Word Origin & Etymology

Coined in the 17th century from the Greek 'mikros' (small) and 'phōnē' (sound, voice). Originally referring to an ear trumpet for the hard of hearing, its modern sense as a device that converts sound waves into electrical energy dates to the development of the telephone in the late 19th century.
