Abstract
An acoustic power transformer includes: an input port adapted to receive an input signal; a transmitting acoustic transducer coupled to the input port and adapted to transmit an acoustic wave in response to the input signal received at the input port; a receiving acoustic transducer adapted to receive the acoustic wave and in response thereto to produce an output signal; an output port adapted to output the output signal; and an acoustic medium disposed in an acoustic wave propagation path between the transmitting acoustic transducer and the receiving acoustic transducer. In one case, at least one of the transmitting acoustic transducer and receiving acoustic transducer includes a Fresnel lens. In another case, the transformer includes an acoustic lens disposed in the acoustic wave propagation path between the transmitting acoustic transducer and the receiving acoustic transducer.
