Summary:A speaker device capable of emitting a sound to a user located in front of the speaker device with good sound quality and increased flexibility of design is provided. The speaker device includes: a speaker unit oriented upward; a head piece provided on an upper side of the speaker unit; and a light emitting element provided between the speaker unit and the head piece at a position where the light emitting element does not interfere with propagation of the sound. The head piece includes a reflector configured to reflect the sound emitted by the speaker unit, in a horizontal direction. The light emitting element is oriented toward the reflector. The reflector may be a surface having a shape obtained by joining two triangles each connecting between a lower end corner of a back board and an upper edge of a sound emission opening.
