METHOD OF MAKING AN ACOUSTIC TRANSDUCER

摘要

A method of making an acoustic transducer includes the steps of: a) assembling a previously polarized piezoelectric crystal with a pair of solid circular metal plates positioned to sandwich the piezoelectric ceramic crystal between them, wherein an epoxy adhesive is interposed between the metal plates and the piezoelectric ceramic crystal to form an acoustic transducer assembly; b) curing the acoustic transducer assembly at temperatures less than 150 degrees centigrade; c) encapsulating the acoustic transducer assembly in a flexible case with a polyurethane potting sealant to form a potted assembly; and d) curing the potted assembly at temperatures less than 150 degrees centigrade to form a hydrophone.
