Microphone array housing with acoustic extending structure and electronic device utilizing the same

摘要

An electronic device is provided. The electronic device includes a case, a microphone array housing consists of a first acoustic extending structure, a second acoustic extending structure, an interface IC, a first membrane and a second membrane. The case includes a first acoustic opening and a second acoustic opening. The first acoustic extending structure is connected to the first acoustic opening. The second acoustic extending structure is connected to the second acoustic opening. The first membrane receives a first acoustic signal via the first acoustic opening and the first acoustic extending structure. The second membrane receives a second acoustic signal via the second acoustic opening and the second acoustic extending structure.
