ABSTRACT:
A compact portable cellular telephone extension that provides additional electronic functions is implemented in a case attachable to a first external surface of the cellular phone to form a physically integral unit. A connector is supported by the case and couples the extension electronics to the cellular phone electronics. The connector connects through a second external surface of the cellular phone that lies in a plane different from the plane of the first external surface. A speaker arm extends from the case and supports a speaker unit. The speaker arm is positionable in a first position adjacent a third external surface of the cellular phone and in a second position away from the third external surface allowing the case to be readily attached and detached.
