One bluetooth receiver and multiple transmitters?

I need a bluetooth receiver to receive a signal from few transmitters. There's extremely little information about bluetooth hardware on the internet. Google gives a lot of topics about android and iphones, but that is not what I'm looking for.

What if we will take something similar to this one: http://www.mdfly.com/index.php?main_page=product_info&cPath=8_52&products_id=1047 Is it even possible in theory?

The real problem is that receiver should be smaller than transmitters. So it is impossible to put few receivers in one box.

If you will prompt me which way to dig, I will be truly grateful for you.

Here is a small pic of what i really looking for.

You need the dual stream Bluetooth adapter to connect multiple headsets or speakers simultaneously.
