AI Technical Summary

Technical Problem

Multi-microphone systems require a large number of separate acoustic channels and sound ports, leading to increased size and packaging constraints, which limits their usability due to the need for multiple couplings to the ambient environment.

Method used

The implementation of shared acoustic channels and sound ports allows multiple acoustic sensor devices to share channel portions and sound ports, reducing the total number of channels and ports required, thereby minimizing the physical space and footprint of the system.

Benefits of technology

This configuration enables the integration of multiple microphones into end-product devices with fewer sound ports, reducing manufacturing costs and maintaining directional sensitivity patterns, while allowing for more compact designs.

Abstract

An acoustic system includes a plurality of acoustic sensor devices, including at least a first acoustic sensor device and a second acoustic sensor device. The acoustic system also includes a plurality of acoustic channels, including at least a first acoustic channel configured to provide a first coupling, the first coupling being between the first acoustic sensor device and an ambient medium, and a second acoustic channel configured to provide a second coupling, the second coupling being between the second acoustic sensor device and the ambient medium. The first acoustic channel and the second acoustic channel may include a shared channel portion that includes at least a portion of the first acoustic channel that is common with at least a portion of the second acoustic channel.
