ABSTRACT:
A system and method is described for augmenting cellular telephone signals for a cellular telephone. In an exemplary embodiment, a cellular battery is equipped with a sound generating device that stores one or more audio signals that are activated upon receipt of a telephone call. Optionally, the battery may store a library of audio signals that may be programmable and edited. The system and method of the present invention enables a user to choose audio alert sounds beyond the scope of those provided by the manufacturer of a cellular telephone. A removable memory device containing at least one accessible sound file is attachable to the battery or telephone body, and provides increased selection of audio signal choices.
