Abstract: Rechargeable wireless earphone systems and charging cases are disclosed. The rechargeable charging case, which doubles as a storage case for the earphone components, includes externally accessible charging ports adapted to charge the rechargeable battery contained therein as well as for charging other electronic devices. The earphones are configured such that they may be used even when charging or when the earphone system battery is depleted. An alignment and positioning mechanism is provided to align and electrically connect charging contacts of a controller housing of the earphone system with charging contacts provided in the charging case to better secure and facilitate the charging process when the controller is received within the charging case. Reversibly detachable ear hooks and ear canal plugs are uniquely designed and configured to be independently attached to the earphone housing and compliantly adjustable to the desired shape for user comfort.

Abstract: A portable speaker unit that includes a battery-powered, portable wireless speaker and can be seamlessly incorporated and operate as a speaker element of the vehicle speaker system. The portable speaker unit includes 2.1 channel audio capability with individually sealed speaker chambers for each of the 3 speakers within a housing. The portable speaker unit can be electrically and mechanically interfaced with the vehicle speaker system through a vehicle mount. The portable speaker unit can also operate as a portable wireless speaker when removed from the vehicle interface.

Abstract: The present invention provides a portable and compact battery-powered stereo speaker assembly that incorporates a DC to DC converter, which enables power from the internal stereo speaker assembly battery to charge an interconnected hand-held device, such as a smartphone, through a USB connection, thereby extending the time that the device can be used untethered from the AC power grid. A DC to DC converter enables the charging function can be implemented even if the speaker assembly is not connected to the AC power grid, and even if the battery of the stereo speaker assembly is not fully charged. The stereo speaker assembly also incorporates Bluetooth connectivity, a proprietary open wireless technology standard, developed by Ericsson in 1994, employing frequency-hopping spread spectrum radio transmissions in the ISM band from 2400-2480 MHz.
