Abstract
Embodiments of a capacitive sensor configuration for proximity detection by a playback device are provided. The playback device may include a capacitive proximity sensor configured to detect physical movement in a first direction, and a speaker grille on a surface of the playback device oriented at a relative angle to the capacitive proximity sensor. The capacitive proximity sensor includes a first metal electrode coupled to the speaker grille such that the capacitive proximity sensor may be further configured to detect physical movement in a second direction that is substantially at the relative angle to the first direction. The playback device may be configured to determine based on a detection of physical movement by the capacitive proximity sensor, a physical approach of an entity towards the playback device from one or more of the first direction and the second direction.
