This reverb unit, it vibrates?

Can anyone identify what appears to be a strange vintage 'wire reverb' unit
, which seems to combine a speaker enclosure with a piano-like string attachment to provide the resonance?

The description, in full:
The speaker is a " ALTEC LANSING " MODEL 600 B. This is an expensive speaker probably a 1950's or earlier. This cabnet speaker as you will see by the photos it contains an unusual piece of equipment. The top comes off an you see a 45 lb piece of metal that looks like a funnel with piano wire that runs on all 4 sides starting at a 3 inch length piece of wire and progresses up to 17 inches long . This piece of equipment fits in from the top and hangs upside down , around this unit is pieces of red velvet and under the velvet material is pieces of sound boards on all 4 sides with the standard S CUT OUTS. Now on the base of this unit is the driver speaker and that is the " ALTEC LANSING ". How this unit works is beyound me , I guess this is either a reverb unit or an echo chamber type unit.
The string resonance (?) unit is shown clearly in the pictures.
