ASSEMBLY OF AN ARMATURE AND MAGNETIC ELEMENTS FOR AN ELECTROACOUSTIC TRANSDUCER

摘要

Electroacoustic transducer comprising a case accommodating an armature (16) with at least two armature legs, a coil (19) with an air gap, which is fitted around one armature leg, a magnet/pole piece assembly (17, 18) with an air gap, which is also fitted around the one armature leg, with the air gap of the coil (19) and that of the magnet/pole piece assembly (17, 18) being located in line with each other, a diaphragm (4) and a connecting element which couples a free end of the one armature leg to the diaphragm (4). According to the invention, there are provided two identical pole piece/magnet assemblies (18, 18'), which are both arranged opposite each other on opposite sides of one leg of the armature by attaching each assembly (18, 18') to at least one other leg of the armature. Such assemblies are simple to produce and ensure proper symmetry of the assemblies with respect to the armature leg.
