Abstract

See full text

A novel phantom-powered FET (field effect transistor) circuit for audio application is disclosed. In one embodiment of the invention, a novel phantom-powered FET preamplifier gain circuit can minimize undesirable sound distortions and reduce the cost of producing a conventional preamplifier gain circuit. Moreover, in one embodiment of the invention, one or more novel rounded-edge magnets may be placed close to a ribbon of a ribbon microphone, wherein the one or more novel rounded-edge magnets reduce or minimize reflected sound wave interferences with the vibration of the ribbon during an operation of the ribbon microphone. Furthermore, in one embodiment of the invention, a novel backwave chamber operatively connected to a backside of the ribbon can minimize acoustic pressure, anomalies in frequency responses, and undesirable phase cancellation and doubling effects.
