ELECTROACOUSTIC CONVERTER Russian patent published in 2003 - IPC

Abstract RU 2216129 C2

FIELD: piezoelectric electroacoustic converters. SUBSTANCE: proposed electroacoustic converter includes reinforcing member, stack of piezoelements connected in parallel, sealed electric connector for connection to generator of electric oscillations, straps and sealing shell. Reinforcing member is axially symmetric sealing shell placed outside of stack of piezoelements and its ends are provided with inner threads of different directions, straps carry corresponding outer ribs. EFFECT: increased functional reliability and consequently efficiency of converter as whole. 2 dwg
