speaking tube
A teacher speaks into a speaking tube to give instructions to the classroom next door.
Noun: A speaking tube is a simple acoustic device consisting of a hollow tube. Its primary function is to transmit the sound of a human voice from one location to another, typically between different rooms or areas within a building, allowing for basic voice communication before the widespread adoption of electronic intercoms and telephones.
The term "speaking tube" refers specifically to the physical tube apparatus itself. It is used to describe both the device and the act of communication via this device. * In historical contexts, speaking tubes were common in large houses, offices, and ships. * The phrase is typically used with verbs like use, speak into, talk through, listen to, or install.

- "Put that in your pipe and smoke it!": While this idiom originates from different contexts (smoking pipes), its structure humorously echoes the action of speaking into a tube's mouthpiece. It is used to tell someone to accept a stated fact, however unpleasant. It is not directly about a speaking tube but shares the word "pipe," which is sometimes used interchangeably with "tube" in this context.
