Mouth & Speaker

Analogy Paragraph

Over time, men have succeeded in being able to create a modern speaker as a replication of the human mouth. Both the mouth and the speaker are used to communicate between different people as well as with animals. Also, the funnel shape has become a common denominator since this is the shape best suited to resonating sound waves. Third, sound waves are created by vibrations; the human mouth utilizes the larynx and speakers use what is known as a cone or diaphragm. Fourth, these vibrations can only be made when there is tension since sound is made from high frequency vibrations which require tautness. Lastly, both the mouth and the speaker require a sound medium – most often air – to vibrate, which can then in turn transfer those vibrations to our tympanic membranes in order to create what we percieve as sound. Although still remarkably simple, the modern speaker has made great progress in its imitation of the human mouth.
