Circuits, systems and methods of hybrid electromagnetic and piezoelectric communicators

摘要

Circuits, systems and methods that utilize two transducers, of which at least one is a piezoelectric transducer, adapted and coupled to receive and/or generate signals in the forms of sound waves, mechanical vibrations, and/or electromagnetic energy. In one version, two transducers each receive and/or generate separate vibrational energy signals that bear information. Two or more transducers coupled to a switching circuit may send or receive piezo-electrical circuit output signals that include a carrier wave having different frequencies that are within separate frequency ranges. Two or more transducers may generate output signals that are simultaneously processed by or multiplexed by a switching circuit.

1. A communicator circuit, the communicator circuit adapted for coupling with a first piezoelectric transducer, a second transducer, and an output target circuit, the communicator circuit comprising:
a first signal front end communicatively coupled with the first piezoelectric transducer; a second signal front end communicatively coupled with the second transducer; a switching circuit communicatively coupled with the first signal front end, the second signal front end, and a processing circuit; and the processing circuit communicatively coupled with the output target circuit, wherein the switching circuit is adapted to enable a transmission of a switching circuit output signal to the processing circuit, and the processor circuit is enabled to receive the switching circuit output signal and therefrom modify, derive, generate and transmit a resultant output signal that is a selectively an electromagnetic signal or a pressure wave signal.
