An electromechanical microsystem comprising: - at least two electromechanical transducers (11a and 11b) each comprising a part (111a, 111b) moving between an equilibrium position, off-load, and an out-of-equilibrium position, under load, - at least one deformable diaphragm, - a deformable cavity, bounded by walls (131, 132, 133), at least part of the deformable diaphragm forming at least part of a first wall selected amongst said walls (131, 132, 133) of the cavity, the cavity hermetically containing a deformable medium maintaining a substantially constant volume under the action of a change in external pressure exerted on the deformable medium through one of the walls (131, 132, 133) of the cavity, wherein the moving part (111a, 111b) of each electromechanical transducer (11a, 11b) is configured such that its movement depends on said change in external pressure, or conversely such that its movement causes a change in external pressure, and wherein said at least one part of the deformable diaphragm is provided with at least one area free to deform, depending on said change in external pressure, the electromechanical microsystem being further such that: the free area being configured to cooperate with at least one external member so that its deformation causes, or is caused by, a movement of the external member, the free area of the deformable diaphragm is configured to cooperate with the external member via a pin attached to said free area, preferably in contact with said free area, the moving part of at least a first electromechanical transducer is configured so that acting upon it or an increase in external pressure causes its movement towards the outside of the cavity, and the moving part of at least a second electromechanical transducer is configured so that acting upon it or a decrease in external pressure causes its movement towards the inside of the cavity, and wherein said at least two electromechanical transducers (11a and 11b) extend on the same wall chosen from the walls (131, 132, 133) of the cavity and at a distance from the free area of the deformable diaphragm. -
