The headset is small and exquisite and does not take up space, but there is a situation that annoys many people. It is the earphone cable that is neatly stored. As long as it is not put in a special storage box, the earphone cable will be messy and entangled when you take it out next time.
Things that seem more incredible can be solved by science. The headphone cable does entangle itself, why does this happen? Let’s look at the raw materials of the headphone cable. The inside of the earphone is generally made of metal wire made of thermoplastic material. Everyone knows that metal wires are generally prone to bending. In situations where the length and width ratio of the earphone cable is seriously unbalanced, it is more likely to bend. Sometimes the plastic of the earphone skin is accidentally broken, and it is often found that the wire itself has been twisted and bent.
The headphone cable generally has two forks on it, so that it is convenient for two ears to use the headphone at the same time. However, the two separated thin wires will also be entangled with each other due to the unbalanced force of the metal wires. If you put the earphones in your pocket at will, it will be troublesome. Even the main line will cause the three lines to become a mess.
The knotted entanglement of the headphone cord attracted the attention of researchers. They found that when the length of the headphone cord is 46 to 150 cm, knotting and twisting are most likely to occur. When the line length exceeds 150 cm, the probability of knotting is relatively small. When the line length is less than 40 cm, knotting will not occur. The length of the headphone cable we usually use is basically about 140 cm, because this length can ensure that people of different heights can easily use the headphones.
Usually we put earphones in our pockets. Our body will shake when riding in a car or walking. At this time, the earphone cable is in an active state, and the earphone cable itself wants to maintain a stable internal structure, so we can only choose Winding. By increasing the friction between the earphone cord and the pocket, it is used to offset the influence of the outside world. The general situation is that the greater the amount of personal activity, the more knots will be entangled.
In response to this situation, many businesses have introduced small boxes for linear headphones. In this way, the headphone cable is not prone to knotting or tangling. Why? The headphone cord is entangled back and forth, another condition is needed, that is, enough space. The small box space for earphones is relatively small. In a small space, the headphone cords are tightly attached, and there is no room for stretching.
Through the above description, we know the principle and space requirements of the headphone cable knotting and winding. If you don’t want your headphone cable to be knotted and wound, then reduce the storage space, or choose a thicker headphone cable to reduce the knotting and entanglement.
