Abstract
Abstract An electromechanical transducer including a coil supporting assembly and an armature supporting assembly detachably connected together. The coil supporting assembly includes a cylindrical casing with an internal shoulder, and a coil winding support member is clamped against the shoulder by an adjustable cap. The armature is mounted on a rod supported on a pair of diaphragm springs for relatively free axial movement but is restrained against radial and rotative movement.
