Claim:
A balloon for producing polyphonic sounds, comprising: a balloon having inside and outside surfaces and an enclosed gas expandable interior, where said inside surface encompasses said enclosed expandable interior; an inlet for the controlled entry of a gas into said enclosed expandable interior of said balloon so as to expand said interior of said balloon; a piezoelectric buzzer adhered to said balloon for producing polyphonic sounds; said piezoelectric buzzer adhered to one of said inside or outside surface of said balloon in a fashion so that upon receiving audio signals generated by a voice/sound chip, said signals are converted into said polyphonic sounds that resonate within said balloon, wherein said balloon serves as a sound amplifier, and wherein said piezoelectric buzzer is configured to operate while at least a portion of one of said inside or outside surface to which it is attached is continuously tensioned and does not lose its rigidity even if the balloon deflates; a sound module electrically connected to said piezoelectric buzzer and secured to said balloon; said sound module including a circuit with said voice/sound chip; said voice/sound chip adapted to generate the audio signals; and at least one battery arranged to power the sound module.
