ULTRASONIC TRANSDUCER HAVING SOUND ABSORBING LAYER FOR IMPROVING HEAT DISSIPATION

摘要

Disclosed is an ultrasonic transducer having a sound absorbing layer for improving heat dissipation. The ultrasonic transducer, according to one embodiment of the present invention, comprises: an active element; a matching layer formed on the front surface of the active element for matching the acoustic impedance of an ultrasonic wave propagated to the front surface of the active element; and a sound absorbing layer formed on the back surface of the active element for blocking or damping an ultrasonic wave propagated to the back surface of the active element, wherein the sound absorbing layer comprises a thermal conductor having a bracket structure with respect to an elevation direction.
