Autumn has come, dear readers, Apple is releasing new products. And this means that specialists iFixit it’s time to blow away dust from the instruments that has settled on them since the day the MacBook Pro’s Retina display was destroyed. The most interesting is yet to come, but, let’s say, the headphones Earpods went on sale immediately after the presentation and are ready to be the first to go under the knife.
EarPods Model Number. MD827:
The new remote control with three buttons and a microphone (on the left) does not look like the remote control from the previous generation headphones. The wires above and below are much better protected from kinks.
Looking at the next photo, you will say that Apple removed the microphone hole in the remote control. and you will be wrong! The fact is that holes in general did not have. The round lattice was purely informative in nature. so you know where to talk. Now it is replaced by a microphone icon. Save on matches, Johnny?
To open the remote control, it is best to use a pick. Surprisingly useful when dismantling equipment.
The remote control consists of five components: two plastic covers on top and bottom, an elastic band with buttons, a flexible board, as well as an elongated metal plate. Here we see the top cover in the right hand, while everything else is still assembled in the left hand:
Remote control, rear view. That’s just in the plate (it is needed to stiffen) the hole for the microphone there is.
On the flexible board, in addition to the microphone, another microcircuit was found. Pathos Chipworks believe that this is either an analog-to-digital converter, or some kind of device for adjusting the volume.
Remote control fee (on top. dime, 10 cents coin):
Red. microphone 2F17 045;
Orange. TI25ASGVI 079.
Compared to the new remote, the old one is just a toy. Incidentally, it is much worse protected from moisture.
With the remote control over, it’s time to pick up a scalpel and go directly to the headphones. Earpods glued together, there are no latches. If you open at home (why it’s better not to do this, read below), then for re-assembly you will need fresh glue.
. modestly. Like most in-ear headphones (“drop”), one EarPod contains a membrane, voice coil and magnet.
The membrane. which is very important. is for the first time paper, not plastic. iFixit write that it will positively affect the low and medium frequencies. Body? From the inside, he no longer seems somehow supernatural.
So again: a magnet (left), a membrane and voice coil (right). And then they are the same, but upside down. On the outside of the acoustic design (around the magnet), a fine mesh is laid directly over the symmetrical holes.
This is an important component, because in order to maintain the required sound quality, the acoustic design must be rigid and open, so as not to impede the passage of air behind the vibrating membrane.
Mesh was not in the old headphones. From top to bottom: previous-generation headphones, earphones from the first iPod and EarPods.
IFixit is focused on durability, and EarPods are very good at this. But before us is an acoustic device, which, having been disassembled and reassembled again even with very great care, will never sound as before. Therefore, the assessment for the “ease of repair” will not. Till will not, because iFixit is just warming up. Very soon, iPhone 5 will lie on their table, then there will be iPod touch and nano, and then, you look, and the iPad mini will arrive in time.
