Abstract
A system that detects vibrations from a mechanical component, such as a disk drive. The system includes an excitation rod, a membrane, and a microphone. During operation, the mechanical component is coupled to the excitation rod which is coupled to the membrane, so that vibrations from the mechanical component are mechanically coupled through the excitation rod to the membrane. The membrane then converts the mechanical vibrations into acoustic waves that are transmitted through a medium. The microphone detects the acoustic waves in the medium and converts the acoustic waves into signals.
