Abstract: A loudspeaker, comprising a magnet unit which generates a magnetic field and a movable element suspended for resilient movement around a stable rest position for radiating sound with selected properties. The loudspeaker further comprises an electrical conductor connected to the movable element and having current feed terminals. The conductor is placed in the magnetic field such that when current is passed through the conductor a force is exerted on the movable element so that the movable element is displaced from its rest position. The loudspeaker includes a cooling element producing a gas flow for forced cooling of the conductor.
