Abstract: A multi-speaker audio system is configured to provide flexible use of speakers in any number of different environments. The multi-speaker system may include a stationary speaker unit and a portable speaker unit. The portable speaker unit may be operated in conjunction with, or separate from, the stationary speaker unit. When connected or otherwise used with the stationary speaker unit, the portable speaker unit may receive audio signals and pass at least some of the signals and/or corresponding data to the stationary speaker unit for output. When disconnected from the stationary speaker unit, the portable speaker unit may receive audio signals and output sound accordingly. The stationary speaker unit may also be able to receive audio signals and pass at least some of the signals or corresponding audio data to the portable speaker unit or output the data itself.

Abstract: A case for a portable electronic device, such as a mobile telephone (e.g., a smart phone, etc.), a portable media player or a tablet computer, includes at least one game control element for use in playing a game on the portable electronic device. In addition to the game control element, the protective case may include a receptacle and a base, which may be part of the receptacle or operatively associated with the receptacle. The receptacle is configured to receive or otherwise carry the portable electronic device, and may be configured to protect the portable electronic device. The receptacle may be configured to move relative to the base in a manner that enables a user to select an orientation of a display of the portable electronic device relative to the at least one game control element.
