摘要

This loudspeaker includes a light emitting element, a frame, a magnetic circuit including a magnetic gap, a diaphragm, a voice coil bobbin, and a voice coil. The diaphragm has: an inner circumferential end section including an end surface facing the light emitting element; and a light guide section, which has a reflection surface formed therein, and which is provided at a position where light is inputted from the end surface. A first end of the voice coil bobbin is coupled to the inner circumferential end section of the diaphragm, and a second end of the voice coil bobbin is inserted into the magnetic gap. The second end of the voice coil bobbin has the voice coil wound thereon. Light having been emitted from the light emitting element is inputted from the end surface of the diaphragm, diffused by means of the light guide section, and reflected by means of the reflection surface.
