  • Publication number: 20120143431
    Abstract: The present invention provides a diagnostic apparatus using a microphone. More specifically, the diagnostic apparatus utilizes a first microphone, a second microphone, a first unit, a controller and second unit. The first microphone is positioned within an engine compartment and the second microphone is positioned within an interior of a vehicle to receive the noise. The second unit records the noise inputted through the first microphone or the second microphone or both and the controller analyzes and diagnoses a vehicle utilizing the noise recorded by the first unit to determine if a failure in the vehicle has occurred. When a vehicle failure is detected by the controller, the second unit then notifies a user of the location of a failed part in the vehicle.
