NettetThe R.C.A. microphone type BK-6B is a pressure-operated moving coil instrument of unusually small dimensions. NettetA moving-coil dynamic microphone converts sound to audio via electromagnetic induction. It does so with a cartridge/element with a conductive coil attached to a movable diaphragm that vibrates within a magnetic structure. The diaphragm movement causes a coinciding audio signal to be produced.
NettetA conductor coil (a copper coil wound tightly onto a metal core) is rapidly rotated between the poles of a horseshoe-type magnet. An armature is made up of a conductor coil and a core. The armature is rotated by connecting it to a shaft of a mechanical energy source, such as a motor.
