DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a diaphragm
having a Sencho vibrating plate or a diaphragm for resonance, IItJ, f8. Conventionally, in the case
of a speaker having a flat vibrating reed plate or a vibrating body for resonance, when a low
frequency imaging operation with a large amplitude is performed in a limited portion of the
diaphragm and stabilized throughout the diaphragm, it is difficult to Ba is 9 with double dampers
and edges holding diaphragms! 3) 2/2 page moving plate does not achieve a satisfactory effect,
the present invention is that the vibration of a large swing is not It is a peristalsis-less stable
operating bond in a speaker or a vibrating body for resonance intended to be stably performed
not only in part but on the entire surface. The arrows show an embodiment of the present
invention with reference to the drawings. As shown in both drawings, in the speaker or the
resonator for supporting the flat diaphragm 3 on the frame 1 via the edge 2 as shown in both
drawings, the rod 6 in parallel to the flat diaphragm 3. , 6. Of two pairs of rising bearings 4, 42.5
□, capable of pivotally supporting the same rotatably. Are placed on the frame 1 at intervals, and
the two pairs of rising bearings 4. . 4、.5..5! (7 rod &, each pair of both ends of the pair
is jffl-length bent in the same direction and provided in the plane width moving plate 3 in the
rising aperture 70.7s, 8 .. 8係 合 係 合 係 合 係 合 な る な る. When a part of the flat diaphragm
3 where the rising hole 81 is provided starts to vibrate greatly, one end is held in the rising hole
8 to make the rising bearing 5 □, 5. The back-to-back perforated plate is moved up and down to
reciprocate to the shaft 4 and the flat diaphragm 3 is vibrated in a stable manner without being
offset to one side. The rising bearings are also the same as described above for the rising
openings 7s and 7 * ic engaging the tips of both ends of the rod 6 □ 0 supported on the 4sK

shaft. As described above, according to the present invention, it is possible to stably vibrate the
flat diaphragm with high compliance, and to adjust the mutual JIl-friction and the respective
mass of the rising shaft bearing and the rising hole and the inserted rod. It is also possible to
control the vibration coefficient completely by applying appropriate damping to the bass
amplitude from K.
