Silicon Microphone is a MEMS microphone. It's a microphone based
on MEMS technology. MEMS is also divided into analog and digital Microphone,
circuit output analog signal, digital signal silicon microphone --- referred to
as digital silicon microphone, the essential difference is that the ADC
conversion chip inside, which has higher integration, direct output of digital
signal, lower sensitivity, higher signal-to-noise ratio, wide application
range, can be used in hearing aids, electronic ears; In the computer
communication industry can be applied to mobile phones, digital cameras,
hands-free earpieces, notebook computers, etc. With the rapid development of
the electronic industry and the progress of the manufacturing process and
packaging technology, the design of microphone products is more towards the
demand for multi-function. To achieve the demands of short, small, light, thin,
power-saving, and cheap, we must develop a micro microphone which can be
integrated with chips made by a semiconductor process. This is a major trend of
microphone development in the future.
