First microphone

I think everyone loves to listen to music whatever it is. As we all known, majority of the music are songs. So we never would’ve been able to listen to our favourite songs without microphones.

What was the first microphone is?

Let’s fly back in time to 1856. The French scientist Du Monsel was the first who noticed that carbonical diods significantly change its electrical resistance even with small changing the distance between conductors.

In 1877 american inventor Emile Berliner was invent a first operational microphone based on coal core. After one year in 1878 english-american inventor David Edward Hughes was made some improvements on Berliner’s invention construction by adding a membrane.


If we will carry a direct current between conductive plates, voltage at this location will depend on pressure on membrane.

This micro differs from the others in that it isn’t a converter but aplifying device because energy of useful elertric signal is produced by external source of direct voltage, whereas acoustic fluctuation only control an energy flow by changing a resistance.

Later I’ll be talking a lot more about different types of microphones and dedicate a specific article for it.

Thanks for reading my first serious article. See you soon 😉
