Multipoint membrane divider for condenser microphone capsules uses multiple spacers to separate a membrane into multiple areas

摘要

Attached on a back-plate electrode (5) for condenser microphone capsules, multiple spacers (2) divide a membrane (1) into multiple small areas. The membrane's surface is divided into multiple membrane surfaces that permit an amplification in a frequency response upwards. The membrane is supported by the spacers at multiple points.
