Abstract:
1. A ribbon microphone unit comprising: a support having a window in a longitudinal direction thereof; a pair of magnets mounted along the longitudinal sides of the window generating a magnetic field between the pair of magnets; a ribbon diaphragm configured to vibrate in a direction, the ribbon diaphragm is disposed such that the direction of vibration of the ribbon diaphragm crosses the magnetic field generated by the pair of magnets; and a circuit substrate comprising signal paths that conduct electrical signals generated by vibration of the ribbon diaphragm to output terminals, wherein the signal paths are symmetrical about a longitudinal central axis of the ribbon diaphragm, and wherein a first signal path of the signal paths is conducted to a first terminal of the ribbon diaphragm and the first signal path is a loop signal surrounding the entire periphery of the ribbon diaphragm.
