Abstract
An electroacoustic transducer includes an armature that is mounted for deflection between magnets where an elongated portion of the armature includes a protrusion on opposite sides thereof for limiting the deflection of the armature. The protrusions are arranged transversely with respect to the elongated portion of the armature. Among other advantages, deflection of the armature is limited to provide improved shock performance. In one example, the protrusions are located within a magnet zone of the electroacoustic transducer.
