## Background
RELATED APPLICATION
The present application is a non-provisional patent application and claims priority benefit, with regard to all common subject matter, of earlier-filed U.S. provisional patent application titled “Hybrid Watch, Smart Phone and Integrated Bluetooth® Headset Designs for All Bluetooth® Capable Devices”, Ser. No. 61/783,198, filed Mar. 14, 2013, incorporated by reference in its entirety into the present document.


BACKGROUND
Bluetooth® is a wireless technology standard for exchanging data over short distances (using short-wavelength ultra high frequency radio waves in the industrial, scientific, and medical band from 2.4 to 2.485 GHz) from fixed and mobile electronic devices. Based upon this technology, the wireless Bluetooth® headset was developed to allow hands-free communication, audio, and other data with users' paired Bluetooth® capable devices. Electronic Bluetooth® capable devices and wireless Bluetooth® headsets are manufactured as discrete devices each with their own power inputs and separate power supplies for maintaining and recharging power. Since wireless headsets are not physically connected with their paired devices and are small in size, they can easily be lost or even damaged. Therefore, users are not able to store the headsets centrally with their pairing devices and are often required to carry or utilize more than one power adapter to maintain power for both.
SUMMARY
The present invention solves the above problems and provides a distinct advance in the art of wireless headsets, such as Bluetooth® technology, so wireless headsets will not have to be stored and charged separately from their paired electronic devices. In particular, the present invention provides integrated wireless headsets that can be compactly docked and centrally stored with an electronic device when not in use and readily removed for use. The invention also allows headsets to be charged with an electronic device via a single charger and input connection or individually via their own separate charging inputs, so users will no longer be required to charge both separately or carry more than one charger.
One embodiment of the invention is an integrated electronic system that broadly comprises an electronic device, a wireless headset, and a single charger. The electronic device may be a mobile or fixed device for communications, Internet connectivity, data transmission, music, gaming and computer related tasks. Examples of mobile devices include, but are not limited to, any wireless communication or audio device, mobile phone, smart phone, watch phone, gaming device, music player; mobile computing platform such as a tablet or laptop computer; car audio or entertainment system; accessory charger; and smart wear or wearable clothing that attaches to a device or charger such as a wrist or watch band. Examples of fixed devices include, but are not limited to, any home or office based device for communication, audio or other wireless headset; desktop computer; smart television or appliance; gaming system; entertainment receiver or sound system; home or office automation system; alarm system; and land line based phone system. One embodiment of the electronic device includes a docking port and a charging port. The docking port includes interior electrical contacts for contacting corresponding electrical contacts of the headset when the headset is in the docking port. Another embodiment of the electronic device does not include a docking port and utilizes the charging port and auxiliary ports for docking the headset. The charging port includes electrical contacts for contacting corresponding electrical contacts of the charger when the device is connected to the charger.
The wireless headset allows the user to listen to audio and to communicate without holding the electronic device up to his or her ear and includes a housing, a speaker, an earpiece, a microphone, a transceiver, a battery, and a set of electrical contacts. In one embodiment, the housing includes outer walls and a cover cooperatively defining an interior chamber. The speaker and the earpiece may be retracted into the interior chamber for safe storing. The cover may then be shifted to enclose the speaker and the earpiece within the interior chamber. The electrical contacts are configured to contact corresponding electrical contacts in the docking port of the electronic device when the headset is in the docking port.
The headset may be stowed in the docking port of the electronic device for protecting the headset and for keeping track of the headset when not in use. The headset battery may also be charged via the electronic device when the headset is stowed in the docking port. The headset battery will charge when the electrical contacts of the headset contact the corresponding electrical contacts in the docking port of the electronic device and when the electrical contacts of the charger contact the corresponding electrical contacts of the charger port of the electronic device. The headset may be retrieved from the docking port and the headset earpiece may be pulled out of the interior chamber when the user desires to listen or communicate via the headset. The headset may also be charged independently of the electronic device through its own charger input.
The charger is connectable to the charging port of the electronic device for charging the electronic device and the headset and includes a power cord for plugging into a wall outlet, a 12-volt outlet, or another power source and electrical contacts for plugging into the charger port. The charger charges the batteries of the headset and the electronic device by delivering power from the power source to the batteries. The power travels from the power source and through the power cord to the battery of the electronic device via its electrical contacts and the corresponding electrical contacts in the charger port of the electronic device. Additional power travels from the electrical contacts in the charger port and through the electrical contacts in the docking station of the electronic device and the corresponding electrical contacts of the headset to the battery of the headset.
Another embodiment of the invention is a headset that can be used with an electronic device that is not equipped with the docking port described above. This embodiment of the headset includes a housing, a speaker, an earpiece, a microphone, a transceiver, a battery, and male and female power input connectors. The headset may also include a stabilizer. The male connector allows the headset to be connected to a charging port of a conventional electronic device, such as a smart phone. The female connector allows a charger to be connected to the headset so that the headset and electronic device can be charged at the same time. The power is routed through the charger to the headset battery and carried through to charge the device battery simultaneously while the headset and the electronic device are connected together. The stabilizer is inserted into an auxiliary port of the electronic device and reinforces the connection between the headset and the electronic device.
