The headset and the device is connected to the line connection (in addition to the connection and Bluetooth connection).
The sound unit of the headset is a moving coil unit (there are also moving iron unit headphones, coil-iron hybrid headphones, etc.).
Headphones with different transducers:
Moving coil
The sound unit is a round polyester diaphragm, coated with metal powder, and connected to an electromagnetic coil at the back. When energized, it is vibrated by the magnetic force to produce sound. Moving coil earbuds are characterized by the sound of feelings, listening to natural and easy, but the sound details and levels of poor, slow. Common models such as Sennheiser MX90, CX300, AKG K701.
Moving-iron
The principle is similar to the moving coil, is a very small piece of metal, to the S-type magnets in the connecting rod connected to the vibration force. Moving iron sound is characterized by fast sound, rich in detail, but the lack of emotion, the sound field is not natural, not very suitable for listening to music, because the moving iron type was originally used for hearing aids, and moving iron type unit due to the constraints of the principle of sound, can only be made into a closed in-ear type. Common models are WESTONE UM1, ETYMOTIC ER4, UE10 and so on.
Isomagnetic
The driver of isomagnetic headphones is similar to a scaled-down planar speaker, which embeds a flat voice coil into a thin diaphragm, like a printed circuit board, which allows for an even distribution of driving force. The magnets are concentrated on one or both sides of the diaphragm (push-pull) and the diaphragm vibrates in the magnetic field it creates. Isomagnet headphone diaphragm is not as light as the electrostatic headphone diaphragm, but has the same large vibration area and similar sound quality, it is not as efficient as moving coil headphones, not easy to drive.
Electrostatic
Electrostatic headphones have a light and thin diaphragm, polarized by a high DC voltage, polarization of the electrical energy required by the conversion of alternating current (AC), there are also battery-powered. Diaphragm suspended by two fixed metal plate (stator) formed in the electrostatic field, electrostatic headphones must use a special amplifier will be convulsed into hundreds of volts of audio signal voltage signal, drive, the sound pressure level that can be reached is not as large as a moving coil headphones, but it is a fast response time, able to replay a variety of tiny details, distortion is extremely low.
Electret
Electret headphones, also known as fixed electrostatic headphones, its diaphragm itself is polarized or polarized by the diaphragm outside the polarization of the material emitted by the electrostatic field polarization, do not need special equipment to provide polarization voltage. Electret headphones have most of the characteristics of electrostatic headphones, but the electret will gradually depolarize and need to be replaced, its life expectancy of about 5-10 years.
Question 2: moving coil headphones, moving iron headphones, electrostatic headphones, what is the meaning of the most intuitive expression is Generally speaking, the most high-grade large headphones are mostly electrostatic High-grade in-ear earbuds are mostly moving iron The most common headphones are moving coil
Question 3: the difference between moving coil headphones and moving iron headphones Most of the earbuds are moving coil, which has a block of diaphragm almost as big as the magnet
The most common headphones are moving coil.
The magnetism of the magnet and the size and quality of the diaphragm determines the sound convulsions
PX200 is a diaphragm. It has a larger unit. The benefits of a large headphone unit and a large speaker unit are the same
We said that the moving iron is generally in-ear, generally refers to the cavity can be very small
Moving iron is generally from the high-end to the low-end of the 1 unit, 2 units, 3 units, and so on
A unit can be very small very small...
You said the magnetism and diaphragm size quality determines the sound of the twitches.
What you said about the IE6 7 8 of the Sennhei, in fact, as a moving coil of the in-ear is not too small, the iron three CK1....
This is the technology ~
Moving coil benefits are .... Equivalent level is cheaper than the moving iron, but from the resolution and speed is not as good as the moving iron
Moving iron general entry at least 4,500. low-end are not quite perfect, I have a. The resolution and the middle and high sound can be as good as the mid-range. The resolution and midrange and high end can be compared to the mid-range moving coil. High-end moving iron is too expensive... I haven't tried it. But certainly... It's awesome
PS: Non-professional... Just look at it
Question 4: The difference in sound quality between double and single dynamic coil headphones. High frequency unit, and low-frequency unit made of different materials into a double moving coil will make the headset 3-frequency performance are excellent. Specifically manifested in the dynamic resolution, although it can not be compared with the moving iron, but for the single-dynamic is a great improvement. So in general, multi-dynamic coil than single dynamic coil hard quality! But the abruptness, hardness, unnaturalness, a certain frequency band turbidity and other problems also appeared. How to solve, depending on the manufacturer's crossover technology JVC double moving coil crossover using physical bass crossover tube crossover 3 moving coil to join the nano-crystalline crossover frequency impeccable moving iron did not do .... . JVC was the first to do, and then other manufacturers to follow suit. Anyway, the original model is not ideal. 2014 Audio-Technica CKR10 is said to be very amazing sound density texture, but also mixed reviews.
