To fix, a bolt 11 is inserted in the mounting hole in a rubber bush 6 provided in the front part of the cabinet 5, and the rear part 12 of the cabinet 5 is tightly fastened with the bolt 11 on the wall surface 13f through a spacer 10 flexible and vibration-absorptive. Thereafter, the rubber bush 6 is mounted to the mounting hole in which the bolt 11 is inserted, thus a diaphragm protection net is fixed with the rubber bush 6. In such a way, the thin type speaker system can be fixed tightly on the wall surface without protruding a screw, etc., from the front part of the speaker.
