Ring-and-spring microphones, such as this Western Electric microphone, were common during the electrical age of sound recording c. 1925–45.. The second wave of sound recording history was ushered in by the introduction of Western Electric's integrated system of electrical microphones, electronic signal amplifiers and electromechanical recorders, which was adopted by major US record labels in ...
David Edward Hughes (16 May 1830 – 22 January 1900), was a British-American inventor, practical experimenter, and professor of music known for his work on the printing telegraph and the microphone. [3] He is generally considered to have been born in London but his family moved around that time so he may have been born in Corwen, Wales. [4]
Dr Harry Ferdinand Olson, E.E., Ph.D. (December 28, 1901 – April 1, 1982) was a prominent engineer and inventor with RCA Victor, the Acoustic Research Director of RCA Laboratories, Princeton, and a pioneer in the field of 20th century acoustical engineering [1] notably in the fields of high-fidelity, digital music synthesis, microphones, loudspeakers, acoustics, radar, submarine ...
The condenser microphone, invented at Western Electric in 1916 by E. C. Wente, [22] is also called a capacitor microphone or electrostatic microphone—capacitors were historically called condensers. The diaphragm acts as one plate of a capacitor, and audio vibrations produce changes in the distance between the plates.
These included improved microphones and auxiliary devices such as electronic filters, all dependent on electronic amplification to be of practical use in recording. In 1906, Lee De Forest invented the Audion triode vacuum tube, an electronic valve that could amplify weak electrical signals. By 1915, it was in use in long-distance telephone ...

Shure 55S. The Shure 55SH is a professional cardioid dynamic microphone that has been commonly used in broadcast applications since 1939. Designed by American audio products company Shure, it has been described as "iconic" in pamphlets and reviews, [1] after the Elvis stamp issued by the U.S. Postal Service in 1993. [2]
He designed the Magnavox dynamic loudspeaker for reception of radio broadcasting in 1919. He also invented and patented, with Edwin S. Pridham, the first anti-noise self-neutralizing microphone in 1917 which allowed wireless communication between aircraft and the ground.
