Disassembling report: pioneer pioneer I800 Lightning interface wired headphones

0 Comments

The old Japanese audio pioneer has been silent in the headset industry for a long time. As the saying goes, a sword is grinded for ten years. Every time the pioneer launched a new headset is a heavyweight product. The Pioneer Pioneer I800 launched this time is a in -ear active noise canceling headset designed for the Lighting interface.

This headset not only applies to the lossless Lightning digital audio output, but also uses a large circular unit. Their matching can bring better sound quality, and also supports active noise reduction headphones. Let’s disassemble this full -featured headset.

The headset body, the wire is the noodle line, and the two wires are divided into two wires to connect the left and right headphones through the wire control.

Noodle wire, flat and easy to store.

Lightning plug close -up.

The wire control part has noise reduction switch, volume adjustment button and playback button.

The back of the line control is the LOGO of Pioneer Pioneer, and the call microphone hole is next to it.

Next, look at the headset. It adopts a unique shape design. The middle diameter is relatively large and the ends are relatively small, because it has a built -in large -circulating unit, and this shape design is easy to get. Black shell and red wire.

There is a Pioneer logo on the laid -end plastic cover behind the headset.

Second, pioneer pioneer i800 disassemble

There is a hard plastic press.

The audio catheter of the headset is oval, which is a design of the contour of the human ear canal.

The shell on the plug is divided into a three -layer protective cover structure, a layer of soft silicon glue sleeve in the middle of the hard shell, and then the lower lower shell.

Because the plug is small, it is speculated that there is no audio chip in the plug.

There are laser carvings on both sides of the steel shell. This is a QR code, and the wire is welded on the PCB.

Disassemble the steel shell, with a sealing IC and capacitor.

Back capacitors are sealing.

Next, disassemble the wire control part, remove the keyboard from the keyboard, and then inside the keyboard of the motherboard.

Remove the bottom shell of the line control.

On the other hand is a metal grounded shift, near the tail side is a microphone.

The line -controlled microphone hole is written with a layer of dust from the inside.

With the backboard of the motherboard, the microphone hole corresponds to a hole of the motherboard.

Looking at the motherboard, there are four micro -motion keys and a MEMS silicone wheat.

On the other side of the motherboard, there is a chip and other IC covered by QR Code stickers.

Micro -motion button is specially written.

Disassemble the family portrait.

Third, my love audio network disassembly summary

1. Use the lightning plug. There are steel shells and multiple plastics at the plug. The wires use noodle wires to facilitate storage. The line control uses a metal shell. The headset is designed with a special shape. The round shell can reduce the collision;

2. Built -in LAM module, responsible for Lightning digital audio decoding output, built -in ANC active noise reduction module is responsible for active noise reduction function;

3. The headset uses a 10.6mm large -dimensional dynamic ring unit, and the built -in microphone of the earplugs is used to actively noise reduction function.
