What Is a Ribbon Microphone?

Ribbon Microphone (Ribbon Microphone) is a dynamic microphone using the principle of electromagnetic induction. Between the two poles of the magnet is placed a band-shaped metal film, usually aluminum or Dura aluminum. When this film is shaken by sound, it is caused by electromagnetic induction. And the signal.

The aluminum ribbon microphone is a thin, usually wrinkled or wavy aluminum ribbon film, placed between the two poles of the magnet, the film is parallel to the magnetic lines of force, and the two ends are fixed to an insulating frame in order to remove the induced signal. When the film vibrates with sound waves, the magnetic field lines are cut to produce

The earliest ribbon microphone was invented by German physicist Dr. Walter H. Schottky and Dr. Erwin Gerlach in the early 1920s. They also used this circuit in reverse and invented the earliest ribbon type

A microphone (also known as a microphone or microphone , the official Chinese name is a microphone ), translated from the English microphone , is a transducer that converts sound into electronic signals.

Are listed in the microphone specifications

Electromagnetic induction ) Means that the conductor placed in the changing magnetic flux will generate electromotive force. This electromotive force is called induced electromotive force or induced electromotive force . If the conductor is closed into a loop, the electromotive force will drive electrons to form an induced current ( induced current ).

Michael Faraday was generally believed to have discovered the induction phenomenon in 1831, although Francesco Zantedeschi's work in 1829 might have foreseen this. Faraday found that the electromotive force generated on a closed loop is directly proportional to the rate of change of magnetic flux through any curved surface surrounded by the path, which means that when the magnetic flux through the curved surface surrounded by a conductor changes, current will flow in any closed conductor . This applies when the magnetic field itself changes or when the conductor moves in the magnetic field. Electromagnetic induction is the basis for the operation of generators, induction motors, transformers, and most other electrical equipment. ^[2]
