History of Microphones
In 1800s In older times when there are various addressing phenomenon of large set of audiences. Nowadays microphones are connected with entertainment and music fields but in earlier period around 1600, scientists started to research and develops about how to magnify the sound. It was charles wheatstone who played important role in developing microphone on 1827. He is know as the best inventor of telegraph and he was the only first person who had the interest in acoustics and he recognized sound can be transmitted by waves with the help of mediums. In 1878, alexander graham bell invented liquid microphone and launched telephone voice transmitter.
In 20th century In 1915, vacuum tube amplifier is used to improve the volume of many devices including microphone. In 1916 and 1923 moving coil microphone were built and it is considered to be a first microphone broadcasted ever and later magnetophone developed by H. J. Round became the best standard microphone in BBC studios. It was improved by alan blumlein who released the HB1A and likewise ribbon microphone were developed. Microphones were developed over the year by various companies.
What is a Microphone?
The microphone was developed by Emile Berliner in the year 1877. Microphone acts as an input device that is used to convert sound waves into electrical waves. it captures audio by conversion of sound waves into electrical signals which may be analog or digital. This process is implemented by using the latest high definitions and processing computers. Actually, the first microphone is based on the liquid mechanism, here the diaphragm was connected to a current needle which cannot produce clear speech. Besides the type of device microphone is designed for directionality let me give a clear example Omnidirectional microphone picks all sounds in any area but the disadvantage of using this is unable to focus with background noise. Microphones are used to capture sound in various applications such as music, podcasts, videos audio speeches, etc. The microphone is the best invention it makes and saves more energy by delivering speech with a good amount of efficiency.
