PROBLEM TO BE SOLVED: To provide audio speaker structure for an automobile in which the number of part items is not increased and an inner space of an instrument panel is prevented from being pressed. SOLUTION: Ceramic speakers 13, 14 are attached to a front defroster duct (air conditioner duct) 7, and a wall surface of the front defroster duct 7 is oscillated to generate sound. The sound A is generated from a defroster opening 4 of an upper surface of the instrument panel 1, and thereafter reflected to an occupant side by a front window. Therefore, an occupant can feel spreading sound from a space in front of him or her, which is almost the same in height as his or her ears. The audio speaker structure is obtained only by attaching the ceramic speakers 13, 14, which are small parts, to the front defroster duct 7 which is the existing air conditioner duct, and therefore no remarkable increase in the number of the part items is not caused and the inner space of the instrument panel 1 is prevented from being pressed.
