Bluetooth speaker that can pair with other speakers

I have a design for a bluetooth speaker. I want quality audio parts to make a bluetooth speaker that can link with other to the same bluetooth speakers for extra sound. I want the battery to be able to be charged and not to use double aa batteries, etc. I want a lithium ion battery.

So, basically a portable slim bluetooth speaker that links together with my other speakers to create more surround sound around. I have the design, but I am clueless how to actually build the speaker.
