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
