Zusammenfassung: | An improved electromechanical transducer is provided. In an embodiment, the transducer comprises at least two flux modules, each defining a magnetic circuit having a gap; an armature configured to move along a longitudinal axis passing through the gaps; and a gas containment structure laterally surrounding the armature, wherein: the at least two flux modules are provided outside the gas containment structure; and the armature comprises a reinforcing portion laterally outside of the gaps that is wider in a direction parallel to the flux in the gaps than at least one of the gaps. |
