An electro-acoustic transducer in which a diaphragm has a stiffened portion which at the one hand is pivotally connected to a fixed frame portion, and at a location offset from the center of the diaphragm is connected to a U-form armature of an electromagnetic unit at the other, whereby the average amplitude of the movement of said diaphragm caused by a movement of the free end of said armature is greater than the amplitude of the latter movement.
