Flight attendant then reported smoke in the cabin. I (PF) notified ATC; declared an emergency and received a vector back to land at departure airport. Uneventful landing about 10 mins later. ATC did a fantastic job. Fire crews met aircraft as we taxied clear of runway. They noted nothing abnormal and escorted us to a gate where we disembarked passenger and maintenance began inspecting aircraft.
