The History of the Development of the Microphone

- Apr 15, 2019-

A microphone is a device for converting sound power into electrical power having substantially similar wave characteristics. These devices convert the sound waves into voltages that are eventually converted back into sound waves that are amplified by the speaker. Today, these portable devices are often associated with music and entertainment, but the history of microphones dates back to the 17th century, and scientists began looking for ways to amplify sound.

1665: Although the word "microphone" was not used until the 19th century, an inventor was a pioneer in spreading the world of sound across distance. British physicist Robert Hooke has been acclaimed for developing an acoustic cup chord-type phone.

1827: Sir Charles Wheatstone was the first to use the word "microphone". As a famous British physicist and inventor, Wheatstone is known for inventing telegraphs. His interests varied, and he put some of his work into acoustics in the 1920s. According to the interest project, Wheatstone was one of the first scientists to formally recognize that sound is actually transmitted through the medium. This knowledge prompted him to explore ways to transfer sound from one place to another, even far. Distance spread. He studied a device that amplifies weak sounds. This device is called a microphone.

1876: Emile Berliner invented the first microphone that many people thought when working with the famous inventor Thomas Edison. The device used is a telephone voice transmitter. Berliner is a German-born American inventor, best known for his invention of the phonograph and phonograph record that was patented in 1887. Berliner had seen Bell's presentation at the American Centennial Expo, motivating him to find ways to improve the new invention phone. Bell Telephone Company was impressed with the inventors' idea and purchased Berlin's microphone patent for $50,000. According to, Berliner originally patented the microphone, but eventually the patent was overturned and later credited to Edison.

1878: Just a few years after Berlin and Edison created their microphones, the British and American inventors and music professor David Edward Hughes developed the first carbon microphone. Hughes' microphones are an early model of the various carbon microphones still in use today.

1915: The development of vacuum tube amplifiers helps to increase the volume output of devices including microphones. 1916: Capacitive microphones are patented by inventor EC Wente at Bell Labs; this device is often referred to as a capacitor or an electrostatic microphone. His task at the time was to improve the sound quality of the phone, but his work also enhanced the microphone. 1928: In Germany, Georg Neumann and Co. was founded and became famous for its microphone. Georg Neumann designed the first commercial condenser microphone, nicknamed the "bottle" for its shape. 1931: Western Electric introduces its 618 electric transmitter - the first dynamic microphone.

1942: With the invention of the radio, a new broadcast microphone was created. The ribbon microphone was invented for radio broadcasting. 1959: The Unidyne III microphone is the first one-way device to collect sound from the top of the microphone rather than from the side. This sets a new level for future microphones. 1964: Bell Labs researchers James West and Gerhard Sessler receive patent numbers. 3,118,022 for electroacoustic transducers, electret microphones. Electret microphones offer higher reliability and higher accuracy at lower cost and smaller sizes. It has revolutionized the microphone industry, producing nearly one billion a year.

In the 1970s: both dynamic and condenser microphones were further enhanced to reduce sound level sensitivity and make recordings clearer. In the past decade, many miniature microphones have also been developed. 1983: Sennheiser develops the first clip-on microphone, a directional microphone (MK#40) and a microphone (MKE 2) designed for the studio. These microphones are still very popular today. 1990s: Neumann introduces the KMS 105, a concentrator model designed for live performances, setting a new standard for quality. 2010: Eigenmike released, the microphone consists of several high-quality microphones that are arranged on the surface of a solid sphere, allowing sound to be captured from all directions. This gives you more control when editing and rendering sounds.
