Senior music enthusiasts generally have their own unique insights when choosing which headphones and music, and it doesn't seem to be affected too much by others. The average user does not have too high a requirement, just a headset can be used. The main entangled in the choice of what kind of headphones friends are generally first-time users, they have a certain understanding of the headset knowledge, but still not very rich, and the types of listening are not many, no comparison of various headphones, can not Determine if some of the headphones are really good, but always want to raise your listening standards, so there will be problems of one kind or another.
Regarding these friends, the entry-level headphones seem to be unable to satisfy them. They need better headphones to meet their listening needs, but they have encountered many questions. After all, it takes a certain price to buy headphones. Some. In the field of high-end portable earplugs, not only have dynamic headphones, but also iron earplugs are very good choices. For many people, it is heard, but always want to understand about dynamic headphones and Which is better for moving iron headphones, I believe that there are not a few friends who have such doubts.
We are trying to introduce some differences between the dynamic earphones and the moving iron earplugs from a relatively introductory level. They are all necessary to provide some necessary help when purchasing headphones.
In fact, there are many types of headphones, which are divided into different types according to different ways. In fact, for many non-headphone enthusiasts, they may not know that there are so many categories of headphones, but for the headphone fans, these categories are The mind is more clear. For example, according to the way of switching, there are two types of moving coils and moving iron headphones that we can often see at the moment. Perhaps you don't pay much attention. Most of the headphones we use are moving coils.
Dynamic headphones are also the most common form of headphones we have, not just headphones, but all of them are mostly moving coils. Its drive unit is actually a small dynamic ring 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.
The structure of the moving circle does not have much complicated place. It is relatively easy to make, and the technology is now mature. It has the characteristics of first model, wide frequency response and small distortion. Whether it is high-end headphones or entry-level products, earbuds or head-mounted, dynamic headphones are absolutely mainstream, because the dynamic headphones are not limited by the unit area, the diaphragm size can be larger, in theory, Get better sound, but due to other factors such as production technology and tuning, this is not absolute.
The headphones of the moving coil unit have a better sense of sound performance, the three-frequency connection is smooth, the sound field is more relaxed and natural, and the listening sound is good, which is what most enthusiasts know, and is keen on dynamic headphones. . However, the moving coil response speed is slow. When the dynamic earphone converts the electrical signal into a magnetic signal, it pushes the moving coil to emit sound waves. In the middle, there will inevitably be a little distortion, so the details are relatively less accurate, but it is relatively accurate. Better bass performance, so the sound performance will be warmer.
The moving iron headset is not really a new technology. It was used in the earphones of the telephone at the earliest time. It was widely used by hearing aids. It has only gradually been applied to music listening earplugs in the past decade. It does not sound the same as the diaphragm of the dynamic earphone. The voice coil inside the moving iron earplug is wound around a piece of iron in the center of the permanent magnetic field called the balance armature. This armature is actually the moving iron unit. The armature is driven by the action of magnetic force.
It uses an electromagnet to generate an alternating magnetic field. The part of the vibration is an iron piece suspended in front of the electromagnet. When the signal passes through the electromagnet, the magnetic field of the magnet changes, and the piece vibrates to make a sound. The moving iron unit can be made very small, so it is possible to put a plurality of units into each of the ear shells, which is commonly referred to as a moving unit of 2 units, 3 units, 4 units and the like.
The moving iron earphones are more efficient, so the response speed is very fast, and the playback of the details is excellent. It is very good at expressing the details and layering of the sound. However, the sound lacks music, the tone is cold, not so warm, lacks certain emotion and momentum; the frequency response range of moving iron earplugs is also narrow, but because the sound unit is very small, it is used in multiple units. The crossover line can be improved in sound and the frequency response range is also widened.
