To provide a piezoelectric type acoustic vibration generating device which is connected to many kinds of acoustic electronic equipment and used in common along with other audio equipment.

Disclosed is the acoustic vibration generating device in which an electric circuit and a piezoelectric vibrator 11 formed on a substrate 12 are molded in one body; and the piezoelectric vibrator 11 is made of a piezoelectric bimorph having a shim and is arranged at a cut part formed on the substrate 12 to be joined with the substrate 12 across the shim. Further, the electric circuit formed on the substrate 12 includes an amplifying circuit, a D/A converting circuit converting a digital audio signal into an analog audio signal, or a coil 16 which radiates a magnetic field modulated with an audio signal.
