This also makes the traditional 3.5 interface headphones not directly used on the iPhone 7 and subsequent models, but in the iPhone 7 to iPhone X are randomly distributed a Lightning to 3.5 short-term, to use the old headphones, or third-party headphones.

In the near future, Apple is newiPadThe 3.5mm headphone jack and Lightning interface were removed from the Pro and changed to the USB Type-C interface. This interface can both charge and transfer data. What's more special is that it can also output digital audio, so the new iPad Pro comes with a USB-C to 3.5mm headphone jack converter, and this converter There is also a single item retail version.

Below I love the audio network to lead everyone to see how the two lines are different in appearance.

Putting the USB-C to 3.5mm headphone jack converter together with the Lightning interface converter shows that the two are very similar.

The size of Lightning and USB-C interfaces is significantly different, and USB-C is wider and longer in size.

The Lightning interface is compared to the USB-C interface shape.

The size and length of the two 3.5mm headphone holes tend to be the same.

In order to facilitate the memory, we will first show it through the table to see the interface usage of Apple's recent products.

It can be seen that basically the recently launched computer products and the latest iPad use the USB-C interface, while the mobile phone and the old iPad use the Lightning interface. This line is still widely used in Apple's own products, but do not know if they will have much difference in sound quality, thrust and other performance? I love the audio network will be unveiled by everyone.

First, Lightning, USB-C to 3.5mm adapter cable

1, Lightning to Headphone Jack Adapter Appearance Analysis

According to my love audio network, Lightning to 3.5mm adapter, about 10cm, is about the same length as a normal business card.

3.5mm interface section.

According to my love audio network measurement, the Apple Apple Lightning to 3.5mm Audio adapter cable has a wire diameter of 2mm.

Lightning turns to 3.5mm wire and the plug surface is smooth.

The middle line has a laser engraving, made in China, model A1749.

According to my love audio network analysis, the Lightning position can be magnetically sucked, and the round mouth does not suck.

The same interface as charging.

3.5mm socket inner hole, according to my love audio network analysis, the internal is copper nickel-plated contact points, connected to the 3.5mm interface headphones feel good.

The iPhone 7 began to remove the 3.5mm audio interface of the body, with Lightning to 3.5mm patch cord and Lightning EarPods headset.

The front of the package is a rendering of the patch cord. The top is the product name: USB-C to Headphone Jack adapter cable. The name of Apple's official website is USB-C to 3.5 mm headphone jack converter.

On the back of the package are the USB-C to Headphone Jack extension cable in English, French, German, Italian, Spanish and Japanese.

Packing list: user manual and warranty, 1 USB-C to 3.5 mm headphone jack converter.

At first glance, it looks very much like the previous Lightning patch cord, which is also embedded in the paper tray. Due to environmental considerations, the product packaging is mainly paper.

The overall close-up of the USB-C to 3.5mm headphone jack converter is printed on the wire with the model A2049. The wire material is soft and similar to the EarPods wired headset.

This USB-C interface is not a full-pin USB-C.

Second, Lightning, USB-C to 3.5mm adapter cable disassembly

Lightning turns to 3.5mm wire and the plug surface is smooth.

Take the Lightning head apart.

Inside is a metal cover.

On the other hand, there are 5 solder joints on both sides. The solder joint process is very solid and meticulous. Apple style, so I found a line of words.

The macro shot is closer, and the DLC63572YX5HDPWAP line is clearly seen.

The metal cover is opened, and the inside is filled with glue and hard rubber.

According to my love audio network dismantling, I found that this is not an ordinary adapter. After all the disassembly, I saw PCB and multiple chips.

There is a layer of glue on the chip.

A small PCB integrates multiple components.

On the other hand, I vaguely see a larger chip.

This is a lot of wires that are soldered onto the PCB.

The glue is scraped off and the chip is not very clear.

From another angle, the black one is 11G and the lower right is 6YF.

The other side of the big chip is 338S00140 / A0QK1623 // TW

The chip is shiny.

This position can be seen clearly in the above words. According to my analysis of the audio network, the "33xxxxxxx" numbering chip has always been designed by CirrusLogic for the iPhone. It is a highly integrated single chip, including Apple encryption, USB Controller and Codec on one chip, so this chip is responsible for major functions such as digital-to-analog conversion.

At 3.5mm, cut the casing and weld multiple wires inside.

Another angle.

Lightning to 3.5 is completely disassembled.

The overall close-up of the USB-C to 3.5mm headphone jack converter is printed on the wire with the model A2049. The wire material is soft and similar to the EarPods wired headset.

Start dismantling, USB-C head welding is very strong, dense spot welding, we take the USB-C head apart.

Inside is a metal cover, the metal cover is removed, and a PCB can be seen.

The wire is soldered to the PCB and then sealed with a glue.

After simply cleaning a layer of glue on the PCB, you see a shiny chip.

Cirrus Logic Lingyun Logic, 46L06-CWZR, is a highly integrated chip that includes functions such as USB Controller, DAC and headphone amplifier, so this patch cord can be seen as a complete USB sound card.

Cut off the wire and you can see that there are multiple capacitors at the end.

Cut the sleeve and socket on the side of the 3.5mm socket and you can see that multiple wires are soldered to the socket terminals.

I love the audio network with a 1 yuan coin for size comparison, you can see that the entire plug assembly is very small.

Third, I love the audio network disassembly summary

1. Both adapters use Cirrus Logic's audio chip, built-in DAC and headphone amplifier, and the difference is MFi chip and USB controller;

2, the work of the two lines are very good, the input plug is covered with metal cover for dense spot welding, the strength is guaranteed, and the inside is sealed with glue;

3. At the end of the 3.5mm plug, there is not much difference.
