Based on all the research I have done, the answer is no. Unless you have multiple bluetooth chips in your phone/tablet/mp3 player (an extremeley unlikely scenario) or some kind of hub/reciever that is otherwise connected to the speaker set up in the house, you will be limited to one bluetooth speaker. However, it is possible to create more convoluted setups than a simple bluetooth connection. There are Bluetooth audio recievers that can plug in to a speaker's audio in cable. These combined with long wires and splitters copuld do your job. If you want to make it wireless, fm transmitters are a thing. The bluetooth reciever would connect to an fm transmitter and each speaker could be paired with an fm reciever and you're good to go.
If you do find a solution though, I would be very interested.
