ABSTRACT:
A generally pyramid shaped sound module is provided that is attachable to a balloon for producing hi-fidelity sound effects. The sound module includes a piezoelectric element connected at the top of the pyramid shaped piezo amplification device. An electric circuit is connected to the piezoelectric element by wires. The electric circuit includes a power supply, such as one or more batteries, and the circuitry necessary for producing or reproducing a desired sound (e.g. musical notes, voices, sounds, prerecorded sound, a combination of the aforementioned, etc.). The pyramid shape allows the piezoelectric element to be coupled to the balloon without physically touching the balloon surface. Thus, even when the balloon begins to deflate, the sound quality of the sound module can be maintained.
