摘要: Embodiments of a capacitive sensor configuration for proximity detection by playback device are provided. The may include configured to detect physical movement in first direction, and radio frequency (RF) antenna ground plane oriented at relative angle the sensor. metal electrode coupled RF is such that be further second direction substantially direction. determine based on sensor, approach an entity towards from one or more
