How to get on the Apple 5S triangle iron sheet, what is the use of the triangle iron sheet in the Ap

One: Sound quality audition:

Apple is touting the sound quality of its headphones and the admiration of its fans, and the results are really disappointing when you listen to them. The sound is a little bigger, and the dynamics are a little bigger, but the low frequency is not deep, elastic, and plump enough, the middle frequency is not soft and beautiful enough, the sound is a bit hard, the clarity is not enough, the details cannot be revealed, the high-frequency sound is very loud, but a little harsh, and the high-bass connection is not good. The sound quality of this kind of headphones can be done by people who have no level, and it can be said that they don't understand what sound quality is.

Two: the single speaker after disassembly:

1.Diaphragm and voice coil:

The diaphragm is made of composite materials, which is in line with the acoustic high and low pitch design concept, but I dare not agree that the best materials are used to make the most garbage sound quality. There is no advantage to the copper wire and caliber for the voice coil, and the advantage is that there is no need to mark the lead glue, which is due to the soft material used for the edge of the diaphragm, but the lack of lead glue does not mean that the sound quality is good.

2.Basin frame and magnetic circuit part:

The U cup design is easy to see that you don't understand acoustics at all, here the U cup is directly coupled with the plastic of the basin rack, there are multiple gaps, which must be done by people in terms of structure and machinery, as for what kind of acoustic adverse consequences will be won't say much. Also, this can also be seen from the iron sheet that replaces the PCB board, which considers the structural aspect and the acoustics do not understand at all, and the iron sheet that replaces the PCB board is to a certain extent to reduce the process, but it does not mean that the sound quality is good. The design of washer and magnet is not professional at first glance, and its basin frame has many aspects that have a negative impact on acoustics.

Three: the headphone cavity after disassembly:

It took a lot of effort to debug the earphone cavity, especially the back cavity, and used a very complex structure to debug, but in fact, I don't understand the sound quality tuning and acoustics at all, that is, I did it in vain, so I won't say much about the specifics. There is also the front cavity of the earphone appearance of the so-called modeling design, the front cavity of the earphone sound part is put on the side, with two circular holes outside the addition of an iron mesh paste, the front of the speaker also leaves a breathable hole, if it is the appearance of nonsense is reasonable, but if the acoustic piece is nonsense, from the side sound then the sound wave in front of the speaker radiation to the front plastic and then reflected back, in which there is a cavity between the speaker and the front plastic, so repeated acoustic interference, In short, it is not worth talking about at all about acoustic design.

From this earphone, it can be seen that Apple's headphones are only in appearance, and the process mold is also very good, but the sound quality is not worth talking about at all, Apple is just very good at fooling the so-called fruit fans in terms of marketing. Although this Apple 5S earbuds Apple earPods are better than the Apple 4S last time, this sound quality is not worth mentioning at all, it can only be a sound quality level that does not enter the stream.

Is it iron, it could be a motherboard gasket.

It doesn't matter if the battery is used for stationary use, and it doesn't matter much if it falls off. Specifically, it is not clear to put it in **.

Attach the small iron piece of the 5S fingerprint cable, disassemble the mobile phone first, and prepare a pair of tweezers; The specific steps are as follows:

1. Disassemble the phone first.

2. Prepare a pair of tweezers.

3. Insert one tip of the tweezers under the small piece of iron.

4. Pick up the small piece of iron upwards and pinch it to disassemble it.

5. Clamp the new one directly with tweezers and press it down to install it.

There are two dots in front of the iron sheet cover. Align the two holes underneath, and then attach them with a light tap of a camera or something. Be careful, though. Don't break the cables.
