Abstract
Systems and methods for wirelessly powering wearable audio playback devices are disclosed. Such a system can include a wearable audio playback device including a first earcup carrying a first audio transducer and a second earcup carrying a second audio transducer, the first earcup and the second earcup coupled together via a headband, an ear cushion configured to be removably coupled to the first earcup, and a wireless power receiver disposed within the ear cushion. A separate wireless charging device includes an energy storage component and a wireless power transmitter configured to wirelessly supply energy to the wireless power receiver.
Claims20
A system comprising:
- a wearable playback device configured to be worn over an ear of a user, the wearable playback device comprising:
- a first earcup carrying a first audio transducer and a second earcup carrying a second audio transducer, the first earcup and the second earcup coupled together via a headband;
- an ear cushion configured to be removably coupled to the first earcup;
- and
- a wireless power receiver disposed within the ear cushion, the wireless power receiver configured to supply electrical energy for operation of the first audio transducer;
- and
- a wireless charging device configured to supply energy to the wearable playback device, the wireless charging device comprising:
- an energy storage component;
- and
- a wireless power transmitter configured to wirelessly supply energy to the wireless power receiver.
A wearable playback device comprising:
- a first earcup carrying a first audio transducer;
- a second earcup carrying a second audio transducer;
- a headband coupling the first earcup and the second earcup;
- an ear cushion configured to be removably coupled to the first earcup;
- and
- a wireless power receiver disposed within the ear cushion, the wireless power receiver configured to (i) receive electrical energy from an external wireless power transmitter device, and (ii) supply electrical energy for operation of the first audio transducer.
A system comprising:
