Where was the Microphone invented?

The Invention of Microphone: A Brief History

The invention of the microphone paved the way for a revolution in communication and recording. Without the microphone, we might not have had the technology to make a phone call or record a song. The invention of the microphone dates back to the early 19th century, with the first microphone designs being acoustic in nature. These early designs were made using various materials, including thin metal sheets, stretched animal skin, and carbon granule.

Early Designs of Microphones

The earliest designs of microphones were simple devices that could pick up and amplify sound waves. In 1827, Sir Charles Wheatstone filed the patent for his "membrane" microphone, which used a thin metal sheet that vibrated in response to sound waves. Over the next few decades, several other inventors improved upon Wheatstone's design, using different materials to create more sensitive microphones.

One such inventor, Emile Berliner, patented the first practical microphone in 1877. Berliner's design used a thin metal diaphragm that vibrated in response to sound waves, which was then amplified by a coil of wire. Berliner's microphone was much more reliable than previous designs and soon became the standard for telephones and other communication devices.

The Carbon Microphone

One of the most important innovations in early microphone technology was the carbon microphone. Patented by David Edward Hughes in 1878, the carbon microphone used carbon granules to amplify sound waves. This design was much more sensitive than previous models and allowed for clearer recording and transmission of speech and music. The carbon microphone was used extensively in early radio and telephone systems and was the standard for recording and audio amplification until the mid-20th century.

The Dynamic Microphone

The dynamic microphone, also known as the moving-coil microphone, was invented in 1923 by Walter H. Schottky. Unlike previous designs, which used carbon granules or other materials to amplify sound waves, the dynamic microphone used a coil of wire to generate an electrical signal. The dynamic microphone was more rugged and reliable than earlier models and was ideal for use in live performances and broadcasting.

Another important innovation in microphone technology was the ribbon microphone, invented by Dr. Walter J. Schottky in 1925. The ribbon microphone used a thin ribbon of metal suspended in a magnetic field to pick up sound waves. This design was highly sensitive and became popular for recording music and broadcasting live performances.


From acoustic designs to carbon and dynamic microphones, the evolution of microphone technology has been essential to modern communication and entertainment. Today, we have a wide range of microphones with varying sensitivity, frequency response, and directional characteristics, allowing us to capture sound with incredible precision and clarity. The microphone remains an essential tool in modern life, from making phone calls to recording music and capturing the sounds of nature.

The Early History of the Microphone

Early Sound Amplification Devices

Before the microphone was invented, people relied on various sound amplification devices. One of the earliest devices was the ear trumpet, which was essentially a cone-shaped object that was held up to the ear to amplify sound. Another device was the speaking tube, which was a long tube that allowed people to communicate over distances.

The First Microphone

In the late 1800s, Alexander Graham Bell and his assistant, Thomas Watson, were working on improving the telephone. They wanted to find a way to transmit sound over longer distances without losing quality. This led to the invention of the first practical telephone transmitter, which could also be used as a microphone. The device was made up of a metal diaphragm that vibrated in response to sound waves. These vibrations were then converted into electrical signals that could be transmitted over the telephone wire. This groundbreaking invention revolutionized communication and paved the way for future developments in audio technology.
