The word "microphone" was not used during this time until the 19th century but an English physicist and inventor named Robert Hooke developed an acoustic cup and string style phone, where he was considered to be a pioneer in the field of transmitting sound across a distance.
A microphone is a device that converts acoustic power into electric power, sound waves to electrical voltages, then converted into sound waves that are amplified through speakers.
We associate microphones often with the music and the entertainment industry, but the device can be dated back as early as the 1600s when scientists figured out that they could amplify sound.
Incandescent light bulbs existed before Thomas Edison, and when other inventors got wind of Edison's tinkerings, they roundly sued him for patent infringement.
So what did Edison actually do?
He discovered that a special species of bamboo had a higher resistance to electricity than carbonized paper, which means it could more efficiently produce light. Edison got rich off the bamboo, and from superior manufacturing and marketing of his product.
Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements.
Scientist, physicist, engineer, inventor, none of these words describe sufficiency the life of Nikola Tesla. Maybe genius only can minimally describe the life of this man. He had fascinating mental abilities which allowed him to elaborate in his mind complex electrical machines and build them without taking any notes.
Nikola Tesla was a visionary that changed the history of humanity with his inventions. Tesla's vision was always ahead of his contemporaries; he imagined already two centuries ago, a world where people could communicate with radio waves, illuminate cities without using wires.
There is no single man who can be truly credited for the discovery of electricity, but some of the names which would pop up in the list include Benjamin Franklin and his kite experiment, and Nikola Tesla who is often dubbed as the father of electricity because of his understandings of this force behind most of the everyday items which we use today. From home entertainment to the lights outside the road, electricity is behind it.
