1. A playback device comprising:

  • a capacitive proximity sensor configured to detect physical movement in a first direction, wherein the capacitive proximity sensor includes a first metal electrode;

    a speaker grille on a surface of the playback device oriented at a relative angle to the capacitive proximity sensor, wherein the speaker grille is coupled to the first metal electrode of the capacitive proximity sensor such that the capacitive proximity sensor is further configured to detect physical movement in a second direction, wherein the second direction is substantially at the relative angle to the first direction;

    a processor; and

    memory having stored thereon instructions executable by the processor to cause the playback device to perform functions comprising;

    determining 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.
