  • Patent number: 12356137
    Abstract: 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.

  • Publication number: 20090279730
    Abstract: A ribbon microphone housing incorporates a shock-absorbing apparatus to reduce vibration to a ribbon for noise reduction and high-fidelity electric output signal generation. The ribbon for the ribbon microphone housing is typically made of a thin corrugated strip of aluminum. The shock-absorbing apparatus utilizes spring elements to suspend a ribbon microphone frame in air. The spring elements isolate the ribbon contained in a ribbon frame from vibration, rumble, and shock exerted to the ribbon microphone housing which encloses both the ribbon and the ribbon frame. The shock-absorbing apparatus also uses an electrically-conductive spring element configured to carry the electric output signal from an electrode connected to one end of the ribbon to one or more transformers for further signal processing.
