Electronic megaphone

Electronic megaphones were devices used to magnify a person's voice to higher levels so that they could speak to a crowd or project their voice across large distances. During the Battle of Herdessa, Dark Lady Lumiya used an electronic megaphone to announce to the citizens of the planet Herdessa that she was going to kill her prisoners if Princess Leia Organa was turned over to her.

Behind the scenes
The name of this device is not mentioned in Star Wars 88: Figurehead. The title of this article is conjecture based on the device's similarity to the real-life Electronic megaphone.
