ABSTRACT:
A musical toy includes a plurality of tone producing, whistle-like structures arranged in pairs, each tone producing structure connected by a passageway to an hermetically sealed deformable hollow cavity or bulb. Each bulb includes a top generally flat surface having fixed surface area and a resilient, porous biasing agent which inflates the cavities to a predetermined size and configuration. When a cavity is depressed to a deflated position, compressed air is forced through connecting tubes into a sound generating structure thereby producing an audible, musical sound. Eight of the sound generating structures are provided in one apparatus to produce a unit having a full octave of notes. The sealed cavities are provided by selectively laminating a predetermined pattern of seal lines between two sheets of thermoplastic material such as soft, pliable vinyl sheets.
