Abstract
A headset for wireless communicating with a personal electronic device, such as a wireless phone, provides audio output based on an audio signal from the personal electronic device. A secondary battery in the headset provides power for the headset and is rechargeable from a primary battery in the personal electronic device, thereby allowing the user to recharge the headset in the field. Alternatively two secondary batteries may be provided. One of the secondary batteries can be used to power the headset, while the other is connected to the personal electronic device for recharging from the primary battery. When the battery in the headset becomes depleted, the batteries are exchanged.
Claims19
A personal electronic device outputting an audio signal comprising:
- a primary rechargeable battery located in said personal electronic device;
- a headset for providing wireless communication with said personal electronic device for transducing said audio signal into audible sound;
- a secondary rechargeable battery located in said headset for powering the headset;
- a headset charger disposed in said headset for recharging said secondary rechargeable battery from said primary rechargeable battery;
- an additional rechargeable secondary battery, said secondary rechargeable battery and said additional secondary rechargeable battery being interchangeable in connection to either said headset or said personal electronic device;
- and
- an internal charger disposed in said personal electronic device for charging either said secondary rechargeable battery or said additional secondary rechargeable battery from said primary rechargeable battery, said internal charger charging whichever secondary rechargeable battery is housed in said personal electronic device.
A method of powering a personal electronic device that outputs an audio signal, the method comprising:
- recharging a secondary battery located in a headset from a primary battery located in said personal electronic device, wherein said headset provides wireless communication with said personal electronic device for transducing said audio signal as audible sound;
- providing an additional secondary battery, wherein said secondary battery and said additional secondary battery are interchangeable in connection to either said headset or said personal electronic device and are sized to be housed inside the personal electronic device;
- locating an internal charger in said personal electronic device for charging either said secondary battery or said additional secondary battery;
- and
- charging whichever secondary battery is housed inside said personal electronic device.
A personal electronic device outputting an audio signal comprising:
- a primary rechargeable power means for powering said personal electronic device;
- a headset for providing wireless communication with the personal electronic device, said headset having means for transducing said audio signal into audible sound;
- a secondary rechargeable power means located in the headset for powering the headset;
- a headset charging means disposed in said headset for recharging said secondary rechargeable power means from said primary power means;
- an additional secondary rechargeable power means, said secondary rechargeable power means and said additional secondary rechargeable power means being interchangeable in connection to either said headset or said personal electronic device and are sized and adapted to be housed inside said personal electronic device;
- and
- an internal charging means disposed in said personal electronic device for charging either said secondary rechargeable power means or said additional secondary rechargeable power means, said internal charging means charging whichever secondary rechargeable power means is housed inside said personal electronic device.
