How to connect speakers to multiple audio sources?

Question

Bluetooth

Hello.
Initial data
There are speakers, a TV, a couple of MacBooks and several phones with bluetooth.
The task
To be able to output sound to speakers from different devices. TV can be wired. But from other devices, it is desirable to use a wireless method: Bluetooth or Airplay.
What you want
So that at any time you can start broadcasting sound from any device: just watched the series on TV (the sound was in the speakers), then turned on the music from the phone on the speakers, and a minute later from the macbook.
I do not want to suffer with connecting devices every time you want to output sound.

Answer 1

The simplest option suggests itself - connecting through a mixer. The signal sources to the remote control can be any. The market is full of them. It all depends on the budget.
