Apple had two patents in 3D printing during Q4 2023. Apple Inc filed a patent for a multi-radius spherical microphone with inner and outer bodies, each containing an array of microphones positioned equidistant from the center. Another patent describes a head-mounted display with a catadioptric optical system, including a single lens element with a retarder coated on a curved surface, allowing for components to be formed using direct printing techniques for improved alignment and reduced layers.

Application: Apple dual concentric spherical microphone array (Patent ID: US20230396921A1)
The patent filed by Apple Inc. describes a multi-radius spherical microphone array that includes an inner body with an array of inner microphones and an outer body in the shape of a dodecahedron with an array of outer microphones. The outer microphones are positioned radially equidistant from the center, and the outer body may be fabricated using a 3D printing process, with rigid arms defining the edges of the dodecahedron.
The microphone array also includes a mounting shaft extending through the outer body, support struts connecting the outer body to the mounting shaft, and a wind shield surrounding the microphones. The microphones in the array are evenly distributed across the inner spherical body, with each microphone being a MEMS microphone. The outer body is described as a unitary structure with joint structures at the vertices of the dodecahedron. Overall, the design of the multi-radius spherical microphone array allows for precise and consistent audio capture from various directions.
