  "abstract": "A stand for a mobile electronic device provides a font stand support surface and a rear stand support surface. Conveniently, the stand is configured to carry each of a mobile electronic device and a battery recharge pack. The front stand support surface and the rear stand support surface are formed in an inverted V shape orientation angled at an inclined plane and joined at an apex along a common edge between the two support surfaces. The inclined plane is angled at an angle to allow the user to view a display screen of the mobile electronic device. A passive acoustic enhancement panel is disposed along a side edge at an end of the stand. The passive acoustic enhancement panel is oriented to reflect an audio signal emitted from the mobile electronic device forwardly of the stand where the enhance acoustic signals may be heard by the user.",
  "claims": [
    "1. A stand for a mobile electronic device, comprising: a front support surface and a rear support surface oriented in an inverted V shape with the respective surfaces angled at an inclined plane and joined along a common edge along an apex of the inverted V shape, the front support surface dimensioned to support a back surface of the mobile electronic device; an acoustic enhancement panel joined along a side edge of the front support surface, the acoustic enhancement panel angled forwardly of the front support surface and oriented to reflect an audio signal emitted by a speaker of the mobile electronic device forwardly of the stand; and a charging aperture disposed through the acoustic enhancement panel, the charging aperture dimensioned to receive a charging connector of an electrical charging device.",
    "2. The stand of claim 1, further comprising: a front ledge extending along a lower end of the front support surface.",
    "3. The stand of claim 2, further comprising: a lip protruding upwardly from the front ledge.",
    "4. The stand of claim 1, further comprising: a rear ledge extending along a lower end of the rear support surface.",
    "5. The stand of claim 4, further comprising: a lip protruding upwardly from the rear ledge.",
    "6. The stand of claim 1, wherein the front support surface and the rear support surface are movably joined along the apex; and the angle of the front support surface and the rear support surface is adjustable between 5 degrees and 95 degrees.",
    "7. The stand of claim 1, wherein the acoustic enhancement panel is adjustably joined along the side edge of the front support surface.",
    "8. The stand of claim 7, wherein the acoustic enhancement panel is adjustable between 5 degrees and 95 degrees.",
    "9. The stand of claim 1, further comprising: a battery pack carried on the rear support surface.",
    "10. The stand of claim 9, further comprising: a solar cell integrated with the battery pack to charge the battery pack.",
    "11. The stand of claim 9, further comprising: a charging cable extending from the battery pack and through the charging aperture.",
    "12. The stand of claim 11, further comprising: the mobile electronic device carried on the front support surface.",
    "13. The stand of claim 12, wherein the charging cable is connected to a charging port of the mobile electronic device."

  "description_excerpt": "The present invention relates to stands for mobile electronic device, and more particularly to stands with passive acoustic enhancement for an audio signal produced by the mobile electronic device.\n\nMany mobile electronic devices, such as cellular telephones, include one or more internal speakers to allow a user of the device to listen to an audio playback on the device. The internal speakers have a limited audio output capacity.\n\nAccordingly, means have been developed to amplify or enhance the audio output of the mobile electronic device. Typically, these will be active acoustic enhancement systems, incorporating an electronic amplifier circuit and a speaker. These active systems may also include equalizers, and the like, to enhance the audio system played on the speaker. The mobile electronic device is connected to these systems via a dock having an electronic connection between the mobile electronic device and the electronic amplifier circuit. These systems may include an internal battery source for power, or may include a power adapter for connection to an electrical power source, such as a wall outlet or a vehicle electrical system.\n\nOther systems employ a passive acoustic enhancement incorporated in the stand that include various wave guide chambers to reflect the sound wave output of the internal speakers to develop a more robust audio signal from the output of the speakers. The wave guide chambers can be convoluted structures, which can increase the costs of manufacture for even a simple stand.",
