An electromagnetic machine with a deformable membrane (1) includes at
least one fixed part which can direct a magnetic flow interacting with at
least one moveable part (12) having regions which are magnetically
polarized in order to ensure that alternative displacement of the
moveable part (12) corresponds to an alternative variation of the
magnetic flow in the fixed part, the moveable part (12) being kinetically
linked to an edge (5) of the membrane (1) such that an undulation of the
membrane (1) corresponds to an alternative displacement of the moveable
part (12), wherein the fixed part and moveable part (12) are arranged in
such a way that the moveable part (12) can be displaced in a rotating
manner.
