The invention relates to a voice coil support () for a coil transducer motor structure () having a first surface () towards one end and a second surface () towards the other end along an axis of displacement Z, the voice coil support being adapted to receive at least one coil (H,L) wound therearound an outer surface () arranged in use for displacing the voice coil support () along its axis of displacement Z, as a current is driven through the coils (H,L) when the voice coil support () is placed in a magnetic field, characterized in that the voice coil support () comprises a material adapted to prevent airflow communication between at least the first surface () and the second surface ().

Voice coil support for a coil transducer motor structure

The disclosure relates to an electrodynamic-transducer magnetic motor device () having a moving coil comprising a magnetic circuit consisting of a tied angular magnet (), characterized in that said tied annular magnet has a hollow annular structure, said hollow annular structure comprising an annular cavity () connected to an upper portion () of an external surface () of said hollow annular structure by a first annular channel () forming a first gap in which a first winding () of the moving coil can move.

Electrodynamic-transducer magnetic motor

The present disclosure relates to a coil transducer motor structure () including at least one coil (), at least one magnetic element () arranged in use to provide a path for magnetic flux between the ends of said coil (), wherein the magnetic element () has a structure providing a curvilinear path therethrough for said magnetic flux.
