An alternating current (AC) power source 302, such as an electrical socket, can be engaged with an AC-DC converter 306 in the charging case 208 via a cord 304. The output of the converter 308 can be used to charge one or more batteries 310 in the charging case in the illustrated exemplary non-limiting architecture. A direct current (DC) power source 312 can also be engaged with the charging case 208 to charge the battery 310, if desired. In the illustrated exemplary architecture, the charging contacts 206 are electrically connected to the battery 310 and provide DC power through the earbud contacts 204 to charge one or more batteries 314 in the earbuds 200 when the earbuds are placed in the receptacle 210 of the charging case 208. It should be understood that the charging case battery 310 may be omitted and the charging case contacts 206 may be directly connected to the DC source 312 and / or the AC-DC converter 308.

[0036] One or more batteries 314 of the earphones 200 power one or more processors 316 that access one or more disk-based or solid-state computer storage 318 within the earphones to play audio on one or more speakers 320 within the earphones 200. Audio may be received via wireless signals from an audio source, such as a mobile device 300, which may be configured as a wireless telephone, through one or more wireless interfaces 322, such as one or more transceivers, such as a Bluetooth transceiver and / or a Wi-Fi transceiver. The earphones 200 may also include one or more sensors 324 for purposes that will be disclosed shortly.

[0037] The mobile device 300 may include one or more wireless interfaces 326, such as one or more transceivers, such as a Bluetooth transceiver and / or a Wi-Fi transceiver, for communicating with the earphones 200. The mobile device 300 may also include one or more processors 328 that access one or more disk-based or solid-state computer storage 330, which may contain audio tracks. The mobile device 300 may include one or more displays 332, one or more cameras 334, and one or more audible and / or visual and / or tactile alarms 336 controlled by the processor 328.

[0038] In the illustrated example, in addition to the charging components described above, the charging case 208 may include one or more wireless interfaces 338, such as Bluetooth and / or Wi-Fi transceivers controlled by one or more processors 340 that access one or more disk-based or solid-state computer storage 342. The processor 340 may also communicate with one or more sensors 344, one or more audible and / or visual and / or tactile alarms 346, one or more microphones 348, and one or more imaging devices 350, such as a still or video camera. The charging case 208 may further carry human-operable phone and computer selectors 352, 354 for increasing and decreasing the mix of audio played by the earphones 200 from the mobile device 300 and from a laptop or laptop / PC 356, respectively, which may communicate with any or all of the components shown in FIG. 3. It should be noted that while FIG. 3 shows hardware-implemented phone and computer selectors 352, 354, the selectors may also be implemented in software, for example using a touch-sensitive display. Additionally, one or more selectors may be provided on the case for gain control of the audio playback.

[0039] 4 illustrates that the charging case 208 may be advantageously employed not only to charge the earphones 200, but also to charge an audio device when connected to, for example, a laptop or PC 356 or other audio source. Note that the charging case 208 may be plugged into and receive audio from a Universal Serial Bus (USB) connector on the phone 300. Additionally, note that the logic of FIG. 4 may be executed by any processor herein, including the charging case processor 346, either alone or in cooperation with other processors described herein.

[0040] Beginning at block 400, the charging case 208 may be connected via a wired or wireless path to an audio source, such as a laptop / PC 356 and / or phone 300. Block 402 indicates that Bluetooth® pairing or other near field communication pairing may be established between the earbuds 200 and the wireless charging case 208.

[0041] Proceeding to block 404, the charging case 208 can receive audio signals from a source, such as the laptop 356, as well as from the phone 300. Note that the earphone microphone signal can be sent to the laptop / PC 356 and / or the phone 300 to play the signal from the earphone microphone on the laptop / PC speaker and / or the phone speaker.

[0042] Moving to block 406, the charging case 208 can transmit audio signals to the earphones 200 via Bluetooth® or other communications link, allowing the earphones to hear audio from the laptop 356 without having to pair the earphones with the laptop via Bluetooth® and without disrupting the existing Bluetooth® connection. In one embodiment, the charging case processor 340 can act as a master in transmitting audio signals to the earphones. Alternatively, the charging case 208 and earphones 200 may all be connected to the phone 300 or charging case 208, and one of the earphones 200 may connect to the phone 300 and act as a master to feed audio to the other components for mixing.

[0043] Block 408 indicates that audio from, for example, the laptop 356 over Wi-Fi or other sources may be merged with the audio received from the mobile device 300, as desired. This mix may be performed, for example, by the earphone processor 328 or by the charging case processor 340. Moving to block 410, as the user manipulates the phone and computer selectors 352, 354 on the charging case 208 to increase and decrease the mix of audio played by the earphones 200 from the mobile device 300 and from the laptop or laptop / PC 356, respectively, the mix changes accordingly, in block 412. In block 414, audio is played on the earphones.

[0044] 5 and 6 are example screenshots of an example user interface that may be presented on any display 500 disclosed herein consistent with the present principles.

[0045] 5 shows three selectors: one for selecting to play audio on the earphones sourced from the phone (at 502), one for selecting to play audio from the laptop 356 (at 504), and a third selector 506 for selecting to play a mix of audio from the phone and laptop. When the charging case 208 is the master, the selection is sent to the charging case, which provides the selected audio to the earphones either directly from the charging case 208 to the earphones, or from the phone or laptop, which accesses the associated file and is controlled by the charging case processor 346.

[0046] Assuming the user selected a mix in FIG. 5, FIG. 6 so informs the user at 600 and advises the user at 602 to change the mix as desired by manipulating the phone and computer selectors 352, 354 on the charging case 208 to increase and decrease the mix of audio played by the earphones 200 from the mobile device 300 and from the laptop or laptop / PC 356, respectively.

[0047] Although particular embodiments have been shown and described in detail herein, it should be understood that the subject matter encompassed by the present invention is limited only by the scope of the claims.
