As part of our special feature on ribbon mics this week, we're taking a trip through the microphone's early days — from invention to old-school broadcasting. Enjoy these historic photos of a time when recorded and amplified audio were a novelty, rather than a necessity of everyday life. Above: Carbon-Button Microphone This drumlike device is a carbon-button microphone, patented by Emile Berliner in 1877. It was one of the first ever created and by far the most usable. Berliner is credited with inventing the carbon-button microphone in 1876. Though there were other microphone technologies in existence, Berliner’s design was more robust than the rest (including a liquid-based mic invented by Alexander Graham Bell). Bell himself was so impressed with the carbon-button that he bought the rights from Berliner for $50,000 (1.1 million dollars in today's money), so he could use it in his telephone prototypes. Berliner called his microphone a “loose-contact transmitter” because it was composed of two electrical contacts separated by a thin layer of carbon. The “loose” contact was attached to a diaphragm that vibrated when struck by a sound wave. The other was connected to the output. Unfortunately for Berliner, his patent didn’t survive a legal challenge, which resulted in an 1892 ruling by the U.S. Supreme Court ruling that gave the credit to Thomas Edison. In fact, neither Berliner nor Edison could rightfully claim full credit for the carbon-button mic. The idea for it had been around for years before they began their experiments, though it had never been perfected.

Emile Berliner sits in front of his carbon-button microphone. In certain configurations, carbon-buttons can behave as if they have built-in amplifiers, not only converting sound into voltage but also increasing the strength of that voltage before it leaves the mic. The crude transmitters of the teens and '20s required high-input signals in order to function. Vacuum tubes were new and not in widespread use, and transistors were far in the future. So powerful carbon-buttons were a must.

Mouthpiece Luxury An early carbon-button microphone created by Emile Berliner sits on the left. On the right is a mouthpiece that could be attached to it — as part of the luxury-option package.

“Ultra-Audible” Microphone Phillips Thomas invented an “ultra-audible” microphone in the 1920s, while working for Westinghouse Electric. The name derived from Thomas’ claim that the device was sensitive enough to detect vibrations outside the range of human hearing. Popular Science Monthly speculated in April 1924 that Thomas’ microphone could determine “ultra-audible” bug songs not heard by humans into electrical signals and then light, allowing human observers to analyze the sounds even though they couldn’t hear them. Thomas’ microphone seems humdrum in light of his other inventionary ambitions. His “vortex gun” was intended to replace conventional smokestacks and diminish low-hanging smog by forming emissions into gigantic smoke rings and blasting them into the stratosphere. He was also engaged in searching for a means of distributing electric power by radio, and believed that mental telepathy might be achieved by using the appropriate electromagnetic frequencies. Thomas supplemented his practical research with a contribution to the world’s musical culture, the photoelectric marimba, an instrument controlled by flashlights.

Dictaphone The hookah-like tube connects this anonymous businessman to a dictaphone, the first technology for nonprofessional recording, used primarily in offices to take dictations. Invented by Thomas Edison, the dictaphone uses the same basic principle as a phonograph. Sound vibrates a needle inside the device that cuts a groove into a rotating blank format — in this case a wax cylinder. The cylinder can be played back to reproduce the original sound, and though the quality of audio is horrible, indie bands in search of vintage cred are predicted to release wax-cylinder singles in the near future.

WMAQ Before the creation of the Federal Radio Commission (precursor of the FCC) in 1927, radio was largely unregulated. Starting a station was simply a matter of purchasing a transmitter and an antenna. Chicago-based AM radio station WMAQ went on the air in 1922 and continued operating until 2000. Many early stations owned by retailers or newspapers, and WMAQ was owned by one of each: the Fair Department Store and the Chicago Daily News. The station transmitted from inside the store itself, serving as a long-form advertisement and novelty attraction. The Daily News publishers quickly saw that radio would become a major force in the media, and bought out their partners. In the picture above, a then-standard carbon-button mic is suspended in a shock mount: a set of springs that absorb vibrations that might otherwise be picked up by the microphone.

Hal Totten and Ty Cobb Hal Totten, who called games for Chicago’s WMAQ during the 1920s, wears a three-piece suit in Comiskey Park. He stands next to Ty Cobb and fellow big-leaguers Eddie Collins and Bill Hunnefield at a game in 1927. The group is speaking into an early carbon-button microphone which served the crucial dual purpose of transmitting sound and amplifying it. The amplification was essential during the first days of broadcasting, because transmitters weren’t sensitive enough to pick up the output of unamplified microphones.

Tom Mix Actor Tom Mix accepts the limp handshake of an unidentified youth at Chicago's WMAQ in 1929. Mix was a superstar of the first years of movie melodramas. His portrayal of clean-cut cowboy heroes created an enduring Hollywood archetype that lasted into the era of John Wayne, and earned Mix a place on the cover of Sergeant Pepper’s Lonely Hearts Club Band. He later lent his name to a popular radio program, The Tom Mix Ralston Straight Shooters, but never had a part on the show. Throughout its run from 1933 to 1950, Mix was nominally the star while the “Tom Mix” character was actually played by other actors. Mix, in fact, died in 1940.
