Patent ID: 8670579

Claim:
A MEMS microphone, comprising: a cover; a housing engaging with the cover for forming a cavity, the housing comprising a base and a sidewall extending perpendicularly from the base; at least one MEMS transducer accommodated in the cavity, the transducer having a back volume; and a conductive case covering the cover and the sidewall of the housing for protecting the transducer against interference signals; wherein the conductive case defines a first part covering the cover, a second part extending from the first part for covering the sidewall and a third part perpendicularly extending from the second part for covering a periphery part of the base, the third part forming an opening; and wherein the cover is a printed circuit board, and the housing includes circuits embedded therein for electrically connecting with the cover; and wherein the cover defines a recess, and the sidewall of the housing defines a protrusion for engaging with the recess.
