A wireless infrared peripheral interface for a communication device having a cellular radio transceiver includes a peripheral interface. The peripheral interface includes at least one infrared signal source and at least one infrared detector. The signal source and detector are coupled with dispersing optics. An interface circuit is coupled to the infrared signal source and detector. A processor is coupled to the interface circuit, wherein the processor controls the interface circuit to process data signals that are conveyed through the infrared source and detector so as to communicate with a peripheral device that is proximate to the communication device. The dispersing optics reduces the dependency of optical alignment between the infrared data ports of the peripheral device and communication device.

Wireless infrared peripheral interface for a communication device

A portable communication device includes a speaker enclosure having a speaker and a plurality of telescoping nested shells moveable between a collapsed configuration and an expanded configuration. The shells have a top and bottom surface and interlocking sidewalls such that when the enclosure is deployed into an expanded configuration the shells form a rigid enclosure with a substantially sealed acoustic space therein. The space tunes an acoustic compliance for the speaker so as to improve broadband frequency response whether the communication device is using a privacy or speakerphone mode of operation.
