At FL390; the 'B' Flight Attendant called the cockpit and spoke with the First Officer reporting an acrid electrical smell at mid-cabin. The 'A' Flight Attendant also smelled it; while the 'C' Flight Attendant did not. At that time; the Captain spoke with the flight attendants via the inter-phone to get more information; and he determined that a diversion was necessary and we agreed on an alternate airport. We coordinated with ATC informing them of our intentions and the emergency was declared. We complied with the Smoke/Fire/Fumes QRH Checklist. The Captain was the pilot flying and I communicated with ATC during the descent; spoke with the flight attendants per the abnormal checklist; and retrieved the airport charts from the alternate binder. I completed all of the abnormal and normal checklists as we were on final approach; and we landed overweight at 129.4 LBS and stopped on the runway. The Tower asked if we could clear the runway; and we did so. At this time; the fire crews pulled up next to the aircraft and asked what our area of concern was: we reported over-wing/ mid-cabin. Fire crews completed a visual exterior and thermal imaging inspection with no defects noted; and we then taxied to the gate. After coordinating with Maintenance; Dispatch; and local Customer Service; the customers were deplaned.
[The Flight Attendant] described that the fumes could be from a possible electrical fire in the cabin overhead. He indicated that the fumes were not dissipating.
