What is the hole in the earphone used for?

In fact, these small holes are very popular. They have a name called "tuning hole". Yes, it is used to adjust the sound.
Everyone knows that the reason why headphones can sound is because the built-in speaker makes sound waves into the air to make sound through the resonance of the earphones and electromagnets. The cavity structure of the earphone is completely closed except for the sound outlet, so that the vibration of the vertebral body will increase the pressure inside the earphone, which in turn will hinder the vibration of the speaker.
This time you need the tuning hole to work. The tuning hole allows air to flow freely through the speaker, which not only prevents pressure build-up, but also creates better sound quality and bass.

What is the difference between L and R for Cheap in ear earphones?
As we all know, the headphones will be divided into two channels, L and R. L is "left"; that is, the left channel, R is "right", is the right channel, but do you know why it is so?

If you wear it for a long time, your ears will feel uncomfortable and affect the listening experience.
Secondly, when people make music, they usually use two microphones to record the sound according to the left and right channels, which ensures the high reproducibility of the playback.

If you listen to the song without dividing the left and right channels, you will not be able to enjoy the most beautiful sound quality.
Finally, people need to distinguish the space, level and direction of the sound source through the left and right ears, and the left and right channels of the headphones also play a similar role. Especially when playing games with headphones, the player can correctly perceive the position of the other party through the left and right channels of the headphones, thereby improving the authenticity and experience of the game.
Why are the earphone cables entangled in a group?
In fact, this is because the headphone cable consists of thermoplastic elastomer and wire, which is very soft in itself, and the length and width ratios are easily out of tune, so the headphone cable is very unstable. In addition, when the headphone cable is carried around, the inertia may also cause swaying, which makes the headphone cord more easily entangled into a ball.
To solve this dilemma, you can use a little trick.
First fix the earbuds with your thumb and forefinger, then wrap the earphone cord around the index finger and the little finger in a figure of eight. Wait until the earphone cable has a small portion, then tie the previous earphone cable along the middle of the figure eight, and finally the earphone. The end of the thread is worn in the figure eight and tightened.
This is not afraid that the headphone cable is always entangled into a ball, and the next time you use it, just pull the end of the headphone cable and spread it easily, it is very convenient.
