LARYNGAPHONE

Telephone Manufacturing Company of Dulwich, Londen [1] This name is derived from the word "Larynx" (strottenhoofd ) and was applied to a type of telephone handset where the microphone was actually pressed onto the throat and speech vibrations were transferred directly to the microphone rather than through the air.

The handset was intended for use in noisy situations where background noise would otherwise have been competing with the callers voice.

Some users in noisy environments used to put the microphone to their chests, but it was found that placing it next to the larynx was just as good, if not better, but easier to use.


Laryngaphone, 1929 Laryngaphone, a noise-excluding telephone which only transmits vibrations from the vocal chords when the microphone is placed against the throat or cheek. For the man who wants to annoy both his wife and his mistress
