FPC (Flexible Printed Circuit) connecting type MEMS (Micro-Electro-Mechanical-System) microphone
2011
The utility model discloses an FPC (Flexible Printed Circuit) connecting type MEMS (Micro-Electro-Mechanical-System) microphone. The FPC connecting type MEMS microphone comprises an ASIC (Application Specific Integrated Circuit) chip, an MEMS chip, an FPC and a shell, wherein the FPC is electrically connected with the ASIC chip and the MEMS chip, and the shell is combined with the FPC to form a containing space which is used for containing the ASIC chip and the MEMS chip. The FPC connecting type MEMS microphone is characterized in that the FPC comprises a hardness strengthening part, the ASIC chip, the MEMS chip and the shell which is arranged on the hardness strengthening part. Compared with the prior art using a PCB, the FPC connecting type MEMS microphone disclosed by the utility model has the advantages that the product height can be effectively reduced, the sensitivity of a microphone can be increased, and the cost can be saved.
