Abstract
Electromagnetic coil for loudspeakers, which are those formed by the joint coupling of a central electromagnet and two lateral cores, of which one of them has an axial appendix that is through through the other two pieces and which jointly defines with them an annular recess for coupling the speaker, essentially characterized in that each of the two said cores has an orthogonal step at its end edge provided for fitting a bushing that embraces and immobilizes the set of the three pieces and that will preferably be of plastic material and will be applied by thermoinjection.
