Microphone e.g. semiconductor-condenser microphone, for use in mobile phone, has membrane structure with boundary region, which is not movable due to pressure, on which carrier is attached, where region and opposing structure have recesses

摘要

The microphone has a membrane structure (11) arranged at a distance from an opposing structure (16), where an electrical capacitance between the structures depends on pressure. The structure (11) has a boundary region, which is not movable due to the pressure, on which a membrane carrier (6) is attached. The region and the structure (16) have recesses that are spaced apart from one another so that a bar is formed between the recesses. An independent claim is also included for a method for manufacturing a microphone.
