A feasible solution is to use capacitive scheme to manufacture micro microphone. The advantage of this method is that all materials used in the integrated circuit manufacturing process can be used in the manufacture of sensors. However, it is very difficult to manufacture micro microphone by single chip process, because there can only be a small space between the two capacitor plates. Moreover, due to the limitation of size, the bias voltage is difficult to meet in some applications. Based on the above problems, the research on capacitive microphone has not been interrupted [3].
voiceAt the beginning of the 20th century, microphones developed from resistance conversion to inductive and capacitive conversion. A large number of new microphone technologies gradually developed, including microphones such as aluminum ribbon moving coil, as well as capacitive microphones and electret microphones widely used at present.
