I had purchased a Headset [ Which will be referred as Hands-Free fom this point ] from a local dealer. It is not an original Nokia Enhancement.. and SO it started generating some stray sounds and made the speech deteriorated. So I thought of hacking in to the Hands-Free to know what the problem was. And I found the problem..! It was a loose contact between the microphone and the ciruit board. I got some picture of that hack for my valued readers...
The Components are ....... [ in serial number order... ]
1. This is the 9 pin connector which is plugged in to the phone.
2. This is the earphone.
3. This was the microphone [ condenser microphone ] that caused the problem.
4. The circuit board to whcih the microphone was connected to. See the holes from which the microphone tore off. The mic was attached from the other side of the board.The board also has an on-off swich at the centre. It is with this switch that calls are recived or ended.
5. The clip to attach the device to the tie-clip.
6. The coverings of the circuit board.
Please note that this is not the origional Nokia enhancement. This one is locally manufactured and is of less quality. The original enhancement may vary from this and is of very good quality.
