If you read wikipedia, it has 79 channels, so every device will use
it's own. It is very possible that any of the channels gets
interference from other gadgets in the 2.4 GHz band, but knowing Linux
you very probable can move your gadgets to another of the 79 channels.
I know that in the beter wifi routers you can select the channel to
use, based on an interference diagram it gives you.
So if you experience interference, I'm almost certain it wil be
solvable. 
Also since audio is one of the early uses of Bleutooth, I assume it's
well developed to prevent and solve interference.
Maybe you can already solve your problem by moving the speaker to
another channel?
