The present invention relates to the operating principle of a loudspeaker () with an induction motor (). The motor () has two magnets (and) positioned on either side of a central core (). The magnets (and) thus create two magnetic fields (and) doubling the magnetic field detected in the movable armature (). The magnetic field coupled to the electrical field generated by a fixed coil () creates a force in the armature (), which is linked to diaphragm () producing the sound. Thus, by increasing the magnetic field, and therefore the force generated in the armature (), the performances of the loudspeaker () are likewise enhanced.

A deployable frame for a weather and/or sun protection device, including: a mast with a longitudinal axis on which a slider is mounted so as to slide between a first position in which the frame is closed and a second position in which the frame is open; at least one rib connected by a stretcher to the runner, the rib including an end connected to a notch carried by one end of the mast, wherein the rib includes a first segment formed of a first part and a second part that are movable relative to each other about the extension axis of the first segment, the first part of the first segment of the rib is connected to the notch by a pivot connection about an axis which is perpendicular to a plane inclined obliquely to the longitudinal axis of the mast so that in the first closed position of the frame the first segment of the rib extends along the mast and in the second open position of the frame the first segment of the rib is moved away from the mast.

The present invention relates to principles for cooling the stationary winding of an induction motor, said winding being positioned outside the movable armature. The cooling can be achieved by means of cooling fins, openings allowing the ventilation of the winding with or without a fan, a fluid circuit outside the bowl, a fluid circuit inside the bowl, a fluid circuit inside the winding, and/or the addition of heat pipes inside the bowl. This motor as presented can be used, without limitation, inside loudspeakers or vibrators.
