Abstract
The present disclosure relates to a method and apparatus for manufacturing a passive component for an acoustic transducer, wherein a mixture of metal oxide filler with an epoxy resin is subjected to ultrasonic wave generated and followed by an addition of a hardener to cast the passive component for the acoustic transducer. Mixing the materials with the ultrasonic wave improves the dispersion of the metal oxide filler over conventional passive components, thus enabling the passive component to have uniform surfaces, resulting in improved sound velocity and attenuation characteristics with acoustic transducers that use the passive component manufactured by the present disclosure.
