An air cooled ultrasonic apparatus comprises a housing having an air inlet, an air outlet, a first periphery, and a second periphery. A plurality of first and second protrusions radially extend from the first and second peripheries. The housing houses a piezoelectric transducer means and an elongated horn which is operably supported by the first and second protrusions, so that a cooling air is supplied through the air inlet into the housing and discharged through the air outlet, thereby significantly enhancing effectiveness and efficiency for its application to medical, dental and plastic surgery as well as industrial use.
