Abstract: In some embodiments, portable speakers can be small and lightweight and can communicate with one or more audio device over wired or wireless connections. In some embodiments, portable speakers achieve reduced complexity as compared to typical high fidelity systems (e.g., by including a reduced number of speaker drivers and amplifiers), while still maintaining high fidelity stereo audio playback, thereby achieving both portability and high quality audio capability. For instance, certain implementations of the speaker include two primary speakers disposed on opposing faces of the speaker enclosure (e.g., full or mid-range drivers) and two tweeters, also disposed on opposing faces. Primary speakers can be disposed on respective ends of the housing and each can output a different stereo channel. Each tweeter can be positioned on different face of the housing. The speaker system according to some embodiments generates a mono high frequency signal to drive the tweeters.

Abstract: A multi-user videophone hub may include a processor, a video camera, a display, and a wireless communication interface to communicate with at least one local handset. The processor may be configured to receive video from the at least one local handset, and create a composite video stream based on video from the video camera and the video received from the at least one local handset. The processor may also be configured to send the composite video stream to a remote device and receive video from the remote device. The processor may then show the video from the remote device on the display, and send the video from the remote device to the at least one local handset.
