The difference between the internal small unit of moving iron vs moving coil headphones

Earplugs have now become a very common listening device. Whether you are in the subway or on the bus or in the mall, you can see the earphones listening to music, and with the development of the overall industry of earphones, the quality of the earphone products and itself. The performance of the sound has also become one of the focuses of users. The entry-level earphone products can not meet the people's pursuit of high-quality sound, but people have encountered many problems when buying high-end earplugs!

High-end earplugs mean high-end prices, and few people will not hesitate to buy a thousand-dollar earplugs. After all, when people buy high-end earplugs, they want to see the luxurious appearance and high quality of high-end earplugs. In addition, the sound performance of the earplugs is also very important. If you want to get a good sound, the earplug unit is very important. Now the earphone unit on the market can be divided into two types: the moving coil unit and the moving iron unit. What is the difference between these two units?

In fact, no matter in the construction principle, unit position and sound presentation, these two earplugs still have a lot of differences worthy of discussion. Some people say that the sound of moving earplugs is warm, the sound of moving iron earplugs is cold, although there is a certain truth. However, this is only a more general division between the two units. In particular, there are various minor differences between the two different units.

Let's take a more introductory point of view to explain to friends what are the differences between the two units, to see the big difference brought by the small unit, so that friends can better choose the earplug products that suit them. Also let friends better understand the mystery of the earplug unit.

First of all, let's take a look at the earplug products of the most common moving coil unit on the market. This type of earplug unit with a range of tens of thousands to tens of yuan can be seen everywhere. We don’t introduce the movements here for our friends. The difference between the circle units is to illuminate the circle unit itself. The moving coil unit is simply a production cost, but the unit that pays great attention to the processing level depends entirely on the quality of the sound.

Dynamic headphones are also the most common form of headphones we have, not just headphones. Most of the speakers are also moving coils. Its drive unit is actually a small dynamic speaker. The coil in the permanent magnetic field is connected to the diaphragm, and the voice coil drives the diaphragm to emit sound under the driving of the signal current.

Compared with the moving iron, the dynamic earplugs have various advantages and quality advantages, but one of the most important and fundamental advantages: the sound of the dynamic earplugs is closer to the natural sound, although perhaps the moving circle There is no high-precision and high-frequency tri-frequency as accurate as the moving iron earplugs, but the high-low dynamics brought by the high-end dynamic coils cannot be achieved by the moving iron.

For the earplugs of the moving iron unit, there are many classic examples. As the earliest earplugs for sale, the ER4 has been as brilliant as the one just listed in the past 20 years, with extremely high resolution and crystal clear sound. Make it have countless fans.

What is the moving iron unit? From the simplest point, it is the unit used by the previous hearing aid. It uses an electromagnet to generate an alternating magnetic field. The part of the vibration is a piece of iron suspended in front of the electromagnet. When the signal passes through the electromagnet, it will The magnetic field of the magnet is changed, so that the patch vibrates to emit sound. The unit of the moving iron can be made small, so that a plurality of units can be placed in each of the ear shells, which is commonly known as unit 2. , 3 units, 4 units and other multi-unit moving iron headphones.

In terms of unit position, the traditional moving earplugs cannot put the entire sounding unit into the ear, and the moving iron type can be easily placed in the ear canal because the unit is much smaller. This effectively reduces the area of ​​the ear portion. Can be placed in the deeper part of the ear canal. Because the geometry of the ear canal is much simpler than the auricle, it belongs to the round shape, so a soft silicone sleeve can have good sound insulation and leakage prevention effect compared with the traditional earplug.

In the development of multi-units, there are also many excellent examples. Shure's E5C and Weston's UN2 are both representatives of the two units. In the three-unit camp, Shure SE535, UE's TF10, Visa The UM3X and Westone3, both as representatives of the three units, also have excellent performance.

In terms of sound alone, there is still a big difference between moving iron and moving earplugs. For example, the structure of the moving iron unit is almost a closed container, which requires only a small current to drive it, so the sensitivity is also Moving iron headphones are more dominant. The resolution has always been a good advantage for moving iron headphones, and it is excellent for the playback of sound details. The universal moving-coil headphones are not so good in the details.

Compared with the moving iron, the dynamic earplugs have various advantages and quality advantages, but one of the most important and fundamental advantages: the sound of the dynamic earplugs is closer to the natural sound, although perhaps the moving circle There is no high-precision and high-frequency tri-frequency as accurate as the moving iron earplugs, but the high-low dynamics brought by the high-end dynamic coils cannot be achieved by the moving iron.

Due to the complicated manufacturing process and high cost, the moving iron unit has always been difficult for many people to accept. Even the cheapest moving iron headphones have to be several hundred yuan, which is not easy to popularize in the past few years. The reason. The cheapest dynamic headphones can even be bought for a few dollars, which is a different day. However, in recent years, the price of moving iron headphones is gradually decreasing, and with the increasing number of enthusiasts, this kind of The situation has gradually changed.

We have seen the difference between moving coils and moving iron earplugs, but many people are asking if there are earplugs that combine these two units. What kind of player should be matched with the sound after the combination? Can you better listen to the earbuds of these two different units?

In fact, the earphone products that combine these two units have been with us for a long time. For example, the K3003 launched by AKG is one of the representatives, but the price is always the hardness of this earplug, but this kind of movement The combination of iron and moving coil not only ensures the dynamic feeling of the moving coil, but also ensures the analysis of the moving iron. If the price is not considered, it can be said to be a perfect solution.

In addition to the earbud itself, the player is also a thing we need to mention briefly here. To better hear the good sound, a portable player must not be less, such as Sony's classic D50. A very powerful player with high resolution and density, can make up for the insufficiency of dynamic earplugs.

The iPod Classic can meet the needs of users with the action of moving iron earplugs. Its almost no noise and excellent thrust with warm sound can make up for the too cold feeling of moving iron earplugs, which is why many old burns. One of the reasons for choosing iPod Classic when you have a fever.

Finally, let's make a simple summary. We introduced the difference between the moving coil and the moving iron unit earplugs for the friends. Although we can't clearly say which one is better or not, I believe that through our introduction friends. We can better understand the different performances of these two units, and the choice will be more relaxed. It should be noted that many of the above are theoretical, but the real sound is good and bad. Everyone’s ears have different listening feelings. There is also a big difference, so listening to yourself is the best way to judge whether the earbud unit is good or bad. The one that suits you is the best sound.
