到案例上。
Showdown result
Was anyone actually rooting for the Fake Apple Watch? If so, we’re sorry—there wasn’t even a contest. From the quality of the charging method, to the sophistication of the electronics, to the materials used, the Real Apple Watch totally obliterated the pretender.
To be fair, the Fake Apple Watch is actually not a bad piece of hardware. It’s got all the building blocks that make up a typical wrist wearable. A semi-experienced, two-person ME+EE team could put this type of thing together, but interestingly, a lot of crowdfunded wearable projects never even get this far, so we’ll give the designers and manufacturers credit for effort.
真正的Apple Watch是由大型专家工程师团队设计的,并建立在疯狂的高级设备上,因此此时它属于自己的一类。它需要一座研发现金来建造像Apple Watch一样真正推动信封的东西。我们总是可以指望苹果向我们展示通往未来的道路。
