Have you taken a closer look at the speaker assembly? Making sure the pins are not bent and that it's secured to the induction flex proximity sensor?

The location that the speaker connects to is part of the induction flex ribbon cable.

It's often overlooked that you have to remove this part in order to fix this ribbon. It wasn't very securely attached to the ribbon so I think this should be worth a look. The only downside is you have to remove the logic board to look into this.

I had some buzzing and low volume from my iPhone and reseating the speaker to the cable fixed it.

My wife had the same problem with her iPhone 4. The earpiece speaker suddenly went very quiet almost muted so you could hardly hear the caller.

I tried some of the other suggestions such as sucking and blowing on the earpiece but no joy. I was about to order a new earpiece speaker and some tools when I though to try one last go at cleaning the area with a very tiny pin.

I scraped the surface of the speaker and got a few bits of dirt etc out, and then tried sticking the tip of the pin into the speaker mesh and pushing it up, down left and right slightly to see if it had come loose from the connectors. This appears to have worked as the earpiece speaker is now back to normal and working fine.

Thanks for the tips. Great site...!

I spilled my Iphone with sweet juice. I tried toothbrush cleaning and air compression. It didnt work.

Then i wet toothbrush with a little saliva and tried again. It worked.

Dried juice was dissolved and earspeaker volume increased perfectly

hope this will help

When a speaker is working but has very low volume it is usually a hardware issue. Speakers work using two wires, One is signal and the other is ground. If one of the cables is lose the speaker will still work but will be very soft. Try unplugging and re-plugging the speaker in and look for broken ribbons.

if the i phone 4g key pad sound is heard and ear speaker is not working it goes to loud speaker it is the complaint of the induction proximity cable that is the on/off switch cable replace it , it will work

This worked for me aswell!! I remember now dripping some icecream on the speaker mesh, I wiped it off and forgot about it, but then this speaker problem started happening. I cleaned it with a wet toothbrush as someone suggested and sucked on it, definitely improved the volume problem. I can now hear when speaking with someone through the ear speaker!!!

I spilled paint on my iphone 4S and the speaker problem happened to me too! but i just tried scrapping it out with the end of a pair of scissors and a key and it made it slightly better. and after sucking on it for a while, it is now completely fine! thank god for this thread it saved me time and money !!

The blow job method worked for me as well. I guess sometimes our iphones just get tired of listening to our schitt.

I had the same problem!! What you gotta do is (if you have one) use a nipple pump, and place it on the speaker, and start pumping hard and fast!! Once you create enough suction, it will suck the protien right out of your speaker! and then it will be good as new! Good Luck and happy pumping!! :)

omg this really works! lol too funny

thank you so much. it realyy works with sucking.this method save me a trip to apple store. Espcecially, i have to go back to Dallas for app store replacement or repair, since I am now in Mexico city. It is so amazing. My wife and I decide to suck my iphone 10 minutes every day in next week. thank you again, lan

blow with compressed air into speaker and works o.k.

I was try to change speaker but did not help.

Awesome fellas. I tryed sucking on the ear speaker quite a few times, and it did make it a bit louder. So I decided to get the vacume cleaner ready to suck. I then sprayed contact cleaner into the speaker, sprayed some more, (soaked it!) after a bout 10s I jammed the vacume cleaner nozzel onto it sealing it off. Pushing it on and off really fast and aggressively (thinking fix it or stuff it) and Vola, my speaker is loud as brand new.!!! I'm wrapped !!! It is really loud !

Another one confirminging that the sucking worked!! I seriously thought this was a brilliant gag, but it worked.. Thanks a million.

embarrassingly sucking actually worked. amazing.

Ok I tried this and it only works temporarily but then gets low again in like 2 seconds. So everytime I suck air through the speaker opening the sound goes normal like a said for about 2 seconds then it's back to low volume again. Why isn't it working? I even disassembled my 4s and took the lcd off and replaced the speaker cover, blew it out with an air compressor and no dice. Any suggestions?

Working my ear speaker amazingly after sucking and brushed with wet tooth brush...thanks guys..

It worked. My wife was unsuccessful manually. So I brushed it with a wet toothbrush and then hooked it to the shop vac and sounds great now.

I tried sucking the ear piece and my volume returned about 50%! Next I used my vacuum attachment hose and the strong suctioned returned my volume to 100% working order! Thank you!!! I've been without my phone for over a month now!!! Thank you so much!!!

