How to apply and install ferrite rings on audio lines

First of all, know the working frequency of your cable, and the wire warp, and then use a certain specification.

You can also choose the type t. You need to wrap the thread twice, but this premise is that your thread is not exposed, because it is not pretty.

There is also a kind of UF, a buckle magnetic ring, which is more expensive and is not recommended.

Hello! It's a peer, we are a manufacturer of power cords, I don't know how to apply ferrite rings in audio wires, I don't know very well, I helped you find it, there is the information you need, and I'll give you the reference address below. Next, I will tell you how to install, we generally wear the ferrite magnetic ring through the ** beam, and then injection molding, you said that the ferrite magnetic ring should be installed on the audio line should also be like this!

The electromagnetic waves radiated and leaked by electronic equipment not only seriously interfere with the normal operation of other electronic equipment, but also cause equipment dysfunction, transmission errors, and threaten human health and safety, which is very harmful. Therefore, reducing electromagnetic interference (EMI) in electronic devices is already a must consideration.

Absorbing magnetic rings, also known as ferrite magnetic rings, referred to as magnetic rings. It is a commonly used anti-interference component in electronic circuits, which has a good suppression effect on high-frequency noise, and is generally made of ferrite material (MN ZN).

The magnetic ring has different impedance characteristics at different frequencies, generally the impedance is very small at low frequency, and when the signal frequency increases, the impedance of the magnetic ring increases sharply.

As we all know, the higher the signal frequency, the easier it is to radiate out (to buy a high-quality computer case is also to reduce electromagnetic leakage), and the general signal line is without a shielding layer, then these signal lines become a very good antenna, receive a variety of messy high-frequency signals in the surrounding environment, and these signals are superimposed on the signal originally transmitted, and even change the original transmission of useful signals. Then, under the action of the magnetic ring, the normal and useful signals can pass through well, and the passage of high-frequency interference signals can be well suppressed, and the cost is low.

It is mainly used to filter out high-frequency clutter and spike signals, and to purify power or electronic signals.

We also use this, called nickel-zinc ferrite rings, which are used in our wiring harnesses.

Small on the transmission lineCylindersIt can block and reduce high-frequency noise and noise in the circuitElectromagnetic interferencephenomenon appeared. Generally, there will be a small black cylinder on the transmission line or power cable of the TV, laptop and other equipment. <>

The name of the small cylinder is calledFerriteMagnetic rings. Its raw materials are strontium oxide, barium oxide and iron oxide.

Compared with other permanent magnets, ferrite rings have the advantage of being stronger, and the magnetic energy is lower, and it will not easily demagnetize and corrode. The production process of making ferrite magnetic rings is very simple and the cost is relatively low, so the output of ferrite magnetic rings is the highest in the magnet industry, and it has a wide range of applications. <>

One of the main functions of ferrite magnetic rings is to block electromagnetic interference, so that high-frequency noise and noise in the circuit can be suppressed. Electromagnetic interference is very common in life, for example, when watching TV, standing next to the TV and playing **, at this time the TV will emit a squeaky noise, which is electromagnetic interference. Then the installation of a ferrite magnetic ring on the transmission line can reduce the phenomenon of electromagnetic interference.

Ferrite in a ferrite ringMagnetic permeabilityThe higher it is, the greater the impedance of the high frequency. Therefore, when the signal frequency of the equipment is relatively high, there will be a variety of very messy high-frequency signals, at this time, the ferrite magnetic ring can play a role, and the printed high-frequency interference signal can pass through, so that the signal can be used normally. The cost of the ferrite magnetic ring is relatively low, and the effect is relatively good, so its existence can be seen in the transmission line of many equipment, so that the signal on the equipment can be normal and stable.

Because these small cylinders can block noise and undesirable noise, thus ensuring the normal operation of the transmission line circuit. You can often see this kind of thing in our power cords.

The small cylinder on the transmission line, in fact, is very large, in addition to stabilizing the transmission line, the biggest role is anti-interference, so that the data you transmit will not be lost, this design is very ingenious.

Generally, there is this small cylinder on the transmission line of 3C electrons, which is generally anti-interference and anti-noise.

There is no magnetism, I opened it and saw that it was actually just an internal cable sparing a circle, in order to cancel out the inductive signals (self-inductance and mutual inductance) generated by the high-frequency signals in the two wires in each other.

How can it be. One is that the inductive reactance increases with frequency. Second, permeability varies with frequency. The cut-off frequency of 1000m is almost past the cut-off frequency. Broadband can't reach that high frequencies either.

Loss? I don't understand what the landlord wants to ask.

Although our company is doing magnetic rings.

It's also a little brother's professional knowledge.
