speaking tube
Ship's communication pipe
A speaking tube is a pipe or tube used to transmit voice between rooms or decks, common in ships and large buildings before electronic intercoms.
One speaks into one end and is heard at the other: The captain called down through the speaking tube to the engine room.
Now largely obsolete, replaced by telephones and intercom systems.
