Systems and methods for enhancing performance of a microphone

摘要

Systems and methods for enhancing performance of a microphone are disclosed. An airflow control system may include a block-shaped structure and an airflow impedance element residing within a cavity of the block-shaped structure. The airflow impedance element may be formed by filling the cavity with a plurality of pre-processed airflow impedance elements and sintering these elements, and may include a plurality of non-linear pathways. The plurality non-linear pathways may both impede airflow therethrough (e.g., when a force exerted by the airflow exceeds a predetermined amount) and pass sound that may match a frequency response of a microphone without substantially affecting the amplitude and frequency characteristics of the sound.

1. An airflow control system for controlling airflow toward a microphone of an electronic device, the airflow control system comprising:
a planar block-shaped structure bonded between an aperture in an outermost surface of the electronic device and the microphone, comprising a passageway, the passageway comprising:
a first opening configured to align with the aperture in the outermost surface of the electronic device; anda second opening configured to align with an aperture of the microphone; and airflow impedance elements disposed within the passageway and sintered together to form a single structure that is secured within the passageway by a shape of sidewalls defining the passageway, the airflow impedance elements being constructed to control the airflow from the aperture in the outermost surface of the electronic device to the aperture of the microphone.
