Publication number: 20240171915Abstract: Aspects of the subject technology relate to electronic devices having speakers such as microelectromechanical systems (MEMS) speakers. A MEMS speaker can include an electrostatically driven, corrugated MEMS structure to move air without a magnet, coil, or traditional speaker membrane, and thus provide a low-power, compact speaker with a large acoustically active area in a small volume. Neighboring folds in the corrugated MEMS structure may form pairs of MEMS electrodes that can be pushed together and/or pulled apart to deform the MEMS structure in a breathing motion that generates pressure differentials on opposing sides of the corrugated MEMS structure to generate sound. Additional modes of operation are described.Type: ApplicationFiled: January 31, 2024Publication date: May 23, 2024Inventors: Gokhan HATIPOGLU, Onur I. ILKORUR, Pablo Seoane VIEITES, Christopher WILK, Peter C. HRUDEY

Publication number: 20240121559Abstract: Aspects of the subject technology relate to electronic devices having speakers such as microelectromechanical systems (MEMS) speakers. A MEMS speaker can include cylindrical corrugated MEMS structure. The cylindrical corrugated MEMS structure may include a contiguous MEMS structure with corrugations that run around an open cylindrical core that is defined, in part, by interior folds of the corrugations. The cylindrical corrugated MEMS structure may be deformed, responsive to an applied voltage, such that a portion of the cylindrical corrugated MEMS structure bends into and/or out of the open cylindrical core to push air out of and/or pull air into the open cylindrical core. In one or more implementations, a MEMS speaker may include an array of cylindrical corrugated MEMS structures.Type: ApplicationFiled: August 28, 2023Publication date: April 11, 2024Inventors: Onur I.

Patent number: 11317199Abstract: An electronic device has an acoustic transducer with an acoustic diaphragm. The diaphragm has opposed first and second major surfaces. A front volume is positioned adjacent the first major surface. A back volume is positioned adjacent the second major surface. An elongated channel defines a barometric vent and extends from a first end fluidly coupled with the front volume to a second end fluidly coupled with the back volume, fluidly coupling the front volume with the back volume. The elongated channel may have a high aspect ratio (L/D), providing the vent with a substantial air mass. The elongated channel may be segmented to define a higher-order filter. For example, a segmented channel can have a cascade of repeating acoustic-mass and acoustic-compliance units, providing the barometric vent with additional degrees-of-freedom for tuning.Type: GrantFiled: May 21, 2020Date of Patent: April 26, 2022Assignee: Apple Inc.Inventors: Peter C.
