With the improvement of living standards and material conditions in recent years, consumer single-movement unit design is still the mainstream. Is this decisive factor affecting the sound quality of headphones still so important in the past? The performance of dynamic headphones is significantly affected by the size of the unit.
As the most common headphone structure, the principle of dynamic headphones is similar to that of ordinary speakers. The coil in the permanent magnetic field is connected to the diaphragm, and the coil drives the diaphragm to make 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 advantage.
After understanding the working principle of dynamic headphones, we will find that when the same force is applied to speakers of different sizes, large-size speakers can achieve better low-frequency dive, better low-frequency looseness, and larger sound scale. And a sense of energy. At the same time, due to the limitation of cavity space, the unit size of general in-ear headphones is relatively small. However, due to the large size of the headset, the unit size is generally larger. Therefore, it is easy to understand why experienced friends will insist on choosing headphones with a larger unit size.
However, with the exploration and familiarization of different materials, the advantages of unit size are gradually being narrowed by the advantages of different materials and cavity structures. The emergence of biological diaphragms, liquid crystal diaphragms and wooden diaphragms has improved the physical properties of the diaphragms. In addition, the refinement of the diaphragm processing technology allows metals such as titanium and beryllium to be evenly distributed in the form of nano-molecules on the earphone diaphragm made of new materials such as polyester, which has improved from another level. The quality of the earphone diaphragm.
In terms of material and technology, the small-size earphone diaphragm has a significantly improved frequency response range compared to the previous one. With the aid of 3D software, the cavity structure can be more in-depth design and calculations. Today’s in-ear earphones Can have a better performance in sound performance. It can drive an in-ear dynamic headset that uses new materials, innovative technology and excellent cavity design, and its playback effect is no less than that of some headsets.
With the emergence of new materials and new technologies, the size of the current unit is not a decisive factor affecting the sound quality of headphones. However, in terms of the sounding principle of dynamic earphones, if the space structure allows and is appropriate, large-size units do have advantages. Whether it is an in-ear earphone or a headphone, it is easier to get excellent sound by considering impedance, sensitivity and other factors comprehensively, choosing a larger unit size earphone.
