Circuit Diagram

A vibration switch is connected between the audio board's pin 7 and ground and orientation does not matter.

A 10uF capactitor also connects pin 7 to ground, but be sure to put it in the right way: the shorter leg goes to ground (and is also marked with - signs) and the longer leg goes to pin 7.

Connect a speaker to one or both of the outputs on the audio board.

Optionally connect a button or switch between Rst and Gnd on the audio board (helps with troubleshooting the vibration switch).
