Disclosed is an armature apparatus having an improved structure for use in a moving iron microphone/transducer, which armature apparatus comprises a vibration transducing part (A1) located at the centre of an armature, magnetically conducting parts (A2) in two side limbs, and a connecting part (A3) at the end thereof, characterized in that the vibration transducing part has a planar structure, and by means of the connecting part which also has a planar structure, is connected to the magnetically conducting parts in the two side limbs which are orthogonal thereto, forming the armature apparatus. The advantages of the present invention at least lie in the fact that: compared with conventional armature apparatuses, the mechanical structure of the vibration transducing part in the centre of the armature and the magnetically conducting parts is improved, significantly increasing the resistance of the armature apparatus to mechanical shock; compared with conventional designs, the manufacturability of the design of the armature apparatus in the present invention is higher and costs are lower; and, moreover, the armature apparatus can also satisfy the need for different frequency responses of various microphones/transducers by means of modifying the mechanical shape of the connecting part while not altering the vibration transducing and magnetically conducting parts, thus giving a wide field of application.
