METHOD AND APPARATUS FOR MANUFACTURING A PASSIVE COMPONENT FOR AN ACOUSTIC TRANSDUCER

Document Type and Number:

WIPO Patent Application WO/2011/049319

Kind Code:

A2

Abstract:

The present invention relates to a method and apparatus for manufacturing a passive component for an acoustic transducer, in which ultrasonic waves are generated when a metal oxide filler is mixed with an epoxy resin, a hardener is added to the mixture, and the mixture is cast to be formed into a passive component for an acoustic transducer. According to the present invention, as materials are mixed using ultrasonic waves, the dispersion of the metal oxide filler is improved as compared to conventional passive components, thus enabling the passive component to have a uniform surface. The acoustic transducer which uses the thus-manufactured passive component has improved sound velocity and attenuation characteristics.
