Capacitive Proximity Sensor Configuration Including a Speaker Grille

摘要

An example embodiment includes a playback device that includes a capacitive proximity sensor; one or more speakers; a conductive speaker grille; and a control system that decouples a grounding plane of the capacitive proximity sensor from the conductive speaker grille while the one or more speakers are rendering audio and couples the grounding plane of the capacitive proximity sensor to the conductive speaker grille while the one or more speakers are not rendering audio.
