It's possible that there is a problem with the speaker itself that is causing it to produce a buzzing sound. Some common issues that can cause this type of problem include:
A loose or damaged speaker cone, which can cause the speaker to vibrate excessively and produce a buzzing sound.
A problem with the amplifier or other electronic components of the speaker system, which can cause the speaker to produce distorted or irregular sound.
Physical damage to the speaker, such as a crack in the enclosure or a dent in the cone.
In order to fix the problem, you may need to have the speaker repaired by a professional or purchase a new speaker. It is also possible that the problem is not with the speaker itself, but with another component of your audio setup (such as the amplifier or the source device). In this case, you may need to troubleshoot and fix the problem with that component.
Refit the rubber, you can find itbon eBay, its called reconing actually in this case the cone is the inlybpart wich you dont want to replace... The rattling is beingproducer due to the fact the rubber normally holds the cone ibto positionering over the coils. This rattling is not good can defect your cone. So dont play it roll you got a new rubber fitted!
Yep, if it is a scratchy sort of sound, the units coil has overheated, the voice coils insulation has bubbled and expanded, and is now rubbing against the magnet as it moves. Only fix is to replace the driver. U can confirm by moving the inner circle of the cone in and out of the magnet. Should not rub and be perfectly centered around the magnet.
A vibration sort of sound can be caused by loose screws holding down the driver. But that is usually the case on your large heavy drivers with large excursions, not a mid range speaker.
Is the sound coming from the speakers? (do you hear it with the sound turned off)
Either an audio problem if heard only with sound up or if a buzz with sound off it is a coil or transformer on the circuit board vibrating hard enough to produce the noise.
Both are fixable but require different tactics to resolve.
In older tvs the buzzing sound usualy comes from the HT lead plugged into the tube .open the back and switch the tv on (do not touch anyware near the set the HT lead carries avery high voltage even when the set is off)if u do see arching then u need to clean around the rubber of the ht lead )u can leave the set unplugged for a couple of days to allow the tube to discharge before attempting to clean around it.
1st of all
click on start->programs-> Accessories->Entertainment->Volume control->options->properties->select Microphone->then click on Mute on microphone.
hope this will work
Not from the speakers? Check the bezel around the radio. If it feels loose, it may be causing your buzzing sound. The cure is to get some small strips of sticky foam and cut squares big enough to go around the tabs. This should quiet it down for you.
I have this problem with my 37LG30. They all seem to have the same factory flaw. The plastic bezel and rear is vibrating against itself I have found. Tonight, just now, I just took all the front bezel screws out,(from the back) loosened the other 4 big screws in the rear center(I don't recommend removing them)and loosened the stand screws also and tried separating the bezel from the back as I went around the set. This did not really help much except around the bottom where the noise/vibrating comes from-the speaker area. The two plastic pieces are vibrating against one another. The vibrating was coming from the speaker area without doubt. The next thing was to try separating at the bottom where the speakers are with my fingers and a stiff metal nail file carefully..fingers seemed to work best for me. As I separated the front bezel from the rear housing (at the speaker location)most if not all the buzzing/vibrating /distortion went away. I then inserted small pieces of cotton (you can use felt, or similar I suppose) and buttoned it all back up;put the screws in Almost all the distortion and speaker buzz/vibratingis gone except on very low frequencies. good luck!
I suspect that what you are hearing is the 60 cps of the mains. If the humming sound is coming the subwoofer itself, then it is possible that you have a defective/leaky capacitor in the power supply section of the subwoofer. In the subwoofer, if the buzzing sound is coming from anywhere else other than the speaker itself, then it is possible that you have a loose transformer again in the power supply. Unless you are comfortable working with testers and soldering irons, I would suggest an electronics technician who should be able to diagnose and fix it for you.
