Abstract
An on/off head detection system uses magnetic field intensity to determine a configuration, position and/or orientation of a headphone, including whether a headphone is on or off a wearer's head. The system includes a magnetic field sensor configured to detect a magnetic field emitted by a magnetic field source associated with an earpiece of the headphone. A control module determines an intensity of the magnetic field and whether the intensity of the magnetic field has reached a threshold. An operational mode associated with the headphone or an associated device is performed in response to the intensity of the magnetic field reaching the threshold.
Claims26
A method comprising:
- receiving, in a first earpiece of a headphone, a magnetic field emitted by a magnetic field source associated with a second earpiece of the headphone;
- determining an intensity of the magnetic field;
- determining whether the intensity of the magnetic field has reached a threshold;
- and
- in response to the intensity of the magnetic field reaching the threshold, performing an operational mode associated with at least one of the headphone or a device in communication with the headphone.
An apparatus comprising:
- a magnetic field sensor positioned within a first earpiece of a headphone and configured to detect a magnetic field emitted by a second earpiece of the headphone;
- a control module configured to:
- determine an intensity of the magnetic field;
- determine whether the intensity of the magnetic field has reached a threshold;
- and
- in response to the intensity of the magnetic field reaching the threshold, perform an operational mode associated with at least one of the headphone or a device in communication with the headphone.
A headphone system comprising:
- a first acoustic transducer of a headphone;
- a second acoustic transducer of the headphone;
- a magnetic field sensor configured to detect a magnetic field emitted by at least one magnet associated with the first acoustic transducer or the second acoustic transducer;
- a control module configured to:
- determine an intensity of the magnetic field;
- determine whether the intensity of the magnetic field has reached a threshold;
- and
- in response to the intensity of the magnetic field reaching the threshold, perform an operational mode associated with at least one of the headphone or a device in communication with the headphone.
