Ultra Compact Receiver

Abstract

This patent application discloses a combination Amplitute Modulation (AM) receiver and sound reproducer. A hollow sphere (or cylinder) of piezoelectric material coated with a thin conductive layer is configured such that it receives the electromagnetic energy associated with an AM signal. The thickness of the piezoelectric material is selected to resonate at the AM signal's carrier frequency.
