The main function is that the main function is to form a symmetrical airflow when the speaker vibrates, improve sensitivity, and prevent dust and other debris from entering the magnetic circuit. The density, thickness, material, and size of the air intake of the paper film directly have a great impact on the sound. , is also a very important part of the headphone speaker tuning, making certain changes in the sound effect.

Airflow control: Everyone knows that the speaker is actually a conversion device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate, because the electrons The energy changes at any time, the coil of the speaker will move forward or backward, so the paper plate of the speaker will move accordingly, and this action will change the density of the air to produce sound.

In the earphone speaker, the sound requirements are very high. The tuning hole in the earphone unit is used to control the airflow introduced when the diaphragm vibrates. The size of the airflow directly affects the different degrees of sound; , thickness, and density to directly control the size of the airflow, thereby affecting the relaxation range of the diaphragm to control the sound, and directly achieve the effect of tuning.
