Your mobile phone communicates with the phone network using electromagnetic radio waves.

One feature of electromagnetic waves is that when they pass through a wire, they create an electric current in the wire.

This is what's happening. The phone is generating electromagnetic waves so it can communicate with the phone network. These waves are creating electric currents in the wires that go to your speakers - only small currents, but they are there. Your speakers amplify these currents and convert them into sounds.
