Piezoelectric/electrostrictive device

摘要

A piezoelectric/electrostrictive device including a substrate and a connection plate having a first end joined to the substrate and an opposed second end extending along a first direction, and first and second opposed sides along a second direction perpendicular to the first direction. A fixing plate is joined to the second end of the connection plate. A first side of a first diaphragm is joined to the first side of the connection plate and an opposed second side of the first diaphragm is joined to the substrate. A first side of a second diaphragm is joined to the substrate and an opposed second side of the second diaphragm is joined to the second side of the connection plate. A piezoelectric/electrostrictive element is provided on at least a portion of at least one planar surface of at least one of the diaphragms.