Question 5: moving iron earbuds and moving coil earbuds, what is the difference, which sound quality is good The two sound principle is different, generally speaking moving iron earbuds is fixed coil, through the ferromagnetic membrane vibration sound. Moving coil earplugs are fixed magnets, voice coil vibration in the magnetic gap after the electricity, driven by the vibration of the sound film and sound. Earplugs in the two sound quality is not absolutely good or bad, each model specifics need to be specifically analyzed, generally believe that the quality of the moving iron better sound cold, moving coil sense of music stronger sound warm, but this is not absolute, of course, the decisive factor is definitely listening to music. As if there is no strongest race, only the strongest players, the best equipment in the heart of each person.
Question 6: What is the concept of double-dynamic headphones The number of moving coil units is different
Whether there is a difference in style depends on the "tuning"
Question 7: What is the meaning of moving coil type ah? The word "coil" means coil, and the word "moving coil" means a moving coil. Moving coil type means that this type of headphones or speakers or microphone works by using the principle of the movement of energized coils in the magnetic field made.
Moving coil microphone as an example: moving coil microphone is made using the phenomenon of electromagnetic induction, when the sound waves make the metal diaphragm vibration, connected to the diaphragm on the coil (called the voice coil) along with the vibration, the voice coil in the magnetic field of the permanent magnets vibration (do cut the movement of the magnetic field of magnetic susceptibility), which produces an induced current (electrical signals), induced current size and direction changes, changes in amplitude and frequency determined by the sound waves, the signal signal current is generated. Frequency is determined by the sound waves, this signal current is amplified by the amplifier to the speaker, from the speaker on the amplified sound.
Question 8: What is the difference between moving-coil headphones and moving-iron headphones The difference between moving-coil and moving-iron units
1, the construction of moving-iron headphones
First of all, we need to figure out the difference between moving-iron and moving-coil construction principles. Sound process, moving iron earbuds and moving coil is actually similar to the basic, are relying on the voice coil in the permanent magnetic field vibration and sound. The biggest difference lies in the construction principle and location of the sound unit.
Inside the moving-iron earbuds, the voice coil is wound around a precision piece of iron in the center of the permanent magnetic field called the "balance armature". This piece of iron magnetically drives the diaphragm to produce sound. The moving coil drives the diaphragm directly, whereas the moving iron is conducted through a sophisticated connecting rod to the center of a miniature diaphragm, which vibrates and produces sound.
In terms of unit placement, traditional moving coil earbuds are unable to fit the entire articulating unit into the ear, whereas moving irons can easily fit into the ear canal due to the much smaller size of the unit. This effectively reduces the size of the in-ear portion of the device to fit deeper into the ear canal. Because the geometry of the ear canal is much simpler than the auricle, and belongs to the class of round so a soft texture of the silicone sleeve relative to the traditional earplugs has been able to play a good sound isolation and sound leakage effect.
The above is summarized from the little information I could find for the time being. Some of the articles on the web that introduce the moving iron have more mistakes, so I hope you pay attention to them. In fact, the construction principle of the moving iron is not very complex, but the manufacturing cost and the technology required is much higher than the moving coil. Why are the high-end earplugs mostly moving iron? This is about the advantages of moving iron.
2, moving iron has those advantages?
Moving iron sound insulation effect is better than moving coil into the ear. Due to the large area of the moving coil unit, and in the process of the sound needs to be called more space and air involved in vibration, and therefore can not effectively control the phenomenon of sound leakage; and moving iron can effectively reduce the area of the ear part, and can be put into the deeper part of the ear canal. (Almost all moving coil headphones have ventilation holes, while moving iron headphones have fewer ventilation holes, with the exception of the CK9.) Because the geometry of the ear canal is circular, much simpler than the auricle, a soft silicone sleeve can already provide good noise isolation and sound leakage protection compared to traditional earbuds.
