Light guide mounting for audio speaker illumination

An audio speaker configured to emit sound in a main sound emission direction, comprising:

• a voice coil;
• a magnet assembly positioned within the voice coil, the magnet assembly comprising:
• a magnet arrangement including a through hole, and
• a light guide, wherein the light guide is configured to guide light through the through hole of the magnet arrangement, wherein the light guide includes:
• a first portion having a cylindrical shape with a longitudinal axis, wherein the first portion has a light receiving end surface for receiving light from a light source, wherein the first portion is configured to be inserted in a direction of the longitudinal axis into the through hole of the magnet arrangement,
• a second portion for emitting the light received at the light receiving end surface, wherein the second portion is arranged at an end of the first portion opposite to the light receiving end surface,
• a first protrusion protruding perpendicular to the longitudinal axis from a lateral surface of the first portion, wherein the first protrusion provides a support structure for an edge of the through hole when the light guide is located in the through hole, and
• at least one second protrusion protruding perpendicular to the longitudinal axis from the lateral surface of the first portion, wherein the at least one second protrusion is arranged in a direction of the longitudinal axis between the first protrusion and the light receiving end surface, wherein the at least one second protrusion is dimensioned to provide an interference fit of the first portion within the through hole of the magnet arrangement;
• a movable diaphragm connected to the voice coil;
• and
• the light source configured to emit light, the light source being located at the light receiving end surface of the magnet assembly, wherein the second portion of the light guide extends in the main sound emission direction through the movable diaphragm.
