I know if you have noticed that in addition to the sound hole, the earphones delivered by the mobile phone usually have other small holes. These small holes may seem inconspicuous, but they actually play a big role!
As we all know, a small speaker is built in the earphone. The speaker works through the resonance of the earphone cone and the electromagnet to send sound waves into the air to produce sound. The cavity structure of the earphone is a completely enclosed design except for the sound outlet. The vibration of the body will also increase the pressure inside the headset, which in turn hinders the vibration of the speaker.
Therefore, these small holes are needed at this time. The small holes allow air to flow in and out of the speaker, which not only prevents pressure accumulation, allows the earphone speakers to move more freely, but also creates better sound quality and heavy bass. Effect.
Therefore, these small holes are also called "tuning holes", and they exist to make the music more beautiful. However, opening small holes is also very particular, so just digging a hole is not enough. Tuning nets and tuning cotton are often attached to the inside of the tuning hole to adjust the sound more accurately.
If there is no tuning net and tuning cotton, the sound will become muddy. So don't use a sharp object to poke the small hole on the earphone because of curiosity, otherwise your earphone will be ruined...
In addition, tell everyone a little trick, try to press the small hole on the earphone with your fingers vigorously when listening to the song, if the music does not sound changed, congratulations, your earphone should be a copycat.
