Abstract

PURPOSE:To improve characteristics by suppressing abnormal vibrations of a damping film by fixing the damping film part which is not operated on directly by the sound pressure of a diaphragm. CONSTITUTION:A rib 10 is projected at the center part of a coupling part 1b facing to a damping film 6 so that it extends from the body of a base 1 to a supporting part 1a. To this rib 10, the damping film 6 is fixed. Thus, the part of the damping film 6 where the sound pressure of a diaphragm 2 does not operate directly via damping meshes 5 is fixed to suppress abnormal resonance of the damping film 6, thus improving sound-pressure frequency characteristics.
