<p>The invention relates to an electromechanical actuator 100 for hearing applications comprising one or more permanent magnets 10 and one or more magnetically permeable members 20 arranged to form a stator 50 and armature 70 arranged to provide one or more magnetic flux circuits 80, 80' configured to give rise, in the armature seat 52, to a position of unstable equilibrium for the armature 70 along the longitudinal A-A' axis and regions either side of the position of unstable equilibrium along the longitudinal A-A' axis where the armature applies a destabilization-driven force to the compliant member that decreases the effective rigidity of the compliant member that retains to armature in a neutral position. The invention also relates to a hearing aid system incorporating the electromagnetic actuator.</p> |
