Wente while working at Bell Laboratories. Wente had been tasked with improving the audio quality for telephones but his innovations also enhanced the microphone. Litke, an electrical engineer with Educational Media Resources and San Jose State College invented and filed a patent for the first wireless microphone.
It was designed for multimedia applications including television, radio, and higher education. This set a new level of design for microphones in the future. The electret microphone offered greater reliability and higher precision at a lower cost and with a smaller size. It revolutionized the microphone industry, with almost one billion units manufactured each year.
A number of miniature mics were also developed during this decade. These microphones are still popular today. The trend for miniature mics continues with applications such as wearable devices, smart home, and automobile technology,. This allowed for greater control when editing and rendering sound.

Several examples of early carbon microphones contained in the Steele Vintage Microphone Collection are featured in the gallery below. Steele's collection contains at least one microphone used by the U. This later carbon microphone, pictured in Figure E4, is identical to those that were in use by the military for radio broadcasts during the s. This particular model was often referred to as the "candlestick" microphone.

Just a few years after the invention of the microphone, in , David Edward Hughes developed the microphone into a different model which was used for a long time. In , the vacuum tube amplifier was invented which increased the volume of devices such as microphones.
The next year, the condensation microphone was introduced by Edward Christopher Wente of Bell Laboratories. The device is also known as a capacitor or an electrostatic microphone.
He had aimed to improve the quality of audio in the microphone and to enhance it further. Soon after in , the commercial production of condenser microphones began. The first dynamic microphone was invented in by Western Electric.
After the development of radio broadcasting, ribbon microphones were invented to assist in broadcasting. New designs of microphones were being produced in An electret microphone came about in , invented by Bell Laboratories. It completely transformed the microphone industry as it offered greater reliability at a lower cost. In s, condenser and ribbon microphones were further improved to enhance the audio quality of sound systems.
