Headset wire to determine the quality of headset sound quality reasons

Is it beats by dre sale really amazing to have a fever Veteran enthusiasts have practical experience in different equipment to match the different wire, know the sound of different fever wire is not the same. In the eyes of the cheerleaders who think that these wires are how the magic or how these veteran enthusiasts have a pair of impeccable golden ears. But many people can not explain why the power cord will make a vital change in the sound, and some believe that the power line is a metaphysics. In fact, as long as you understand the principle of wire changes to the sound you will understand that this is not metaphysics.

First of all, the signal line and the speaker line or the role of the headset line we may have in the practical application of the understanding, but the role of the power cord for the recognition of the few people. We all know that the conduction of DC current and AC current and the complex audio signal is not the same, the DC current and relative fixed frequency AC current such as 220v 50hz frequency and intensity is relatively simple and stable, and the audio signal frequency and strength But it is constantly changing! So the use of different wire design and conductor type requirements are not the same.

Middle school physics textbooks talk about the amperite theorem, know there is a magnetic field around the current, the conductor through the current, the surrounding will produce a magnetic field, the resulting magnetic field will introduce the vibration and cheap beats by dr dre vibration will be checked with the magnetic field interference current conduction. As discussed on the 52th hardware, coupled with changing frequencies and signals of different strength, beats by dre it produces more complex magnetic fields and vibrations, and more radiant and vibrating, making the ideal conduction extremely complex The

The second is to understand the impact of the wire itself to the transmission. I use a relatively simple map to let everyone understand.

The resistance is expressed as the DC resistance through the conductor, the inductance produced by the conductor is a sense of the conductor itself. The distributed capacitance of the insulator pack attached to the conductor adheres to the surface of the conductor, which should be equal to zero, but is not practically possible. More conductors are checked together to produce capacitors and inductors that exist between these conductors, and when these conductors are treated as a whole, a conductor is present in the whole. Shielding layer attached to the conductor, to prevent EMI interference, but he will have the same capacitance and inductance, such a complex process of conduction, in addition to outside pollution, its own structure and so on the impact is very large.

And then need to understand is the distribution of capacitance and inductance on the sound of the impact. Amplifier output coupling capacitor size will be directly reflected in the different sound, the previous coupling capacitor needs no sense, is to reduce the impact of the inductor on the sound, the reason is cheap beats headphones more easy to understand the conductor capacitance inductance on the impact of the sound.

Finally, the skin effect is also taken as a key factor to be taken into account, due to the physical characteristics of the high-frequency signal basically take the conductor surface, low-frequency signal to walk the middle of the conductor, then high and low frequency signal transmission is not uniform, resulting in the impact of sound.
