Patent ID: 7323961

Claim:
An electromagnetic machine with a deformable diaphragm ( 1 ; 41 ; 51 ), the machine comprising at least one stationary part ( 6 , 7 ; 16 , 17 ; 16 ′, 17 ′; 26 , 27 ; 56 , 57 ) suitable for channeling a magnetic flux that interacts with at least one moving part ( 10 ; 20 ; 20 ′; 30 ; 60 ) having regions that are magnetically polarized (N, S) in such a manner that alternating displacement of the moving part and alternating magnetic flux variation in the stationary part correspond, the moving part being drivingly connected to an edge ( 5 ; 45 ; 55 ) of the diaphragm such that alternating displacement of the moving part corresponds to deformation of the diaphragm, wherein the stationary part and the moving part are arranged to confer rotary type displacement to the moving part.