The sensitivity of the moving iron is higher than the moving coil, mainly because the structure of the moving iron unit is almost a closed container structure, a little bit of a small current can drive it, pay attention to here, the relationship between sensitivity and resistance. It is because of the higher sensitivity, moving iron headphones transient performance is better, the dynamic performance of music, instantaneous detail performance, sound density is far better than moving coil earbuds.
The frequency response curve of moving-iron headphones is more stable. Moving coil headphones in different temperatures, humidity and the use of the process, the frequency response curve will appear some audible changes. Dynamic iron, on the other hand, shows good stability, making the sound quality more stable and reliable, not easy to change. A very important reason is that the moving iron unit is almost all made of metal materials, through the high precision mold forming, moving coil unit vibration diaphragm is generally through the glue and coil want to combine, so inside the influence of the elements are many, individual differences are more. So compared to the moving coil unit electroacoustic performance is much more stable.
Moving iron volume is more compact and lightweight. This is due to the characteristics of the moving-iron unit decided, moving-iron diaphragm weight with the increase in the diameter of the unit and straight up, so moving-iron used in the smaller volume of the in-ear earplugs will be more suitable for the earplugs, it is not possible to make an open or half-open earplugs. This is why moving-iron technology is now only used in in-ear earbuds.
Moving-iron headphones help protect your hearing. As mentioned earlier, moving-iron earbuds generally have good sound isolation, and the extremely high sensitivity makes it possible to have a good performance at very low volumes, so you don't have to increase the volume to enjoy pure sound in noisy environments. Moving iron units are widely used in medical, health care, aviation, military and other fields, the more common are hearing aids. Doctors will not recommend products that may harm the health of patients, and basically the more well-known brands of hearing aids are using moving iron units, so moving iron headphones are more assured than the use of moving coil headphones.
3. What determines the sound quality of a moving-iron headset?
The sound quality of earbuds is a cliché.
As we all know, the sound quality of moving coil headphones in the hardware mainly depends on the material of the diaphragm and the cavity material, construction, the magnet is mainly to determine the drive of the headset. The design of the cavity has a crucial role in the sound performance of moving coil headphones. From the above, we probably understand the basic structure of the moving iron, the moving iron earbuds to determine the quality of the sound of the parts and moving coil is obviously different.
First of all, the cavity of the moving-iron headphones has a small impact on the sound quality. This is one of the moving iron ...... >>
Question 9: headphones in the: turbo, moving iron, moving coil, what is the meaning of each ah Turbo is the name of the magic sound of a headset And I can not afford to buy the magic sound of the people because I said it is not good (off-topic) 。。。。。 The following content is my Baidu, because Baidu's more professional than I said
refers to the use of an electromagnet to generate an alternating magnetic field, the vibration part is a piece of iron suspended in front of the electromagnet, the signal passes through the electromagnet when the electromagnet will make the electromagnet magnetic field changes, so that the iron vibration of the headset sound. Inside a moving-iron headphone, the voice coil is wound around a precision piece of iron called a "balanced armature" located in the center of a permanent magnetic field. This piece of iron drives the diaphragm to produce sound under the action of magnetic force. The moving iron is conducted to the center of a miniature diaphragm by a precision-constructed connecting rod, which generates the vibrations that produce the sound.
The advantages are long life and high efficiency. The disadvantages are large distortion and narrow frequency response. Commonly used in early telephone handsets. Unlike general moving coil headphones, moving iron type of pronunciation unit can be made very small, so you can put 2 or even 3 units into each side of the sound channel, respectively responsible for the high and low sound and sound field processing. The sound effect can be comparable to advanced speaker systems
The following content is my own writing
In addition to the moving iron and static electricity, the rest are moving coil, that is, the general headphones are moving coil
In addition to pay attention to is the big headphones do not have a moving iron, only the earbuds have a moving iron earbuds in general, are a little bit more expensive than the moving coil ear buds, the moving iron is usually a high point of resolution of the moving coil to listen to the good feeling of the big headphones earbuds than the ear buds, the earbuds can not be used as the earbuds.