I've had 2 4s iphones do this and never could make them work again.

You wouldn't by chance work in a weld shop or other area with tiny metal airborne particles?

I'm beginning to think that's why mine died. I noticed these little dark "dust" particles settling on the ear speaker grill when I came home from work. When holding a magnet over the grill, I noticed that the particles jumped out and stuck to the magnet.

Hate to think how much of it I'm breathing daily.

anyway, I believe the ear speaker magnet must be fairly strong and is sucking these metal particles into the grill where they cannot get out once stuck to the speaker.

I think they are either muffling the speaker by covering it, or posiibly shorting out the speaker.

This is all a theory I have. This time, I covered the speaker grill opening with a strip of velcro loop material to hopefully keep the metal dust out of this one. We will see if it also dies.

The magnetic attraction would explain why blowing it out with compressed air did not clear the debris in my case.

Wow Justin!… This is the 2nd iPhone I have the speaker issue with, And Yes, I am a Welder/Metal Fabricator. I used to have a trick where as I would put a magnet in a rubber glove and rub it over any opening to pull the metal dust out of the speaker ports (thats the trick I use to get bits of metal out of my eyes). That worked GREAT with my 3gs BUT it seems that the magnet is what is causing it to fail in my iPhone 4s. Seems to start as soon as I try it. I had tried to keep the 4s in a life proof case but that was for from dust proof so now I keep it in a SeaLine dry bag made for iPhones. unfortunately, the sucking and blowing hasn't worked for me yet.

Here's my 2 cents. I'm an engineer at a memory manufacturing company and these stupid Iphones are intimidating. Anyway, I tried to suck on it and it wouldn't fix it. Today I swabbed 91% rubbing alcohol on the ear piece and while it was still wet, poked a needle into the holes of the screen. After that I sucked on it and then ran a blow dryer on it for a few minutes. This worked. Awesome post. Thanks

it work with me with some hard sucking

Thank You

a kinder egg exploded in my pocket the other night. i did this sucky thing earlier. it felt weird like i was giving my phone a blow job or something. it didnt work so i basically deep throated the thing. it was like the ultimate phone blowie. now it wont even turn on. i presume all my saliva has gotten into the phone now. any one any suggestions please?

aaron

even it's worked for me.... Thanku so much

It worked!! I sucked that ear speaker 3 times and it started working fine again thanks for the tip.

Mine earphone loudspeaker became very weak. So I cleaned the metal screen with a dump tooth brush and then dried it with 15 seconds of cold air from a blower. I added some sucking, and the voice became loud and clear. So simple

Another one confirminging that the sucking worked!! I seriously thought this was a brilliant gag, but it worked.. Thanks a million.It really worked.I'm a sucking believer now.Thanks for the tip.Who would have thought this little gag would work!Again Thanks.

yoby

oh yes it work please dont suck just bang bang your iphone from top side 2 to 3 times it start working .....

Believe or not, the first answer worked. When I pulled off the plastic protective sheet from my new digitizer, a small piece of plastic stayed and was covering the ear hole. When I sucked in a few times on this ear hole, a small piece of plastic came out in my mouth. Evidently when I peeled off teh protective plastic sheet, a small piece stayed behind and was covering the ear hole. I couldn't see it due to it being transparent. Afterwards, Volume went up 2X.

Thanks OP!!!

Worked. what can you say. Used the suck method and then an electric toothbrush "between teeth" attachment and then sucked again. Tried a test call and had to move it away from my ear because the voicemail prompt voice was so loud.

When I took the Otterbox case off, it looked like a sunscreen buildup on the actual phone surface around the earphone. Guess that explains that.

Thanks, everyone for your input! I tried everything mentioned here- the compressor air, banging the phone face down, poking holes, sucking. But then... I couldn't find rubbing alcohol, so I used acetone(nail polish remover) with a toothbrush and my frustration is over!

Nice topic!! I was just about to replace my ear speaker and I read this. Mine was not working at all, so not even a smallest sound from it... I sukit it a few times.. and it didn't work... So I said mine has to be interruptend somewhere and is a serious problem... But then I read again iwillfix's reply, and tryed to suck again really really hard.... Somehow suddenly it came back to life at full volume !!!! So if some of you tryed and didn't work from first time, try again more harder.... Thanks

The sucking just worked for me too. Thanks for posting guys.
