HP IPAQ 6828 speaker problem - solved

Hi,
As many of you know that the HP 6828 has a problem with its headphone socket. It happens that after you remove the headphone from the headphone socket there is no sound from the speakers. The phone works O.K with the headphone and the phone THINKS that the headphone is still connected even you remove it from the socket.
The problem is with the headphone socket. So, if you are lucky enough and still have warranty - you run to HP and get it fixed. But for others like me whose phone is out of warranty running to HP is not feasible because HP does not service at the component level - they will just replace the whole motherboard at an astronomical price.
So, if you can get the headphone socket you can get it replaced locally. You can get it from here:

But if you are a bit enthusiastic and have some DIY skill you can fix it yourself as I have done it:

There are six contacts on the headphone socket. three on left and tree on right.
If you short the upper two contacts of the right side your phone speaker will start to work again - but you can not use the headphones even if you insert it - it will not work. So if you don't use the headphones this is the solution for you. Just solder a small piece of wire between the two contact points - and voila.
But is you want to use the headphones too - there is a workaround too. You attach a small piece of wire to right top most contact and another one to middle contact on the left side as I've done in the picture. Now if you touch these two wires momentarily once your speaker will start to work - and again if you touch these wire and insert the headphone - the headphone will start to work. This will act as a toggle switch. You bring out the wire from the backside of the battery and keep it between the battery and the battery cover. You set your phone to use the speaker normally - and when you need to use headphone just open the back cover and use the "Switch". After you finish hearing music or radio - open the back cover and use the "switch" again.
So this is a no cost solution to the speaker problem. Although, it is better to get the headphone socket replaced. I ordered mine and it will take about 20 days to arrive. So till that time - long live DIY

Head-in-a-bucket microphone

Can anything be done about the poor mic. sending HIAB signals to others? To me it is in a crazy place on the side exactly where you old the phone, so your fingers cover the mic. hole. there also seems to be a plastic shroud over the mic. once the back is off. Does this shroud do anything?
Thanks
I think this is for you McKeebop

Sounds like you need the cone of silence!

I've also read that some users puzzled about that opening at the side before.
Atm, I'm not really sure what to do.
I'll take a closer look this evening.
I guess a Dremel can help us out of this situation
I'll be back later, as reallife takes too much time atm...

Thanks for that McK.
There is a plastic insert over the Mic. hole in the chassis, if that makes sense, reducing the actual orifice to a very small aperture.... so a dremel should not be required. I just wonder why they have sleeved it down with an extra piece of plastic and not included the moulding in the main case. You might know, having disassembled your phone!

Just did some investigation...
It seems to be really the mic underneath that little cover.
I don't know what the phone did wrong to be treated that bad by S///E.
I thought first that heavy fastened vibra engine is worst of all.
But a soldered mic?
WTF?
There isn't even a chance to switch the mic with a solder iron.
You had to give it a try with a hot air station.... or throw the phone to the basket (what I guess is intended by S///E).
But another thing:
I tested the mic from the test suit within the service menu.
Whatever I did, which hole I covered....
The recording volume remained similar at all time?
So maybe that whole "uuuh, I placed my finger to the hole of the mic and nobody hears me " might be false + placebo?
Could anybody else please give it a try?
My Ears aren't that good anymore

So its just a crap mic. or poor accoustic software then?.........................

You can easily point it out:
Use a Headset.
- If Mic quality is still bad; its the software.
- If Mic quality get better; the onboard mic sucks..
I'd say its that subminiature onboard mic
I can't say it after all.
I use to telephone 95% of time from my car with a Parrot MKI9100

Replacement of broken headphones with SENHEISER earbud

After 6 months of using headphones on my Samsung Galaxy Note, I noticed that the Samsung earbud snapped it self as you see in picture. for unknown reason, certainly not from me because I keep them safely in SENHEISER purse.
View attachment 1400252
So I decided to replace my handset with SENHEISER earbud (anyway, the sound was very bad).
During disassembly noticed that the handset is permanently glued, so that there is no other way but to break it open.If you try to open it, you would encounter this fact.

Right Earbud,
white wire is ground and red is right channel
Left Earbud, (sorry no picture) green ground wire is a blue left channel.
And after 20 minutes of work and soldering, here's how it looks.
For the sound I will not even talk (SENHEISER QUALITY:good, everything works fantastic.

nice job :good:

It would be nice if you added a female mini-jack so you could use the original Samsung cable and microphone and use any headphones you could like.

