Microphone array

A microphone array contains multiple microphone capsules whose outputs are electronically combined for directional recording of sound. The directivity and frequency characteristics of the microphone array depend on the number and position of the microphone capsules. In order to obtain the smallest possible microphone array with only a small number of microphone capsules, with nearly uniform directivity and frequency dependence over the audio frequency range, but which is scalable and robust to small mispositioning of the capsules. Microphone arrays with 15 or 21 microphone capsules (K 15,11 ~K 15,35 ,K 21,11 ~K 21,37 ) are arranged on a carrier (T, T') that are located on three similar branches, each branch being provided with the same number of microphone capsules, which are rotated by 120° with respect to each other. Each of the microphone capsules is located at a triangular corner of the L2 grid in a planar isometric coordinate system (forming an equilateral L2 grid) with three axes (L0, L1, L2) that are rotated by 120° with respect to each other.

Microelectromechanical systems (MEMS) transducers for high sound pressure level (SPL) measurements

PCT designated stageWO2026107059A1MicrophonesSemiconductor electrostatic transducersTransducerEngineering
Aspects of the disclosure relate to microelectromechanical systems (MEMS) devices for pressure measurements. In particular, various examples herein describe techniques for limiting a diaphragm displacement of capacitive MEMS transducers to enable high sound pressure level (SPL) measurements. A reduced diaphragm displacement may be achieved by using a cap over the diaphragm of the MEMS transducer to reduce a volume of a back cavity of a MEMS transducer. A smaller back cavity may acoustically load the diaphragm and reduce the diaphragm displacement. Additionally, or alternatively, a reduced diaphragm displacement may also be achieved by stacking multiple MEMS transducers over each other such that the multiple MEMS transducers are in series acoustically.
