Zusammenfassung:	A loudspeaker includes a light-emitting element, a frame, a magnetic circuit provided with a magnetic gap, a diaphragm, a voice coil bobbin, and a voice coil. The diaphragm has an inner circumferential end including an end face facing the light-emitting element, and a light guide having a reflecting surface formed thereon and provided at a position where light enters from the end face. The first end of the voice coil bobbin is joined to the inner circumferential end of the diaphragm, and the second end is inserted into the magnetic gap. The voice coil is wound around the second end of the voice coil bobbin. Light from the light-emitting element enters the end face of the diaphragm, is diffused by the light guide, and is reflected on the reflecting surface.
