Key factors affecting the sound quality of headsets

Although the living standards and material conditions have improved in recent years, moving coil driver unit headphones are still the mainstream for consumers. The same is the dynamic earplugs, What is the biggest difference between moving coil headphones? You should know the size that is closely related to headphones.


Although there are many factors that can affect the sound quality of the headphones, the soul of the dynamic headphones is a moving coil unit. How to measure a moving earplug is good or not? Compared with the material of the enamel, the author thinks that the size of the earphone unit is more important. why would you say so? Let us look at the sounding principle of dynamic headphones.


As the most common earphone structure, the principle of a dynamic earphone is similar to that of a normal speaker. The coil in the permanent magnetic field is connected to the diaphragm, and the coil drives the diaphragm to sound under the driving of the signal current. Due to the vibration of the diaphragm, the sound is more natural and relaxed, and has a natural frequency response range.


After understanding the working principle of dynamic headphones, we will find that when the same force acts on different sizes of speakers, large-sized speakers can achieve better low-frequency dive, better low-frequency looseness, and greater sound scale. And the sense of energy. At the same time, due to the limitation of the cavity space, the size of the unit of the general in-ear earphone is small. Because of the large size of the headphones, the size of the unit is generally large. Therefore, it is easy to understand why an experienced friend insists on selecting a larger unit size earphone.


However, with the exploration and familiarity of different materials, the advantages of cell size are being gradually brought closer by different material advantages and cavity structures. The appearance of bio-diaphragms, liquid crystal diaphragms and wood diaphragms enhances the physical properties of the diaphragm. In addition, the precision of the diaphragm processing technology enables metals such as titanium and tantalum to be uniformly distributed in the form of nano-molecules on the earphone diaphragm made of new materials such as polyester, which is enhanced from another level. The quality of the earphone diaphragm.


Starting from the first in-ear dynamic earphone A81, Feida uses the self-developed top-grade titanium polyester dynamic diaphragm to uniformly distribute titanium nanoparticles to ultra-thin nanometers according to the exclusive ratio and time combination at 230 °C. In the grade polyester film, the transient reaction is more agile than the ordinary diaphragm, and it is more flexible and elastic than the conventional titanium molecular coating. This technology is accompanied by the development of flying, and is reflected in different types of moving coil/ring iron earplugs, which lays a material foundation for Feidu’s pursuit of high definition and high reducing power.


Small size earphone diaphragms in both material and technical aspects, the frequency response range is significantly improved compared to the previous ones, and with the help of 3D software, the cavity structure can be further designed and calculated. Today’s in-ear headphones Can have better performance in sound performance. The ability to drive an in-ear dynamic earphone with new materials, innovative technology and high-quality cavity design is as good as some headphones.


Whether it is the flagship of the flying ancestor model but the dynamic ring earphone A81, or the latest flagship ring iron earphone Sirius Sirius, there is a lot of work in the cavity design. The in-depth exploration of the cavity structure, combined with the high-quality unit design, has enabled Fly to gradually challenge the flagship headset. We also hope that more friends can listen to the latest flagship iron earphone Sirius through various channels and feel our uniqueness in materials, craftsmanship and design.


The emergence of new materials and new processes has made the current unit size not a decisive factor affecting the sound quality of headphones. However, in terms of the sounding principle of moving-coil headphones, large-sized units do have advantages when the spatial structure allows and is appropriate. Whether it is an in-ear earphone or a headphone, combined with factors such as impedance and sensitivity, it is easier to obtain high-quality sound by selecting a larger unit size earphone.
