VLC damaged my laptop speaker

[ahmed_unreal]

just installed VLC PLAYER guys on my laptop "DELL" and used it for sometime , few days back my media player got crashed . anyway i had to use VLC PLAYER , i listen to hard metal so i raised the sound to 200% , well the sound was great after just 15 minutes or something , i heard strong noise from the left speaker , i thought something is wrong with the software but no sire , my speaker is spoiled 😀 , the VLC got my laptop speaker dead , i just want to ask the creator of this program , does he have any idea how hard it's gonna be in a place like this to fix my laptop and how the hell i am gonna get the spare part i need , i am crying people this sucks for sure , i know what u probably gonna say it's dell 's problem but VLC had to tell me the risk or anything , anything that could tell me this was gonna happened i don't understand how could such app be available to download and u something if u raise it to %200 u gonna get ur self only bad sound

guys , last thing does it have to be replaced , can't i just fix it or something 🙁

When the incoming signal from the audio source is particularly loud, it will overdrive the amplifier. This causes the amp to "clip" or distort, and that sound is passed to the speakers. Not only does this cause the amplifier to overheat and wear out more quickly, but the loud-level high harmonics in the distortion can destroy the speaker. This can occur even if the amp is underpowered for the speakers when the gain is too high.

Oh great , I will record a video called "this will blow your speakers" , edit it to 5000% audio gain , upload it and have fun then ! On second thought people are idiots sometimes and they already tried it ..... it DIDNT WORK .... 😛 That's because distortion or clipping , will move the wattage to less than double , so every manufacturer drives his speaker with a less than half amp . Therefore no blown speaker . A 5 watt amp cant blow an 11 watt speaker . Even in a worst case scenario . If the manufacturer is stupid enough to not follow this simple rule .... he should RMA them .

Clipping is a common cause of blown tweeters. They are basically square waves instead of sine waves.

In the case of under-powering, the driver is blown because the amplifier is driven to the point that it can no longer amplify the signal. The amp tries to generate the amplified version of the input waveform, but runs out of "headroom" before the full wave is generated. The result is a square wave. The sinusoidal version of the waveform is only partially generated and the result is a square wave with a "plateau" on the top. The "plateau" is pretty much a DC current at that point. DC in large enough amounts or long enough times is what burns up speakers.

The driver is only driven part of the way in or out, but it is held in a suspended position at the top of the square wave the amp is generating. The result is the speaker is in a near DC state and the constant voltage without any corresponding movement causes the windings of the voice coil to heat up. Eventually the heat is too great for the windings and they burn up.

I just asked my six year old niece what would happen if turned a speaker up twice as loud as it's meant to go.

She said it will blow up.

She has more common sense [strike]then[/strike] than you.

Why do you think it's hard to fix it? Where do you live?

Why do you think it's hard to fix it? Where do you live?

Hi

Its NOT hard to fix, its the expensive labour.. we would charge in the UK a minimum of 1 hours labour (£50) plus the new speaker to strip the laptop and solder in a new speaker...

OR you could just plug in a decent set of speakers to the audio jack and blow your ears off that way...at 200%

All the best Brett

Jag - well done on the clipping explanation. I used to sell stereos part time in the 80s - had more people blow their 400W Cerwin-Vegas with a cheap under powered amplifier.

BTW StefanGR - you do not know what you are talking about.

Many 100Watt speakers have been blown by a 50 W Amp - when it clips.
Speakers are impedances - the have a nominal impedance from 20-20,000Hz of 4-8Ohms. When clipping occurs short bursts of DC(direct current - 0Hz) go through your speakers. Dc resistance may be fractions of an OHM. Very high currents will flow through the voice coils making them very hot - will burn the enamel off the copper wire.

No offence, but that was completely your fault. You should know that 200% is well above what you should put the volume up to. Common sense.

ah , well and it's not VLC 's fault at all to damage ur speaker after only 15 minutes if it was wrong then why did they put such option from first place without even a notice

The option is there due to different average volume results in encoding. It's far preferable audio quality wise to increase the source by 20% or 100% vs your amplifier having to be set 20% over normal.

I actually believe this is an especially useful setting I use regularly that should be in all players. If my wife and I are watching a video on my laptop while flying its nice to be able to compensate for the laptop's audio amp having to drive two sets of headphones via a splitter.

Here ya go <$30 fix, and its purple to boot.

i am not a computer pro i am just a student how the hell i was suppose to know , no message or warning even came up , be fare man

are you a fan of common sense dude? treat your possession with respect if you want them to function properly! lol
