Circuit consists of 2 push buttons (on opposite sides), a big speaker (with white cover on top), and cables that feed power from the batteries to the chip that controls the voice and speaker.
Front of mainboard with push button #1:
Red cable=power. Black cables=ground. White cables=push button 2. Yellow cables=speakers. Current entering through power cable goes through both capacitors, then enters the chip (inside the black bubble). When buttons are pressed, the chip sends a signal to the speaker.< br />
