Abstract

The application relates to speaker configured to emit sound in a main sound emission direction, the speaker comprising a movable diaphragm; a drive unit comprising a magnet generating a magnetic field, a first pole piece comprising a through hole arranged to contact the magnet on a first surface of the magnet, a second pole piece arranged to contact the magnet on a second surface of the magnet opposite the first surface, wherein the first and second pole pieces are configured to generate a magnetic field in an air gap between the first and second pole piece where the diaphragm is located. The speaker includes a light source configured to emit light and a light guide configured to guide the light emitted by the light source through the through hole in direction of the main sound emission direction to the movable diaphragm, the light guide comprising an elongated first section with a longitudinal axis parallel to the main sound emission direction and a second section extending substantially perpendicular to the elongated first section, the light guide being configured to guide the light through the elongated first section to the second section where the light is guided in direction of the movable diaphragm, wherein the elongated first section comprises a first connecting element and a second connecting element to provide an interference fit between the light guide and the first pole piece.
