This is a radio system that I have designed to be used in different rooms. One of these radio speakers would be placed in each room, when someone walks into a room, the speaker turns up the volume automatically, and turns down when the person leaves the room. This is done by an app being installed onto the smartphones which would sense the location of the user, and also operate the whole system. Different radio channels can be put on in different rooms as the users would be able to set up their favourite channels on their smartphone app.
