A speaking tube or voicepipe is a device based on two cones connected by an air pipe through which speech can be transmitted over an extended distance. While its most common use was in intra-ship communications, the principle was also used in fine homes and offices of the 19th century, as well as fine automobiles, military aircraft, and even locomotives. For most purposes, the device was outmoded by the telephone and its widespread adoption. This device was also known as a "megaphone", but that use has since become superseded.

Famous quotes containing the words speaking and/or tube:
“I have a talent for silence and brevity. I can keep silent when it seems best to do so, and when I speak I can, and do usually, quit when I am done. This talent, or these two talents, I have cultivated. Silence and concise, brief speaking have got me some laurels, and, I suspect, lost me some. No odds. Do what is natural to you, and you are sure to get all the recognition you are entitled to.”
—Rutherford Birchard Hayes (1822–1893)
“Even crushed against his brother in the Tube the average Englishman pretends desperately that he is alone.”
—Germaine Greer (b. 1939)
