Cupertino, CA (August 14, 2025)—As Apple continues to ramp up film and TV production, the company has won a U.S. patent for a dual concentric spherical microphone array.

Apple engineers filed the patent which is titled “Apple Dual Concentric Spherical Microphone Array” for film production, Vision Pro content and more. The literature describes a 3D mic system comprising an inner sphere with mic elements distributed evenly across its surface with an outer shell, shaped like a dodecahedron (12 sides), fitted with a microphone at each vertex.

Tiny, efficient MEMS microphones are used in pairs for precision, and all microphones are positioned equidistant from the center for balanced sound capture. Optional accessories will include a wind shield and mounting shaft.

The outer frame can be 3D-printed as a single unit using additive techniques, according to the patent.