Another embodiment of the invention is a wireless headset that includes left and right audio units. The audio units can be connected to each other when not in use and can be docked and charged via the electronic device or via the headset systems as described above.

Using the integrated wireless electronic system 10 and simultaneously charging the headset 14a and the electronic device 12 via the electronic device 12 will now be described in more detail.
The user may prepare the headset 14a for being worn by sliding, pivoting, or rotating the cover 40 to an open position, pulling the speaker 30 and/or the earpiece 32 out of the interior chamber 42 and/or twisting the earpiece 32 away from the housing 28 of the headset 14a to an extended position (FIG. 12). The user may then place or clip the earpiece 32 onto his or her ear or insert the earpiece 32 into his or her ear. The user may then turn the headset 14a on and/or sync the headset 14a with the electronic device 12 by pressing the input button 36 on the headset 14a. The headset 14a will then establish a wireless connection with the electronic device 12. The user may then talk into the microphone 34 and the transceiver of the headset 14a will transmit a signal representative of the user's voice to the electronic device 12. The transceiver will also receive signals representative of another person's voice, other audio or data, and the speaker 30 will broadcast the audio into the user's ear.
The batteries of the headset 14a and the electronic device 12 will need to be recharged periodically and may be charged simultaneously via the charger 16. The user may prepare the headset 14a for charging by removing the headset 14a from his or her ear, pushing and/or twisting the earpiece 32 towards the housing 28 of the headset 14a, pushing the speaker 30 and/or the earpiece 32 into a retracted position within the interior chamber 42, and shifting the cover 40 to the closed position so that the speaker 30 and the earpiece 32 are protected and compactly stored. In some embodiments of the headset 14a, shifting the cover 40 to the closed position exposes the electrical contacts 38 for connecting the headset 14a to the electronic device 12. The user then inserts the headset 14a into the hollow chamber 26 of the headset docking port 22 of the electronic device 12 so that at least a portion of the headset 14a is enclosed by the housing 18 of the electronic device 12. In some embodiments of the headset docking port 22, the headset 14a is completely received in the hollow chamber 26 of the headset docking port 22 when the headset 14a is docked. The electrical contacts 38 of the headset 14a will contact the corresponding electrical contacts of the headset docking port 22 of the electronic device 12 when the headset 14a is inserted into the headset docking port 22. The display screen 20 may indicate whether the headset 14a is properly connected to the electronic device 12. The headset 14a may also charge independently via a female power input if needed.
The user may then plug the first end of the charger 16 into a wall outlet or other power source and the second end of the charger 16 into the charger port 24 of the electronic device 12 so that the second set of contacts 64 of the charger 16 contact the corresponding contacts of the charger port 24 of the electronic device 12. The charger 16 will then simultaneously charge the batteries of the electronic device 12 and the headset 14a or directly power the electronic device 12 and the headset 14a. The display screen 20 may indicate whether the charger 16 is charging the headset 14a and the electronic device 12. When the headset battery is fully charged or when the user desires to use the headset 14a again, the user may remove the headset 14a from the hollow chamber 26 of the headset docking port 22 and may prepare the headset 14a for being worn as described above.
Using the alternative headsets 14b-11s substantially similar to using the headset 14a as described above except the user connects the connector of the headset 14b-i to the corresponding connector of the electronic device 12 or accessory when connecting the headset 14b-i to the electronic device 12. The user removes the headset 14b-i from the electronic device 12 by disconnecting the connector of the headset 14b-i from the corresponding connector of the electronic device 12 or accessory of the electronic device 12. For example, the grooves 46a,b of the headset 14c are aligned with and slid along corresponding ridges of the electronic device 12 to ensure that the headset 14 is properly docked with the electronic device 12. The resistively bendable tabs 48a,b of the headset 14d may be releasibly engaged by corresponding protrusions of the electronic device 12. The user may hook the elongated arm 50 of the headset 14e onto a corresponding loop of the electronic device 12 and disconnect the elongated arm 50 from the loop and push the elongated arm 50 into the interior chamber 42 of the headset 14e for wearing the headset 14e. 
The integrated wireless electronic system 10 provides many advantages over conventional wireless electronic systems. For example, the headset docking port 22 of the electronic device 12 partially or completely encloses the headset 14a in its hollow chamber 26 when the headset 14a is docked with the electronic device 12 or accessory of the electronic device 12. This provides protection to the headset 14a and compactly stores the headset 14a with the electronic device 12 when not in use. The headset 14a compactly stores and protects the speaker 30 and the earpiece 32 in the interior chamber 42 of the headset 14a when they are shifted to a retracted position and when the cover 40 is shifted to a closed position. The input button 36 can also be used as a home button, a power button, or any other additional input for the electronic device 12 when the headset 14a is connected to the electronic device 12 or accessory. In addition, the connectors of the headsets 14b-i retain the contact between the headsets 14b-i and the device 12 and prevent the headsets 14b-i from becoming accidentally disconnected from the electronic device 12. The integrated wireless electronic system 10 allows both devices to charge simultaneously via a single charger.
A headset 66 constructed in accordance with another embodiment of the invention is illustrated in FIGS. 13-15.
