All equipment tends to fail sooner or later. It seems that the speakers are practically new, but gradually a strange noise is heard more and more clearly. At first it seems that this is just a temporary phenomenon, but every day the noise becomes more intense and soon it is impossible to make out the sounds coming from the speakers.
Instructions
Step 1
There are many sources of noise generation. The most annoying thing is when the noise in speakers or TV comes from a ringing mobile phone. In this case, getting rid of the noise in the speakers is quite difficult, but you can attenuate it. To do this, it is necessary to neutralize the magnetic field of the heads using shielding. First of all, you should replace the plug with which the speakers are connected to the computer or music center. It is better if the plug is in a metal case. You need to inspect the signal wire that leads from the speakers to the computer. Each wire must be individually or double shielded.
Step 2
It is also necessary to replace all the old wires with shielded ones inside the speakers. It is better to move the power filter inside the column. Then you should purchase a shielding paint and a brush from a building supermarket, disassemble each column, carefully paint it with paint and let it dry for several hours. If it is not possible to purchase paint, ordinary aluminum foil will help solve the problem. She needs to glue all existing columns from the inside. After these simple but time-consuming procedures, the noise will not appear at all, or it will be insignificant.
Step 3
If after connecting the speakers, in one of which there is an amplifier, there are slight noises when the wires or the mouse move, grounding is required. If there is a grounding, the problem may be in a poor-quality power supply. A change in current consumption occurs during the movement of optical and magnetic heads, scrolling text and other actions. The drive motors need more current, the processor has to redraw fragments from the screen in response to the movement of the scrolling motor, which causes current surges and changes in power consumption.
Step 4
It is possible to suppress this interference only with proper wiring of power circuits, installation of a high-quality power supply and blocking capacitors. The sound and system board is responsible for blocking and wiring, but the power supply plays the main role. The problem can be resolved by replacing the power supply.
