Abstract
An example embodiment includes a playback device comprising a wireless communications interface including a wireless (e.g., a radio frequency (RF) antenna), a capacitive sensor comprising an electrode that is coupled to the RF antenna, one or more processors, and a data storage having stored therein instructions executable by the one or more processors to cause the playback device to perform operations. The operations include operating the playback device in a first power state, detecting that an object is in proximity to the capacitive sensor, and in response to detecting the object, adjusting operation of the playback device from the first power state to a second power state.
Claims21
1-20. (canceled)
A wireless headphone device comprising:
- a wireless communications interface including a wireless antenna;
- at least one infrared sensor;
- an audio amplifier that is configured to drive a transducer;
- at least one processor;
- and
- at least one non-transitory computer-readable medium comprising program instructions that are executable by the at least one processor such that the wireless headphone device is configured to:
- operate in a first power state;
- detect, using an output of the at least one infrared sensor, presence of a user;
- after detecting the presence of the user, adjust operation of the wireless headphone device from the first power state to a second power state;
- and
- while the wireless headphone device is operating in the second power state:
- stream, via the wireless antenna, data representing audio content;
- and
- play back the audio content via the audio amplifier and the transducer.
A playback device comprising:
- a wireless communications interface;
- one or more processors;
- at least one infrared sensor;
- an audio amplifier that is configured to drive a transducer;
- and
- at least one non-transitory computer-readable medium having stored thereon instructions executable by the one or more processors to cause the playback device to perform functions comprising:
- operate in a first power state;
- detect, using an output of the at least one infrared sensor, presence of a user;
- after detecting the presence of the user, adjust operation of the playback device from the first power state to a second power state;
- and
- while the playback device is operating in the second power state:
- stream, via the wireless communications interface, data representing audio content;
- and
- play back the audio content via the audio amplifier and the transducer.
A method comprising:
- operating a wireless playback device in a first power state, the wireless playback device including at least one infrared sensor, an audio amplifier, and a transducer;
- using the at least one infrared sensor to detect presence of a user in proximity of the wireless playback device;
- after detecting the presence of the user, adjusting operation of the wireless playback device from the first power state to a second power state;
- and
- while the wireless playback device is operating in the second power state:
- stream data representing audio content to the wireless playback device;
- and
- play back the audio content via the audio amplifier and the transducer.
