The relay portion comprises a clamping section and a wall section, and is configured so that a flexible wire does not make contact with a diaphragm or a damper during operation of the speaker. The assembly operation for placing and fixing the flexible wire becomes quite easy, and the number of components can be reduced among the speakers in accordance with the present invention.
