ELECTROACOUSTIC TRANSDUCER Russian patent published in 2017 - IPC H04R17/00 

FIELD: physics.

SUBSTANCE: transducer contains a coaxially fastened diffuser holder, a diffuser, a waveguide with a bimorph piezoelement rigidly coupled thereto, conductors to a source of electrical oscillations. The bimorph piezoelement is attached coaxially to the waveguide, which is made in the form of a thin-walled cone and is established by narrowing its body away from the periphery of the bimorph piezoelement to the top of the diffuser, the bimorph piezoelement on the opposite side of the waveguide is equipped with a convex membrane.

EFFECT: increasing sound pressure and efficiency, reliability of the transducer, simplifying the design.
