A speaker-element for a speaker includes two substantially mutually opposing spaced apart membrane planes, where each membrane plane comprises at least one electromagnetic wire arranged for creating a magnetic field upon an electric current passing through the electromagnetic wire. A permanent magnet is arranged between the two membrane planes, the electromagnet wires of the two membrane planes are connectable to an electric power source so that the electric current passes therethrough in substantially mutually opposing directions to create substantially mutually opposing magnetic fields, such that upon passing an electric current through the electromagnetic wire of each membrane plane said membrane planes are both either attracted towards or repulsed from the permanent magnet and thereby moved towards or away from each other, respectively, thereby producing a sound wave.
