する横ずれの力に対してねぢれを生じ易い欠点がある。FIG. 1 shows the basic structure of a conventional boo/speaker. In the same figure, 1 is a diaphragm, 2 is a roll edge,
3 is a frame, 4 is a gasket that fixes the roll edge 2 to the frame 3, 5 voice coils, 6 is a voice coil bobbin, and 7 is a damper that supports the voice coil bobby 76 on the 7 frame 5. In such a support system, when the diaphragm 1 is displaced ten times from the position A to the position A1, the point B on the roll edge moves to Pl. When the diaphragm again undergoes a negative displacement from position A to position A1, point B on the roll edge moves to B1. Therefore roll edge 2
Because of the displacement of α in the radial direction, an elongation or contraction of 2πα occurs at point B, and this elongation or contraction will not be absorbed unless the roll edge 2 absorbs it. By the way, if the roll edge 2 is made of a material with low elasticity such as cloth, vertical wrinkles will occur, which will reduce the linearity of vibration and cause distortion. Furthermore, even if the material is made of a material such as urethane, which has relatively good elasticity, it is impossible to completely absorb the expansion and contraction, and the material may warp due to the force of lateral shear acting in a direction perpendicular to the axis. There is a simple drawback.

One block of VXIV blocks is formed using the twisted planes 19 and 20 as sides. This V'II! The lips form an inverted 8-shape on the surface of the support 8 in the length direction of the lips, and are continuously arranged in the circumferential direction to form wave-shaped unevenness on the surface of the support 8. Therefore, the cross section in the radial direction and the cross section in the circumferential direction of any diameter are continuous v-shaped], and since the length direction of the lip is in an inverted B shape, the elongation in the radial direction and the circumferential direction In the expansion and contraction, the twisted surfaces 19 and 20 are further twisted or loosened to absorb the expansion and contraction of the support 8, and the non-linearity in the large amplitude region is improved.

This embodiment of FIG. 3 has the advantage that mold processing is easy. Although the edge that supports the diaphragm has been described above, the damper that supports the voice coil bobbin also has the same effect.
