Headphone wire principle

Why is the wire so magical? How does the power cord work? Now we talk about the principle of wire working.

Is the enthusiastic wire really amazing? Older enthusiasts have practical experience in different equipment to match different wires, knowing that the sound of different enthusiastic wires is different. In the eyes of novice enthusiasts, I feel how magical these wires are or how these old-fashioned enthusiasts have an impeccable golden ear. But what many people can’t explain is why the power cord makes a crucial change to the sound, while others think that the power cord is a metaphysical. In fact, as long as you understand the principle of changing the wire to the sound, you will understand that this is not metaphysics.

First of all, the role of signal lines and speaker lines or headphone lines may be known in practical applications, but there are very few people who agree with the role of the power line. As we all know, the conduction of direct current and alternating current is different from the complex audio signal. The direct current and the relatively fixed frequency of the alternating current such as 220v 50hz are relatively simple and stable, and the frequency and strength of the audio signal. It is constantly changing! Therefore, the wire design for different purposes is different from the requirements for the type of conductor.

According to the Ampere theorem, we know that there is a magnetic field around the current. The conductor passes through the current, and a magnetic field is generated around it. The generated magnetic field will introduce the vibration and the vibration will interfere with the conduction of the current together with the magnetic field check. As discussed on the 52 hardware, coupled with changing frequencies and different signals, more complex magnetic fields and vibrations are generated, and external radiation and vibrations make the ideal conduction extremely complicated. .

The second is to understand the impact of the wire itself on the transmission. I use a simpler diagram to let everyone understand.

The resistance is expressed as the DC resistance when passing through the conductor, and the inductance produced by the conductor is the inductive reactance generated by the conductor itself. The distributed capacitance generated when the insulator is attached to the conductor is attached to the surface of the conductor. This value should be equal to 0, but it is not practical. More conductors are checked together to create capacitance and inductance. These capacitors and inductors exist between these conductors. When these conductors are considered as a whole or a conductor, they will exist in the whole. The shield is attached to the conductor to prevent EMI interference, but it also produces capacitance and inductance. In this complicated conduction process, in addition to being polluted by the outside world, its own structure and so on have a very large impact.

What you need to understand later is the effect of distributed capacitance and inductance on the sound. The size of the output coupling capacitor of the power amplifier will directly reflect the difference in sound. In the past, the coupling capacitor needs to be non-inductive, in order to reduce the influence of the inductance on the sound. This makes it easier to understand the influence of the capacitance and inductance of the conductor on the sound.

Finally, the skin effect is also considered as a key factor to be considered. Due to the physical characteristics, the signal in the high frequency band basically walks the conductor surface, and the low frequency signal travels in the middle of the conductor. At this time, the high and low frequency signals are not evenly distributed, causing an influence on the sound.
