However, did you ever notice that there are several very important holes in this pair of headphones?
Today, Wilson and Bibi is going to reveal the use of these holes for everyone!
Some people think that the role of the small hole is to reduce noise, and some people think that it is designed to leak a certain frequency of sound. No, they all got it wrong!
The role of the small hole is actually...
The function of the earphone is originally a Mini sound system that can be placed in the ear. The current will push the diaphragm inside of the earphone to push the air to make a sound. However, if the internal vibration of the earphone drives the air to flow, the air pressure inside will rise. After the rise, the resistance of the vibration of the diaphragm increases, causing the headphones to be squeaky and not crisp enough.
This is a problem with many inferior headphones, so Iphone has a small hole on both sides of the earphone to balance the air pressure inside and outside of the earphone, making the diaphragm vibration more flexible and the sound is more crisp! We’d tried it ourselves. The level of the song is more delicate than other headphones, and the sounds of various instruments are heard clearly.
Therefore, these small holes are actually the "venting holes" of the earphones. If you accidentally block them, then it would be a huge disaster for your ears!
Also, these small holes are also an effective way to check if the headphones are genuine! The hole in the pirated Iphone headset has no effect. If your Iphone headset has no obvious sound quality changes after blocking the hole, it is definitely a fake Apple earphone!
If you use this headset, remember to check if there is any dust in the hole, or it will hinder the air in and out! It turns out that a small hole has so many functions as well.
