Here is a circuit of earpiece and Led connector of Atom and 68xx series.
As I have 2 atoms an 1 atom exec and tried 6815, I know all these series has poor quality speakers, microphones and buzzers and low Voltage output.
I tried to change buzzer with different mades buzzers but again very low dessibels and hard to hear output gained so I decided that it is about the voltage/power which mainboard gives is just not enough.
I draw an easy open circuit of buzzer and around.
Question is simple:
If one or two reostas R1 and R2 are shortcutted (with some solder), will volume get higher?

After thb introduced their first 'real' blueangel carkit, could this be the second ? I prefer this one because you don't have to connect a wire, but have a real cradle. The gps is also a plus.

I have it installed now and it worx good. Only problem is that it keeps muted VERY long (about 10 - 12 secs) when the BA produces a sound. Have to find somthing to fix this. I know this is a problem of the carkit because when the mute wire is grounded it switches directly on & off.
Just purchased this, and it looks pretty good, but the instructions are a bit naff.
Do i gather that the car kit's control box in effect gets placed in circuit "between" the car's head unit and the Front Right (or left) speaker. The cables are labelled radio FR + and - and FR speaker + and -. Do I just cut the iso cables for the front right speaker and connect the two ends to the ends of the car kit cables? I'm fine with car audio so this shouldn't be a problem
Does the car kit mute the radio for *every* noise or just phone, tom-tom etc? I guess I could just stick a switch in the middle of the mute circuit if i wanted to stop this (like WMA playing through aux in on head unit)
Hoping to have a play tonight...
It depends on the car you have. I have an Opel Omega with Bose Sound System fully integrated. At the passenger side under the glove compartemant was a plug that had al connections. The BSS has a phone audio input that outputs the pda sound to all speakers including Tomtom, and yes, all system sounds come over the speakers too. If this bothers you you could turn the sounds off in the Sound & Notifications menu. Check your car, maybe it has such a same plug (for factory fitted Carkits). First i wired it directly to the radio but it produced a horrible sound when the phone was cradled. It sounded like if 10 cats where fighting on the backseat. But that is over now. Could you let me know how long it takes for the mute signal to UNmute it after a sound is played. It takes about 12 secs here and that is WAY to long for every damn sound.

