APPARATUS AND METHOD FOR GENERATING BROAD BANDWIDTH ACOUSTIC ENERGY

摘要

An acoustic transmitter includes: an acoustic diaphragm configured to transmit acoustic waves into a medium; a piezoelectric actuator assembly configured to deform in an axial direction in response to an applied electrical signal; and a highly incompressible elastic material disposed between the piezoelectric actuator and the acoustic diaphragm and configured to transmit pressure waves to the acoustic diaphragm in response to motion of the piezoelectric actuator.
