Development history of microphone 40 microphone (also known as microphone and microphone, the official Chinese name is microphone) is a transducer that converts sound into electronic signals. The history of microphone can be traced back to the end of the 19th century. Scientists such as Alexander Graham Bell are committed to finding better ways to pick up sound, so as to improve the latest invention at that time - telephone. During this period, they invented liquid microphone and carbon particle microphone. The effect of these microphones is not ideal, but they can barely be used. In the 20th century, microphones developed from resistance conversion to inductive and capacitive conversion. A large number of new microphone technologies gradually developed, including aluminum tape, moving coil and other microphones, as well as capacitive microphones and electret microphones widely used at present.
