Computer has a murmur how to eliminate

　A, the computer itself has a murmur

Reason 1, computer motherboard there is no leakage.

Solution: With a wire, the wire metal at both ends of the metal exposed, one to the computer mainframe outside, not the key metal parts. Got to the ground. (Special note: Wiring in the computer outside the mainframe must not be selected in the key parts, pay attention to you and your computer security)

Reason 2, computer host accessories whether there is loose or improper installation.

Solution: Listen to the computer host is not sound abnormal (such as fan voice too large, not smooth operation, etc.) according to the situation, please professional cleaning or debugging.

Reason 3, if the computer has problems such as the need to clean up trash files, remove viruses, trojans and other computers will also appear murmur. Network jam, speed is not fast, also can cause sound abnormal.

Solution: Do a good job in computer maintenance. The speed is not enough sound should be easy to hear.

Second, the headset has a murmur

1, the inside of the headset loose, slightly moving the headset line will have a current sound, this situation if a little electrician, you can put the head back to weld it. No, it's better to send the repairs.

2. The magnet on the earphone horn sticks to the Tiemo or other sundries, this sundries presses between the magnet and the horn diaphragm, causes the diaphragm to contact with the magnet, emits the murmur, this question only has changed the horn.

3., the horn diaphragm due to the pressure of the diaphragm deformation, resulting in the horn diaphragm touching the magnet, emitting a murmur. It is recommended to use the mouth gently to the speaker with a murmur of inhalation and blow, you can repair minor deformation of the diaphragm.

　　Third, the microphone has a murmur

1, the microphone has a murmur, the first boils down to the music quality problem, some inferior sound itself contains the shrill effect of the murmur, you can choose to cancel to listen to this sound, and then choose to change other music can. As shown in the picture, replace the music in the music player.

2, may appear hardware failure, check whether the microphone is intact, whether there is a foreign body into which, whether the edge of the shaking paper has been peeling off, damage. If this happens you can repair the microphone or change the microphone.

3, also may be the circuit in the AC component is too large, this time is probably the Speaker power filter circuit has occurred, especially the filter capacitor. There is a power problem, may be caused by the power of the current sound, is a normal phenomenon.

4, microphone and computer connection between the host if there is a problem, then the microphone and computer connection to disconnect, and then reconnect correctly, and see if there is no contact bad phenomenon. This problem may occur when the microphone is in an enhanced state, just step away from the microphone because some sound card is not supported.

5, look around you have no magnetic field and with sound waves of material, such as mobile phones, fans and other equipment, with magnetic field of electrical equipment to solve this problem.

　　Four, the sound has the murmur

1, first check to see if the surrounding external environment is not good, wiring is intact.

2, check the computer's sound card driver whether there is a problem, you can reinstall again.

3, open the computer before the stereo inserted in the computer, because the computer when the current is large, easy to affect the sound of the film, so it is best to boot before connecting the computer.

4, adjust the computer above the volume control. Pull the microphone's mix volume to Bell.

5, look at whether the computer installed there are not suitable procedures, and see the computer's host parts are not loose.

6, in the state of the check sound, there are problems to repair shop to repair the stereo.
