Abstract
Audio or sound envelopes contain or are combined with a sound module for generating and playing prerecorded sound tracks upon the opening of the envelope or removal of its contents. Operation of the sound module may be activated by the opening of the envelope flap, or by removal of the envelope contents. The flap is configured with a removable strip which protects the sound module from damage before and after opening. The sound module can be replayed by repeated operation of the flap. Alternate embodiments of the audio envelopes have other structural or operational features which work in concert with the sound module.
