Abstract
A talking greeting card has a front display panel and overlapping rear panels adapted to lie substantially flat in one configuration. The front panel may be bowed in convex shape and held in such second configuration by tabs which secure the rear panels together in tension. A flexible sound record strip extends through a slot in the bowed front panel and has a surface prepared to produce sounds when a sliding element, such as the thumb nail of a user, moves along the surface. The sound is amplified by the bowed front wall and overlapping rear walls which act as a sound amplifier.
Claims1
In a greeting card assembly, the combination of:
- a front display panel having side edges, two rear panels joined to opposite side edges of said front panel, said three panels being adapted to lie substantially flat in one configuration, means for joining said rear panels together in tension and in a second configuration to cause said front panel to bow in a convex manner and thereby form a space between the joined rear panels and the bowed front panel, the front panel having a slot, a flexible sound record strip extending through the slot in close contact with said front panel and having an abutment positioned within said space, the abutment being too large to pass through said slot, said sound record strip having a prepared surface which produces audible sounds upon sliding contact with a moving element such as the thumb nail of a user, the front and rear panels serving as an acoustic amplifier for such sounds.
