Abstract
Provided is an apparatus for preventing eavesdropping using a piezoelectric film. The apparatus includes a vibrator including the piezoelectric film, conductive layers connected to top and bottom surfaces of the piezoelectric film, and electrodes connected to the conductive layers, and a noise signal generator electrically connected to the vibrator to generate and transmit an electrical noise signal to the vibrator. The vibrator generates vibration in a solid body in close contact with itself in response to the electrical noise signal.