I made my custom fit earbuds using a Sugru substitute you can easily make at home.
http://www.instructables.com/id/How...stitute/step14/Comparison-of-Oogoo-and-Sugru/
To prepare the earbud, I remove the rubber cone and cut away the "bell" leaving only the "cylinder" portion which I replace on the shaft it came from.
I placed a single layer of Saran Wrap™ over my ear, then indented a portion into my ear canal - to provide a barrier to prevent any possible skin irritation from the acetic acid produced during curing.
I mixed the silicone caulk ( not GE II ) and cornstarch about 50/50, applied a portion to an earbud while it was still quite sticky (being careful not to plug up the hole in the cut off rubber cylinder), waited for it to set up a little so that it wasn't gooey (more formable), then shaped it a bit to a cone, then inserted it into the indent in the Saran Wrap™ in my ear and waited about 10 minutes for it to cure.
I love the sound so much I rarely take them out of my ears.
Here's a picture...

Good job ,but as someone said you should of used mini female . I love this -see pic as I can use my full size cans without degrading them with switches in the path when I want to use on other things . Plus I've a lot of cans so I'm not tied to my S 485s

Very nice!

nice one bro... :good:
but does it feel comfortable to wear that?

[Q] Second microphone problem?

Hello,
AFAIK Galaxy S5 has two microphones, one for calling/video and general audio. The second seems to take care of the call when in speaker.
A friend of mine has a S5 and the calling with earphone is working just fine, but then he switches to speaker, the opposite can't hear anything.
Anyone with this same problem/knows more about this spesific issue, how to repair etc. I'm worried that the second microphone is soldered to the motherboard and can't be (easily) replaced.

The secondary microphone is used for active (ambient) noise cancelation. This can be weighted as well when recording audio. Normal mode uses both mikes omnidirectionally. Interview mode uses the secondary mike only in a directional beam pattern. And conversational mode takes directional top and bottom audio.
There are also equalizer, shaping and DSP effects. Your issue could be caused by a number of things from speaking too softly, poorly chosen presets or an obstructed or damaged headphone connector or microphone. Try using the Samsung "wise voice" feature that adds microphone gain to compensate for users who speak softly or hold the phone too far from their mouth.
Before replacing a microphone, try holding the phone closer to your mouth and speaking louder. Also try a full backup followed by a factory reset and see if that solves the issue. The primary microphone is soldered onto the charging port assembly. Less than $10 + shipping if you look around. I haven't looked into the secondary mike, but no doubt a Google search will tell you all about it.
.

Thanks for the very explaining reply, didn't know about those modes that specific.
Yes, I forgot to add to my op that the S5 I'm speaking is broken, the screen is cracked from up-corner of the screen so I suppose that the actual second microphone could be broken too. I looked some motherboard-analysis and seems that it's indeed soldered to the motherboard. None of the analysis I looked didn't actually mention that there is a second microphone on the motherboard, but there's a small piece looking just like a microphone on the up-corner of the motherboard.
I attached a Chipworks' image about S5's motherboard and added a red arrow indicating the part that I think is the second microphone. Full article on Chipworks: http://www.chipworks.com/en/technic.../resources/blog/inside-the-samsung-galaxy-s5/

Help On Fixing Headphones

So I'm using the Samsung earphones(The ones with the flat cable. Model HS330) that came with my Galaxy S4. These were a good set of earphone but then, the plug is messed up.
Audio tends to only come from one side or no sound at all but I can get it to work when I mess around with the cable near the plug.
Eventually the cable decides to give up and messing around with the cable doesn't work anymore.
I need help from you all to get this fix sorted out.

These are the earphones I'm working on.
So I'm trying to get the earphones fixed by replacing the plug with a spare headphone plug I have laying around. These Samsung earphones are really good compared to the cheap ones and quite expensive if you want to buy a new set.
These are the headphone cable I have. It is a TRS plug(2 rings on the connector. Common on most PC earphones) unlike the Samsung's which is TRRS(3 rings.This type is common on earphones with a microphone.Basiclly any earphones that comes with a phone). Using this means the microphone and volume control on the earphone won't be wired up.
I stripped the cable on this one and there are 3 wires to deal with. The red and green I marked out are the Left and Right audio. The copper wire is ground.
As I said, I can't wire up the mic and volume controls with this cable but I don't really care about this part because I'm using these earphones on my PC most of the time. I just need L,R and Ground
I chopped off the cable on the Samsung earphones and stripped it to reveal the wires. This is what it get. All three wires are actually wrapped with these copper things but at this point I'm confused with is L,R audio and Ground. I need to find these 3 wires to wire up to the cable I have.
If I sorted out the wiring, I can solder them all in place and done. But I need help.
Anyone who can help me sort out the wiring of these Samsung earphones with be appreciated.
Regards.
