Speaker-element and speaker comprising such a speaker-element

Abstract

The invention relates to a speaker-element for a speaker, comprising two substantially mutually opposing spaced apart membrane planes, wherein each membrane plane comprises at least one electromagnetic wire arranged for creating a magnetic field upon an electric current passing through said electromagnetic wire, wherein at least one permanent magnet is arranged between the two membrane planes, wherein the electromagnet wires of the two membrane planes are connectable to an electric power source in such a manner, that the electric current passes there trough in substantially mutually opposing directions and thereby creating 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.