Oh ok. I have a vauxhall vectra with the same mobile pre-wiring so I wonder if that might work for me as well.
Did the car kit cables just clicp straight in or did you 'butcher' them?
I'll let you know about the delay to turn mute back off again once i've fitted it (probably at the weekend )
What i did not to kill the originall plug is that i soldered off a connector from a broken VGA card. It should be the same one as that where you plug in your IDE HDD at the back off the HDD (male plug strip). I soldered all the carkit wires to that. It almost looks factory fitted. Pay special attention when connecting the audio wires to your plug. At first i fixed tham at the back of my radio but that made a sound of 10 fighting horny cats on the backseat. Be sure to connect it to the plug because there is some filter between it. At least that`s with my carstereo (Philips CCR800 /w Bose Sound System.
If anyone could help me with modifying teh Tomtom 5 sounds the help will be appreciated. I unpacked all the voice files but i can`t seem to find the RIGHT editor to open these .ogg files. I tried SoundForge and Audicity but no luck. They can`t open them.
Hi,
yesterady I recieved my XDA IIs and a THB handsfree cradle for it.
As I noticed that the THB device is only Mono ( the TEl-In at my car stereo is mono too :-() I decided to do a littele modification today. I added a wire for the CAR_AUDIO_R to the connector and added a stereo-out to the THB cradle that now goes into the AUX of my car stereo.
I also added a switch to switch from "normal handsfree" mode to "just AUX" mode. The switch disconnects the IN_CALL, Analog GND and the CAR_AUDIO_L from the THB handsfreeset and connects it to the stereo-out (that is already connected to the CAR_AUDIO_R) I added.
I installed the special wavedev.dll that THB offers so every sound is redirected to the 22 pin connector if the XDA is in the THB cradle.
So far it works as I expected:
If I switch the switch, the radio is not muted anymore when the XDA produces a sound and I can here MP3s in stereo via my aux-in on the car stereo.
The downside:
The audio quality !!! - the signal that comes from the 22 pin connector seems to be pretty poor. I already installed the BASSBOOST plugin (which did improve the bass) but compared to my brothers pretty cheap PNA the sound still is pretty poor.
So my questions:
Any hints to improve the sound?
Are there any software issues (I am not sure what ROM i use ATM because I first wanted to get the HW part running _ is is some unmodified O2 UK ROM).
Are there any hardware improvments I can make here ( I saw that the homebrew Car kit in the wiki part does not just connect the audio pins but adds some electronics there- can that help or delivers the CAR_AUDIO_L/R bad quality in general ?!
Thank you for your help.
Let me know if what additional information can be usefull here and sorry for my english.
Best regards
P.S.: I am looking for the quality because my initial plan was to add also an ASUS WL-HDD with all my music on to get rid of burning CDs and be able to copy the music I want to hear from my desk direct into my car via WLAN.
Hi
The bad audio quality problem was talked about many times in past.
Still, there's no solution. Simply, the bottom connector audio out is designed for GSM Voice only. THB modified wavedev.dll to route all audio to bottom connector.
That's useful for eg. sat-nav, but not for high quality music.
Another problem that ocurred in my BlueAngel during DIY car-kit research, was the IN_CALL signal.
My BA doesn't provide +5V on IN_CALL ever ! Regardless of phone state, CAR_ON state etc...
Unfortunately, I don't have an original THB carkit to test my BA on.
I'm not sure if my BA's IN_CALL signal is dead or something else's wrong :/
Can You at least tell me what ROM version do you use in your BA ?
Alright, my friend has a blackberry and when he's listening to music and his phone rings he can hear it ringing through the headphones. Not only that, he can answer the phone and hear the person in the headphones while talking to him. He basically holds the phone in front of his mouth and talks with his headphones in. Also he doesn't have a mic on his headphones.
I've always wondered if this was possible with the x10. When my phone rings and im listening to music my music stops but the phone rings out loud and not through the headphones. I tried to answer it and see if I could hear them through the headphones but I can't and the person who called can't hear me either unless I unplug them.
Is there any way to fix this so I can hear the person through the headphones and talk to them by talking into the phone?
Sorry if the post doesn't make any sense, I'm tired as hell, just got back from work.
Your head phones come with a mic, imo I think that's better than holding the phone to your mouth.
Sent from my X10a using XDA App
I understand that the default headphones come with a mic, but they never stayed in my ears, which is why I use my own in-ear headphones. I want to be able to use them to listen to the call tho.
But the default headphone cable that comes with the phone has a headphone jack to plug in any headset you want to it, and still have a mic?
I've fixed all my headset issues by buying a £10(roughly) wireless headset adapter off eBay. roughly 12-14 hrs battery life out it (so lasts about a week with moderate usage as I mostly use it in the car on 1-2 hr journeys and do them once or twice a week). Good buy!
Hi Hypercore,
We seem to have gotten our phones from the same place. The default headphones came with a removable mic. When I got mine, I had headphones (with a 2 contact TRS 3.5mm connector + a shorter wire with a microphone that sports a 3 contact TRRS connector).
Heres's the way the tips rings and sleeves work (I think... correct me if I'm wrong)
The headphones TRS
Tip: Left
Ring: Right
Sleeve: Ground
The "Mic TRRS jack"
Tip: Left
Ring1: Right
Ring2: Mic
Sleeve: Ground
So you need a TRRS connector that includes a mic + TRS Headphones or a set of TRRS headphones that include a mic built-in.
There are some pics on wikipedia, just search for TRS connector.
Hope this helps.
I know what you mean, the mic comes with the phone but when I hook my headphones up to it the wire is WAY too long.
Boohoo, just bundle it up a few times and put a rubber band around it keep that end in your pocket.
I just snipped the headphone's wires, slipped some shrink tubing, heat wires up with a lighter (to remove the "varnish/wax/stuff" they put on the copper wires these days), solder, slip the shrink on top, heat up one last time and voilà! Headphones with a short wire.
Hurray!
I have to admit that the mic wire + normal headphones make for a really long wire.
I was replacing the body and battery and damaged the earpiece - the piece itself fell apart and the internal wiring was separated from the two 'poles' which connect it to the the lower jumpers.
Booted up and the top speaker doesn't work. I was wondering if I can modify system audio i/o to redirect call audio through the lower speaker?
If not could I remove the earpiece and reconnect the internal red wiring to the poles and reassemble it?
hello guys so i'm facing a little issue just bought new over ear headphones for use with my xiaomi mi 8 but the volume does not seem to get loud enough so my phone can drive these headphone properly due to not enough power being supplied to HS , so i was wondering if there is some kind of mod to increase output though type c port and i don't mean EQ like v4a and else
Use a pair of high-quality earbuds and /or a high-quality headphone to improve your Android device’s sound quality and volume.
