Description
The analog MEMS microphones achieve excellent acoustic sensitivity and produce constant analog voltage signal, which makes them very versatile to be easily integrated into an extensive diversity of electronic designs. Calculated to fit into a small packaging gain, they care about valuable space of designing a modern product as well as maintain low power-consumption to increase battery life. These electro-acoustic transducer have a very good noise performance and the range of frequencies in use is very extensive which makes the recording of sound to be clear and natural in even the harsh environment.
The strong and sturdy building of the analog MEMS microphones has made them suitable in smartphone, wearable electronics, voice-based system, smart home devices, and Internet of Things activities, where sound sense and voice recognition are needed. They are highly sensitive, and consistent in sound quality hence allowing those developing them to ensure high quality audio experiences in both consumers and industrial products.
