Abstract

PURPOSE:To reduce an edge deformation, by making equal the amount of volume to be taken off by the edge both for the oscillation of a diaphragm toward the radiating direction of acoustic waves and the reflecting direction. CONSTITUTION:An edge 11 is fitted to a frame 8. The edge 11 consists of a part 11a projected toward the radiating direction D of acoustic waves and a part 11b projected toward the reflecting direction. The width of the parts 11a, 11b is set so that the volume V3 to be taken off of the edge 11 from the position A to the position B is equal to the volume V4 to be taken off of the edge 11 from the position A to the position C. Thus, deformation due to the harmonics of an even number of order of the acoustic waves can be reduced by this arrangement.
