How To Fix Laptop Speaker Crackling: Effective Solution
Repair of the speaker is one topic I get asked for most often. If you can’t hear anything from your laptop, usually the first thing people try is to find and remove the cover from their laptop’s speakers. And if you’re lucky enough, all there really is inside are a few wires that need to be connected again. Sometimes though it’s not that easy.
As I’m writing this article, my PC fans making noises as hell and my own netbook speakers are making strange cracking sounds every now and then while working with some music in the media player. So I decided to take a look at what’s happening under the hoods of the speakers on this little guy.
Before opening any component like this, disconnect your laptop from powerplants and wait for it to cool down. The speakers are usually accessible by removing the front cover of your laptop or netbook. Remove any screws in order to take off the grill and get access, here is a pic of my Acer Aspire One:
Once you removed all screws, check outside the speakers if there’s some kind of foam rubbers between them and anything else in your notebook (I’ve seen that in many cases) – remove every such obstacle carefully without damaging anything else surrounding the speaker membrane.
Try to do everything possible before handling the speaker itself; because once you do something with it, things might not go back as they did before. It will be safer if you’re able to re-connect the cables to the correct points.
Acer Aspire Speaker Crackling Fix
In this case with my Acer Aspire One’s speakers, all I had to do was clean them with compressed air. The problem was caused by dirty speaker membranes.
The cracking sound coming from the speakers is caused by dust particles between the membrane and the paper behind it doing static electricity. Just use some q-tip with alcohol or water and wipe the dust away.
After wiping clean the speaker membrane, just re-connect the cable and if needed change it’s position so as to prevent further furniture with your sound system.
If you do not want to work on a static electricity-prone surface (like the carpet), just hold a rubber or plastic insulated object while doing this job – like your screwdriver. Better find some earplugs when working with speakers too.
Once you reconnected all wires and cleaned up all dust form the speaker membranes, turn back on your device to check whether you’ve fixed any problems. If that is not enough, try using compressed air properly to blow away any remaining dust particles from between speaker membrane and paper below; but be careful not damaging anything in the process.
Your speakers should be working now
If nothing works for your laptop’s audio problems, it’s very likely the problem lies within the cable (wire) itself. It can get easily damaged while placing or moving your computer – especially if it comes from inside the netbook because most of them will have their cables sewed between two pieces of the plastic body of a netbook under big tension and strain while closing or opening the device.
Inside my Acer there are two cables for speakers connect to each other (the cables that go from the motherboard to the speaker). One of them was cracked open and it left a thin layer of plastic around the wire itself and when I tried re-connecting this cable, the casing just broke.
So what you need to do now is prepare some superglue adhesive and put glue around every crack in your speaker cable – be sure to cover every bit of exposed wires so they won’t touch anything with moving parts inside. After covering everything up with superglue all you have to do is wait until it dries out completely (around 15 minutes). After that, re-connect the cable and it should work.
Speaker Protection Guide
The cracking and popping noises could be avoided by using a sound wire to your PC instead of having longer cable from the built-in speakers – this is because longer audio cables are more sensitive to electrical interference.
Also you can get away with one single audio wire going out from your PC’s motherboard instead of connecting both left and right (stereo) channels together.
A great way to deal with audio crackling is to buy acoustic foam which should go over the loudspeaker on your laptop, but be careful if any metal part is exposed in the speaker area.
Just cut out the hole for that metal part not to touch any surface around it; then take some adhesive tape like 3M Tape or something like that and stick it onto the surface around your computer where you placed the foam. This will minimize or completely cut out any static electricity coming from your surrounding environment.
This is what I did in order to fix a lot of cracking noises coming from my speakers, but if you don’t have acoustic foam around just try doing something like this for better results:
Tape over your computers speaker with electrical tape (or whatever else you can find); put more tape over that area so as not to leave any part exposed; cover everything including the LEDs on top of each speaker. This should work better than using acoustic foam alone.
If after all these attempts still haven’t worked for you, it’s time to get more advanced in solving this problem by doing some soldering job.
