摘要:
Embodiments are provided for intelligently revealing selectable icons on a control panel of a playback device based on proximity detection. In one example, an ambient light level may be determined based on a detection of ambient light by a light sensor of a control area for a playback device. Based on the ambient light level, a sensitivity of an infrared (IR) proximity sensor and a sensitivity of a capacitive proximity sensor may be adjusted. The IR proximity sensor and the capacitive proximity sensor may each be configured to detect a physical movement. Based on the detection of the physical movement by at least one of the IR proximity sensor and the capacitive proximity sensor, a physical approach of an entity towards the playback device may be determined, and a control area of the playback device may be illuminated.
摘要:
Example techniques involve a speaker grille of a playback device that is connectable to a capacitive proximity sensor, which may increase the area over which an object's proximity to the sensor can be sensed. An example implementation includes a playback device that includes an enclosure comprising a first surface and a second surface, one or more speakers mounted on the first surface, a conductive speaker grille covering the one or more speakers, one or more playback controls mounted on the second surface, and a capacitive proximity sensor oriented away from the second surface. The capacitive proximity sensor includes a grounding plate that is connectable to the conductive speaker grille.

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.
摘要:
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.
