Abstract

See full text

An acoustic galvanic isolation device includes a substrate capable of transmitting an acoustic wave. A first network of vibrating membrane electroacoustic transducers is arranged on a first surface of the substrate. A second network of vibrating membrane electroacoustic transducers is arranged on a second opposite surface of the substrate. An effective thickness of the substrate exhibits a gradient between the first and second surfaces with respect to propagating the acoustic wave.
