Electrodynamic position transducer

An electrodynamic position transducer comprising

• a rigid, hollow casing in which a membrane is clamped, said membrane together with a portion of the rigid, hollow casing defining at least one chamber of variable volume;
• a coil comprising at least one turn formed by a pattern of flat conductive tracks formed on a coil support made of insulating material;
• an interaction element configured to interact magnetically with the coil as a result of a movement of the membrane, in such a way that a self-inductance of said coil is variable depending on a relative position of the interaction element with respect to the coil, and
• a circuit coupled to said coil and configured to provide an output signal, a parameter of said output signal being indicative of the self-inductance of said coil;
• wherein at least one hole or recess is formed in the coil support, said hole or recess being configured to receive said interaction element in such a way that one end of the interaction element is positionable flush with said at least one turn or beyond said at least one turn.
