Maintaining wireless earbuds can be inconvenient to a user because they require regular electrical charge.
  • a case for a mobile electronic device includes a housing, a set of protectors extending around sides of the housing, and a base portion having a jack configured to receive a power cord input.
  • the case includes two or more earbud receiving apertures. Each earbud receiving aperture is configured to receive an earbud and has one or more electrical contacts configured to engage a rechargeable battery of the earbud when the earbud is positioned within the aperture.
  • a first electrical connector engages the jack with a power input port of a mobile electronic device when placed in the housing.
  • a second electrical connector engages the jack with the one or more electrical contacts.
  • the housing includes a panel that substantially covers a rear face of the mobile device when the mobile electronic device is placed in the housing.
  • the housing includes a bumper, a front aperture for a display face of the mobile device, and a rear aperture for a rear face of the mobile device.
  • the case may include a first magnet positioned to magnetically retain a first earbud in a first one of the earbud retaining apertures, and a second magnet positioned to magnetically retain a second earbud in a second one of the earbud retaining apertures.
  • each earbud receiving aperture may include a magnetic ring positioned to engage and secure the earbud when the earbud is positioned within the aperture.
  • the one or more electrical contacts in each earbud receiving aperture may include a magnet that secures the earbud to the aperture when the earbud is positioned within the aperture.
  • the earbuds may have speakers with magnetic components that engage with magnets or metallic components in the apertures.
  • the case may also be provided with a charging device, such as a charging cable that is configured to connect to the jack and to plug into a power source.
  • the charging device also may include a data cable that is configured to connect to the jack and to plug into a computing device and convey charge and data to the case from the computing device.
  • the case may be provided as part of a kit with two or more earbuds.
  • FIG. 1A is an example of a mobile device positioned within a case.
  • FIG. IB is an example of a mobile device case with an earbud dock and the mobile device removed from the case.
  • FIG. 1C shows the mobile device from FIG. 1A being inserted into the mobile device case from FIG. IB.
  • FIG. 2A is a front view of the case shown in FIG. IB.
  • FIG. 2B is a rear view of the case shown in FIG. IB.
  • FIG. 3A is a rear view of the case from FIG. IB with earbuds shown in FIG. 3D entering the case.

  • FIG. 7 illustrates an alternate embodiment of a mobile device case / earbud charger.
  • mobile device and “mobile electronic device” refer to a portable computing device that includes an image capturing device, a processor and tangible, computer-readable memory.
  • the memory may contain programming instructions in the form of a software application that, when executed by the processor, causes the device to perform one or image acquisition and processing operations according to the programming instructions.
  • suitable devices include portable electronic devices such as smartphones, personal digital assistants, cameras, tablet devices, electronic readers, personal computers, media players, satellite navigation devices and the like.
  • earbud refers to a device designed to fit within the ear of a human, and which emits audio signals that the earbud receives from a mobile electronic device. Examples of earbuds include in-ear headphones, hearing aids and the like.
  • the embodiments described in this document may help eliminate the inconvenience of additional charging devices, independent storage systems, wires, and tethered earbuds by: (1) using a mobile device case to provide electrical charge to wireless earbuds (regular mobi le device charging is already required), eliminating the need for an additional chargmg device; (2) embedding a magnetic dock within a mobile device case to ensure secure storage and sealed transport of the earbuds without the need for an external dock, mitigating the risk of lost earbuds; and (3) allowing for untethered earbud storage, reducing pull and tangling commonly associated with earbuds connected to a mobile device with a wire and tethered wireless earbuds.
