Abstract
A system may include at least one audio transducer and a controller. The controller may generate at least one actuation signal. The at least one actuation signal may drive the at least one audio transducer such that the at least one audio transducer generates evanescent wave audio signals in proximity to a wearer's ear. The evanescent wave audio signals may decay in strength with distance from the at least one audio transducer. Various other apparatuses, systems, and methods are also disclosed.
Claims20
A system comprising:
- at least one audio transducer disposed within a virtual or augmented reality headset;
- and
- a controller, wherein:
- the controller generates at least one actuation signal;
- the at least one actuation signal drives the at least one audio transducer such that the at least one audio transducer generates evanescent wave audio signals in proximity to an ear of a wearer of the headset;
- the evanescent wave audio signals decay in strength with lateral distance from the at least one audio transducer;
- and
- the decaying of the evanescent wave audio signals increases a level of privacy protection for the wearer of the headset.
A device comprising:
- at least one audio transducer disposed within a virtual or augmented reality headset;
- and
- a controller, wherein:
- the controller generates at least one actuation signal;
- the at least one actuation signal drives the at least one audio transducer such that the at least one audio transducer generates evanescent wave audio signals in proximity to an ear of a wearer of the headset;
- the evanescent wave audio signals decay in strength with lateral distance from the at least one audio transducer;
- and
- the decaying of the evanescent wave audio signals increases a level of privacy protection for the wearer of the headset.
A method comprising:
- disposing at least one audio transducer within a wearable device comprising a virtual or augmented reality headset;
- providing a controller;
- and
- connecting the at least one audio transducer to the controller, wherein:
- the controller generates at least one actuation signal;
- the at least one actuation signal drives the at least one audio transducer such that the at least one audio transducer generates evanescent wave audio signals in proximity to an ear of a wearer of the headset;
- the evanescent wave audio signals decay in strength with lateral distance from the at least one audio transducer;
- and
- the decaying of the evanescent wave audio signals increases a level of privacy protection for the wearer of the headset.
