Title:
ELECTROACOUSTIC TRANSDUCER FOR THE PARAMETRIC GENERATION OF ULTRASOUND
Document Type and Number:
WIPO Patent Application WO/2019/132727
Kind Code:
A3
Abstract:
An electroacoustic transducer for the parametric generation of ultrasound comprises two electrical oscillation generators, the outputs of which are connected via a linear adder, a pulse modulator controlled by a pulse generator, a power amplifier and a band-stop filter to an input of a first piezoelectric transducer having a transmitting aperture that is a portion of a convex spherical surface, wherein the electroacoustic transducer further comprises: a second piezoelectric transducer having a concave spherical aperture surface, said second piezoelectric transducer being connected to the output of the band-stop filter; and a cylindrical support structure which unites the first and second piezoelectric transducers.
