There are so many kinds and types of microphones out there. They all vary in sizes, prices, features as well as specifications. In terms of categorization according to built, there are actually three (3) major classifications of microphones. These classifications are the condenser, the dynamic and the ribbon microphone. They have their own characteristics and specifications that you need to understand.
Now, when it comes to understanding one of kind of microphone, specifically the ribbon microphone, you need to know first some of the most basic and essential information about this kind. If you will ask me, I have found out by reading lots of related articles that the basic things you need to understand about this kind are its history, operational principle as well as the advantages and disadvantages of using the said kind of microphone.
On the one hand, the history of the ribbon microphone tells us the major phases of its developments. It was actually in the early years of the 1920s when two (2) doctors namely Dr. Walter Schottky and Dr. Erwin Gerlach jointly discovered the first ever ribbon microphone. Later that decade, another doctor began developing the said type of microphones using the field of coils as well as permanent magnets later on.
However, it was only in 1931 when its production started. During those times, the said kind of microphone introduced a breakthrough to the audio recording as well as broadcasting industry. It is actually one of the first breakthroughs that introduced a new standard when it comes to frequency response. Moreover, the clarity of the sound it produces as well as the realistic quality of the sound cannot be matched by any kind of microphones out there then.
Jumping to several decades after, the ribbon microphone has been developed further in 2007. During that time, a new kind of ribbon microphones was introduced to the market, which is made from strong nano-materials and technologies. It is again another milestone for the said type of microphone because it offered orders of improvement in the magnitude when it comes to signal purity as well as quality of output.
On the other hand, after knowing its basic history and milestone, I know that you are already wondering how it really works. In general sense, the ribbon microphone is called as such because it uses a very thin aluminum or a nanofilm kind of ribbon. This material is placed between the poles of the magnet incorporated in the system in order to generate voltage through the concept of electromagnetic induction.
In this kind of microphone, a current will be induced to the right angles relative to the ribbon velocity as well as the direction of the magnetic field. The said ribbon that I have mentioned above will vibrate because of the sound pressure. This will undergo several technical process that will produce the pickup patter of the microphone.
Lastly, aside from understanding the history and technicalities of the ribbon microphone, you also need to know its advantages and disadvantages. When it comes to the positive side of this kind, it is well known for its ability to produce high quality of recording details. However, it is too vulnerable and fragile compare to other kinds of microphones that you can see out there.
