Abstract
The invention relates to a moving part for an electro-dynamic transducer, including at least one mandrel supporting a winding of at least one coiled wire. The mandrel includes at least one first element rigidly connected inside at least one second element for guiding the moving part inside the transducer. The first element has a winding support for the coiled wire so that the coil is located inside the mandrel, as well as vibration transmitter, such as a diaphragm, the vibration being generated by the movement of the coil induced by the flow of current in the coil wire. The invention also relates to an electro-dynamic transducer including such a moving part.