Because of the limitation of the principle of sound generation, the moving iron earphone can only be designed as a closed structure, and it is impossible for the earplug to be made into an open type and a head-mounted type. The production cost of moving iron headphones is relatively high, and it has not become the mainstream listening product for mass users. However, due to the many advantages of moving iron headphones, it has always been a pet of niche music enthusiasts. However, with the increasing popularity of music listening and the pursuit of high-quality sound, more and more people are paying attention to moving iron headphones.
So from the above we can easily see the difference between moving iron headphones and dynamic headphones, but they may be slightly abstract when they are introduced separately, not so intuitive, so we will take the iron headphones with dynamic headphones below. Compared with what are the advantages and disadvantages to make it easier for everyone to understand the difference between these two headphones.
Sensitivity: The structure of the moving iron unit is almost a closed container. It only needs a small current to drive it, so the sensitivity is also more dominant in moving iron headphones.
Acoustic music: Pu film thinks that the dynamic headphones have a better sense of music, while the sound of the moving iron headphones is cold and tough, but the mellow and smooth, the real moving iron headphones have this problem, making the emotional performance of the sound is not so prominent .
Sound field: Since the moving iron headphones are closed structure, the performance on the momentum has always been a defect. The dynamic structure earphones are excellent in this respect, especially the high-end open dynamic headphones are undoubtedly possessing an absolute advantage.
Resolution: Resolving power has always been a good advantage for moving iron headphones, and it is excellent for playback of sound details. The universal moving-structure earphones are not so good in the control of the details.
Layering: The moving iron earphone itself has a rich and detailed sound, and its layering distribution is also clear, and it does not have a smooth and excessive feeling like a dynamic earphone.
Sound density: The sound density of the dynamic headphones is slightly loose and not compact enough, and the moving iron headphones are obviously much stronger than this, and the compactness is very good.
Frequency response speed: The vibration efficiency of the moving iron earphone is high, so the corresponding speed is faster than the dynamic earphone, and the transient performance is also relatively fast.
Frequency response range: The narrow frequency response range has always been the soft rib of the moving iron earphone. The good moving coil structure earphone can even break through the listening range of the human ear to reach a wider frequency response range. However, moving iron headphones can compensate for some of the defects in the frequency response range by cell stacking and frequency division techniques.
Frequency response curve: The unit of the dynamic earphone is combined with glue and coil. During the different temperature and humidity and during use, the frequency response curve will change. The moving iron unit is made of metal material, which has better stability and sound quality.
Sound insulation: The dynamic earphones have a large unit area and require more space and air to participate in the vibration process, so excellent sound insulation cannot be guaranteed. The moving iron earphone can effectively reduce the area of ​​the ear part, and can be placed in the ear canal part of the deep root, so the soundproof effect is naturally more dominant. The good noise reduction performance of good soundproof headphones can reach tens of decibels, which is unmatched by dynamic headphones.
Volume: The characteristics of the moving iron unit make the moving iron earphones only have an earbud structure, and the volume is very small, and even a very small dynamic ring earphone is difficult to achieve the volume of the single unit moving iron earphone.
Price: 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. This is not the case in previous years. The reason for easy popularity. The cheapest dynamic headphones can be bought for a few dollars, which is a different day. However, the price of moving iron headphones has gradually declined in recent years, and with the increasing number of enthusiasts, this situation has gradually changed.
Of course, if you think that the above text is too boring, we have created a more intuitive form for everyone to watch, although it may not be as comprehensive as the text, but want to be faster in a faster way. The following table is useful for understanding the differences between the two headsets.
It is worth mentioning that the brand already has the perfect combination of these two modes of conversion. The combination of moving iron and moving coil combines the advantages of the two earplugs to ensure the dynamic sense of the moving coil. The analysis of the moving iron is undoubtedly perfect, and the AKG K3003 is such a revolutionary representative. However, the earplugs of tens of thousands of yuan are also top-notch in the earplug products, not the price that most people can afford, but perhaps in the near future, the earplugs combined with the advantages of this kind of iron and iron will gradually mature and the cost will decline. We are very much looking forward to it.
