ABSTRACT:
The audio player is configured to be attached to a gift. In one embodiment, the audio player contains an electric circuit including a battery, a switch, an audio memory and loudspeaker in a series circuit. The switch is held open by a card positioned in a slot in the body of the audio player. The card usually contains the gift giver's and gift recipient's names and may contain a written sentiment. When the card is removed from the slot the switch is closed so that the memory produces a sequential signal. This is transformed by the loudspeaker into audible sound. The audible sound is a verbal or musical greeting, which may correspond to the occasion for which the gift is being presented. Other electrical and mechanical embodiments are disclosed.
