Abstract

Piezoelektrisk transduktor (1) for elektro-akustisk bruk og utført spesielt med tanke på å redusere uheldig påvirkning av de metallterminaler (8, 9) som er ført fra utsiden av transduktorens hus (3) og inn til dens svingeelementer (2, 4, 5), når reduksjon av transduktorens størrelse er hensikten.De aktive elementer består av en piezoelektrisk membran (2 ) med en keramisk skive (5) og en pålagt metallplate (4), det hele oppspent inne i huset (3). Den ene av metallterminalene (8, 9) bør ha en elastisitetsmodul (X) som er mindre eller lik 100 (N/m), idet. X = bhE/4L.Her er E(N/m) Youngs modul for en metall-terminal (8, 9) i kontakt med et piezoelektrisk element, og b^ h og L (mm) er henholdsvis bredden, høyden og lengden av et rett parti (8b) av metallterminalen ( 8 ).
