Abstract: A battery powered, portable multi-channel audio mixing console is disclosed. The mixing console is configured to be easily held in a user's hand like a remote control. The console is configured to wirelessly receive, via separate channels, two or more independent stereo input audio signals from separate audio sources such as cellular phones, iPads, iPods, or other computing or media player devices, independently equalize the frequencies of those input signals, independently adjust the volume of those input signals, and then mix those audio signals into a combined output signal. The console further includes user controls that can vary the relative magnitude of the first and second input signals in the combined output signal. The console is further adapted to transmit the combined output signal to one or more speakers via independent channels.

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 wireless audio speaker system that includes a speaker main unit and multiple functions provided by exchangeable accessories is disclosed. The speaker main unit includes a top sleeve and a bottom sleeve that covers the external surface of a more internal enclosure that houses the main unit electronics and circuitry. External electrical and mechanical connectors are configured to be positioned on speaker unit and are adapted to being connected to the accessories. One external connector is positioned on the top sleeve for passing power and audio signals between the speaker main unit and an accessory component that is mounted to the top sleeve. A second connector is configured to be positioned on the bottom sleeve for passing audio signals between the speaker main unit and a second speaker that is stacked to the bottom sleeve via stacking plate. Multiple exchangeable accessory components are described to seamlessly supplement functionality and enhance user experience.

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.
