Reasons that affect the sound

There are usually two reasons that affect the sound effect:

1. Line problems.

If the contact is not firm, then the motherboard leakage will cause the circuit to mix in other voltages and currents. The most primitive and effective solution is to add a capacitor to absorb interference, but this requires professional operation;

2. Interference of electric and magnetic fields.

Sometimes electric and magnetic fields can also affect the sound of computers, such as microphones, mobile phones, magnets, communication base stations, and satellites. The most primitive and effective method is to place a completely enclosed wire mesh on the sound shell, so that the wire mesh forming the loop forms an electrostatic shield. In this way, all electromagnetic interference from the sound itself can be shielded.
