We are Stanford college students designing toys for children with autism, and we need help optimizing our audio circuit design!

We are designing a puppet that has multiple attachable faces. When attaching each face, the circuit completes and plays a different sound.

*How does the circuit work?*

Currently we have the battery in the main body, and a sound board and speaker in each face. The faces attach to the body by conductive magnets completing the circuit and playing the file in the sound board.

*What we need help with?*

We would like to consolidate the circuit into something like a "greeting card circuitry": inexpensive, efficient, and more compact.

We are currently using these components in the circuit.
