1. What is the hole in the earphone used for?
 
If you are careful enough, you can find that in addition to the sound hole on the earphone, there are often a few small holes in the back. What are these holes 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.
 
These tuning holes are made up of tuning nets and tuning cotton, so don't use sharp objects to chop these holes for curiosity, otherwise your headphones may be scrapped...
 
In addition, the tuning hole can also be used to identify the true and false headphones, such as holding these holes while listening to songs, if the music has not changed, then your headphones should be cottage.
