Hello. I will need the experience of some hardware doctors in this!
I need to make something from a bluetooth headset, or from its parts: i must reduce a bt headset to the following piece :
1. bt chip+
2. baterry+
3. 2 pins for the speaker!

I will need to strip the microfone off, start button, volume buttons, leds , everithing!!
I need to end up with a device that will pair with bluetooth phone, and receive the audio signal from it, and send it to pins to wich I will attach a small speaker! The whole ideea is that I need to build a this device, wich will be very very small (max 1cm x 1cm x 1cm) without the battery, and will work in a wet enviorenment!! The problem with the water i will solve by putting everything in sylicon !!

So any suggestion???
1. what bt chip i use??
2. where i get some docs of it?? (pins, etc)
3. what does a bt chip need to work in there conditions?? (auxiliary parts or chips???)


If there is a hardware section please move my post!

I have attached a logical scheme for better understanding! In the yellow part is speaker wich is no problem. the core is the cip with ?other? component!
If I could find a chip that works only power from battery and line out to speaker, and it does not need anymore parts (black rectangles in scheme) it would be EXCELENT!!!!

I am confident that here i can get help, due to thhe size of the forums!!

What are you going to use it for? If you explane maybe it´s little easyer to help you.

well, i`m trying to make a one-way communications system. meaning that i need to place the device somewhere(very very small place) and if somebody is telling me something at the phone I will hear it!!

Check this sajt, here you can read about bluetooth and find manufactures of chipset.

thanks. will read and reply.

It is easier to buy a chip BT hands-free and open it, so you connect the speaker to you amplifier and the mic somewhere near you and you are sure that work.It is difficult to creat your own because you have to do with very high freq (2.4GHz).
